Description

  The present invention relates to a cursor control device, a cursor control system, and a control method for a cursor control device that can improve the operability of a cursor.

  Conventionally, GUI (Graphical User Interface) such as various icons or hyperlinks are displayed on a display unit connected to a PC (personal computer). In addition, a pointing device such as a mouse or a touch pad is connected to the PC, and an instruction is given to the GUI or the like by, for example, a mouse click operation. When an instruction is given to the GUI or the like by the click operation of the mouse, the user needs to align the cursor displayed on the display unit with a desired GUI or hyperlink (that is, move the cursor on the desired GUI).

  Here, FIG. 11 is an explanatory diagram showing a state in which a click operation is performed on the GUI 111. As shown in FIG. 11, the display unit 101 displays a cursor, a GUI 111, and a GUI 112. First, when the user desires to click on the GUI 111, the user operates the mouse to cause the control device to perform processing so as to bring the cursor close to the GUI 111 and overlap the GUI 111. Then, the user can select the GUI 111 by clicking the mouse after moving the cursor on the GUI 111, and can cause the control device to execute processing associated with the GUI 111.

  However, when the GUI is small, for example, the clickable range may be narrow. Also, with a pointing device such as a touch pad, it may be difficult for some users to move the cursor. In such a case, it may be difficult for the user to move the cursor on a desired GUI.

  For this reason, in recent years, in order to improve the operability of the cursor, various devices have been applied to a control device that performs cursor control such as a PC. For example, Patent Documents 1 and 2 disclose a control device or a control method that can improve the operability of the cursor by changing the cursor movement amount in accordance with the usage status of the pointing device.

  In Patent Document 1, the resolution coefficient k indicating the ratio of the cursor movement amount to the mouse movement amount is determined with reference to the data set in advance in the area specification table and the current position coordinate data of the cursor, and a new A mouse interface having automatic resolution adjustment means for determining the position coordinates of the cursor is disclosed.

  According to this configuration, for example, the resolution coefficient k in a preset square area can be specified, and thus, for example, the cursor can be moved finely in the square area. Therefore, in the technique of Patent Document 1, since the cursor movement amount can be changed depending on the display area of the cursor, it is possible to provide the user with workability suited to the nature of the area.

  Patent Document 2 discloses a pointing processing method capable of moving a cursor over a wide range by slightly moving a pointing device such as a mouse. Specifically, in the technique of Patent Document 2, when a predetermined key is pressed, the moving direction of the mouse is determined from the moving amount of the mouse. Then, a straight line that passes through the current cursor position and runs in the determined movement direction is determined, and a process of moving the cursor to the boundary of the current area (for example, a process of moving to the boundary line of the window or GUI area) is performed. .

  According to this configuration, the user can move the cursor over a wide range (for example, to a GUI in the cursor movement direction) by moving the mouse slightly, and the user's work efficiency can be improved. it can.

  However, in the techniques of Patent Documents 1 and 2, the cursor movement amount is determined in accordance with the usage status of the pointing device, but the cursor position and the GUI position are obtained and the distance is closest to the cursor position. The GUI is not selectable. For example, Patent Document 3 discloses a technique that realizes a configuration capable of selecting a GUI at a distance closest to the cursor position.

  Patent Document 3 discloses a cursor display control method capable of easily moving a cursor on a target button key. Specifically, in the technique of Patent Document 3, when the distance between the position where the finger touches the touch screen and the position of each button key is calculated, the button key closest to the position where the finger touched is calculated based on the calculation result. Select to display the cursor on this button key.

  Here, as shown in FIG. 12, the button keys A and B are displayed on the touch screen (or display unit) 102. FIG. 12 is an explanatory diagram showing the state of the display screen when controlled by the cursor display control method shown in Patent Document 3.

  For example, as shown in FIG. 12, the control device in Patent Document 3 calculates the distance between the position of this point P and the positions of the button keys A and B, where the position where the finger touches the touch screen 102 is the point P. To do. In this case, the control device selects the button key B as the button key closest to the position of the point P as a result of the calculation. Then, as shown in FIG. 12, the control device displays a cursor at the position of the point Q on the button key B.

According to this configuration, since the cursor can be displayed on the button key closest to the position regardless of the position on the screen of the touch screen 102, the operability of the cursor is improved. Can be made.
Japanese Patent Laid-Open No. 9-251341 (published September 22, 1997) Japanese Patent Laid-Open No. 3-265920 (released on November 27, 1991) JP-A-8-272535 (released on October 18, 1996)

  However, in the technique of Patent Document 3, the position where the cursor is displayed is always on the button key closest to the position where the cursor is pointed, regardless of where the finger touches the touch screen. That is, in the technique of Patent Document 3, the cursor is not displayed at a position to be originally designated (a position where a normal cursor is displayed, and a position touched by a finger in the case of a touch screen).

  Here, for example, when the user moves the mouse while pressing the mouse click key, a cursor control device that controls a cursor such as a PC determines that a drag operation has been performed on the mouse. In this drag operation, for example, when the cursor is on a button key, the button key can be moved in accordance with the movement of the cursor (that is, movement of the mouse). In addition, when the cursor control apparatus can display, for example, a window on the screen, the position or size of the window can be changed by a drag operation.

  However, in the technique of Patent Document 3, as described above, since the position where the cursor is displayed is always on the button key, such an operation cannot be performed. That is, in the technique of Patent Document 3, when the cursor is always displayed on the button key and the cursor operation other than the selection of the button key is performed, the operability may be lowered.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a cursor control device, a cursor control system, and a control method for the cursor control device capable of improving the operability of the cursor. is there.

  In order to solve the above problems, a cursor control device according to the present invention is a cursor control device that controls a cursor displayed on a display device in accordance with a user input operation acquired by the input device. Receiving determination means for determining whether or not an input invalid signal indicating that the input invalid signal has not been acquired is received from the input device, and when the reception determining means determines that the input invalid signal has been received from the input device , An area specifying means for specifying an instruction input area that can be processed in response to a user's instruction input at a position closest to the current cursor position displayed on the display device; and the area specifying means specifies The instruction input area is provided with cursor moving means for moving the cursor from the current cursor position.

  In order to solve the above-described problem, a control method for a cursor control device according to the present invention controls a cursor displayed on a display device in accordance with a user input operation acquired by the input device. The reception invalidation step for determining whether or not an input invalid signal indicating that the user's input operation has not been acquired has been received from the input device, and the input invalid signal at the reception determination step. If it is determined that the input has been received from the input device, the region specification for specifying the instruction input region that can be processed for the user's instruction input at the position closest to the current cursor position displayed on the display device Step and a cursor moving step for moving the cursor from the current cursor position to the instruction input area specified in the area specifying step It is characterized in that it comprises a.

  According to the above configuration, when the reception determining unit determines that the input invalid signal indicating that the user's input operation has not been acquired is received from the input device, the region specifying unit starts from the current cursor position. The instruction input area at the closest position is specified. Then, the cursor moving means moves the cursor from the current cursor position to the instruction input area specified by the area specifying means. Here, the input invalid signal is received from the input device when the user's input operation to the input device is not acquired, and includes a specific signal from the input device, for example.

  As a result, the cursor control device can move the cursor to the instruction input area located closest to the current cursor position when the input invalid signal is received. For this reason, when the user desires to place the cursor on an arbitrary instruction input area, it is only necessary to move the cursor roughly to the instruction input area so as not to perform an input operation on the input device. That is, the cursor control device can move the cursor so that the cursor is aligned with the instruction input area without having to align the cursor with the instruction input area where the user desires to align the cursor. For this reason, the cursor control device can improve the operability of the cursor for the user.

  In particular, the cursor control device can improve the operability of the cursor particularly when the instruction input area is small, or when the user performs an input operation on the input device at a position away from the display device.

  Furthermore, the cursor control device according to the present invention includes a selection prohibition determining unit that determines whether selection by a user input operation is prohibited for the instruction input region specified by the region specifying unit, and the selection If the prohibition determining means determines that selection by the user's input operation is prohibited for the instruction input area, the cursor moving means may move the cursor to an area other than the instruction input area. Good.

  According to the above configuration, when the selection prohibition determining unit determines that the instruction input area is prohibited from being selected by the user's input operation, the cursor moving unit moves the cursor to an area other than the instruction input area. Move.

  As a result, even if the instruction input area is specified by the area specifying means, the cursor control device does not bring the cursor close to the instruction input area when selection to the instruction input area is prohibited. Can be. That is, the cursor control device can further improve the operability of the cursor.

  Furthermore, the cursor control device according to the present invention further comprises a time measuring unit for measuring a time during which the cursor displayed on the display device is stopped, and the region specifying unit is provided for a time set in advance by the time measuring unit. When the time is counted, the instruction input area may be specified.

  According to the above configuration, the area specifying unit specifies the instruction input area when the time measuring unit measures time for a preset time. Thereby, the cursor control device can prevent the cursor from being moved to the instruction input area for a time during which the user is expected to further move the cursor. For this reason, the cursor control device can further improve the operability of the cursor.

