Description

  The present invention relates to an information processing apparatus including a touch pad.

  In recent information processing devices such as portable game devices, a configuration in which a touch panel for input operation is provided at a position different from the display surface of the device has been proposed for the purpose of improving the visibility of the display surface. For example, Patent Document 1 discloses a configuration in which a touch panel is provided on the back side of the display surface of a game device (a back-side input device configuration).

  In the apparatus of Patent Literature 1, a touch panel installed on the back surface of the display surface is touched for a predetermined time or longer, whereby a cursor is displayed on the display surface, and the cursor on the display surface moves as the finger moves on the touch panel. . Then, after the cursor has moved to the object, the position where the finger is released from the touch panel becomes the input temporary determination position. Next, when a tap operation is performed on the touch panel after a predetermined time or more has elapsed after the input position provisional determination by the cursor, the input determination operation on the display surface is performed at a position corresponding to the touch coordinates of the touch panel. As described above, the apparatus disclosed in Patent Document 1 aims to suppress erroneous input in the rear surface input operation by making the user visually recognize the position of the cursor.

Embodiment 1
Embodiment 1 of the present invention will be described below with reference to FIGS. As shown below, the cellular phone 1 (information processing apparatus) of the present embodiment is configured to suppress erroneous input in the “pointer mode” operation mode.

(Outline of mobile phone)
A mobile phone according to the present embodiment will be described with reference to FIG. FIG. 2 is a diagram illustrating an appearance of the mobile phone 1 according to the present embodiment. As shown in FIG. 2, the mobile phone 1 is a so-called foldable mobile phone. The first housing 81 and the second housing 82 are connected via a hinge 83 and are rotatable about the axis of the hinge 83. The 1st housing | casing 81 and the 2nd housing | casing 82 are substantially flat shape, for example. The display unit 70 is disposed on one surface of the first housing 81. A hard key 85 is disposed on one surface of the second casing 82, and is placed under the hard key 85 (inside the second casing 82) so as to be superimposed on the hard key 85 for the touch pad 80 (object detection unit). Sensors are arranged.

  The cellular phone 1 has an open state (the form shown in FIG. 2) in which the first housing 81 and the second housing 82 are opened, and a surface (display surface) on which the display unit 70 of the first housing 81 is disposed. And a closed state (not shown) in which the surface (operation surface) on which the hard key 85 of the second housing 82 is disposed is opposed.

  The display unit 70 displays an image. As the display unit 70, for example, an LCD (liquid crystal display), an organic EL display, or the like can be applied. The hard key 85 is for the user to operate the mobile phone 1. The hard key 85 is a physical key that outputs a signal corresponding to the key pressed by the user. For example, the hard key 85 is a menu key, numeric keypad, cross key, center key, on-hook key, off-hook key, or the like.

  The touch pad 80 is for operating the mobile phone 1. The touch pad 80 includes the sensor, detects an object (such as a user's finger or stylus) that approaches or touches the touch pad 80 at predetermined time intervals, and detects the detected position (for example, two-dimensional on the touch pad 80). Position information indicating coordinates) is output. The detection area where the touch pad 80 detects an object is the entire surface (operation surface) on which the hard key 85 of the second housing 82 is disposed. That is, the operation surface of the second housing 82 is the detection surface of the touch pad 80. Therefore, the key top surface of the hard key 85 is a part of the detection surface and is included in the detection region. The sensor provided in the touch pad 80 is a capacitance sensor or the like.

  In the present embodiment, the touch pad 80 detects whether the user's finger is in contact with the operation surface of the second housing 82. As shown in FIG. 2, the operation surface (detection region of the touch pad 80) of the second housing 82 is at a position different from the display surface (display region) of the display unit 70.

  In addition, although the foldable mobile phone 1 is shown in FIG. 2, the present invention is not limited to this, and a mobile phone of straight type, slide type, biaxial hinge type, or the like may be used. In the present embodiment, a mobile phone is illustrated, but the present invention is not limited to this. The present invention is applied to an arbitrary information processing apparatus comprising: a display unit; and an object detection unit having a planar detection area for detecting an object approaching or touching at a position different from the display area of the display unit. Is possible. The present invention is applicable to, for example, notebook PCs, portable game machines, digital cameras, digital video cameras, portable music players, and the like.

