<Overview>
FIG. 3 is a diagram for explaining an example of remote operation of the display using the touch pad by the remote control device of the present embodiment. As shown in this figure, the display α targeted for remote operation by the remote control device of this embodiment has a screen aspect ratio of “9:16”. On the other hand, the aspect ratio of the touch pad β provided in the remote control device of this embodiment is “3: 4”. Thus, when the aspect ratios of the two are different, the remote control device of the present embodiment is characterized by performing the following processing.

  That is, the remote control device acquires aspect ratio information of the display screen using bidirectional communication such as IrSimple. Then, in accordance with the acquired aspect ratio information, the area on the touchpad indicated by the oblique lines in the figure is set as the non-operational area.

<Functional configuration>
FIG. 4 is a diagram illustrating an example of functional blocks in the remote control device according to the present embodiment. As shown in this figure, the “remote control device” (0400) of this embodiment includes a “communication unit” (0401), a “touchpad unit” (0402), and an “aspect ratio information acquisition unit” (0403). , An “operational expression storage unit” (0404), an “operation disabled area calculation unit” (0405), and an “operation disabled setting unit” (0406).

  Note that functional blocks such as the remote control device and the display device described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a bus, or a secondary storage device (a hard disk, a non-volatile memory, a storage medium such as a CD or a DVD, a read drive for the medium, etc.), information Input devices used for input, printing equipment, display devices, other hardware components such as external peripheral devices, interfaces for external peripheral devices, communication interfaces, driver programs for controlling these hardware, Other examples include application programs and user interface applications.

  Then, through the arithmetic processing of the CPU according to the program developed on the main memory, the data input from the input device or other interface etc. and stored in the memory or hard disk is processed and stored, or each of the above hardware and software An instruction for controlling the above is generated. The present invention can be realized not only as an apparatus but also as a method. A part of the invention can be configured as software. Furthermore, a software product used for causing a computer to execute such software and a recording medium in which the product is fixed to a recording medium are naturally included in the technical scope of the present invention (the same applies throughout the present specification). Is).

  The “communication unit” (0401) is configured to be able to transmit operation signals to a plurality of display devices. Specifically, for example, by adopting a bidirectional communication method such as IrSimple, Bluetooth, and RF (Radio Frequency), the communication unit transmits various operation signals to the display device, and an aspect ratio from the display device described later. Information or the like may be received. Of course, the communication unit may be configured as a one-way communication method such as an infrared communication method as before, and information acquisition from a display device described later may be performed by another hardware.

  The remote control device according to the present embodiment is characterized in that the communication unit is “configured to be able to transmit operation signals to a plurality of display devices”, that is, a so-called “general-purpose remote control”. Therefore, the remote control device according to the present embodiment means that a plurality of display devices having various aspect ratio screens can be operated.

  The “touch pad portion” (0402) has a function of remotely operating the display screen. For example, a touch pad such as a sensor that performs contact detection or non-contact detection by an electrostatic type, a pressure-sensitive type, an optical type, a radio wave type, or the like. Is mentioned. The touch pad unit may be a so-called “touch screen” further provided with an information display function. In the touch pad unit, the touch position on the touch pad is detected by the above detection method, and an operation signal corresponding to the touch position is transmitted from the communication unit to the display device.

  However, as described above, when the aspect ratio of the touch pad is different from the aspect ratio of the display screen, there is an area on the touch pad that is not reflected in the operation of the display device even if the touch pad is touched. Become. Therefore, in the remote control device of the present embodiment, the non-operable area of the touch pad of the remote control device is set according to the screen aspect ratio of the display device and the like by the following configuration.

  The “aspect ratio information acquisition unit” (0403) has a function of acquiring aspect ratio information of the display to be operated. For example, if the communication unit is realized by a bidirectional communication method, the same hardware as the communication unit Or a communication IF and a communication circuit that are separate from the communication unit. The “display aspect ratio” includes information indicating the aspect ratio of the screen size, as well as aspect ratio information of the display area and aspect ratio information of the number of pixel pixels, as described in the first embodiment.

  In addition, the aspect ratio information acquisition unit may be configured to receive information indicating the aspect ratio that is directly transmitted from the display device to be operated. Alternatively, internal search processing is performed by storing master data in which the aspect ratio information for each display device is associated with the display device ID and tabulated in the remote control device, and receiving the ID information from the display device to be operated. The aspect ratio information may be acquired by the above.