  Furthermore, a cursor control system according to the present invention includes the cursor control device described above, and an input device that acquires an input operation of a user and transmits input data indicated by the input operation to the cursor control device. A cursor control system, wherein the input device determines whether or not the user's input operation has been acquired, and if the acquisition determination unit determines that the user's input operation has not been acquired, An input invalid signal creating means for creating an input invalid signal indicating that the user's input operation is not acquired is provided.

  According to the above configuration, the cursor control system includes the cursor control device that controls the cursor displayed on the display device, and the input device that transmits the input data indicated by the user's input operation to the cursor control device.

  When the acquisition determining unit determines that the user's input operation is not acquired, the input device generates an input invalid signal indicating that the input invalid signal generating unit has not acquired the user's input operation. . Then, the input device transmits the created input invalid signal to the cursor control device. When the cursor control device receives the input invalid signal from the input device (that is, when the reception determining unit determines that the input invalid signal has been received), the region specifying unit specifies the instruction input region and the current cursor position Move the cursor from.

  Thus, when the cursor control device receives an input invalid signal that is generated when it is determined that the input device has not acquired the user's input operation, the instruction input area that is closest to the current cursor position You can move the cursor to. For this reason, when the user desires to place the cursor on an arbitrary instruction input area, it is only necessary to move the cursor roughly to the instruction input area so as not to perform an input operation on the input device. That is, the cursor control device can move the cursor so that the cursor is aligned with the instruction input area without having to align the cursor with the instruction input area where the user desires to align the cursor. For this reason, the cursor control device can improve the operability of the cursor for the user.

  As described above, the cursor control device according to the present invention includes a reception determination unit that determines whether or not an input invalid signal indicating that a user input operation has not been acquired has been received from the input device, and the reception When the determination means determines that the input invalid signal has been received from the input device, it is possible to perform processing for the user's instruction input that is closest to the current cursor position displayed on the display device. A region specifying unit that specifies a specific instruction input region, and a cursor moving unit that moves the cursor from the current cursor position to the instruction input region specified by the region specifying unit.

  Further, the control method of the cursor control device according to the present invention includes a reception determination step of determining whether or not an input invalid signal indicating that the user's input operation has not been acquired is received from the input device, and the reception When it is determined in the determination step that the input invalid signal has been received from the input device, processing for a user instruction input at a position closest to the current cursor position displayed on the display device may be performed. An area specifying step for specifying a possible instruction input area and a cursor moving step for moving the cursor from the current cursor position to the instruction input area specified in the area specifying step.

  Therefore, the cursor control device can move the cursor so as to align the cursor with the instruction input area without positioning the cursor with the instruction input area where the user desires to align the cursor. For this reason, the cursor control device has an effect of improving the operability of the cursor for the user.

Embodiment 1
One embodiment of the present invention is described below with reference to FIGS.

[Outline of transmission / reception system]
First, the outline of the present invention will be described with reference to FIG. FIG. 2 is an explanatory diagram showing an example of an outline of the transmission / reception system 1 according to the present invention. As shown in FIG. 2, the transmission / reception system (cursor control system) 1 includes a remote controller (input device) 2, a mouse (input device) 3, a display unit (display device) 4, and a PC unit (cursor control device) 5. Yes.

  In the transmission / reception system 1, the remote controller 2 and the PC unit 5 perform transmission / reception with, for example, an RF (radio frequency) signal. Further, the mouse 3 and the display unit 4 are connected to the PC unit 5 by a cable or the like. The display unit 4 and the PC unit 5 are connected by, for example, a DVI (Digital Visual Interface) cable.

  The display unit 4 displays contents based on the data transmitted from the PC unit 5. For example, the display unit 4 displays a GUI, a hyperlink, a cursor, and the like. In FIG. 2, the display unit 4 displays a cursor (arrow), a GUI 41a, and a GUI 41b.

  The display unit 4 may not only display the content of data transmitted from the PC unit 5 but also have a TV function. In this case, the display unit 4 is configured to receive an operation command by receiving, for example, an IR (Infrared Ray, for example, IrSimple) signal from the remote controller 2. That is, since the display unit 4 is directly controlled by the remote controller 2, it is possible to view a TV broadcast while operating the PC.

  As shown in FIG. 2, the remote control 2 includes a transmission unit 21 on a surface capable of transmitting operation data to the PC unit 5 when the normal remote control 2 is operated. In addition, the remote controller 2 includes a touch pad 22 and a click key 23 on the upper surface (the surface on the side on which the user of the remote controller 2 operates). The remote controller 2 acquires a user's input operation using the touch pad 22 and the click key 23, and transmits input data indicated by the input operation to the PC unit 5 via the transmission unit 21.

  The transmission unit 21 converts input data generated by an input data creation unit 26 described later into, for example, an RF signal pattern and transmits the RF signal pattern to the PC unit 5.

  The touch pad 22 detects which position on the touch pad 22 is touched when a finger touches the surface (the surface exposed to the outside of the remote controller 2). Examples of the touch pad 22 include a capacitance type touch panel and a resistive film type touch pad. Here, the capacitive touch pad detects that the amount of internal charges changes when a finger touches the surface of the touch pad 22, thereby detecting the movement of the finger on the touch pad 22. Also, the resistive film type touch pad is a method in which a conductive thin film is applied to the surface of the touch pad 22 and a film attached to the surface at a slight interval to detect whether or not electricity has passed through the thin film. To do.

  The click key 23 is configured by a push switch such as a mechanical switch, for example, and is configured to be pressed by the user. When the click key 23 is pressed by the user, for example, the selection processing of the GUI displayed on the display unit 4, the processing associated with the GUI, or the processing due to the drag operation is performed on the PC unit 5. Can be made. The click key 23 has the same configuration and function as the click key normally provided in the mouse 3 or the like, for example.

  The mouse 3 is for controlling a cursor displayed on the display unit 4 as with the touch pad 22. The mouse 3 also includes a click key (not shown, but having the same configuration and function as the click key 23) that can be pressed by the user. Thereby, the mouse 3 can cause the PC unit 5 to execute a cursor movement process, a GUI selection process by a click operation, and the like when operated by the user.

  As shown in FIG. 2, when receiving input data from the remote controller 2 or the mouse 3, the PC unit 5 controls, for example, a GUI and a cursor displayed on the display unit 4 based on the input data. That is, the PC unit 5 controls a GUI, a cursor, and the like displayed on the display unit 4 in accordance with a user input operation acquired by the remote controller 2 or the mouse 3. The PC unit 5 includes a receiving unit 51. The receiving unit 51 receives input data transmitted from the remote controller 2 and transmits this input data to an input data converting unit 52 described later.

  As described above, in the remote controller 2, coordinate input can be performed by touching the touch pad 22 with a finger, and therefore, for example, the PC unit 5 can execute processing such as moving the cursor displayed on the display unit 4. it can. Further, since the remote controller 2 includes the click key 23, the PC unit 5 can execute processes such as a click operation and a drag operation by the user.

  Note that the touch pad 22 may have the same function as the click key 23. In this case, the remote controller 2 can cause the PC unit 5 to execute processing such as a click operation even when the surface of the touch pad 22 is lightly tapped by the user.

  In the transmission / reception system 1, the remote controller 2 is configured to be able to remotely operate the PC unit 5. However, the present invention is not limited to this, and the remote controller 2 and the PC unit 5 may be configured integrally. That is, as shown in FIG. 3, the PC main body (cursor control system) 1a includes an input unit (input device) 2a in which the remote controller 2 in the transmission / reception system 1 includes a touch pad 22 and a click key 23. 2a may be configured integrally with the PC unit 5. FIG. 3 is an explanatory diagram showing an example of an outline of the PC main body 1a showing a form different from the transmission / reception system 1 according to the present invention.

[Schematic configuration of remote control]
Next, a schematic configuration of the remote controller 2 will be described with reference to FIG. FIG. 1 is a block diagram showing a schematic configuration of a remote controller 2 and a PC unit 5 in a transmission / reception system 1 of the present invention. As shown in FIG. 1, the remote controller 2 includes a transmission unit 21, a touch pad 22, a click key 23, a movement amount detection unit 24, a key operation detection unit 25, and an input data creation unit (acquisition determination unit, input invalid signal creation unit). 26. Since the transmission unit 21, the touch pad 22, and the click key 23 have been described above, description thereof is omitted here.

  The movement amount detection unit 24 detects the movement amount when the finger touches the surface of the touch pad 22 and moves on the surface of the touch pad 22. Then, the movement amount detection unit 24 transmits the detected movement amount to the input data creation unit 26 as movement amount data.

  The key operation detection unit 25 detects whether or not a finger touches the touch pad 22 or the click key 23 (that is, a contact or non-contact state). Then, the key operation detection unit 25 transmits the detection result from the touch pad 22 or the click key 23 to the input data creation unit 26 as key operation information. At this time, the key operation detection unit 25 determines whether the key operation information is obtained from the touch pad 22 or the key operation information obtained from the click key 23, together with the key operation information. Send.

  The key operation information indicates whether or not a finger has touched the touch pad 22 or the click key 23 (that is, whether or not an input operation has been performed by the user). For this reason, the key operation information indicates that the key operation is valid when the finger touches the touch pad 22 or the click key 23, while the key operation is invalid when the finger is not touching.