(Mobile phone operation system)
As described above, the mobile phone 1 has the two operation units (input units) of the hard key 85 and the touch pad 80. In order to facilitate the user's operation with the touch pad 80 (to prevent erroneous operation), the mobile phone 1 has three modes of “key operation mode”, “pointer mode”, and “scroll mode”.

  The key operation mode is a mode that can be operated only with the hard key 85. That is, in the key operation mode, the operation using the touch pad 80 is invalid. In key operation mode, for example, operate the cross key to move the focus (select an item in the list), press the center key to make a decision, operate the numeric keypad to enter numbers or characters, or go off-hook. A call can be started by pressing a key, or a call or application can be ended by pressing an on / off hook key.

  When the off-hook key is pressed and held in the key operation mode, the mode is shifted to the pointer mode. In the key operation mode, a specific application is activated to shift to the pointer mode. Note that the key operation mode is set when the cellular phone 1 is activated.

  The pointer mode is a mode in which a cursor with an arrow mark is displayed on the screen, and a cursor moving operation and a determining operation using the touch pad 80 are enabled. The pointer mode includes a cursor non-display state and a cursor display state. In the cursor non-display state, the user touches the touch pad 80 (the operation surface of the second housing 82) and swipes a little to display the cursor. That is, the cursor transitions to the cursor display state. Moreover, the operation by the hard key 85 is possible similarly to the key operation mode. In the cursor display state, the user can move the cursor by swiping or flicking the touch pad 80, or single-tap the touch pad 80 within a predetermined time (for example, 1.5 seconds) after the cursor moves. Thus, the determination can be input at the position where the cursor is present, or the determination can be input at the position where the cursor is present by double-tapping the touch pad 80. When the hard key 85 is pressed in the cursor display state, the cursor is deleted. That is, the state transits to a cursor non-display state. Also, when a predetermined time elapses without operating the touch pad 80 in the cursor display state, the cursor transitions to the cursor non-display state. In the pointer mode, operation by the hard key 85 is possible as in the key operation mode.

  In the pointer mode, the key operation mode is entered by long-pressing the off-hook key. Also, the key operation mode is entered by terminating the specific application. In the pointer mode, a long tap on the touch pad 80 shifts to the scroll mode. When the mode is changed to the pointer mode, the cursor is displayed.

  The scroll mode is a mode that enables the screen to be scrolled by the touch pad 80. In the scroll mode, the screen can be scrolled by swiping or flicking the touch pad 80, or a predetermined process corresponding to the running application can be executed by long-tapping the touch pad 80. In the scroll mode, a single tap on the touch pad 80 shifts to the pointer mode. Also, in the scroll mode, when the predetermined time has passed without operating the touch pad 80, the mode is shifted to the pointer mode. In the scroll mode, when the specific application is finished, the key operation mode is entered.

  FIG. 1 is a block diagram illustrating a configuration of a main part of the mobile phone 1. As shown in FIG. 1, the mobile phone 1 includes a main control unit 10 and a storage unit 90 in addition to the above-described members. For simplification of explanation, illustration of some members in FIG. 2 is omitted. Hereinafter, the operation of each member in the pointer mode will be described in detail.

  The main control unit 10 comprehensively controls the operation of the mobile phone 1. The function of the main control unit 10 is realized by a CPU (Central Processing Unit) executing a program stored in the storage unit 90. The storage unit 90 is a storage device that stores various programs executed by the main control unit 10 and data used by the programs.

  The main control unit 10 includes a display control unit 20 and a touch pad control unit 30. The display control unit 20 controls the operation of the display unit 70 and causes the display unit 70 to display various images. The display control unit 20 includes a cursor display unit 21, an icon display unit 22, and a cursor display change unit 23. The cursor display changing unit 23 will be described in a third embodiment to be described later.

  The touch pad control unit 30 controls the operation of the touch pad 80, acquires position information from the touch pad 80, and performs various processes. The touch pad control unit 30 includes a detection unit 31 (position information acquisition unit) and an event processing unit 32. The event processing unit 32 includes an analysis unit 33, a time determination unit 34 (input determination unit), a distance determination unit 35 (input determination unit), and a mode transition unit 36 (input determination unit). In addition, about the distance determination part 35 and the mode transition part 36, the below-mentioned Embodiment 2 and 4 are described, respectively.

