Hereinafter, embodiments of the present technology will be described. The description will be made in the following order.
1. First embodiment (gesture input correction function)
2. Second embodiment (inputable area display function)

<First Embodiment>
A gesture input correction function, which is a function for correcting gestures by showing options when a user's input gesture is not recognizable, will be described.

[Appearance of information processing terminal]
FIG. 1 is a diagram illustrating an example of an appearance of an information processing terminal according to an embodiment of the present technology.

  The information processing terminal 1 in FIG. 1 is a portable terminal such as a smartphone, a mobile phone, a PDA (Personal Digital Assistants), or a PND (Portable Navigation Device), and has a size that can be carried by a user with one hand. have.

  A display unit 11 made of an LCD (Liquid Crystal Display) or the like is provided on the front surface of the casing of the information processing terminal 1. A touch panel 25 is provided on the upper surface of the display unit 11 so that the user can directly operate the touch panel 25 at a position corresponding to information displayed on the display unit 11 with a finger or the like. Below the display unit 11, an operation unit 12 including a plurality of buttons is provided.

[Configuration example of information processing terminal]
FIG. 2 is a block diagram illustrating an electrical configuration example of the information processing terminal 1.

  The information processing terminal 1 is configured by connecting a sensor unit 22, a camera 23, a communication unit 24, a touch panel 25, and a storage unit 26 in addition to the display unit 11 and the operation unit 12 to the controller 21. .

  The controller 21 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory) (not shown), and the like. The CPU of the controller 21 loads a program from the ROM and executes it using the RAM, and controls the overall operation of the information processing terminal 1.

  The sensor unit 22 is composed of a gyro sensor or the like, and detects shaking generated in the information processing terminal 1. The sensor unit 22 outputs the detected shaking information to the controller 21.

  The camera 23 has an image sensor such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor, and performs photoelectric conversion of light taken in by a lens (not shown) provided on the front side of the casing of the information processing terminal 1. To generate image data. An image photographed by the camera 23 is supplied to the controller 21.

  The communication unit 24 communicates with devices on a network such as a LAN (Local Area Network) or the Internet. For example, information such as a web page received by the communication unit 24 is displayed on the display unit 11.

  A transparent touch panel 25 is provided on the upper surface of the display unit 11 and detects an operation of a user's finger or the like. The storage unit 26 includes a nonvolatile memory, a hard disk, and the like, and stores programs, data, and the like executed by the controller 21.

  FIG. 3 is a block diagram illustrating a functional configuration example of the controller 21. At least a part of the functional units shown in FIG. 3 is realized by executing a predetermined program by the controller 21 of FIG.

  In FIG. 3, the controller 21 is configured to include a gesture recognition unit 31, a recognition result correction unit 32, a correction information storage unit 33, a trajectory display unit 34, and a correction candidate generation unit 35.

  The gesture recognition unit 31 detects a gesture input by the user by tracing the touch panel 25 with a finger. In addition to the tracing operation described above, there are a plurality of operations in the gesture. For example, the gesture includes a tap operation in which the user touches the touch panel 25 once and a double tap operation in which the user touches the touch panel 25 twice. Further, for example, there is a flick operation in which the user touches the touch panel 25 with a finger 41 (see FIG. 4 described later) in an arbitrary direction. Furthermore, the gesture includes an operation in which the user's finger 41 draws a figure such as a circle or a triangle on the touch panel 25.

  In addition, the gesture recognition unit 31 recognizes which process the detected gesture is associated with among the processes executed by the information processing terminal 1. In other words, when there is no process associated with the detected gesture, the gesture recognition unit 31 determines that the gesture is an unrecognizable gesture.

  Furthermore, the gesture recognition unit 31 performs a process associated with the recognized gesture.

