Description

  The present disclosure relates to control of a display device, and more particularly to control of a display device capable of touch operation.

  Among devices provided with a touch panel, there are devices provided with a plurality of input modes. Multiple input modes can be switched by a specific operation.

  With regard to switching of the input mode, for example, Japanese Patent Laid-Open No. 2014-134968 (Patent Document 1) describes “the user at the time of flick input for two types of input operations of flick input requiring different detection accuracy and handwriting input. Discloses a pressure-sensitive touch panel device that reduces the possibility of impairing the user's sense of operation. Specifically, in the navigation system 100 having the display unit 3 configured by the display panel 20 and the touch panel unit 10 (paragraphs 0018 and 0019, FIG. 1), the touch panel unit 10 has two input modes (flick input mode, handwriting Input mode) (paragraph 0021). The user switches the input mode, for example, by double tapping (paragraph 0026). More specifically, the mode switching operation is performed, for example, in the following order. (1) The first touch on the touch panel is performed. → (2) Release your finger from the touch panel. → (3) A second touch is performed → (4) A finger is spoken from the touch panel → (5) An input mode is switched → (6) A touch is performed again to perform an input operation. According to this technology, when the double tap operation is finished (point of time (4) above), the input mode is switched (point of time (5) above) and the new mode is started from the point of time when touching again (point of time (6) above) The input operation at is started.

JP 2014-134968 A

  According to the technology disclosed in Japanese Patent Laid-Open No. 2014-134968, mode switching is performed with the finger or pen operating away from the touch panel, and the mode switching operation and the input operation after (6) are completely separated. ing. In other words, so-called double tap (also referred to as mode switching operation, double touch) and subsequent operation become discontinuous. As a result, the user's thinking is divided and the convenience is lost. Therefore, there is a need for a technique that does not impair the convenience in mode switching.

  The present disclosure has been made to solve the problems as described above, and an object in one aspect is to provide a display device in which a decrease in convenience due to mode switching is prevented. An object in another aspect is to provide a program for controlling a display device such that a decrease in convenience due to mode switching is prevented.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the following description, the same components are denoted by the same reference numerals. Their names and functions are also the same. Therefore, detailed description about them will not be repeated.

[Technical thought]
First, the technical concept of the display device disclosed in the following embodiment will be described. The technical idea is to switch the input mode by double touch and to perform the next operation in the touched state. More specifically, it is as follows.
(1) The user of the display device performs the first touch operation.
(2) The user releases the finger or other input means from the touch panel.
(3) The user performs the second touch operation.
(4) While the user maintains the touch on the touch panel, the display device switches the operation mode to the handwriting input mode. The user can realize handwriting input by moving a finger or other input means on the touch panel.

First Embodiment
The configuration of the display device 100 according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram showing a hardware configuration of a display device 100. As shown in FIG. The display device 100 includes a touch panel 110, a touch panel control unit 120, a processor 130, a memory 150, a display driver 170, and a display 180. In the present embodiment, display device 100 is, for example, a smartphone, a tablet terminal, and other devices, but is not limited thereto. The display device 100 includes at least a touch panel (also referred to as a touch screen).

  The touch panel 110 receives an operation on the display device 100, and sends a signal corresponding to the operation to the touch panel control unit 120. The touch panel control unit 120 sends a control signal corresponding to the signal to the processor 130. For example, touch panel 110 detects a touch operation on each of the upper end region and the lower end region, and sends coordinate values of the position at which the touch operation is performed to touch panel control unit 120, respectively.

  The processor 130 controls the operation of the display device 100 based on the control signal. The memory 150 holds programs and data that the display device 100 executes. The memory 150 is realized by a random access memory (RAM) or other volatile storage device, a flash memory, a hard disk drive or other non-volatile storage device.

  Display driver 170 controls display 180 based on the output from processor 130. The display 180 displays characters, images and the like based on the signal from the display driver 170. The display 180 is realized by a liquid crystal monitor, an organic EL (Electro Luminescence) monitor, or the like.

  In a certain aspect, when the touch panel control unit 120 detects two touch operations (double tap) on the touch panel 110 within a predetermined time, the processor 130 detects that the second touch continues. The operation mode of the display device 100 is switched to the handwriting input mode, and an input operation on the touch panel 110 is received.