  Hereinafter, a description will be given with reference to FIGS. FIGS. 3E to 3H are diagrams illustrating the flow of the user's operation on the operation surface. FIGS. 3A to 3D are views of the screen on the display surface corresponding to the operation. It is a figure which illustrates change. The detection unit 31 acquires position information from the touch pad 80 to detect each of touchdown and touchup. The touchdown is an operation in which the user brings the finger F into contact with the touch pad 80 ((e) in FIG. 3). Touch up is an operation in which the user releases the finger F from the touch pad 80.

  When detecting the touchdown, the detection unit 31 provides the cursor display unit 21 with position information indicating the position of the finger F on the touch pad 80 (contact position Pt), and causes the storage unit 90 to store the contact position Pt. And the cursor display part 21 displays the cursor C in the position of the display part 70 corresponding to the contact position Pt ((a) of FIG. 3). The cursor C is an icon serving as an index of the operation position on the display unit 70, and is displayed as an arrow mark, for example. The position on the display unit 70 (the coordinate system of the display surface) and the position on the touch pad 80 (the coordinate system of the detection surface) are associated with each other in advance in a one-to-one relationship.

  Moreover, the detection part 31 produces | generates a touch event based on the temporal change of a positional information, after detecting a touchdown or a touchup. The touch event is information indicating the type of touch (touch down, touch up, move, etc.) associated with each user operation. The touch event may include information such as a vector indicating the moving direction and speed of the contact position.

  The analysis unit 33 acquires a touch event from the detection unit 31, and detects a user operation (move operation, tap operation, etc.) corresponding to the touch event. The user operation detected by the analysis unit 33 may be used as a trigger for executing various processes (for example, execution of an application) in the main control unit 10. Note that the analysis unit 33 can also use the touch event itself detected by the detection unit 31 as a trigger for executing various types of processing (for example, icon display) in the main control unit 10.

  First, the move operation will be described. The move operation is an operation of moving the finger F while making contact with the touch pad 80 ((f) in FIG. 3). As an example, the analysis unit 33 detects a move operation when the touchdown state continues for a predetermined time or more. In this case, the cursor display unit 21 changes the position of the cursor C so as to correspond to the temporal change in the position information and displays it on the display unit 70 ((b) in FIG. 3). Thereby, the user can move the cursor C onto the button B (object) displayed on the display unit 70 while visually recognizing the display unit 70.

  The analysis unit 33 determines that the move operation has been completed when the detection unit 31 detects a touch-up during the move operation. The detection unit 31 stores the time when the touch-up is detected (in other words, the time when the close state of the object or the release of the contact state is detected; hereinafter referred to as the touch release time T) as the touch release time 92. Stored in the unit 90. In addition, the cursor display unit 21 stores the position of the cursor C at the touch release time T (cursor position Pc) in the storage unit 90 as the cursor position 91.

  Next, the tap operation will be described. The tap operation is an operation for quickly touching up immediately after touchdown ((g) in FIG. 3). As an example, when the move operation is not detected and the detection unit 31 detects a touch-up, the analysis unit 33 determines the position (contact release position Pr) on the touch pad 80 where the finger F is separated from the detection unit 31. get. And the analysis part 33 detects tap operation, when the distance of the contact position Pt and the contact cancellation | release position Pr is below a predetermined threshold value. In the present embodiment, a time determination unit 34 shown below is provided in order to suppress erroneous input during a tap operation. The tap operation is used as a trigger for causing the time determination unit 34 to perform predetermined processing (for example, input processing to the button B) to the cursor position Pc.

  The time determination unit 34 determines whether a specific touch event (a touch event indicating a tap operation) has occurred within a predetermined time (for example, within 1.5 seconds) from the touch release time T. In other words, it may be understood that the time determination unit 34 determines whether or not a tap operation has been performed within a predetermined time from the touch release time T. Note that the predetermined time from the touch release time T may be referred to as a tap effective time.

  When a specific touch event occurs, the time determination unit 34 moves to the cursor position Pc corresponding to the specific touch event when the specific touch event occurs within a predetermined time from the touch release time T. Is effective ((c) of FIG. 3). Thereby, after the tap operation ((h) in FIG. 3), the input process at the cursor position Pc is accepted ((d) in FIG. 3).