  The recognition result correction unit 32 performs a process of prompting the user to correct a gesture that the gesture recognition unit 31 cannot recognize. Specifically, for example, a gesture that can be recognized on the screen on which the user inputs a gesture or another gesture that is close to the gesture input by the user is displayed on the display unit 11 as options. Further, for example, when the region where the user inputs a gesture corresponding to the image on the display unit 11 is a region where the gesture cannot be recognized, the recognition result correction unit 32 displays a region where the gesture can be input.

  When the user inputs an unrecognizable gesture, the correction information storage unit 33 associates the unrecognizable gesture with the gesture selected by the user and stores it as correction information. The correction information storage unit 33 repeatedly stores correction information every time an unrecognizable gesture is detected. Based on the correction information accumulated in the correction information storage unit 33, the gesture recognition unit 31 learns the user's gesture. Further, the correction information storage unit 33 stores an ID (Identification) for specifying an application being displayed on the display unit 11 and an ID for specifying a screen in association with the gesture.

  The trajectory display unit 34 displays the gesture trajectory recognized by the gesture recognition unit 31 on the display unit 11. The trajectory display unit 34 creates an animation for reducing the gesture trajectory to a predetermined size, and displays the gesture having the predetermined size on the display unit 11 as a reduced trajectory. The reduced trajectory will be described later with reference to FIG.

  The correction candidate generation unit 35 can be recognized on the screen input by the user by referring to the ID for specifying the application currently displayed on the display unit 11 and the ID for specifying the screen, which are stored in the correction information storage unit 33. Or a gesture candidate close to a gesture that cannot be recognized is generated as an option. The correction candidate generation unit 35 is displayed on the display unit 11 with reference to the ID for specifying the application currently displayed on the display unit 11 and the ID for specifying the screen, which are stored in the correction information storage unit 33. An area in which a gesture can be input is detected from the existing image.

  FIG. 4 is a diagram illustrating a display example of the display unit 11. As described above, the transparent touch panel 25 is provided on the upper surface of the display unit 11, and the user visually recognizes the information displayed on the display unit 11 through the touch panel 25 and directly operates with the finger 41 or the like. .

  The user's finger 41 inputs a gesture to the touch panel 25. The user inputs a gesture by bringing the finger 41 into contact with the touch panel 25 and performing various operations on the touch panel 25. In the following, for the sake of simplicity, it is also described that a gesture is input to the display unit 11 as necessary.

  The display areas 51 to 54 are windows displayed on the display unit 11. In the display areas 51 to 54, images corresponding to contents and applications are displayed.

  The scroll bar 55 can move the image displayed on the display unit 11 to the right or left. That is, the user can move the image displayed on the display unit 11 left and right by flicking the scroll bar 55 in the horizontal direction.

  FIG. 5 is a diagram illustrating an example of gesture input. When the user inputs a gesture that draws a star on the display unit 11 with the finger 41 (hereinafter referred to as a “gesture (star)”), the gesture recognizing unit 31 performs the gesture with the finger 41 with the gesture (star). Recognize that there is. Further, the trajectory of the finger 41 recognized by the gesture recognition unit 31 is displayed as a gesture trajectory 61 by the trajectory display unit 34 at a position where the gesture 41 is input by the finger 41 of the display unit 11. The gesture recognizing unit 31 executes a process (for example, “open option menu”) associated with the input gesture (star).

[Operation of information processing terminal]
FIG. 6 is a flowchart for describing gesture input processing. The gesture input process is a process executed by the controller 21 when the user inputs a gesture to the display unit 11.

  FIGS. 7 to 10 are diagrams showing display examples when the gesture input process is executed. The processing of the flowchart of FIG. 6 will be described below with reference to FIGS.

  In step S1, the gesture recognition unit 31 detects a gesture. Specifically, in FIG. 7, the gesture recognition unit 31 detects a gesture input by the finger 41 on the display unit 11. That is, the gesture trajectory is detected.

  In step S <b> 2, the trajectory display unit 34 displays the gesture trajectory detected by the gesture recognition unit 31 in step S <b> 1 on the display unit 11. For example, as shown in FIG. 7, the trajectory display unit 34 displays a star-shaped gesture trajectory 62 on the display unit 11.