  Note that the aspect ratio information acquired by the aspect ratio information acquisition unit may be acquired by communication with a display device or the like. Therefore, the configuration requirements of the display device will be briefly described below. That is, the display device includes a “display”, an “information storage unit”, and a “communication unit”. Here, the “information storage unit” is realized by a storage medium such as a flash memory, for example, and stores the aspect ratio information of its own display, ID information for identifying itself, and the like. When the request signal from the remote control device of the present embodiment is received by the “communication unit”, the aspect ratio information stored in the “information storage unit” and its own ID information are transferred from the “communication unit” to the remote control device. For example, a reply is made. In this way, the aspect ratio information can be acquired by the remote control device of the present embodiment.

  In addition to obtaining aspect ratio information by communication with such a display device, the aspect ratio information may be obtained by a remote control device as follows. For example, on the display device side, the light spot is moved and displayed at a predetermined speed from the upper end to the lower end of the display. On the remote control device side, the movement of the light spot is detected by a camera or the like, and the vertical length of the display is calculated from the movement time and speed. Similarly, the horizontal length of the display is calculated by moving the light spot from the left end to the right end, and the aspect ratio information is acquired. Alternatively, the entire display is displayed in blue or the like on the display device, and is acquired as image information by a camera or the like of the remote control device. Then, the aspect ratio of the blue region indicated by the acquired image may be calculated and the aspect ratio information of the display may be acquired.

  The “arithmetic expression storage unit” (0404) has a function of storing an arithmetic expression for specifying an inoperable area in the touch area of the touchpad based on the aspect ratio information. For example, a flash memory, a small HDD, and the like This can be realized by a small recording medium suitable for a remote control device. The “inoperable area” refers to an area that should be set in the touch area so that the aspect ratio of the operable area in the touch area of the touchpad unit is the same as the aspect ratio of the display.

  FIG. 5 is a diagram illustrating an example of an arithmetic expression stored in the arithmetic expression storage unit. As shown in this figure, for example, if the aspect ratio of the display is “Y: X”, the aspect ratio of the touchpad is “b: a”, and the value of “bX−aY” is 0, the aspect ratio of both is Since they are the same, there is no need for an arithmetic expression for setting the non-operational area. On the other hand, if the value of “bX−aY” is greater than 0, the touch pad is vertically longer than the display, and therefore the arithmetic expression “k = 1/2 (bX / a) -Y) "(k: vertical ratio of the area that cannot be operated) is stored. Also, if the value of “bX−aY” is less than 0, the touch pad is horizontally longer than the display, and therefore an arithmetic expression “k ′ = 1/2 (aY / B−X) ”(k ′: the horizontal ratio of the area that cannot be operated) is stored.

  In addition, since the aspect ratio of the touch pad provided in the remote control device can be specified in advance, an expression in which the values of a and b are already substituted may be stored. In addition, the screen aspect ratio of the display is calculated according to these aspect ratios in advance because there are general aspect ratios such as standard size (aspect ratio 3: 4) and vista size (aspect ratio 9:16). The table data that determines the ratio of the vertical (or horizontal) of the non-operable area may be stored as an arithmetic expression.

  FIG. 6 is a diagram illustrating an example of table data stored as the arithmetic expression. For example, a remote control device having a touchpad aspect ratio of 3: 4 stores table data as shown in FIG. That is, in this case, if the screen aspect ratio of the display is “9:16”, the upper and lower “n × 1/8” pixels (where n is the vertical resolution of the touchpad) is set as the non-operational area. Is an arithmetic expression. Further, for example, a remote controller having a touchpad with an aspect ratio of 1: 1 stores table data as shown in FIG. 6B.

  The “inoperable area calculation unit” (0405) has a function of calculating the inoperable area in accordance with the aspect ratio information and the arithmetic expression, and can be realized by an arithmetic device such as a CPU and a main memory. Specifically, an arithmetic expression as shown in FIG. 5 is read from an arithmetic expression storage unit such as a flash memory. Then, the aspect ratio information (X, Y) of the display acquired by the aspect ratio information acquisition unit and the aspect ratio information (a, b) of the touch pad stored and held in advance in its own flash memory or the like are read. In other words, a value for determining the non-operational area is calculated by a calculation process such as a CPU, which is substituted for each value of the calculated expression.