  Here, switching the operation mode to the handwriting input mode is, for example, switching from the mode for receiving the flick operation to the handwriting input mode, but switching of the operation mode is not limited to this.

  If the touch panel control unit 120 further detects two new touches within a predetermined time after detecting the two touches, the processor 130 cancels the handwriting input mode, and the display device Switch the 100 operation mode to the normal mode.

  The configuration of the display device 100 will be further described with reference to FIG. FIG. 2 is a block diagram showing functions implemented by the display device 100. As shown in FIG. The display device 100 includes a touch panel 110, a touch state detection unit 210, a gesture detection unit 220, a data input unit 230, and an input mode switching unit 240. The touch state detection unit 210, the gesture detection unit 220, the data input unit 230, and the input mode switching unit 240 are realized by the processor 130.

  The touch state detection unit 210 detects a state of touch on the touch panel 110 or a locus in the touch-down state based on an output from the touch panel 110. In the present embodiment, the touch-down state means that a state in which a finger, a stylus pen or other input device is in contact with the touch panel 110 continues.

  The gesture detection unit 220 detects a gesture (operation) on the touch panel 110 based on the output from the touch state detection unit 210. For example, the gesture detection unit 220 performs an operation (switching gesture) for switching the input mode of the display device 100 based on the touch state detected by the touch state detection unit 210 and the locus in the touch down state. Detect that it has been In another aspect, the gesture detection unit 220 detects that another operation has been performed. Other operations may include, for example, single tap (also referred to as single touch) operation, double tap operation, and other operations.

  The data input unit 230 executes, based on an operation other than the operation (switching gesture) detected by the gesture detection unit 220, a process defined in advance for the operation.

  The input mode switching unit 240 switches the input mode of the display device 100 based on the output from the gesture detection unit 220. For example, the input mode switching unit 240 switches the input mode of the display device 100 between the flick mode and the handwriting input mode according to a signal indicating the content of the touch operation on the touch panel 110. In the present embodiment, the flick mode refers to an operation mode that accepts flick input. The handwriting input mode can receive not only input by the finger of the user of the display device 100 but also input by a stylus pen or other input device.

Control structure
The control structure of the display device 100 according to the present embodiment will be described with reference to FIG. FIG. 3 is a flowchart showing a part of a plurality of operations performed by the processor 130 of the display device 100. In one aspect, the plurality of operations are realized by the processor 130 executing instructions that constitute a program. Note that in another aspect, some or all of the plurality of operations may be realized by circuit elements or other hardware that performs the operations.

  In step S310, processor 130 detects, based on the signal from touch panel control unit 120, that touch input to touch panel 110 has been performed.

  In step S320, the processor 130 determines whether the touch input is a double touch. More specifically, the processor 130 performs a first touch operation on the touch panel 110, a release of the first touch operation (a finger or other input device being separated from the touch panel 110), and a first touch operation. It is detected that the second touch operation on the touch panel 110 is performed within a predetermined time. If processor 130 determines that the touch input is a double touch (YES in step S320), it switches control to step S330. If not (NO at step S320), processor 130 switches control to step S325.

  In step S325, the processor 130 executes a predetermined process for a touch operation other than double touch. Thereafter, control is returned to step S310.

  In step S330, the processor 130 switches the operation mode of the display device 100 from the flick mode to the handwriting input mode. The operation mode before switching to the handwriting input mode is not limited to the flick mode.

  In step S335, the processor 130 temporarily holds the current touch position in a register (not shown) of the processor 130 as an input start point. The processor 130 receives a signal from the touch position at which the second touch operation has been performed as an input signal.

  In step S340, based on the signal from touch panel control unit 120, processor 130 detects that a touch input to touch panel 110 has been performed.

  In step S350, the processor 130 determines whether the touch input is a double touch. More specifically, the processor 130 performs a first touch operation on the touch panel 110, a release of the first touch operation (a finger or other input device being separated from the touch panel 110), and a first touch operation. It is detected that the second touch operation on the touch panel 110 is performed within a predetermined time. If processor 130 determines that the touch input is a double touch (YES in step S350), it switches control to step S360. If not (NO in step S350), processor 130 switches control to step S355.