  In step S <b> 3, the gesture recognition unit 31 determines whether the detected locus is a recognizable gesture. If the detected gesture is not a recognizable gesture, NO is determined in step S3, and the process proceeds to step S5. For example, in FIG. 7, the gesture locus 62 looks like a gesture (star). However, compared to the gesture trajectory 61 shown in FIG. 5, the gesture trajectory 62 is tilted to the left. For this reason, the gesture recognizing unit 31 cannot recognize the gesture trajectory 62 as a gesture (star).

  In this case, the trajectory display unit 34 displays the reduced trajectory 71 in step S5. That is, as shown in FIG. 7, the trajectory display unit 34 displays an animation in which the gesture trajectory 62 moves while being gradually reduced in the lower left direction. Then, the trajectory display unit 34 displays the reduced trajectory 71 as an icon at the lower left as shown in FIG.

  Thus, by displaying the reduced trajectory 71, the user can know that the gesture performed by the user has not been recognized (rejected) by the gesture recognition unit 31.

  Next, in step S6, the recognition result correction unit 32 determines whether the reduced trajectory 71 has been tapped. That is, when the user knows that the input gesture has not been recognized since the reduced trajectory 71 is displayed, the user taps the reduced trajectory 71 to request input assistance. Therefore, as shown in FIG. 9, it is determined whether the user has tapped the reduced trajectory 71 with the finger 41.

  When the reduced trajectory 71 is tapped with the finger 41, it is determined as YES in Step S6, and the process proceeds to Step S7. In step S <b> 7, the recognition result correction unit 32 displays a recognition correction menu 81. That is, the recognition result correction unit 32 displays the recognition correction menu 81 generated by the correction candidate generation unit 35 on the display unit 11. The recognition correction menu 81 is a menu that presents to the user, as options, gestures that can be recognized on the screen on which the user has input a gesture (in this case, the screen in FIG. 9) in the order that the gesture that is recognized by the user is close. It is. When the gesture recognition unit 31 cannot recognize the gesture, the correction candidate generation unit 35 selects a gesture close to the input trajectory from the gestures that can be input, and generates the recognition correction menu 81.

  Specifically, as shown in FIG. 10, when the locus 71 is tapped with the finger 41, a recognition correction menu 81 is displayed on the display unit 11. The recognition correction menu 81 displays a gesture trajectory 62 input by the user and icons of options 91 to 93 as gesture candidates that can be recognized on this screen. For example, in the option 91, a sentence “open option menu” is displayed as an explanation of a process in which a gesture (star) is associated with a gesture (star). The option 92 includes a sentence “open a new window” as an explanation of a process in which a gesture that draws a triangle with the finger 41 (hereinafter referred to as a gesture (triangle)) and a gesture (triangle) are associated with each other. It is displayed. Further, the option 93 includes a sentence “draw window” as a description of a process in which the gesture 41 draws the alphabet letter W with the finger 41 (hereinafter referred to as a gesture (W)) and the gesture (W). Is displayed.

  By displaying these options 91 to 93, the user can confirm which gesture he / she intended to input. Then, the user selects one of the options, that is, the option corresponding to the gesture that the user actually wanted to input.

  In step S8, the recognition result correction unit 32 detects the selected option. That is, of the options 91 to 93 shown in FIG. 10, the option tapped with the finger 41 is detected.

  In step S9, the gesture recognition unit 31 executes a process associated with the gesture selected in step S8. That is, when the option 91 is tapped with the finger 41 among the options 91 to 93 shown in FIG. 10, for example, the gesture recognizing unit 31 executes a process of “opening the option menu”.