  The input data creation unit 26 creates input data to be input to the PC unit 5 for the PC unit 5 to perform processing. For example, the input data creation unit 26 creates the input data from the movement amount data received from the movement amount detection unit 24 and the key operation information detected from the key operation detection unit 25. Then, the input data creation unit 26 transmits the created input data to the PC unit 5 via the transmission unit 21.

  Here, the input data creation unit 26 could not detect the movement of the finger from the movement amount detection unit 24 when the user's finger was released from the click key 23 after the click operation was performed on the click key 23. In this case, the movement amount data indicating the movement amount 0 is received from the movement amount detection unit 24 and the key operation information indicating that the key operation is invalid is received from the key operation detection unit 25. On the other hand, the input data creation unit 26 also receives movement amount data indicating movement amount 0 and key operation information indicating invalid key operation even when the finger is released from the touch pad 22.

  At this time, when the input data creation unit 26 receives the key operation information indicating that the key operation is invalid from the key operation detection unit 25, the input data creation unit 26 obtains the key operation information from the touch pad 22 or the click key 23. To determine whether Although not shown, the key operation detection unit 25 includes a click key operation detection unit that detects an operation on the click key 23 and a tap operation detection unit that detects a tap operation on the touch pad 22. Also good. When the input data creation unit 26 determines that the key operation information is obtained from the touch pad 22, the input data including the “movement amount 0 and key operation invalid” state is continuously transmitted twice to the transmission unit 21. To the PC unit 5.

  Note that the transmission unit 21 can receive the time interval at which the input data creation unit 26 continuously transmits the input data twice when the finger is released from the touch pad 22 (or the time interval at which the input data is generated twice). It may be more than the minimum interval. For example, the time interval is an interval when data is continuously transmitted from the input data creation unit 26 to the transmission unit 21 when an operation for moving the cursor by the user is performed on the touch pad 22. It can be the same.

  If the input data creation unit 26 determines that the key operation information is obtained from the touch pad 22, the input data including the “movement amount 0 and key operation invalid” state is transmitted twice to the PC unit 5 in succession. Instead, input data including a TPbreak signal may be transmitted. That is, the input data creation unit 26 may create input data including that the finger has been removed from the touch pad 22 and transmit it to the PC unit 5.

  That is, the input data creation unit 26 determines whether or not the user's input operation has been acquired, and if it is determined that the input operation has not been acquired, the input invalidity indicating that the user's input operation has not been acquired. Creating a signal.

[Schematic configuration of PC section]
Next, a schematic configuration of the PC unit 5 will be described with reference to FIG. As shown in FIG. 1, the PC unit 5 includes a receiving unit 51, an input data converting unit 52, an input data analyzing unit 53, an input data determining unit (reception determining unit) 54, a timer (time measuring unit) 55, a cursor coordinate processing unit. (Cursor moving means) 56, GUI selection processing section 57, GUI determining section (area specifying means) 58, GUI selecting section (selection prohibition determining means) 58 a, GUI information storage section 59, and display video creation section 60. Since the receiving unit 51 has been described above, the description thereof is omitted here.

  The input data conversion unit 52 converts the input data transmitted from the remote controller 2 into data that can be analyzed by the input data analysis unit 53, and transmits the converted input data to the input data analysis unit 53. The input data conversion unit 52 may be omitted when the input data transmitted from the remote controller 2 is data that can be analyzed by the input data analysis unit 53.

  The input data analysis unit 53 analyzes what information the input data converted by the input data conversion unit 52 has. That is, the input data analysis unit 53 extracts the movement amount indicated by the movement amount data and the key operation valid / invalid state indicated by the key operation information included in the input data. Then, the input data analysis unit 53 transmits the analysis result (extracted result) to the input data determination unit 54 as analysis data.

  The input data determination unit 54 determines what state the input data received from the remote controller 2 indicates. Specifically, when the input data determination unit 54 receives the analysis data from the input data analysis unit 53, the input data determination unit 54 indicates what state the analysis data indicates (whether the movement amount is 0 and the key operation). Whether or not is valid).

  When it is determined that the received analysis data indicates the “movement amount 0 and key operation invalid” state, the input data determination unit 54 determines whether the analysis data is received twice in succession from the touch pad 22. It is determined whether or not the finger is removed. The input data determination unit 54 transmits a GUI determination signal to the GUI determination unit 58 when it is determined that the finger has been removed from the touch pad 22. When the input data determination unit 54 determines that the finger has been removed from the touch pad 22, the input data determination unit 54 transmits a time measurement start signal to the timer 55 to activate the timer 55.

  On the other hand, if the input data determination unit 54 determines that the received analysis data indicates a state in which “the movement amount is 0 and the key operation is not invalid”, this analysis data is transmitted to the cursor coordinate processing unit 56. .

  The timer 55 measures the time from when the input data determination unit 54 determines that the finger has been released from the touch pad 22. Specifically, the timer 55 starts timing when it receives a timing start signal from the input data determination unit 54, and ends timing when it receives a timing stop signal. In addition, a predetermined time is set in advance in the timer 55, and when the timer 55 counts up to a preset time, the timer 55 transmits a timing end signal to the input data determination unit 54 and ends the timing.

  This timing stop signal is generated when the input data determination unit 54 receives the analysis data indicating the “movement amount 0 and key operation invalid” state only once, or the analysis indicating the state “movement amount 0 and key operation is not invalid”. When data is received, it is transmitted from the input data determination unit 54.

  The time set in advance in the timer 55 is sufficiently longer than the operation time when the cursor is moved largely (or faster), that is, the time from when the finger is released from the touch pad 22 until the touch pad 22 is touched again. For example, it is set to 0.5 seconds.

  When the cursor coordinate processing unit 56 receives the analysis data from the input data determination unit 54, the cursor coordinate processing unit 56 obtains the position coordinate of the cursor to be moved from the analysis data, and generates cursor position data indicating the position coordinate of the cursor for display image creation To the unit 60.

  The cursor coordinate processing unit 56 transmits a GUI selection processing start signal to the GUI selection processing unit 57 when the received analysis data indicates that the key operation is valid and the cursor is on the GUI. This GUI selection processing start signal is a signal for starting processing by the GUI selection processing unit 57.

  On the other hand, if the received analysis data indicates that the key operation is valid and the cursor is not on the GUI, the cursor coordinate processing unit 56 displays the cursor locus together with the cursor position data indicating the obtained cursor position coordinates. A trajectory display signal to be displayed on the unit 4 is transmitted to the display video creation unit 60.

  Further, when the input data determination unit 54 transmits a GUI determination signal to the GUI determination unit 58, the cursor coordinate processing unit 56 determines the position of the cursor to be moved from the cursor movement amount transmitted from the GUI determination unit 58. Find the coordinates. Then, the cursor coordinate processing unit 56 transmits cursor position data indicating the position coordinates of the cursor to the display video creating unit 60.

  When the GUI selection processing unit 57 receives a GUI selection processing start signal from the cursor coordinate processing unit 56, the GUI selection processing unit 57 performs GUI selection processing on the GUI on which the cursor is placed. This GUI selection processing is performed in accordance with the GUI specifications. For example, the display (color, shape, etc.) of the GUI or a part other than the GUI is changed, another page is jumped, or another window is opened. It is something to do. Further, the GUI selection processing unit 57 is not limited to the change on the display screen of the display unit 4 and may be configured to be able to generate any phenomenon that can be controlled from the PC unit 5. Then, the GUI selection processing unit 57 transmits a GUI selection processing signal indicating the processing result of the GUI selection processing to the display video creation unit 60.

  When the GUI determination unit 58 receives a GUI determination signal from the input data determination unit 54, the GUI determination unit 58 performs a selection target GUI determination process. Then, the GUI determination unit 58 transmits the cursor movement amount obtained as a result of the selection target GUI determination process to the cursor coordinate processing unit 56. The selection target GUI determination process by the GUI determination unit 58 will be described later.

  In the selection target GUI determination process, the GUI selection unit 58a determines whether or not the GUI that is closest to the current cursor position is a selectable GUI. Specific processing of the GUI selection unit 58a will be described later together with selection target GUI determination processing.

  The GUI information storage unit 59 stores information on the GUI (or hyperlink) displayed on the display unit 4. For example, GUI coordinate information such as all coordinates, vertex coordinates, center coordinates, etc. constituting the GUI. , Number i or selection valid / invalid is stored in association with each GUI.

  The display video creation unit 60 creates a display screen corresponding to the data transmitted from the cursor coordinate processing unit 56 and the GUI selection processing unit 57, and transmits the created result to the display unit 4 as a display screen creation signal. Thereby, the PC unit 5 can display the processing result in the PC unit 5 on the display unit 4.

  The PC unit 5 is configured to receive input data including a TPbreak signal instead of receiving input data including “movement amount 0 and key operation invalid” twice when the finger is released from the touch pad 22. May be.

