Description

  The present invention relates to an input system, an input method, and an input program for performing input to an electronic device according to an operator's gesture.

  The spread of networks using the Internet has made it possible to easily obtain information and goods necessary for daily life. The rapid spread of personal computers has greatly contributed to the construction of such networks. However, as the application range of personal computers has gradually expanded, various demands have arisen for interface input devices, and it has not been possible to sufficiently meet these demands using only a keyboard and a mouse.

  Therefore, in recent years, touch panels that are portable and easy to operate and that allow handwritten character input have been used as input interface devices. As a method for realizing the touch panel, there are a resistive film method, an optical method, a capacitance method, an ultrasonic method, a pressure method, and the like, and various methods are employed depending on the application. For example, a public facility such as a station or a library employs a method that does not break even if it is handled roughly. In-vehicle navigation systems use a system that is durable against vibration and external light, and mobile terminals use a light and thin system.

  Among these methods, capacitive touch panels are rapidly spreading due to the explosive spread of smartphones. An input interface using such a touch panel is used integrally with a display device. In many cases, a liquid crystal display (LCD) is mainly used as the display device.

  When an input to an electronic device is performed using a touch panel, due to its nature, a finger, a hand, a pen, or the like that changes the capacitance or resistance needs to exist directly on the touch panel, or close to the touch panel. Thus, in the input method using a touch panel, since it is necessary to touch a touch panel directly, an operator's finger | toe, a hand, the touch-panel pen, etc. needed to exist in the very near range of an input device. In addition, the input method using the touch panel has a drawback in that the touch screen touches the display screen with dirt or scratches on the fingertip.

  By the way, an optical or wireless remote controller is known as a general method for inputting to an electronic device located at a distance, but is sufficient from the viewpoint of GUI (Graphical User Interface) compatibility. I could not say.

  As an input method for improving these, an input method using an image recognition technique using a camera system has been put into practical use. Specifically, an input method in which an input to a device located at a location away from the operator is performed by capturing the movement of the operator has been put into practical use, and this input method is generally called a gesture input.

  Patent Document 1 describes an apparatus that processes an operation input by a gesture. In the apparatus described in Patent Document 1, a user instruction point is extracted from an image obtained by photographing a user gesture performed while looking at a display, and a distance in the depth direction to the instruction point is obtained to obtain a parameter related to detection sensitivity. By adjusting, the operation input by the user's gesture is recognized.

  Patent Document 2 describes a presentation system that performs a presentation using a large-screen display device. In the system described in Patent Document 2, a presenter wearing a plurality of motion capture markers is photographed, a position on the displayed screen corresponding to the photographed image is obtained, and further, based on the photographed image. A predetermined operation is instructed.

JP 2012-137899 A JP 2011-70368 A

  As described in Patent Document 1 and Patent Document 2, there are various methods for gesture input. Specifically, in the methods described in Patent Document 1 and Patent Document 2, an operator is specified using a camera, and a cursor operation by a gesture is possible by projecting the operator's movement onto a cursor on the screen. I have to. The cursor is sometimes referred to as a pointer.

  When these input methods are used, the operator is away from the operating device, so that the operator can be captured by the camera according to the distance from the operator and the size of the projected screen. The cursor reflecting the movement of the image is projected on the screen at a certain ratio. This restricts the cursor from protruding from the screen by the operator's gesture.

  On the other hand, when such a restriction is performed, there is a difference between the amount of movement made by the operator's gesture and the amount of movement of the cursor, so it is difficult to perform the gesture so as to point to a specific place on the screen. Usually, the screen and the operator are separated from each other to some extent, and it is not easy to stop the cursor at the target location because it is necessary to perform delicate control operations to aim at a specific location on the screen from a distance. There is no problem. In particular, it is difficult for a physically handicapped person with a disability in the upper limbs to perform a fine gesture such as moving a cursor to a target location, and to use a general gesture input as an input method.

  Therefore, the present invention provides an input system and an input system that can easily move the cursor to the position when the input operation is performed by moving the cursor to a predetermined position on the screen according to the gesture of the operator. It is an object to provide a method and an input program.