  In step S10, the recognition result correction unit 32 stores the correction information. That is, the correction information storage unit 33 associates the gesture trajectory 62 that is the detected trajectory of the gesture with the gesture (star) of the selected option 91 and stores it as correction information. In this way, the gesture input process is terminated. The correction information is repeatedly stored in the correction information storage unit 33 every time an unrecognizable gesture is detected. The gesture recognition unit 31 learns the user's gesture by referring to the accumulated correction information. Thereby, for example, when a gesture (star) tilted leftward is detected thereafter, the gesture is recognized as a gesture (star).

  On the other hand, if it is determined as NO in step S6, that is, if the reduced trajectory 71 is not tapped, the process proceeds to step S11.

  In step S11, the recognition result correction unit 32 determines whether a certain time has elapsed. If the predetermined time has not yet elapsed, it is determined as NO in Step S11, and the process returns to Step S6. In other words, the processes in step S6 and step S11 are repeated until a certain time elapses or the reduced locus is tapped.

  On the other hand, if it is determined in step S11 that a certain time has elapsed, the process proceeds to step S12.

  In step S12, the recognition result correction unit 32 deletes the reduced trajectory 71. That is, since the reduced trajectory 71 is not tapped even after a predetermined time has elapsed, it is determined that the reduced trajectory 71 is unnecessary information for the user, and the recognition result correction unit 32 deletes the reduced trajectory 71.

  The process when it is determined NO in step S3 has been described above. On the other hand, if YES is determined in step S3, that is, if the detected gesture is a recognizable gesture, the process proceeds to step S4. In step S4, the gesture recognizing unit 31 executes a process associated with the gesture. That is, when it is determined as YES in step S3, since it is not necessary to correct the gesture, the processes in steps S5 to S12 are not executed.

  In this way, by executing the gesture input process, the user can know that the gesture he / she made has been rejected. Moreover, the user can correct the gesture performed by displaying the gesture candidate as an option, and can execute the same processing as when the intended gesture is correctly input.

  In addition, by displaying the gesture trajectory input by the trajectory display unit 34, the user can infer the cause of the gesture being rejected, for example, the display unit 11 is dirty and the gesture is not recognized. Specifically, for example, when the line traced with the finger 41 is interrupted in the middle of the gesture trajectory, the user may infer that the portion where the gesture trajectory is interrupted cannot be recognized because the display unit 11 is dirty. it can. Thus, the user can recognize the correct gesture input by cleaning the display unit 11 or the like.

  When the gesture recognition unit 31 cannot recognize the gesture, the trajectory display unit 34 may display the reduced trajectory 71 and at the same time, the controller 21 may make a sound or vibrate the information processing terminal 1.

  The reduced trajectory 71 is deleted if it is not tapped by the user for a certain period of time, but it can also be configured as follows. That is, each time a different type of gesture is rejected, a new reduced trajectory 71 is additionally displayed. When the number of reduced trajectories 71 exceeds the upper limit (for example, 3), the oldest input is deleted in order. You may do it.

  Further, the reduced trajectory 71 is not limited to the display example of FIG. For example, the trajectory display unit 34 may form an animation in which the reduced trajectory 71 is floating softly. It is preferable to give an impression that is clearly different from the original display. Thereby, the recognition result correction | amendment part 32 can accelerate | urge | promote correction of the input gesture with respect to a user more effectively.

  In addition, even when the input gesture is different depending on the application, the gesture and the process associated with the gesture are displayed on the recognition correction menu 81, so that the user can easily correct the input gesture.

  Further, the recognition correction menu 81 may be provided with options such as “new setting”. By selecting “New setting”, the user can also set a new menu corresponding to the input gesture (for example, the gesture trajectory 62). That is, the user can register a new gesture that is not registered as a gesture input in the gesture recognition unit 31.

<Second Embodiment>
In the first embodiment, options are presented to support user gesture input. However, it is also possible to present an input-enabled area to support user gesture input. For example, when the user performs a gesture on the display unit 11 in an area where the gesture cannot be input or in an area where the gesture input by the user does not correspond, an input enabled area is a function that displays an area where the gesture can be input. Next, the display function will be described.