  FIG. 7 is a diagram illustrating an example of a calculation result in the non-operational area calculation unit. As shown in this figure, when the aspect ratio of the display is “9:16” and the vertical / horizontal resolution of the touchpad is 320 × 240 (pixels), it is indicated by hatching according to the arithmetic expression shown in FIG. That is, the upper and lower 30 (pixels) are calculated as the non-operational area.

  If the arithmetic expression is table data as shown in FIG. 6, the aspect ratio information of the display acquired by the aspect ratio information acquisition unit is used as a key to correspond to the aspect ratio information by logical operation processing such as a CPU. You may perform the process which acquires the value for determining an operation impossible area | region.

  The “operation impossible setting unit” (0406) has a function of setting an area specified as an operation disabled area within the touch area of the touch pad unit to be operation disabled based on a calculation result in the operation disabled area calculation unit. Specifically, “setting to disable operation” means, for example, a method that is realized programmatically by, for example, a configuration in which a touch signal in an operation disabled area determined by calculation is not processed, or a physical cover is placed on the touch pad. And a method of physically realizing the operation impossible area. In addition, when a location set as an operation disabled area is touched, a warning sound for prompting a retouch input may be transmitted, or an icon display for notifying the touch operation disabled on the touch screen may be performed.

  In this way, in the remote control device of this embodiment, it is possible to set the non-operable area of the touch pad of the remote control device in accordance with the screen aspect ratio of the display device. Then, when the user touches the location where the operation is impossible, the user's touch operation can be made efficient by performing notification or the like.

<Hardware configuration>
FIG. 8 is a schematic diagram illustrating an example of a configuration of the remote control device when the above functional components are realized as hardware. The operation of each hardware component in the non-operation area setting process will be described with reference to FIG.

  As shown in this figure, the remote control device is an inoperable area calculation unit, and also includes a “CPU (central processing unit)” (0801) for performing various other calculation processes and a “main memory” (0802). I have. Also, “flash memory” (0803) which is an arithmetic expression storage unit, “communication IF” (0804) which is a communication unit and aspect ratio information acquisition unit, “(touchpad)” which is a touch pad unit and an operation disable setting unit A “control mechanism” (0805) and a “touchpad” (0806) are also provided. They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information.

  A program is read out to the “main memory”, and the “CPU” executes various arithmetic processes by referring to the read out program. In addition, a plurality of addresses are assigned to each of the “main memory” and “flash memory”, and in the calculation processing of the “CPU”, the addresses are specified and accessed to store the data. It is possible to perform arithmetic processing using.

  Here, first, by outputting a control command of the “CPU” in accordance with the aspect ratio information acquisition program, a transmission request for the aspect ratio information is output from the “communication IF” to the display device by, for example, bidirectional communication with the display device. . Then, as a response, the “display aspect ratio” received by the “communication IF” is stored in the address 1 of the “main memory”.

  Subsequently, the arithmetic expression stored at the address A of the “flash memory” is read to the address 2 of the “main memory” in accordance with the non-operation area calculation program. In some cases, aspect ratio information of its own “touch pad” (not shown) is read from “flash memory” to a predetermined address of “main memory”. Then, the numerical value indicating the aspect ratio is substituted into the arithmetic expression by the arithmetic processing of “CPU” to calculate the value k. Then, the value k is stored as the calculation result at address 3 of the “main memory”. Then, according to the calculation result, a command for setting the non-operational area is generated by calculation such as “k × number of resolution pixels” by CPU calculation processing, for example, and stored in address 4 of “main memory”.

  Then, for example, whether or not the touch position information (coordinate information) acquired by processing such as “control mechanism” by touching the “touch pad” is a coordinate included in the operation disabled area indicated by the operation disabled setting command. The determination process is executed by a calculation process of “CPU” according to the operation disabling setting program. When a determination result indicating that the touch position is within the non-operation area is output, for example, for issuing a warning sound for prompting a re-touch input or displaying an icon for notifying the touch operation on the touch screen Execute the process.

  Further, according to the communication program, touch position information to the “touch pad” area other than the non-operable area set by the process is transmitted from the “communication IF” as an operation signal.

  The “identification display unit” (1007) has a function of displaying the touch area of the touch pad unit, which is disabled by the operation disabled setting unit, as an operation disabled area so as to be identifiable to the user. Specifically, for example, the touch pad is configured as a “touch screen” having an information display function, and the user identifies both areas by displaying the non-operable area and the other operable areas on the touch screen in different colors. There is a method of displaying as possible. In addition, by drawing a line at the boundary between the non-operable area and the operable area, a method of displaying the areas so that the user can identify both areas is also included.