  The input system according to the present invention includes an input area display means for displaying one or more input areas for inputting an operation instruction for a device on the screen, and a cursor at a position on the screen corresponding to the operation according to the operation of the operator. Cursor display means for displaying, a movement locus detection means for detecting the movement locus of the cursor, an enlarged area calculation means for calculating an enlarged area that is an enlarged area of the input area, and a cursor displayed on the screen An execution means for executing an action defined in the input area when the area is within the area, and the movement locus detection means detects an input locus that is a locus until the cursor reaches the input area, and calculates an enlarged region. After the cursor reaches the input area, the means calculates an area obtained by enlarging the input area in the moving direction indicated by the input locus as an enlarged area. When in, and executes the operations defined before the input region to be enlarged in the enlarged region.

  At this time, the movement trajectory detection means detects an intra-area trajectory that is the trajectory of the cursor in the enlarged area, and the input area display means stops after the cursor passes through the input area, and the intra-area trajectory stops in the enlarged area. In some cases, the enlarged area may be displayed.

  In addition, when the movement trajectory detecting means detects an in-area trajectory that is a trajectory of the cursor in the enlarged area, and the cursor display means stops after the cursor passes through the input area, the intra-area trajectory stops in the enlarged area. The cursor may be moved within the input area for display.

  In the input method according to the present invention, one or more input areas for inputting operation instructions to the device are displayed on the screen, and a cursor is displayed at the position of the screen corresponding to the operation according to the operation of the operator. Detects the input trajectory that is the trajectory until the cursor reaches the area, and after the cursor reaches the input area, calculates the enlarged area that is the area that has been enlarged in the moving direction indicated by the input trajectory. When the cursor displayed on the screen is in the enlargement area, the operation defined in the input area before the enlargement to the enlargement area is executed.

  An input program according to the present invention includes an input area display process for displaying one or more input areas for inputting an operation instruction for an apparatus on a computer, and a screen corresponding to the operation according to the operation of the operator. Cursor display processing for displaying a cursor at a position, movement trajectory detection processing for detecting the movement trajectory of the cursor, enlarged region calculation processing for calculating an enlarged region that is an enlarged input region, and a cursor displayed on the screen When the is in the input area, the execution process that executes the operation defined in the input area is executed, and the input locus that is the locus until the cursor reaches the input area is detected by the movement locus detection process. In the area calculation process, after the cursor reaches the input area, the area obtained by enlarging the input area in the movement direction indicated by the input locus is calculated and executed. In sense, if the cursor is in the enlarged area, characterized in that to perform the operations defined before the input region to be enlarged in the enlarged region.

  According to the present invention, when an input operation is performed by moving a cursor to a predetermined position on the screen according to an operator's gesture, the cursor can be easily moved to that position.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an explanatory diagram showing a configuration example of an embodiment of an input system according to the present invention. The input system of the present embodiment includes a cursor display unit 11, a movement locus detection unit 12, an input area display unit 13, an execution unit 14, and an enlarged area calculation unit 15.

  The cursor display unit 11 displays the cursor 30 at a position on the screen 10 corresponding to the operation of the operator 40. In addition, the method by which the cursor display unit 11 detects the operation of the operator 40 and the method for specifying the corresponding position on the screen are arbitrary.

  For example, when the operator 40 can attach a motion capture marker, the cursor display unit 11 may detect the operation of the operator 40 by the motion capture marker. Then, the cursor display unit 11 may previously define a position on the screen 10 where the cursor 30 is displayed according to the operation range to be detected, and display the cursor 30 on the screen 10 according to the detected operation.

  As a method used for motion capture, an arbitrary method such as an optical method, a mechanical method, or a magnetic method can be used. Further, the device used when detecting the operation of the operator 40 is not limited to the motion capture marker, and an arbitrary sensor may be used as a device for detecting the operation of the operator.

  In addition, for example, when an imaging device (not shown) that captures the motion of the operator 40 from the front can be used, the cursor display unit 11 uses a predetermined part (for example, a hand) from the image captured by the operator 40. The movement of the operator 40 may be detected by specifying the position. The cursor display means 11 defines in advance the position on the screen 10 where the cursor 30 is displayed according to the range to be imaged, and displays the cursor 30 on the screen 10 according to the operation of the part detected from the captured image. Also good.

  In addition, since the method of displaying the cursor 30 on the screen 10 according to the operation | movement of the operator 40 is widely known, detailed description is abbreviate | omitted.