[Input data analysis processing in the PC according to the input operation to the touchpad (part 1)]
Next, an input data analysis process in the PC unit 5 according to an input operation to the touch pad 22 will be described. FIG. 4 is a flowchart showing the flow of input data analysis processing in the PC unit 5 in response to an input operation on the touch pad 22. In the process illustrated in FIG. 4, when the PC unit 5 receives a signal indicating that the user's finger has been removed from the touch pad 22 (an input indicating a “movement amount 0 and key operation invalid” state twice in succession). When data is received), the process proceeds to selection target GUI determination processing.

  First, when receiving some input data from the remote controller 2, the PC unit 5 starts an input data analysis process shown in FIG.

  Specifically, when an input operation (including a case where the user's finger is released) is performed on the touch pad 22, the movement amount detection unit 24 detects the movement amount, and the key operation detection unit 25 detects that the touch pad 22 or It is detected whether or not a finger touches the click key 23. Then, the movement amount detection unit 24 transmits the result detected from the touch pad 22 to the input data creation unit 26 as movement amount data. Similarly, the key operation detection unit 25 transmits the result detected from the touch pad 22 or the click key 23 to the input data creation unit 26 as key operation information.

  The input data creation unit 26 creates input data to be input to the PC unit 5 from the movement amount data received from the movement amount detection unit 24 and the key operation information received from the key operation detection unit 25. Then, the input data creation unit 26 transmits the created input data to the PC unit 5 via the transmission unit 21.

  In the PC unit 5, when the receiving unit 51 receives the input data transmitted from the remote controller 2, the received input data is transmitted to the input data converting unit 52. When receiving the input data, the input data conversion unit 52 converts the input data into data that can be analyzed by the input data analysis unit 53, and transmits the converted input data to the input data analysis unit 53.

  When the input data analysis unit 53 receives the input data converted by the input data conversion unit 52, the input data analysis unit 53 analyzes what information the input data has (S1). That is, the input data analysis unit 53 receives the movement amount indicated by the movement amount data detected by the movement amount detection unit 24 of the remote controller 2 and the key operation information detected by the key operation detection unit 25 from the received input data. The key operation valid / invalid state shown is extracted. Then, the input data analysis unit 53 transmits the analysis result, that is, the movement amount and key operation information extracted from the input data to the input data determination unit 54 as analysis data.

  When the input data determination unit 54 receives the analysis data from the input data analysis unit 53, the input data determination unit 54 determines whether or not the analysis data indicates the state of “movement amount 0 and key operation invalid (that is, no movement operation and no selection operation)”. Is determined (S2).

  When the input data determination unit 54 determines that the analysis data indicates the “movement amount 0 and key operation invalid” state (Yes in S2), the analysis data stored in the input data determination unit 54 indicates that “movement amount 0”. In addition, it is determined whether or not the data indicates a “key operation invalid” state (S3).

  When the input data determination unit 54 determines that the stored analysis data is not data indicating the “movement amount 0 and key operation invalid” state (No in S3), the stored analysis data is received this time. Then, the analysis data is rewritten to the analysis data indicating the "movement amount 0 and key operation invalid" state, and the analysis data received this time is stored in the input data determination unit 54 (S4). That is, in the case of No in S <b> 3, the input data determination unit 54 indicates that the analysis data indicating the “movement amount 0 and key operation invalid” state is the analysis data received for the first time, or the finger is released from the click key 23. Judge that it is. Thereafter, the PC unit 5 ends the input data analysis process.

  On the other hand, when the input data determination unit 54 determines that the stored analysis data is data indicating the “movement amount 0 and key operation invalid” state (Yes in S3), the input data determination unit 54 transmits the data. The analysis data is recognized as the data indicating the “movement amount 0 and key operation invalid” state, which is the same as the stored analysis data. That is, in the case of Yes in S3, the input data determination unit 54 recognizes that the analysis data indicating the “movement amount 0 and key operation invalid” state has been received twice in succession, whereby the finger is released from the touch pad 22. Judge that it is.

  When the finger is released from the click key 23 after the click operation is performed on the click key 23, the input data creation unit 26 of the remote controller 2 receives the input data including “movement amount 0 and key operation invalid” in the PC unit. 5 is transmitted. For this reason, even when the finger is released from the click key 23, the input data determination unit 54 receives the analysis data indicating the “movement amount 0 and key operation invalid” state.

  However, when the finger is released from the touch pad 22, the remote controller 2 continuously transmits input data including “movement amount 0 and key operation invalid” twice. For this reason, the input data determination unit 54 determines that the finger has moved away from the touch pad 22 when receiving the analysis data indicating the “movement amount 0 and key operation invalid” state twice in succession, so that the click key 23 It can be distinguished from when the finger is released.

  When it is determined that the finger has moved away from the touch pad 22, the input data determination unit 54 determines whether or not there is an input operation to the touch pad 22 within a preset time (here, 0.5 seconds) ( S5). Specifically, when receiving the analysis data indicating the “movement amount 0 and key operation invalid” state twice consecutively, the input data determination unit 54 transmits a time measurement start signal to the timer 55 and activates the timer 55. .

  The timer 55 starts timing at the timing when the timing start signal is received, and the input data determination unit 54 indicates that the movement amount is 0 and the key operation is not invalid (that is, the movement amount is present (the movement amount is not 0) or the key operation is valid). When the analysis data indicating the “)” state is received, the time measurement is terminated by receiving a time measurement stop signal from the input data determination unit 54. Further, when the timer 55 does not receive the time stop signal from the input data determination unit 54, the timer 55 transmits a time measurement end signal to the input data determination unit 54 and ends the time measurement when it measures time for a preset time.

  Here, the user causes the PC unit 5 to move the cursor displayed on the display unit 4 by moving the finger touching the touch pad 22 so as to stroke the surface of the finger. At this time, when the user moves the cursor greatly, for example, the size of the touch pad 22 is limited, so that after moving the finger, the finger is released once, and then the touch pad 22 is touched again to move the finger. The act will be repeated. That is, the user may intend to cause the PC unit 5 to further perform the process of moving the cursor by touching the touch pad 22 again even when the finger is released from the touch pad 22. .

  For this reason, in the process of S4, the input data determination unit 54 receives the analysis data indicating the state “the amount of movement is 0 and the key operation is not invalid” within a preset time after the timer 55 is activated. It is determined whether or not. As a result, the PC unit 5 can prevent the cursor from being moved to the instruction input area for a time during which the user is expected to further move the cursor.

  When it is determined that there is no input operation to the touch pad 22 within a preset time, the input data determination unit 54 has not received analysis data indicating a state of “movement amount 0 and key operation is not invalid”. Is determined (Yes in S5), a GUI determination signal is transmitted to the GUI determination unit 58. When receiving the GUI determination signal, the GUI determination unit 58 performs a selection target GUI determination process (S6). Thereafter, the PC unit 5 ends the input data analysis process. The selection target GUI determination process performed by the GUI determination unit 58 will be described later.

  On the other hand, when it is determined that the input operation to the touch pad 22 has been performed within a preset time, the input data determination unit 54 has received analysis data indicating a state where “the movement amount is 0 and the key operation is not invalid”. (No in S5), the process returns to S1.

  By the way, in the process of S2, the input data determination unit 54 stores the analysis data in the input data determination unit 54 when it is not analysis data indicating the “movement amount 0 and key operation invalid” state (No in S2) ( S7). In other words, the input data determination unit 54 stores analysis data indicating a state “the amount of movement is 0 and the key operation is not invalid”.

  The input data determination unit 54 is analysis data indicating that the analysis data received from the input data analysis unit 53 is “with movement amount and key operation invalid (that is, with movement operation and no selection operation)”. It is determined whether or not (S8). When the input data determination unit 54 determines that the analysis data indicates the “movement amount and key operation invalid” state (Yes in S8), the input data determination unit 54 transmits the analysis data to the cursor coordinate processing unit 56.

  When receiving the analysis data, the cursor coordinate processing unit 56 obtains the position coordinates of the cursor to be moved from the movement amount indicated by the movement amount data included in the analysis data (S9). Then, the cursor coordinate processing unit 56 transmits the obtained position coordinates of the cursor to the display video creation unit 60 as cursor position data. Upon receiving the cursor position data, the display video creation unit 60 creates a display screen for displaying the cursor at the position indicated by the cursor position data, and transmits a display screen creation signal to the display unit 4. Thereby, the PC unit 5 can display the cursor on the display unit 4 at the position obtained by the cursor coordinate processing unit 56. The PC unit 5 ends the input data analysis process when the process of S9 ends.

  On the other hand, when the input data determination unit 54 determines that the analysis data is not analysis data indicating the “movement amount exists and key operation invalid” state (No in S8), the analysis data received from the input data analysis unit 53 indicates that “movement amount It is determined whether or not the analysis data indicates “0 and key operation valid (ie, no movement operation and no selection operation)” (S10). When the input data determination unit 54 determines that the analysis data indicates the “movement amount 0 and key operation enabled” state (Yes in S10), the input data determination unit 54 transmits the analysis data to the cursor coordinate processing unit 56.