  Next, a case where another determination result is shown in the time determination unit 34 will be described with reference to FIGS. FIGS. 4A to 4H correspond to FIGS. 3A to 3H described above, and FIGS. 4A to 4H are the same as FIGS. Since (h) and (h) are the same as those in FIG.

  FIG. 4G illustrates a case where a tap operation is performed after a predetermined time has elapsed from the touch release time T. In this case, the time determination unit 34 determines that the occurrence of the specific touch event is not within a predetermined time from the touch release time T, and invalidates the input operation corresponding to the tap operation ((c in FIG. 4). )). For this reason, although the tap operation is performed, the input operation for the button B is not accepted ((d) in FIG. 4).

  The icon display unit 22 operates based on the determination result acquired from the time determination unit 34. When the tap operation is performed within the tap effective time from the touch release time T, the icon display unit 22 displays an icon I indicating that the input process corresponding to the tap operation is valid at the cursor position Pc. ((C) of FIG. 3). The icon I may be a ripple mark, for example. On the other hand, when the tap operation is performed after the tap effective time has elapsed from the touch release time T, the icon I is not displayed ((c) of FIG. 4). This allows the user to visually recognize that the tap operation as a trigger for the input operation to the cursor position Pc has been appropriately performed.

(User operation determination process flow)
FIG. 5 is a flowchart illustrating processing S1 to S9 for determining user operations. The detector 31 initializes the touch release time T (S1), and then detects a touchdown (S2). Then, the analysis unit 33 determines whether a move operation is performed (S3).

  When the analysis unit 33 detects a move operation (YES in S3), the cursor display unit 21 moves the position of the cursor C on the display unit 70 in response to the move operation (S4, cursor display step). And analysis part 33 judges with a move operation having been completed, when touch-up is detected in detection part 31 (S5). The detection unit 31 stores the touch release time T in the storage unit 90, and the cursor display unit 21 stores the cursor position Pc in the storage unit 90 (S6). And it returns to process S2 and repeats the same process.

  On the other hand, if the moving operation is not detected (NO in S3), the analyzing unit 33 determines whether or not a touch-up is detected in the detecting unit 31 (S7), and determines the presence or absence of the tap operation. When the analysis unit 33 detects a tap operation (YES in S7), the time determination unit 34 determines whether or not a specific touch event has occurred within the tap effective time (predetermined time) from the touch release time T. Determine (S8). When a specific touch event occurs within the tap effective time from touch release time T (YES in S8), time determination unit 34 accepts a process corresponding to the tap operation at cursor position Pc (S9, input determination step) ).

  On the other hand, when the detection unit 31 does not detect the tap operation (NO in S7), the process returns to the process S3. If a specific touch event has not occurred within the tap effective time from the touch release time T (NO in step S8), the process returns to step S1.

  As described above, according to the mobile phone 1 of the present embodiment, after the move operation is completed, the user operation (tap operation) corresponding to the specific touch event is not performed after the tap effective time elapses from the touch release time T. In the case of a failure, the process (input process) corresponding to the tap operation at the cursor position Pc is not accepted. That is, when a tap operation is performed after the tap time has elapsed, the above-described input operation becomes invalid. Therefore, it is possible to more effectively suppress an erroneous input due to a tap operation that the user does not intend than before.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIG. 1 and FIGS. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted. In the present embodiment, the operation of the distance determination unit 35 will be described. The distance determination unit 35 is a member provided to more effectively suppress erroneous input during a tap operation.

  Hereinafter, a description will be given with reference to (a) to (h) of FIG. FIGS. 6A to 6H correspond to FIGS. 4A to 4H described above, and FIGS. 6A to 6D, 6E, and 6H. Since is substantially the same as FIG. 4, the description thereof is omitted. In the present embodiment, the detection unit 31 detects the position (touch release position P) on the touch pad 80 where the finger F is released when the move operation is completed ((f) in FIG. 6). Then, the detection unit 31 stores the touch release position P in the storage unit 90 as the touch release position 93.

