It is possible to use a touch sensor having an area that overlaps the display unit 230. The input / output device is provided with a display unit 230 and a touch sensor having an area overlapping the display unit 230. The force device may be referred to as a touch panel or touch screen.

[0424] For example, the user can use a finger that touches the touch panel as a pointer to perform various gestures (tabbing). You can move the cursor (click, drag, swipe or pinch in, etc.).

[0425] For example, the computing device 210 analyzes information such as the position or trajectory of a finger touching the touch panel. When the analysis result satisfies a predetermined condition, it can be assumed that a specific gesture has been provided. This allows the user to select a specific gesture that is pre-associated with the specific gesture. Operation instructions can be provided using the gestures.

[0426] For example, the user can issue a "scroll command" to change the display position of image information by tapping. The gesture can be provided by moving a finger along the touch panel. .

[0427] <Detection unit 250> The detection unit 250 has a function of detecting the surrounding conditions and supplying the detection information. It can provide illumination information, posture information, pressure information, position information, etc.

[0428] For example, photodetectors, attitude detectors, acceleration sensors, orientation sensors, GPS (Global Positioning System) Positioning System) signal receiving circuit, pressure sensor, temperature sensor, humidity sensor A sensor, a camera, or the like can be used for the detection unit 250.

[0429] Communications Department 290 The communication unit 290 has the function of supplying information to the network and acquiring information from the network. Prepare.

[0430] "program" A program according to one embodiment of the present invention includes the following steps (see FIG. 17(A)).

[0431] [First Step] In the first step, the settings are initialized (see FIG. 17(A)(S1)).

[0432] For example, predetermined image information to be displayed at startup and a predetermined mode in which the image information is displayed; and information specifying a predetermined display method for displaying the image information, from the storage unit 212. Specifically, one still image or other moving image information can be used as the predetermined image information. Also, the first mode or the second mode can be used for a predetermined mode.

[0433] [Second step] In the second step, interrupt processing is permitted (see FIG. 17(A)(S2)). The processor that is allowed to process the interrupt can process the interrupt in parallel with the main processing. The processing unit that returns to the main processing from the interrupt processing can This can be reflected in the main processing.

[0434] When the counter value is the initial value, the arithmetic unit is caused to perform an interrupt process. When returning from the program, the counter may be set to a value other than the initial value. After starting up, you can always have the interrupt process run.

[0435] [Third Step] In the third step, the predetermined The image information is displayed using the mode or a predetermined display method (see FIG. 17(A)(S3)). The predetermined mode specifies the mode in which information is displayed, and the predetermined display method specifies the image information. Also, for example, the information to display the image information V1 or the information V11 is specified. It can be used for.

[0436] For example, one way of displaying image information V1 can be associated with a first mode. Alternatively, other ways of displaying the image information V1 can be associated with the second mode. This allows the display method to be selected based on the selected mode.

[0437] First Mode Specifically, a selection signal is applied to one scanning line at a frequency of 30 Hz or more, preferably 60 Hz or more. The method of providing the display based on the selection signal can be associated with the first mode.

[0438] For example, if a selection signal is supplied at a frequency of 30 Hz or more, preferably 60 Hz or more, a moving image The movement can be displayed smoothly.

[0439] For example, if the image is updated at a frequency of 30 Hz or more, preferably 60 Hz or more, the user's operation The image that changes smoothly in accordance with the user's operation is displayed on the information processing device 200 that the user is operating. It can be shown.

[0440] Second Mode Specifically, the frequency is less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. The method of supplying a selection signal to one scanning line at a time and displaying based on the selection signal is called the second mode. It can be associated with a

[0441] A selection signal at a frequency of less than 30 Hz, preferably less than 1 Hz, and more preferably less than once per minute. By supplying the above, it is possible to display a picture with reduced flicker or flicker. Power consumption can be reduced.

[0442] For example, when the information processing device 200 is used as a clock, the frequency is once per second or once per minute. The display can be updated with frequency, etc.

[0443] [Fourth step] In the fourth step, if a termination command is provided, the process proceeds to the fifth step. If no signal is supplied, the process proceeds to the third step (FIG. 17(A)(S4) reference).

[0444] For example, the termination command supplied in the interrupt process may be used for the determination.

[0445] [5th step] In the fifth step, the process ends (see FIG. 17(A)(S5)).

[0446] Interrupt handling The interrupt process comprises the following sixth to eighth steps (see FIG. 17(B)). .

[0447] [Sixth step] In the sixth step, for example, the detection unit 250 is used to detect whether the information processing device 200 is being used. The illuminance of the environment is detected (see FIG. 17(B)(S6)). The color temperature and chromaticity of the ambient light may also be detected.

[0448] [Seventh step] In the seventh step, a display method is determined based on the detected illuminance information (see FIG. 17( B) (see S7)). For example, the brightness of the display should not be too dark or too bright. It is decided that

[0449] If the color temperature or chromaticity of the ambient light is detected in the sixth step, the display The color may be adjusted.