  The cursor coordinate processing unit 56 recognizes that the key operation is valid from the key operation information included in the analysis data. At this time, the cursor coordinate processing unit 56 reads all coordinates constituting the GUI (or hyperlink) displayed on the display unit 4 and stored in the GUI information storage unit 59. Then, the cursor coordinate processing unit 56 determines whether or not the current cursor position coordinate matches any of the coordinates of the read GUI, and if it is determined to match, the cursor is displayed on the GUI. Judge that

  Note that the coordinates of the GUI that the cursor coordinate processing unit 56 reads from the GUI information storage unit 59 may be specific coordinates of the GUI (for example, center coordinates or vertex coordinates) instead of all the coordinates that constitute the GUI. Further, if the area occupied by the GUI on the display screen of the display unit 4 is known in advance, the cursor coordinate processing unit 56 can specify all the coordinates even if it is not configured to read all the coordinates. For example, when it is known that the area occupied by the GUI is a rectangular area, the cursor coordinate processing unit 56 determines the absolute coordinates of one vertex constituting the rectangular area and the vertexes on the diagonal line of the vertex. By reading the absolute coordinates or the relative coordinates viewed from the vertex from the GUI information storage unit 59, it is possible to specify all the coordinates of the GUI.

  When the key operation information indicates that the key operation is valid and the cursor is displayed on the GUI, the cursor coordinate processing unit 56 outputs a GUI selection processing start signal for causing the GUI selection processing unit 57 to perform processing. The data is transmitted to the selection processing unit 57. When receiving the GUI selection processing start signal, the GUI selection processing unit 57 performs GUI selection processing on the GUI on which the cursor is placed (S11). Then, the GUI selection processing unit 57 transmits a GUI selection processing signal indicating the result of the GUI selection processing to the display video creation unit 60. When receiving the GUI selection processing signal, the display video creation unit 60 creates a display screen indicated by the GUI selection processing signal and transmits the display screen creation signal to the display unit 4.

  As a result, the PC unit 5 can cause the display unit 4 to display the result of the GUI selection process in accordance with the GUI specification for the GUI on which the cursor is placed. At this time, the cursor coordinate processing unit 56 receives the analysis data including the movement amount 0, and therefore, the position coordinate of the movement destination cursor is the same as the current cursor position coordinate. That is, the PC unit 5 displays the cursor on the display unit 4 while fixing the position of the cursor. The PC unit 5 ends the input data analysis process when the process of S11 ends.

  On the other hand, when the input data determination unit 54 determines that the analysis data does not indicate the “movement amount 0 and key operation enabled” state (No in S10), the analysis data received from the input data analysis unit 53 indicates that the “movement amount” It is determined that the data is analysis data indicating that the state is “Yes and key operation is valid (ie, there is a movement operation and there is a selection operation)” (S12). Then, the input data determination unit 54 transmits the analysis data at this time to the cursor coordinate processing unit 56.

  When receiving the analysis data, the cursor coordinate processing unit 56 obtains the position coordinates of the cursor to be moved from the movement amount indicated by the movement amount data included in the analysis data. Then, the cursor coordinate processing unit 56 transmits the position coordinates of the cursor to the display video creation unit 60 as cursor position data.

  When the cursor coordinate processing unit 56 recognizes that the key operation is valid from the key operation information included in the analysis data, the cursor coordinate processing unit 56 reads all coordinates constituting the GUI stored in the GUI information storage unit 59 and obtains the calculated cursor. It is determined whether or not the position coordinates of the same and any of all the coordinates constituting the GUI match.

  The cursor coordinate processing unit 56 transmits a GUI selection processing start signal to the GUI selection processing unit 57 when it is determined that the calculated position coordinate of the cursor matches any of the coordinates constituting the GUI. Then, the GUI selection processing unit 57 performs GUI selection processing on the GUI on which the cursor is placed, and transmits a GUI processing signal indicating the result of this GUI selection processing to the display video creation unit 60, as in S11.

  When the display video creation unit 60 receives the cursor position data from the cursor coordinate processing unit 56 and also receives the GUI processing signal from the GUI selection processing unit 57, the display video creation unit 60 creates a display screen indicated by the cursor position data and the GUI processing signal. As a result, when the cursor is on the GUI, the PC unit 5 can cause the display unit 4 to display a state in which the GUI for which the GUI selection process has been performed is moved. That is, the PC unit 5 can perform a drag operation process on the GUI on which the cursor is placed (S13).

  On the other hand, if the cursor coordinate processing unit 56 determines that the obtained cursor position coordinates do not match any of the coordinates constituting the GUI, the cursor position indicating the cursor position coordinates is displayed on the display image creation unit 60. In addition to transmitting data, a locus display signal for displaying the locus of the cursor on the display unit 4 is transmitted.

  Upon receiving the cursor position data and the trajectory display signal from the cursor coordinate processing unit 56, the display video creation unit 60 creates a display screen indicated by the cursor position data and the trajectory display signal. Thereby, when there is no cursor on the GUI, the PC unit 5 can cause the display unit 4 to display a locus along with the cursor. That is, the PC unit 5 can perform a range designation process for designating a range in which the cursor has moved. The PC unit 5 ends the input data analysis process when the process of S13 ends.

[Selection GUI determination process]
Here, the process of S6 shown in FIG. 4, that is, the selection target GUI determination process performed by the GUI determination unit 58 will be described with reference to FIG. FIG. 5 is a flowchart showing a flow of selection target GUI determination processing performed by the GUI determination unit 58. This selection target GUI determination process is a process for determining the GUI closest to the current cursor position. However, the selection target GUI determination process is not limited to the GUI, and is a process for inputting a user instruction by positioning the cursor such as a hyperlink. Any area can be used as long as it can be input.

  When the input data determination unit 54 receives the analysis data indicating the “movement amount 0 and key operation invalid” state twice in succession and is timed by the timer 55 for a preset time, the GUI determination unit 58 A GUI determination signal is transmitted to When the GUI determination unit 58 receives the GUI determination signal, the GUI determination unit 58 proceeds to a selection target GUI determination process. The GUI displayed on the display unit 4 is uniquely and appropriately numbered i (1 ≦ i ≦ n, i is an integer, and n is the number of GUIs displayed on the display unit 4). It is stored in the GUI information storage unit 59 in association with each GUI.

  First, the GUI determination unit 58 sets the GUI number Gno when the number i = 1, the minimum distance Dmin between the center coordinates of the GUI and the cursor position coordinates to a predetermined value, and the minimum distance Dmin becomes 0. (S21). The predetermined value is the maximum distance when the PC unit 5 moves the cursor in the selection target GUI determination process, that is, the maximum cursor movement amount when the GUI determination unit 58 performs the process of moving the cursor. Value. For example, when the predetermined value is 100, the GUI determination unit 58 performs a process of moving the cursor when it is determined that there is no GUI within the distance 100 from the current cursor position displayed on the display unit 4. There is nothing. Further, in the selection target GUI determination process, the PC unit 5 performs a process of moving the cursor on all GUIs on the screen of the display unit 4 (that is, the GUI determination unit 58 sets the GUI closest to the current cursor position). In some cases, the process is performed so as to be moved. At this time, the predetermined value may be a value sufficiently larger than any distance between the center coordinates of each GUI and the position coordinates of the cursor, and is set to a diagonal distance of the display unit 4 (display screen), for example. .

  Next, the GUI determination unit 58 determines whether or not the position coordinates (X, Y) of the cursor are coordinates on the GUI (S22). Specifically, when the GUI determination unit 58 receives the GUI determination signal, the GUI determination unit 58 acquires the position coordinates (X, Y) of the cursor from the cursor coordinate processing unit 56, and all the coordinates constituting the GUI from the GUI information storage unit 59. Is read for each GUI. Then, the GUI determination unit 58 determines whether the cursor position coordinates (X, Y) match the GUI by determining whether or not the cursor position coordinates (X, Y) coincide with all the coordinates constituting each GUI. It is determined whether it is displayed above.

  When the GUI determining unit 58 determines that the cursor position coordinates (X, Y) are displayed on the GUI (No in S22), the distance between the cursor position coordinates (X, Y) and the center coordinates of the GUI D (i) is obtained (S23). Specifically, the GUI determination unit 58 first reads all coordinates constituting a GUI (GUI (i)) with a number i, and calculates the average value of each of the x and y coordinates from the values of all the coordinates. And the average value of the x and y coordinates is set as the GUI center coordinates (Gx (i), Gy (i)).

  The GUI determining unit 58 may be configured not to read all coordinates when the characteristics of the area occupied by the GUI on the display screen of the display unit 4 are known in advance. For example, when it is known that the area occupied by the GUI is a rectangular area, the GUI determination unit 58 obtains the coordinates of one vertex and the coordinates of the vertex on the diagonal of the vertex from the GUI information storage unit 59. The coordinates indicating the center point of these two vertices may be obtained as the center coordinates of the GUI. In addition, although the center coordinates of the GUI are obtained here, the present invention is not limited to this, and any coordinates may be used as long as they are marks constituting the GUI.