  The input area display means 13 displays an area (hereinafter referred to as an input area 20) for inputting an operation instruction for the device on the screen 10. In the example shown in FIG. 1, one input area 20 is displayed, but the number of input areas 20 is not limited to one and may be two or more. The position of the input area 20 displayed on the screen 10 in the initial state and the operation defined for the input area 20 are determined in advance by, for example, an administrator. Examples of operations performed by the device include display screen transition processing and selection content determination processing, but operations performed by the device are not limited to these operations. The operations defined in each input area 20 may be the same or different.

  Further, the input area display means 13 displays the input area 20 in an enlarged manner in the moving direction of the cursor 30 detected by the movement locus detection means 12 described later. Hereinafter, an area obtained by enlarging the input area is referred to as an enlarged area. Here, the enlarged area not only means an area when displayed on the screen, but also means an area calculated from the input area 20 and not displayed.

  The input area display means 13 may display the enlarged contents of the input area 20 as an enlarged area. Further, the input area display means 13 may display only a frame indicating the enlarged area. However, the method for displaying the enlarged region is not limited to these contents. The input area display unit 13 may display the enlarged area using another method as long as the operator 40 can recognize the enlarged area of the input area 20.

  The movement locus detection means 12 detects the movement locus of the cursor 30 displayed on the screen 10 and collects the movement locus. Specifically, the movement trajectory detection unit 12 describes a trajectory until the cursor 30 reaches the input region 20 (hereinafter referred to as an input trajectory) and a trajectory of the cursor 30 in the enlarged region (hereinafter referred to as an intra-region trajectory). ) And collect each trajectory.

  The enlarged area calculation unit 15 calculates an area obtained by enlarging the input area (that is, an enlarged area). Specifically, after the cursor 30 reaches the input area 20, the enlarged area calculation unit 15 calculates an area obtained by enlarging the input area 20 in the moving direction indicated by the input locus as an enlarged area. A method for calculating the enlarged area will be described later.

  When the cursor 30 displayed on the screen 10 is in the input area 20, the execution means 14 executes an operation defined in the input area 20. The execution means 14 may execute the operation defined in the input area 20 when the movement of the cursor 30 stops in the input area 20. The execution means 14 may execute the operation defined in the input area 20 when the operator 30 receives a predetermined execution instruction after the cursor 30 stops in the input area 20.

  Furthermore, when the cursor 30 is present in the enlarged area calculated by the enlarged area calculating means 15, the executing means 14 may execute the operation defined in the input area 20 before the enlarged area is enlarged. . The timing for executing the operation is the same as when the cursor 30 is in the input area 20.

  In general, when gesture input is performed in order to move the cursor to an intended position, the cursor cannot often be stopped at the intended position due to a difference in distance, and the cursor often goes too far. FIG. 2 is an explanatory diagram illustrating an example of a general input operation. In FIG. 2, the locus of the cursor 30 is indicated by a broken line. As shown in FIG. 2, generally, even if an attempt is made to move the cursor 30 to a target position (input area 20) by gesture input, the cursor 30 may pass through that position. In this case, it is conceivable to perform a reverse gesture in an attempt to return the cursor in the reverse direction, but there is a possibility that the movement operation by the gesture will not be successful and the cursor will pass the target position. In this case, as shown in FIG. 2, in order to move the cursor to the target position, one and a half reciprocal operations are required.

  However, in the present embodiment, even when the input area display means 13 displays an enlarged area obtained by enlarging the input area 20 in the moving direction of the cursor 30, and the execution means 14 has the cursor 30 in the enlarged area, The operation defined in the input area 20 is executed. Therefore, even if the cursor 30 leaves the first input area 20, the operator 40 can complete the input operation without requiring an operation to return the cursor 30 that has gone too far.

  The execution means 14 may determine that the cursor 30 has stopped when it is detected that the cursor 30 exists at the same point for a preset period. Further, if the number of times of performing the recognition process of the position where the cursor 30 exists is counted, when the number of times the presence of the cursor 30 is detected exceeds a predetermined number, the execution means 14 It may be determined that the cursor 30 has stopped.

  Next, a method for calculating the enlarged area will be described. The enlargement area calculation means 15 analyzes the locus (input locus) until the cursor 30 reaches the input area 20, and enlarges the area in the extension line direction of the locus. At this time, the enlargement area calculation unit 15 may determine a direction in which the movement direction of the cursor 30 is decomposed into the x-axis direction and the y-axis direction of the screen and enlarged.