  The configuration of the information processing terminal 1 is the same as that described with reference to FIGS. 1 to 3.

[Operation of information processing terminal]
FIG. 11 is a flowchart illustrating the inputable area display process. The inputable area display process is a process executed by the controller 21 in order to realize the inputable area display function described above.

  12 to 15 are diagrams showing display examples when the inputable area display process is executed. The processing of the flowchart of FIG. 11 will be described below with reference to FIG. 4 and FIGS. 12 to 15.

  In step S31, the gesture recognition unit 31 detects a gesture. Specifically, in FIG. 4, the gesture recognition unit 31 detects that a gesture is input with the finger 41 to the display unit 11.

  In step S32, the gesture recognition unit 31 determines whether the gesture is a recognizable gesture. If the detected gesture is not a recognizable gesture, NO is determined in step S32, and the process proceeds to step S33. Specifically, for example, when a tap input is performed with the finger 41 in an area where there is no process associated with the tap input, NO is determined in step S32.

  In step S33, the recognition result correction unit 32 counts the number of input times of unrecognizable gestures. For example, the number of tap inputs performed by the finger 41 is counted in an area where there is no process associated with the tap input described above.

  In step S34, the recognition result correction unit 32 determines whether the unrecognizable gesture has been counted N times consecutively. N is an arbitrary integer. If it is determined as NO in step S34, that is, if an unrecognizable gesture has not been detected continuously N times, the process returns to step S31. In other words, the process of steps S31 to S34 is repeated until a recognizable gesture is not detected (the process of step S32) until an unrecognizable gesture is detected N times consecutively. If an unrecognizable gesture is detected N times consecutively, YES is determined in step S34, and the process proceeds to step S35.

  In step S <b> 35, the recognition result correction unit 32 displays the gesture input available areas 121 to 124. That is, the correction candidate generation unit 35 detects a gesture input available area where a gesture can be input at a predetermined time for each screen. In the example of FIG. 12, gesture input available areas 121 to 124 are detected. The recognition result correction unit 32 displays the gesture input available areas 121 to 124 on the display unit 11 based on the detection result. The gesture input available areas 121 to 124 are expressed as overlapping filters with different colors on the original display screen, for example. In other words, the gesture input available areas 121 to 124 allow the user to visually recognize the input possible area after allowing the original display screen (for example, characters, graphics, etc.) to be visible.

  For example, the gesture input enabled area 121 is an area in which tap input is possible within the range illustrated. The gesture input enabled area 122 is an area in which vertical flick (hereinafter referred to as vertical flick) input is possible within the range shown in the drawing. The gesture input enabled area 123 is an area in which a horizontal flick (hereinafter referred to as a horizontal flick) input is possible within the range shown in the drawing. The gesture input enabled area 124 is an area where the user can make a long press input while keeping the finger 41 in contact with the touch panel 25 for a certain period of time within the range shown in the figure. The user can know the type and position of a gesture that can be input from the color and position of the area.

  Next, in step S36, the recognition result correction unit 32 determines whether the help icon 101 has been tapped. That is, as shown in FIG. 13, when the help icon 101 is tapped with the finger 41, it is determined as YES in Step S36, and the process proceeds to Step S37.

  In step S37, the recognition result correction unit 32 displays the legend display screen 131. In other words, the correction candidate generation unit 35 generates an image to be displayed when a predetermined area is operated for each screen. Corresponding to the help icon 101, a legend display screen 131 shown in FIG. 14 is generated. Therefore, the recognition result correction unit 32 displays the legend display screen 131 on the display unit 11.

  As shown in FIG. 14, the legend display screen 131 is a screen that displays input gestures corresponding to the areas indicated by the gesture input available areas 121 to 124. As described above, for example, since the gesture input enabled area 121 is an area where tap input is possible, the legend display screen 131 exemplifies the color 121A of the gesture input enabled area 121, and “tap” is displayed correspondingly. Characters are displayed. Similarly, on the legend display screen 131, the colors 122A to 124A of the gesture input available areas 122 to 124 are exemplified, and the characters “vertical flick”, “horizontal flick”, and “long press” are displayed corresponding to the colors 122A to 124A, respectively. ing.