Then, the GUI determination unit 58 uses the cursor position coordinates (X, Y) and the GUI center coordinates (Gx (i), Gy (i)) acquired from the cursor coordinate processing unit 56, for example,
Distance D (i) = ((Gx (i) −X) ² + (Gy (i) −Y) ² ) ^1/2
The distance D is obtained from Note that the GUI determination unit 58 is not limited to the above formula,
Distance D (i) = | Gx (i) −X | + | Gy (i) −Y | (Manhattan distance)
May be used to determine the distance D (i). Instead of obtaining the distance D (i),
Distance D (i) ² = (Gx (i) −X) ² + (Gy (i) −Y) ²
, And this distance D (i) ² may be used. In this case, the predetermined value of the minimum distance value Dmin set in the process of S1 is also set to a value that takes D (i) ² into account (for example, the square of the diagonal line of the display screen).

  For example, when the number i = 1 is set, the GUI determination unit 58 uses the center coordinates (Gx (1), Gy (1)) of the GUI (1) with the number i = 1 and the cursor position coordinates ( A distance D (1) from X, Y) is obtained.

  Next, the GUI determining unit 58 compares the calculated distance D (i) with the minimum distance value Dmin, and the distance D (i) is smaller than the minimum distance value Dmin. It is determined whether or not (S24). Note that in S24, the GUI determination unit 58 may determine whether or not the obtained distance D (i) is equal to or less than the set minimum distance Dmin.

  When determining that the obtained distance D (i) is smaller than the set distance minimum value Dmin (Yes in S24), the GUI determining unit 58 sets the calculated distance D (i) to the minimum value Dmin. At the same time, the GUI number Gno = i when the minimum value Dmin is set is set (S25). Then, the GUI determining unit 58 sets the number i = i + 1 assigned to each GUI (S26), and determines whether the number i is equal to or less than the number n of GUIs displayed (S27). ).

  When the GUI determining unit 58 determines that the number i is equal to or less than the number n of GUIs (Yes in S27), the GUI determining unit 58 returns to the process of S23. Note that if the GUI determination unit 58 determines that the obtained distance D (i) is equal to or greater than the minimum distance Dmin that has been set (No in S24), the process does not proceed to S25 and remains as it is. The process proceeds to S26.

  Here, the process of S23-S27 is demonstrated using a specific example. First, the GUI determination unit 58 obtains a distance D (1) between the center coordinates (Gx (1), Gy (1)) of the GUI (1) and the coordinate position (X, Y) of the cursor, and this distance D ( It is determined whether or not 1) is smaller than the set distance minimum value Dmin. When the process proceeds from S22 to S23, the minimum distance value Dmin is set to a sufficiently large value as described above, and therefore the distance D (1) is determined to be smaller than the minimum distance value Dmin. , The process proceeds to S25.

  That is, the GUI determination unit 58 sets the distance D (1) to the minimum value Dmin and sets the GUI number Gno = 1 at this time in S25. Thereafter, the process proceeds to S26, where the number i = 1 assigned to the GUI is set to the number i = 2, and it is determined whether or not the number i = 2 is equal to or less than the number n of GUIs. Here, when the total number of GUIs displayed on the display unit 4 is 10, for example, the number of GUIs n = 10 is set. In this case, since the number i = 2 is smaller than the number of GUIs n = 10, the process returns to S23.

  Next, the GUI determination unit 58 obtains a distance D (2) between the center coordinates (Gx (2), Gy (2)) of the GUI (2) and the coordinate position (X, Y) of the cursor, and this distance D ( It is determined whether or not 2) is smaller than the set distance minimum value Dmin. When the GUI determining unit 58 determines that the distance D (2) is smaller than the minimum distance value Dmin (in this case, the distance D (1) is set as the minimum value Dmin), D (2) is set as the minimum value Dmin, and the GUI number Gno = 2 at this time is set.

  Thereafter, the process proceeds to S26, where the number i = 2 is changed to the number i = 3, and whether the number i = 3 is equal to or less than the number of GUIs n (in the above example, the number of GUIs n = 10). judge. In this case, since the number i = 3 is equal to or less than the number n of GUIs, the process proceeds to S23 again. If it is determined that the distance D (2) is greater than or equal to the minimum value Dmin, the process proceeds to S26 without changing the minimum value Dmin and the GUI number Gno at that time.

  That is, in the processing of S23 to S27, the GUI determining unit 58, in the above example (GUI number n = 10), from GUI (1) to GUI (10), the respective center coordinates (Gx (i), Gy (i)) and the distance D (i) between the cursor position coordinates (X, Y) are obtained. Then, the GUI determination unit 58 sets the smallest distance D (i) among the obtained distances D (i) as the minimum value Dmin, and sets the GUI number Gno at this time. Thereby, the GUI determination unit 58 can determine the GUI closest to the position coordinates of the cursor.

  When determining that the number i is larger than the number n of displayed GUIs (No in S27), the GUI determining unit 58 determines whether the GUI number Gno is larger than 0 (S28). That is, in S28, the GUI determination unit 58 determines the presence or absence of the GUI displayed on the display unit 4. If the GUI determining unit 58 determines that Gno is greater than 0, that is, if it is determined that there is a GUI displayed on the display unit 4 (Yes in S28), the cursor movement amount dX = Gx (Gno) −X, dY = Gy (Gno) -Y is obtained (S29). Then, when the GUI determination unit 58 obtains the cursor movement amount (dX, dY), it transmits the GUI number Gno to the GUI selection unit 58a.

  Here, in the GUI information storage unit 59, each GUI displayed on the display unit 4 is associated with a number i and selection permission or selection prohibition indicating whether each GUI is selectable. ing. When selection permission is associated with the GUI, the GUI determination unit 58 can perform processing so that a cursor is displayed on the GUI. On the other hand, when the GUI is associated with selection prohibition, the GUI determination unit 58, for example, this GUI is set to parental lock, linked to a restricted site, the user has no access authority, etc. Recognize that the GUI should not be selected by the user. Accordingly, in this case, the GUI determination unit 58 performs processing so that the cursor is not displayed on the GUI.

  Specifically, when receiving the GUI number Gno, the GUI selection unit 58a refers to the GUI information storage unit 59 and determines whether or not the GUI (Gno) of the GUI number Gno is a selectable GUI. (S30). That is, the GUI selection unit 58a refers to the GUI information storage unit 59 to determine whether selection is permitted for GUI (Gno) (whether selection permission is associated with GUI (Gno) or selection prohibition). Are associated with each other).

  When it is determined that the GUI (Gno) is selectable (GUI associated with selection permission) (Yes in S30), the GUI selection unit 58a transmits a selection permission signal to the GUI determination unit 58. When receiving the selection permission signal, the GUI determination unit 58 transmits the obtained cursor movement amount (dX, dY) to the cursor coordinate processing unit 56 (S31).

  When the cursor coordinate processing unit 56 obtains the position coordinate of the cursor to be moved from the received cursor movement amount (dX, dY), the cursor coordinate processing unit 56 transmits this cursor position coordinate to the display video creation unit 60 as cursor position data. Upon receiving the cursor position data, the display video creation unit 60 creates a display screen for displaying the cursor at the position indicated by the cursor position data, and transmits a display screen creation signal to the display unit 4. Thereby, the PC unit 5 can display the cursor on the display unit 4 at the position obtained by the cursor coordinate processing unit 56.

  In S31, the GUI determination unit 58 transmits the obtained cursor movement amount (dX, dY) to the cursor coordinate processing unit 56, but the present invention is not limited to this, and this cursor movement amount (dX, dY) is used. Thus, the cursor movement amount (1 + dX / 2, 1 + dY / 2) may be obtained.

  In this case, the GUI determination unit 58 transmits the cursor movement amount (1 + dX / 2, 1 + dY / 2) to the cursor coordinate processing unit 56 and then returns to the processing of S21, for example, after 100 ms. As a result, the GUI determination unit 58 can transmit the cursor movement amount (1 + dX / 2, 1 + dY / 2) to the cursor coordinate processing unit 56 at regular intervals, so that the cursor gradually approaches the target GUI. Can do.

  Here, in each of the two items of the x coordinate and the y coordinate of the cursor movement amount (1 + dX / 2, 1 + dY / 2), dX and dY are divided by 2, but if the value is larger than 1, it is particularly 2. DX and dY need not be divided by the same value. Note that the GUI determining unit 58 can adjust the speed of approaching the GUI by changing the numerical values that divide dX and dY. For example, since the cursor movement amount decreases as the numerical value that divides dX and dY increases, in this case, the GUI determination unit 58 can adjust the cursor movement speed to be slower. Further, the GUI determination unit 58 may be configured to transmit a movement amount (for example, a constant such as a movement amount 3) preset as the cursor movement amount to the cursor coordinate processing unit 56.

  On the other hand, when the GUI selection unit 58a determines that the GUI is not selectable (selection prohibited) (No in S30), the GUI selection unit 58a transmits a selection prohibition signal to the GUI determination unit 58. When receiving the selection prohibition signal, the GUI determination unit 58 determines whether or not to move the cursor from the current cursor position (S32).

If it is determined that the cursor is not moved from the current cursor position (No in S32), the GUI determination unit 58 ends the selection target GUI determination process. On the other hand, when the GUI determination unit 58 determines that the cursor is to be moved from the current cursor position (Yes in S32), the cursor movement amount (dX ₁ , dY ₁ ) = (− 10 × dX / ((dX ² + dY ^2). ) ^1/2 ), −10 × dX / ((dX ² + dY ² ) ^1/2 )) is transmitted to the cursor coordinate processing unit 56 (S33). Since the subsequent processing is the same as the processing in S31, the description thereof is omitted here.