  In step S355, the processor 130 executes a process defined in advance for touch operations other than double touch. Thereafter, control is returned to step S340.

  In step S360, processor 130 switches the operation mode of display device 100 from the handwriting input mode to the flick mode. The operation mode switched from the handwriting input mode is not limited to the flick mode. The handwriting input mode may be switched to another operation mode by setting by the user of the display device 100.

  In step S370, the processor 130 stores the current touch position in the register as the touch start point. The processor 130 receives a signal from the touch position at which the second touch operation has been performed as an input signal.

  In step S380, the processor 130 executes a process according to the touch state. The processing is, for example, movement of a screen based on a flick operation, activation of an application associated with an icon for which single touch has been performed, and the like, but the processing to be executed is not limited to these.

[Display screen]
The display mode of the screen of the display device 100 will be described with reference to FIG. FIG. 4 is a diagram showing the transition of the screen on the display 180 of the display device 100 according to the present embodiment.

  In the state (A), the display 180 displays the pointer 400 based on the touch of the finger 410 on the touch panel 110. The pointer 400 represents a position when an input is temporarily performed on the touch panel 110. At this time, the operation mode of the display device 100 is the flick mode.

  As shown in the state (B), when the user moves the finger 410 above the touch panel 110 while touching the touch panel 110, the image displayed on the display 180 also moves (scrolls) upward. Thereafter, when the user releases the finger 410, the processor 130 ends the processing (image movement) based on the flick operation.

  When the user again touches the touch panel 110 with the finger 410 and moves the finger 410 in the left direction, only the pointer 400 moves in the left direction as shown in the state (C). When the user releases the finger 410 from the touch panel 110, the processor 130 ends the drag operation.

  Thereafter, when the user performs a double touch operation on the touch panel 110 (performing two touch operations within a predetermined period), the processor 130 sets the operation mode of the display device 100 to the handwriting input mode. . As shown in the state (D), when the user touches the touch panel 110 with the finger 410, the processor 130 receives handwriting input from the point at which mode switching has been performed based on a signal from the touch panel control unit 120. While the operation mode of the display device 100 is the handwriting input mode, the user may temporarily release the finger 410 from the touch panel 110. For example, the finger 410 is temporarily released from the touch panel 110 according to the character input by handwriting. In this case, the operation mode of the display device 100 is not changed, and the handwriting input mode is maintained.

  The state (E) shows a state in which the handwriting input is completed. When the user releases the finger 410 from the display 180 and then performs two touch operations within a predetermined time, the display device 100 switches the operation mode from the handwriting input mode to the flick mode.

  The state (F) represents the display device 100 in the flick mode. When the display device 100 is in the flick mode, the display 180 displays the pointer 400 again. When the user performs a downward scroll operation while touching the display 180 with the finger 410, the pointer 400 moves downward, and the image displayed on the display 180 also moves downward according to the movement. Do.

  As described above, according to the display device 100 according to the present embodiment, when the user performs the touch operation twice, the operation mode of the display device 100 is changed. For example, the display device 100 switches the handwriting input mode to the flick mode, or conversely switches the flick mode to the handwriting input mode. With such a configuration, switching to the handwriting input mode is performed at the second touch, and handwriting input can be continuously performed continuously from that state (a state where the user's finger 410 touches the display 180). As a result, since the finger 410 of the user does not leave the touch panel 110, the operation is not interrupted, and the convenience of the user is improved. Specifically, the user can start the input operation with fewer procedures. Moreover, the shift of the touch position during the mode switching operation can be reduced. Furthermore, since extra operations are not performed to switch the input mode, it is possible to reduce the interruption of thinking.

Second Embodiment
The image displayed in the flick mode is not limited to the pointer 400. For example, an arrow indicating a scrollable direction may be displayed in a semitransparent state. In this way, the user of display device 100 can easily know in which direction scroll can be performed.

  The display device 100 according to the second embodiment can be realized using the same hardware configuration as the display device 100 according to the first embodiment. Therefore, the description of the hardware configuration will not be repeated.

Third Embodiment
The display device 100 according to the present embodiment can also be realized by a combination of software for realizing the operation and hardware for executing the operation as shown in the first embodiment. For example, in another aspect, circuit elements or other hardware for realizing the operation may be used in the display device 100.