  In this manner, the user can understand which gesture input areas 121 to 124 can be input by looking at the legend display screen 131.

  Furthermore, an additional icon 125 that is operated when displaying supplementary information is displayed on the legend display screen 131. Since this additional icon 125 is also an icon to be tapped, it is displayed in the same color 121 </ b> A as the gesture input available area 121.

  In step S38, the recognition result correction unit 32 determines whether the additional icon 125 has been tapped. That is, as shown in FIG. 15, when the additional icon 125 is tapped with the finger 41, it is determined as YES in Step S38, and the process proceeds to Step S39.

  In step S39, the recognition result correction unit 32 displays the additional legend display screen 141. In other words, as described above, the correction candidate generation unit 35 generates the additional legend display screen 141 as a display image when the additional icon 125 is tapped. The recognition result correction unit 32 displays this on the display unit 11. Then, the process returns to step S31.

  The additional legend display screen 141 is a screen for displaying gestures that can be recognized on the current display screen, as shown in FIG. Specifically, in the additional legend display screen 141, as a process in which a gesture that draws a circle clockwise with the finger 41 (hereinafter referred to as a gesture (right rotation)) and a gesture (right rotation) are associated, “Rotate” is displayed. “Right rotation” is a process of rotating a figure or the like in the right direction. In addition, for example, a character “left rotation” is displayed as a process in which a gesture of drawing a circle counterclockwise with the finger 41 (hereinafter referred to as a gesture (left rotation)) and a gesture (left rotation) are associated with each other. “Rotate left” is, for example, a process of rotating a figure or the like in the left direction. In addition, in the additional legend display screen 141, the gesture (star), the gesture (triangle), and the gesture (W) described with reference to FIG. , “Close window” are displayed in association with each other.

  The user can know more inputable gestures as supplementary information by referring to the additional legend display screen 141.

  On the other hand, if NO is determined in step S36, that is, if the user does not tap the help icon 101, the user does not need the legend display screen 131. Therefore, the process returns to step S31. Similarly, if NO is determined in step S38, that is, if the user does not tap the additional icon 125, the user does not need the additional legend display screen 141, and the process returns to step S31.

  The case where it is determined as NO in step S32 has been described above. On the other hand, if YES is determined in step S32, that is, if the detected gesture is a recognizable gesture, the process proceeds to step S40. That is, if it is determined as YES in step S32, it is not necessary to display the gesture input available areas 121 to 124, and therefore the processing of steps S33 to S39 is not executed.

  In step S <b> 40, the gesture recognition unit 31 executes a process associated with the gesture. That is, when an unrecognizable gesture is detected N times consecutively (step S34), the gesture input available areas 121 to 124 are displayed (step S35), the legend display screen 131 and the additional legend display screen. 141 is displayed (processing in steps S37 and S39). If it is possible to input a gesture that can be recognized by the user by referring to these displays (steps S31 and S32), the process proceeds to step S40, and the gesture recognition unit 31 executes a process associated with the gesture. can do.

  By executing the inputable area display process in this way, the user can visually recognize the area in which gesture input is possible in association with the inputable gesture. Thereby, the user can correct | amend the gesture which he performed efficiently, and can perform the intended process.

  Further, even when the gesture input and the input possible area differ depending on the application, the input possible area corresponding to the gesture input is displayed on the legend display screen 131, so that the user can easily correct the input gesture.

  The series of processes described above can be executed by hardware or can be executed by software. When a series of processing is executed by software, a program constituting the software is installed in the computer. Here, for example, a general-purpose personal computer capable of executing various functions by installing a computer incorporated in the information processing terminal 1 as dedicated hardware or installing various programs.