Therefore, the PC unit 5 can display the cursor at the position coordinates of the cursor based on the cursor movement amount (dX ₁ , dY ₁ ) obtained by the GUI determination unit 58, so that the cursor can be displayed from the target GUI (Gno). Can be kept away.

In S33, the GUI determination unit 58 obtains the cursor movement amount (dX ₁ , dY ₁ ), but is not limited to this, and the cursor movement amount that can move the cursor away from the target GUI (Gno). Any cursor movement amount may be obtained as long as it is. Further, in S33, GUI determination unit 58, without obtaining the amount of movement of the cursor _(dX 1, dY _1), the cursor movement amount _{(dX 1,} dY 1) = may be (0,0).

  Note that the GUI determining unit 58 ends the selection target GUI determining process in the GUI determining unit 58 when Yes in S22, No in S28, and after the processing in S31 and S33.

  As described above, the PC unit 5 determines that the finger has moved away from the touch pad 22 by receiving twice from the remote controller 2 input data including the “movement amount 0 and key operation invalid” state. . When the PC unit 5 determines that the finger has been removed from the touch pad 22, the PC unit 5 performs selection target GUI determination processing by the GUI determination unit 58.

  Therefore, the PC unit 5 is displayed on the display unit 4 when receiving a specific signal (an input invalid signal indicating that the user's input operation has not been acquired) indicating that the finger has been removed from the touch pad 22. The cursor can be moved to the GUI located closest to the current cursor.

  Thus, when the user wants to place the cursor on an arbitrary GUI, the user simply moves the cursor to the vicinity of the GUI and then releases the finger from the touch pad 22 (that is, moves the cursor on the GUI). You don't have to). For this reason, the PC unit 5 can improve the operability of the cursor for the user. In addition, the PC unit 5 can improve the operability of the cursor particularly when the GUI is small, when operating away from the display unit 4, and the like.

  Further, when the GUI selection unit 58a determines that the GUI closest to the cursor cannot be selected, the PC unit 5 can prevent the cursor from approaching this GUI. That is, the PC unit 5 can further improve the operability of the cursor.

  Note that the GUI information storage unit 59 stores selection permission or selection prohibition indicating whether selection is possible or not in association with each GUI. However, the GUI information storage unit 59 is not limited to this and can select a selectable GUI (selection is permitted). Only the GUI that has been configured) may be stored.

Further, the GUI information storage unit 59 may previously set a distance _Dth between the cursor position coordinates and the GUI center coordinates. In this case, when determining the distance D (i), the GUI determination unit 58 reads the distance _Dth from the GUI information storage unit 59 and determines whether the distance D (i) is larger than the distance _Dth . If the GUI determining unit 58 determines that the distance D (i) is greater than the distance _Dth , the GUI determining unit 58 does not perform the selection target GUI determining process.

  Here, when the distance between the cursor and the GUI closest to the cursor is large, the user is unlikely to cause the PC unit 5 to perform processing for this GUI. Therefore, when the distance between the cursor and the GUI is greater than a predetermined distance, the PC unit 5 can be configured not to perform the process of aligning the cursor with the GUI.

  Here, regarding the selection target GUI determination processing performed by the GUI determination unit 58, the processing illustrated in FIG. 5 has been described above. However, the GUI determination unit 58 is not limited to this, and the GUI determination unit 58 may be, for example, FIG. 6A or FIG. You may perform the process using the method shown to). FIG. 6 is a diagram showing a method of searching for a GUI in order to determine a GUI that is closest to the current cursor position. FIG. 6A is far from a position near the periphery of the current cursor position. This is a method of searching for a GUI toward a position, and FIG. 5B is a diagram showing a method of searching for the nearest GUI for each divided range.

  In FIG. 6A, the GUI determination unit 58 reads out all coordinates (or center coordinates) constituting the GUI displayed from the GUI information storage unit 59 (or puts them into a readable state), and is set in advance. The position coordinates of the cursor are obtained using a calculation formula capable of moving the cursor in the arrow direction shown in FIG. The GUI determination unit 58 then displays the GUI that is closest to the cursor position before the GUI is moved when the coordinates on the GUI read from the GUI information storage unit 59 match the obtained cursor position coordinates. It is determined that

  In FIG. 6B, the GUI information storage unit 59 stores in advance range information indicating a plurality of rectangular ranges centered on the current cursor position. The GUI determination unit 58 reads out the range information indicating the smallest rectangular range together with all the coordinates (or central coordinates) constituting the GUI from the GUI information storage unit 59, so that the GUI exists in the rectangular range. Determine whether or not. If the GUI determining unit 58 determines that there is a GUI within the rectangular range, the GUI determining unit 58 determines the closest GUI by performing, for example, a selection target GUI determining process shown in FIG. On the other hand, when the GUI determining unit 58 determines that there is no GUI within the rectangular range, the GUI determining unit 58 reads range information indicating another rectangular range from the GUI information storage unit 59 and repeats the above processing. The GUI determination unit 58 sequentially reads out the range information indicating the smallest rectangular range among the plurality of rectangular ranges stored in the GUI information storage unit 59.

[Input data analysis processing in the PC according to the input operation to the touchpad (part 2)]
Next, another example of input data analysis processing in the PC unit 5 in response to an input operation on the touch pad 22 will be described. FIG. 7 is a flowchart showing the flow of another example of input data analysis processing in the PC unit 5 in response to an input operation on the touch pad 22. In the process illustrated in FIG. 7, when the PC unit 5 receives a signal indicating that the user's finger has been removed from the touch pad 22 (when a TPbreak signal is received), the PC unit 5 proceeds to the selection target GUI determination process. .

  First, when receiving some input data from the remote controller 2, the PC unit 5 starts the input data analysis process shown in FIG. When receiving the input data converted by the input data conversion unit 52, the input data analysis unit 53 analyzes what information the input data has (S41). Since the process at this time is the same as S1, detailed description thereof will be omitted.

  Here, in the remote controller 2, the input data creation unit 26 receives the movement amount detected from the movement amount detection unit 24 and the presence / absence of the click operation detected from the key operation detection unit 25, as a result of receiving from the touch pad 22. When it is determined that the finger is released, a TPbreak signal indicating that the finger is released from the touch pad 22 is generated. Then, the input data creation unit 26 transmits the input data including this TPbreak signal to the PC unit 5 via the transmission unit 21. That is, the input data analysis unit 53 extracts the movement amount data and the key operation valid / invalid state from the received input data, or extracts the TPbreak signal when the TPbreak signal is included.

  Then, the input data analysis unit 53 transmits the analysis result, that is, the movement amount data and key operation information extracted from the input data, or the TPbreak signal to the input data determination unit 54 as analysis data.

  When receiving the analysis data from the input data analysis unit 53, the input data determination unit 54 determines whether or not the analysis data indicates the TPbreak signal (S42). When the input data determination unit 54 determines that the analysis data indicates the TPbreak signal (Yes in S42), the input data determination unit 54 determines that the finger is released from the touch pad 22, and sets a preset time (here, 0.5 seconds). It is determined whether or not there is an input operation to the touch pad 22 (S43). That is, the input data determination unit 54 determines whether or not to receive analysis data that does not indicate a TPbreak signal within a preset time.

  When it is determined that there is no input operation to the touch pad 22 within a preset time, that is, when the analysis data that does not indicate the TPbreak signal is not received within this time (Yes in S43). ), And transmits a GUI determination signal to the GUI determination unit 58. And the GUI determination part 58 will perform the selection object GUI determination process mentioned above, if a GUI determination signal is received (S44).

  On the other hand, when it is determined that the input operation to the touch pad 22 has been performed within a preset time, that is, the input data determination unit 54 determines that it has received analysis data that does not indicate the TPbreak signal (No in S43). , The process returns to S41.

  Next, when the input data determination unit 54 determines that the analysis data does not indicate the TPbreak signal (Yes in S42), “the movement amount is 0 and the key operation is invalid (that is, there is no movement operation and no selection operation). It is determined whether or not the analysis data indicates a state. When the input data determination unit 54 determines that the analysis data indicates the “movement amount 0 and key operation invalid” state (Yes in S45), the input data analysis process ends.

  On the other hand, when the input data determination unit 54 determines that the analysis data does not indicate the “movement amount 0 and key operation invalid” state (No in S45), “there is a movement amount and key operation is invalid (ie, there is a movement operation, In addition, it is determined whether or not the analysis data indicates a state of “no selection operation” (S46). In addition, since the process after this, ie, the process of S46-S51, is the same as the process of S8-S13 shown in FIG. 4, the description is abbreviate | omitted here.

  As described above, the PC unit 5 receives the input data including the TPbreak signal instead of the input data including the “movement amount 0 and key operation invalid” state from the remote controller 2. Judged to be away. When the PC unit 5 determines that the finger has been removed from the touch pad 22, the PC unit 5 performs selection target GUI determination processing by the GUI determination unit 58.

  Therefore, the PC unit 5 is displayed on the display unit 4 when receiving a specific signal (an input invalid signal indicating that the user's input operation has not been acquired) indicating that the finger has been removed from the touch pad 22. The cursor can be moved to the GUI closest to the cursor.