  The distance determination unit 35 acquires, from the analysis unit 33, the position on the touch pad 80 where the tap operation is performed after the analysis unit 33 detects the tap operation. Specifically, the distance determination unit 35 acquires the above-described contact release position Pr as the position where the tap operation has been performed. Then, the distance determination unit 35 determines whether or not the position where the tap operation is performed (that is, the contact release position Pr) is within a predetermined distance range from the touch release position P ((g in FIG. 6). )). FIG. 6G shows a predetermined distance r. Note that the value of the distance r may be appropriately set by the manufacturer of the mobile phone 1 according to the size of the touch pad 80 or the like.

  The distance determination unit 35 operates the time determination unit 34 when the position where the tap operation is performed is within the range of the distance r from the touch release position P. In this case, if a specific touch event occurs within the tap effective time from the touch release time T, the input process to the button B becomes valid at the cursor position Pc.

  On the other hand, the distance determination unit 35 does not operate the time determination unit 34 when the position where the tap operation is performed does not exist within the distance r from the touch release position P. In this case, even if a touch event occurs within the tap effective time from the touch release time T, the input process to the button B becomes invalid at the cursor position Pc.

(Processing flow of user operation determination in this embodiment)
FIG. 7 is a flowchart illustrating user operation determination processes S11 to S21 in the present embodiment. The processes S11, S13 to S16, S18, and S20 to S21 in FIG. 7 are the same as the processes S1, S2 to S5, S7, and S8 to S9 in FIG. To do. Here, only the processing S12, the processing S17, the processing S19 and their peripheral processing will be described.

  Subsequent to the process S11, the detection unit 31 initializes the touch release time P (S12). And it progresses to process S13. Subsequently, following the process S16, the detection unit 31 stores the touch release time T and the touch release position P in the storage unit 90, and the cursor display unit 21 stores the cursor position Pc in the storage unit 90 (S17). ). And it returns to process S13.

  Then, following the process S18, the distance determination unit 35 determines whether or not the position where the tap operation has been performed is within a predetermined distance r from the touch release position P (process S19). When the position where the tap operation is performed is within the range of the distance r from the touch release position P (YES in process S19), the process proceeds to process S20. On the other hand, when the position where the tap operation is performed does not exist within the range of the distance r from the touch release position P (NO in process S19), the process returns to process S11.

  By the way, when the user touches the touch pad 80 unintentionally, a situation is assumed in which the position where the tap operation is performed is located relatively far from the touch release position P. Therefore, by providing the distance determination unit 35, when the position where the tap operation is performed does not exist in the vicinity of the touch release position P after the move operation is completed, the distance determination unit 35 depends on the occurrence timing of a specific touch event. Therefore, it is possible to invalidate the process corresponding to the tap operation. Therefore, erroneous input due to a tap operation can be more effectively suppressed.

[Embodiment 3]
The following will describe another embodiment of the present invention with reference to FIGS. 1 and 8 to 9. In the present embodiment, the operation of the cursor display changing unit 23 will be described. The cursor display changing unit 23 can allow the user to visually recognize that a tap operation as a trigger for input processing is acceptable.

  Hereinafter, a description will be given with reference to (a) to (f) of FIG. FIGS. 8A to 8F correspond to FIGS. 4A to 4H described above, and FIGS. 8A and 8D are respectively the same as FIG. 4B. And (f).

  In the present embodiment, after the detection unit 31 stores the touch release time T in the storage unit 90 ((e) in FIG. 8), the cursor display change unit 23 extends from the touch release time T within the tap effective time, The figure (shape, display) of the cursor C is changed ((b) of FIG. 8). As an example, the cursor display changing unit 23 may change the arrow-shaped cursor C to a star-shaped icon I2 and display it. Then, after the tap effective time has elapsed from the touch release time T ((f) in FIG. 8), the cursor display changing unit 23 returns the display of the icon I2 to the cursor C ((c) in FIG. 8). As described above, the cursor display changing unit 23 changes the graphic of the cursor C between the tap effective time and the tap effective time.

  However, the cursor display changing unit 23 is not limited to the one that changes the figure of the cursor C, and may be any one that changes the display form of the cursor C. For example, the cursor display changing unit 23 may change the time interval at which the cursor C blinks between the tap effective time and the elapse of the tap effective time.