  Then, the non-operable area and the operable area on the touchpad are displayed in such a manner that they can be identified by the user, thereby preventing the user from touching the non-operable area without noticing. . Therefore, it is possible to provide the user with a comfortable operating environment that is less stressful than the first embodiment.

Example 4
<Overview>
FIG. 12 is a conceptual diagram illustrating an example of remote operation of the display device using the touch pad by the remote control device of the present embodiment. As shown in this figure, in the remote control device of the present embodiment, the coordinate information of the touch position B on the touch pad having an aspect ratio of 3: 4 is obtained from the position A on the display having an aspect ratio of 9:16. The coordinate information is converted by a mapping function and transmitted.

<Functional configuration>
FIG. 13 is a diagram illustrating an example of functional blocks in the remote control device according to the present embodiment. As shown in this figure, the “remote control device” (1300) of this embodiment includes a “communication unit” (1301), a “touch pad unit” (1302), and an “aspect ratio information acquisition unit” (1303). , “Mapping function holding unit” (1304), “touch position acquisition unit” (1305), and “conversion unit” (1306). Note that the “communication unit”, “touch pad unit”, and “aspect ratio information acquisition unit” in the remote control device of the present embodiment have the same functions as the configuration requirements of the same name in the second embodiment, so that specific Description is omitted.

  The “mapping function holding unit” (1304) has a function of holding a plurality of types of mapping functions between the touch position on the touch pad and the designated position on the display in accordance with the display aspect ratio information. For example, a flash memory or a small HDD In addition, it can be realized by a small recording medium suitable for a remote control device.

  FIG. 14 is a diagram illustrating an example of the mapping function held in the mapping function holding unit. As shown in this figure, for example, the aspect ratio of the display is “Y: X”, and the aspect ratio of the touchpad is “b: a”. When the position coordinates of the center point of both are (0, 0), the mapping position coordinate Z on the display of the touch position coordinates (x, y) of the touchpad is Z = (X / a, Y / b) ( x, y)... (1). Therefore, the mapping function holding unit holds the expression (1) as a mapping function, and the acquired aspect ratio (Y: X) of the display and the aspect ratio (b: a) of the touch pad held in advance are expressed by the above expression. By substituting into, a plurality of mapping functions corresponding to the aspect ratio of the display may be held. As described above, “holding a plurality of types of mapping functions in accordance with display aspect ratio information” refers to a mode in which a plurality of mapping functions can be generated by substituting display aspect ratio information into the mapping function of equation (1). It is a concept that also includes

  Alternatively, the aspect ratio of the display assumed in advance and the aspect ratio of its own touchpad are substituted into the above equation (1), and the table data in which the aspect ratio of the substituted display and the mapping function are associated is held. However, the mapping function may be selected from the table data using the display aspect ratio information as a key.

  The “touch position acquisition unit” (1305) has a function of acquiring a touch position on the touch pad unit. For example, in the case of an electrostatic touch pad, the touch pad unit obtains the touch position by detecting the change in the capacitance by the electrodes arranged in a grid pattern and determining the position (coordinate information) where the finger is placed. The touch position information may be acquired by a method similar to the conventional method that matches the detection method of the touch pad.

  The “conversion unit” (1306) has a function of converting the touch position acquired using the mapping function selected from the mapping function holding unit based on the acquired display aspect ratio information into an indicated position on the display, for example, a CPU. And an arithmetic unit such as a main memory. Specifically, for example, in the expression (1) which is a mapping function held in the detected flash memory or the like, the aspect ratio (9:16) of the acquired display and the aspect ratio (3 : 4) and the like are substituted, and Z = (4, 3) (x, y) is selected (generated). Then, the touch position coordinates (x, y) detected by the touch pad by the arithmetic processing of the CPU are substituted into the selected mapping function, and the coordinate information Z after the mapping conversion is calculated. Alternatively, if the mapping function is held as table data in accordance with the aspect ratio of the display, the corresponding mapping function expression is acquired from the table data using the acquired aspect ratio information as a key, and the transformation coordinates are converted by CPU processing. Information may be calculated.

  Thus, even when the aspect ratio of the display and the touch pad is different, the coordinates of the touch position can be converted into the mapping position on the display using the mapping function. Accordingly, there is no area where the operation is invalid in all the areas on the touch pad, so that the user can operate without stress.