  Thus, when the user wants to place the cursor on an arbitrary GUI, the user simply moves the cursor to the vicinity of the GUI and then releases the finger from the touch pad 22 (that is, moves the cursor on the GUI). You don't have to). For this reason, the PC unit 5 can improve the operability of the cursor for the user.

[Phenomenon diagram when input data analysis processing is performed]
Next, the state of the remote controller 2 and the display unit 4 when the input data analysis process described above is performed in the PC unit 5 will be described. FIG. 8 is a phenomenon diagram showing the state of the remote controller 2 and the display unit 4 when the input data analysis processing in the PC unit 5 is performed. In FIG. 8, the GUI 41a and the GUI 41b are displayed on the display unit 4, but here the user intends to place the cursor on the GUI 41a (here, the GUI 41a is a selectable GUI). It shall be. In FIG. 8, the PC unit 5 is not shown.

  First, the user can move the cursor by placing a finger on the touch pad 22 provided in the remote controller 2 and moving it. That is, when the user puts his / her finger on the touch pad 22 and moves it, input data including movement amount data and key operation information created by the input data creation unit 26 of the remote control 2 is transmitted from the remote control 2 to the PC unit 5. Is done. At this time, the remote controller 2 transmits input data including information indicating the “movement amount (x, y) and key operation invalid” state to the PC unit 5. Note that the movement amount (x, y) at this time is a value other than the movement amount (0, 0).

  The PC unit 5 can display the cursor at the position indicated by the position coordinate of the cursor by analyzing the received input data and obtaining the position coordinate of the cursor. For this reason, the display unit 4 displays the movement of the cursor in conjunction with the movement of the finger touching the touch pad 22. Note that the movement of the cursor at this time is only required to be close to the GUI 41a, and the cursor does not have to be moved onto the GUI 41a. That is, the user only needs to move the cursor roughly to the vicinity of the GUI 41a.

  Next, when the user moves the cursor to the vicinity of the GUI 41a, the user releases the finger from the touch pad 22. At this time, the remote controller 2 transmits the input data including the information indicating the “movement amount 0 and key operation invalid” state twice in succession to the PC unit 5 or transmits the TPbreak signal to the PC unit 5. The PC unit 5 determines that the finger has been released from the touch pad 22 when receiving input data including information indicating the “movement amount 0 and key operation invalid” state twice in succession or when receiving the TPbreak signal.

  At this time, in the PC unit 5, the GUI determination unit 58 determines the GUI closest to the current cursor position, and obtains the cursor movement amount (dX, dY) for moving the cursor to this GUI. Thereby, the PC unit 5 can display the cursor on the GUI 41a. That is, the PC unit 5 can move the cursor on the GUI 41a from the position of the cursor displayed when the finger is released from the touch pad 22.

  Thereafter, when the user desires to click on the GUI 41a, the user presses the click key 23 to cause the PC unit 5 to perform processing associated with the GUI 41a and to display the state on the display unit 4. be able to.

[Embodiment 2]
Another embodiment of the present invention will be described below with reference to FIGS. In addition, about the member which has the same function as Embodiment 1, the same code | symbol is attached and the description is abbreviate | omitted. FIG. 9 is a block diagram showing another schematic configuration of the remote controller 2 and the PC unit 5 in the transmission / reception system 1 of the present invention.

  When receiving data from the remote controller 2, the PC unit 5 according to the first embodiment receives the input data including “movement amount 0 and key operation invalid” twice in succession from the remote controller 2, or receives a TPbreak signal. When input data including the input data is received, the process proceeds to selection target GUI determination processing. In other words, the PC unit 5 according to the first embodiment is configured to shift to the selection target GUI determination process when it is determined that the finger is separated from the touch pad 22.

  On the other hand, when receiving data from the mouse 3, the PC unit 5 according to the present embodiment performs selection target GUI determination processing. The PC unit 5 according to the present embodiment does not include the receiving unit 51 of the PC unit 5 shown in FIG. 1 of the first embodiment, and the input data converting unit 52 receives input data from the mouse 3. Other configurations are the same as the configuration of the PC unit 5 shown in FIG. 1 of the first embodiment.

  The mouse 3 includes a ball 32, a click key 33, a movement amount detection unit 34, a key operation detection unit 35, and an input data creation unit (acquisition determination unit, input invalid signal creation unit) 36. Note that the click key 33 and the key operation detection unit 35 have the same functions as the click key 23 and the key operation detection unit 25 of the remote controller 2, and thus the description thereof is omitted here.

  The ball 32 is a rotating member that can be rotated in accordance with the moving direction of the mouse 3, and the amount and direction of rotation of the ball 32 are detected by the moving amount detection unit 34.

  When the movement amount detection unit 34 detects the rotation amount and the rotation direction of the ball 32, the movement amount detection unit 34 obtains the movement amount from the rotation amount and the rotation direction. Then, the movement amount detection unit 34 transmits the obtained movement amount to the input data creation unit 36 as movement amount data.

  Note that the mouse 3 may include an optical sensor instead of the ball 32. In this case, the optical sensor acquires the unevenness of the ground contact surface on which the mouse 3 is operated, and transmits information indicating the acquired unevenness to the movement amount detection unit 34. The movement amount detection unit 34 extracts a change in information indicating the unevenness, and calculates a movement amount using the extraction result.

  The input data creation unit 36 creates input data for input to the PC unit 5 from the movement amount data received from the movement amount detection unit 34 and the key operation information received from the key operation detection unit 35. Then, the input data creation unit 36 transmits this input data to the input data conversion unit 52 of the PC unit 5.

[Input data analysis processing in the PC according to mouse input operations]
Next, input data analysis processing in the PC unit 5 according to an input operation to the mouse 3 will be described. FIG. 10 is a flowchart showing the flow of input data analysis processing in the PC unit 5 in response to an input operation to the mouse 3. In the process illustrated in FIG. 10, when the PC unit 5 determines that the input operation to the mouse 3 has not been performed for a predetermined time, the PC unit 5 proceeds to a selection target GUI determination process.

  First, when receiving some input data from the mouse 3, the PC unit 5 starts an input data analysis process shown in FIG. When the input data converted by the input data converter 52 is received, the input data analyzer 53 analyzes what information the input data has (S61). Since the process at this time is the same as S1, detailed description thereof will be omitted.

  Next, the input data analysis unit 53 transmits the analysis result, that is, the movement amount data extracted from the input data and the key operation information to the input data determination unit 54 as analysis data. The input data determination unit 54 determines whether or not the analysis data is analysis data indicating a state of “movement amount 0 and key operation invalid (that is, no movement operation and no selection operation)” (S62). The subsequent processing, that is, the processing of S62 to S68, in the case of Yes in S62, and the processing other than after the processing of S64, S66, and S68 are the same as the processing of S45 to S51 shown in FIG. Then, the explanation is omitted. In the input data analysis process shown in FIG. 10, the process returns to S61 after S66 and S68.

  When the input data determination unit 54 determines that the analysis data indicates the “movement amount 0 and key operation invalid” state (Yes in S62), or after the processing of S64 by the cursor coordinate processing unit 56, the timer 55 starts timing. A signal is transmitted and the timer 55 is activated. Then, the input data determination unit 54 determines whether or not there is an input operation to the mouse 3 within a time preset in the timer 55 (here, 1 second) (S69).

  When the input data determination unit 54 determines that there is no input operation to the mouse 3 within a time set in advance in the timer 55, that is, indicates a state in which “the movement amount is 0 and the key operation is not invalid” within a predetermined time. If it is determined that the analysis data has not been received (Yes in S69), a GUI determination signal is transmitted to the GUI determination unit 58. When receiving the GUI determination signal, the GUI determination unit 58 performs the selection target GUI determination process described above (S70). The time set in advance in the timer 55 may be any time as long as it can be determined by the PC unit 5 that the input operation to the mouse 3 has been completed, and may be set in any manner.

  On the other hand, when it is determined that the input operation to the mouse 3 has been performed within a preset time, the input data determination unit 54 has received analysis data indicating that the movement amount is 0 and the key operation is not invalid. If determined (No in S69), the process returns to S61.

  As described above, when the PC unit 5 determines that a predetermined time has elapsed since the input data including the “movement amount 0 and key operation invalid” state is received from the mouse 3, the input operation to the mouse 3 is performed. Judge that there is no. That is, when the PC unit 5 determines that a predetermined time has elapsed since receiving input data including the “movement amount 0 and key operation invalid” state, an input indicating that the user's input operation has not been acquired. It is determined that an invalid signal has been received.

  Therefore, when the PC unit 5 determines that a predetermined time has elapsed after receiving the input data including the “movement amount 0 and key operation invalid” state, the position closest to the cursor displayed on the display unit 4 You can move the cursor to the GUI at

  Thus, when the user wants to place the cursor on an arbitrary GUI, the user simply moves the cursor to the vicinity of the GUI and then releases the hand from the mouse 3 (that is, moves the cursor on the GUI). Not necessary). For this reason, the PC unit 5 can improve the operability of the cursor for the user.