(Processing flow of user operation determination in this embodiment)
FIG. 9 is a flowchart illustrating user operation determination processes S31 to S30 in the present embodiment. Note that the processes S31 to S36 and S38 to S40 in FIG. 9 are the same as the processes S1 to S6 and S7 to S9 in FIG. Here, only the process S37 and its peripheral processes will be described.

  Subsequent to the process S36, the cursor display changing unit 23 changes the display of the cursor C from the touch release time T to the tap effective time (process S37). And it returns to process S32. As described above, the provision of the cursor display changing unit 23 allows the user to visually recognize that the tap operation as the trigger for the input process is acceptable only during the period in which the shape of the cursor C is changed. Can be recognized. Therefore, erroneous input due to a tap operation can be more effectively suppressed.

  The cursor display changing unit 23 may delete the cursor C after the tap effective time has elapsed. In this case, only when the cursor C is displayed, the user can recognize that the tap operation can be accepted.

  In this case, the process S34 may be understood to include a process of “switching the presence / absence of cursor display”. Further, the process S37 may be understood to include a process of “displaying the cursor C as a tap operation valid state for a predetermined time from T”.

[Embodiment 4]
The following will describe another embodiment of the present invention with reference to FIGS. 1 and 10 to 11. In the present embodiment, the operation of the mode transition unit 36 will be described. The mode transition unit 36 is a member provided assuming various use cases of the mobile phone 1.

  Hereinafter, a description will be given with reference to FIGS. 10A to 10H correspond to FIGS. 6A to 6H described above, and FIGS. 10A to 10C and FIG. It is the same.

  In the present embodiment, when the time determination unit 34 determines that a specific touch event has occurred within the tap effective time from the touch release time T ((f) in FIG. 10), the mode transition unit 36 selects the specific touch event. It is determined whether or not a touch event (touch event indicating a touch operation) different from the specific touch event has occurred within a predetermined time (for example, within 0.5 seconds) from the occurrence of (see FIG. 10). (G)). In other words, it may be understood that the mode transition unit 36 determines whether or not the detection unit 31 detects a touchdown within a predetermined time from the occurrence of a specific touch event. Note that the predetermined time from the occurrence of a specific touch event may be referred to as a touch effective time.

  When the mode transition unit 36 detects that another touch event has occurred within the touch effective time from the occurrence of the specific touch event, the mode transition unit 36 invalidates the process corresponding to the specific touch event. And the mode transition part 36 validates the process (drag process) which moves the button B according to a move operation as a process corresponding to another touch event. That is, the mode transition unit 36 transitions the operation mode of the mobile phone 1 to a drag mode that accepts a process of moving the button B in response to the move operation ((d) and (h) in FIG. 10).

  On the other hand, when the mode transition unit 36 does not detect that another touch event has occurred within the touch effective time from the occurrence of the specific touch event, the mode transition unit 36 does not invalidate the processing corresponding to the specific touch event, and enters the drag mode. Do not make a transition. In the mode transition unit 36, the process corresponding to the other touch event is not limited to the transition to the drag mode. The process may be any process different from the process corresponding to the specific touch event described above.

(Processing flow of user operation determination in this embodiment)
FIG. 11 is a flowchart illustrating user operation determination processing S51 to S60 according to the present embodiment. Note that the processes S51 to S58 and S61 in FIG. 11 are the same as the processes S1 to S8 and S9 in FIG. Here, only the processes S59 to S60 and their peripheral processes will be described.

  Subsequent to step S58, the mode transition unit 36 determines whether another touch event has occurred within the touch effective time from the occurrence of the specific touch event (step S59). When another touch event occurs within the touch effective time from the occurrence of the specific touch event (YES in S59), the mode transition unit 36 performs transition to the drag mode (process S60). On the other hand, when another touch event occurs within the touch effective time from the occurrence of the specific touch event, the process proceeds to step S61.

  Here, in the mobile phone 1, a case where the button “B” is a folder is taken as an example, and a case where a process “open folder” is assigned as a process corresponding to a specific touch event is considered. In the present embodiment, when another touch event occurs within the touch effective time after the occurrence of the specific touch event, the “open folder” process is invalidated and the transition to the drag mode is performed. In other words, the tap operation can be used as a trigger for performing the transition to the drag mode. Thus, by providing the mode transition unit 36, it is possible to deal with more various use cases of the mobile phone 1.