[0450] [Eighth Step] In the eighth step, the interrupt process ends (see FIG. 17(B) (S8)).

[0451] <Configuration example 2 of information processing device> Another configuration of a data processing device of one embodiment of the present invention will be described with reference to FIG.

[0452] FIG. 18A is a flowchart illustrating a program according to one embodiment of the present invention. (A) is a flowchart illustrating an interrupt process different from the interrupt process shown in FIG. 17(B). It is a chart.

[0453] The second example of the information processing device changes the mode based on a given event. The fact that the interrupt process includes a step for performing the above operation is the same as that of the interrupt process described with reference to FIG. This section will explain the differences in detail and explain how to use a similar configuration. The above explanation will be used for the parts that can be described.

[0454] <<Interrupt Processing>> The interrupt process comprises the following steps 6 to 8 (see FIG. 18(A)). .

[0455] [Sixth step] In the sixth step, if a predetermined event is provided, the process proceeds to the seventh step; If the predetermined event is not provided, proceed to the eighth step (FIG. 18(A) (U6 For example, you can use the condition whether a specific event was provided within a specific period. Specifically, it is possible to perform the above-mentioned operation for 5 seconds or less, 1 second or less, or 0.5 seconds or less, preferably 0.1 seconds or less. The predetermined period may be a period longer than 0 seconds.

[0456] [Seventh step] In the seventh step, the mode is changed (see FIG. 18(A)(U7)). Specifically, If you have selected the first mode, select the second mode, and then select the second mode. If so, select the first mode.

[0457] For example, the display mode can be changed for a part of the area of the display unit 230. Specifically, a display unit 230 including a drive circuit GDA, a drive circuit GDB, and a drive circuit GDC The display mode can be changed for the area where the driver circuit GDB supplies the selection signal. (See FIG. 18(B)).

[0458] For example, a predetermined event may occur at the input 240 of the area to which the driver circuit GDB supplies a selection signal. When the signal is supplied, the display mode of the corresponding area can be changed. The frequency of the selection signal supplied by the GDB can be changed. The display of the area where the circuit GDB supplies the selection signal is shown by the driver circuit GDA and the driver circuit GDC. It is possible to update without operating the device, or to reduce the power consumed by the drive circuit. This can be done.

[0459] [Eighth Step] In the eighth step, the interrupt process is completed (see FIG. 18(A)(U8)). The interrupt process may be repeatedly executed during the period when the main process is being executed.

[0460] 《Specified Events》 For example, "click" and "drag" operations are performed using a pointing device such as a mouse. Events such as "tap" and "drag" are supplied to the touch panel using a finger as a pointer. Events such as "click" or "swipe" can be used.

[0461] Also, for example, the position of the slide bar pointed by the pointer, the speed of the swipe, the speed of the drag, The degree or the like can be used to provide arguments for the command associated with a given event.

[0462] For example, the information detected by the detection unit 250 is compared with a preset threshold value, and the comparison result is can be used for events.

[0463] Specifically, a pressure-sensitive detector that comes into contact with a button or the like that is arranged so that it can be pressed into the housing. etc. can be used in the detection unit 250.

[0464] Commands associated with specific events For example, a termination command can be associated with a particular event.

[0465] For example, the "page turning" function is used to switch the display from one image information to another. The "page turn command" can be associated with a specific event. The arguments that determine the page turning speed, etc., used when executing are passed using a specified event. can be given.

[0466] For example, the display position of a part of one image information is moved to display a part of the image information that is continuous with the part. You can associate a "scroll command" to display other parts with a specified event. In addition, it determines the speed at which the display moves when executing the "scroll command." Arguments can be provided with a given event.

[0467] For example, a command to set a display method or a command to generate image information is generated as a predetermined event. It is possible to associate the argument that determines the brightness of the generated image with a specific event. In addition, the argument that determines the brightness of the generated image can be associated with the The determination may be based on the brightness of the environment detected by the 50 .

[0468] For example, information distributed using a push-type service can be acquired using the communication unit 290. An instruction to execute a command can be associated with a given event.

[0469] The qualification to obtain information is determined using the location information detected by the detection unit 250. Specifically, the user may be inside or outside a specific classroom, school, conference room, company, building, etc. If a person is in a certain area, it may be determined that the person is entitled to obtain information. , and receives teaching materials distributed in classrooms of schools or universities, etc., and uses the information processing device 200 to (See Figure 16(C)). Or, it can be used for materials distributed in conference rooms of companies, etc. can be received and used for conference materials.

[0502] In addition, the circuit diagram shows independent components as if they are electrically connected to each other. Even if the components are different, one component may have the functions of multiple components. For example, when a part of the wiring also functions as an electrode, one conductive film functions as both the wiring and the electrode. Therefore, the electrode in this specification has the functions of both components. The term "electromagnetic connection" refers to a case where one conductive film has the functions of multiple components. This also falls within the scope of the above. [Explanation of symbols]