  For example, when the cursor 30 has moved in the positive direction of the x axis (right direction) and the positive direction of the y axis (upward direction), the enlarged region calculation means 15 is positioned at the leftmost position in the x axis direction in the input region 20. And the lowest position in the y-axis direction may be fixed, and the input area 20 may be enlarged in the positive direction of the x-axis and the positive direction of the y-axis, respectively. On the other hand, when the cursor 30 is moving in the negative x-axis direction (leftward) and the negative y-axis direction (downward), the enlarged region calculation means 15 is the rightmost in the input region 20 in the x-axis direction. The position and the uppermost position in the y-axis direction may be fixed, and the input area 20 may be enlarged in the negative direction of the x-axis and the negative direction of the y-axis, respectively. Further, the enlargement area calculation means 15 may enlarge the input area 20 equally, or may change the enlargement ratio according to the ratio of the movement amount in the x-axis direction and the y-axis direction.

  The enlargement width of the input area 20 is changed depending on the size of the gesture (gesture amplitude) performed by the operator and the ratio of the cursor movement amount (cursor amplitude) projected on the screen. However, considering that the burden is not imposed on the operator, the expansion width of the input area is not a burden on the movement of the operator, and is equal to or less than the range of the arm length, preferably approximately 10 to 50 cm. Make the amount you want.

  Further, for example, a plurality of types of enlargement widths may be set on the system side, and the enlargement area calculation unit 15 may calculate the enlargement area using the enlargement width selected by the operator from these enlargement widths. .

  The input area display means 13 may display an enlarged area when the cursor 30 reaches the input area 20. The input area display means 13 may display an enlarged area when the cursor 30 moves out of the input area 20 after the cursor 30 reaches the input area 20. Further, the input area display means 13 may display the enlarged area when the cursor 30 passes through the input area 20 and the position where the cursor 30 stops after passing is within the range of the enlarged area. That is, the input area display means 13 may display the enlarged area when the intra-region trajectory stops in the enlarged area after the cursor 30 passes through the input area 20. In the following, a method for displaying an enlarged area when an intra-region trajectory stops in the enlarged area after the cursor 30 passes through the input area 20 will be described as an example.

  FIG. 3 is an explanatory diagram illustrating an example of displaying an enlarged area obtained by enlarging the input area. In the example illustrated in FIG. 3, it is assumed that the cursor 30 moves in the upper right direction along a locus indicated by a broken line. At this time, in the example shown in FIG. 3, the input locus L1 up to the input area 20 is detected by the movement locus detecting means 12, and the input area display means 13 sets the area in the upper right direction which is the extension line direction of the locus. It shows that the enlarged area 21 has been displayed.

  FIG. 4 is an explanatory diagram showing another example of displaying an enlarged area obtained by enlarging the input area. The example shown in FIG. 4 shows a case where the trajectory of the cursor 30 has overshot half a round trip. In this case, the input area display means 13 first displays the enlarged area 22. Thereafter, an operation for moving the cursor 30 in the reverse direction is performed, and when the cursor 30 is removed from the enlarged area 22, the input area display unit 13 cancels the enlargement process of the enlarged area 22. On the other hand, since the cursor 30 has passed through the input area 20 in the lower left direction, the input area display means 13 displays the enlarged area 23. Thereafter, when the cursor 30 moves out of the enlargement area 23, the input area display unit 13 cancels the enlargement process of the enlargement area 23. Thereafter, when an operation of returning the cursor 30 to the original input area 20 is performed, a normal input operation is performed.

  The cursor display means 11, the movement trajectory detection means 12, the input area display means 13, the execution means 14, and the enlarged area calculation means 15 are realized by a CPU of a computer that operates according to a program (input program). For example, the program is stored in a storage unit (not shown) of the terminal, and the CPU reads the program, and in accordance with the program, the cursor display means 11, the movement locus detection means 12, the input area display means 13, the execution means 14 and The enlargement area calculation unit 15 may operate. The cursor display means 11, the movement trajectory detection means 12, the input area display means 13, the execution means 14, and the enlarged area calculation means 15 may each be realized by dedicated hardware.

  Next, the operation of the input system of this embodiment will be described. FIG. 5 is a flowchart showing an operation example of the input system of this embodiment. In the initial state, it is assumed that the input area display means 13 displays the input area 20 in which the action is defined on the screen 10, and the operator 40 moves the cursor 30 to the input area 20 from this state. Shall be performed.

  First, the cursor display unit 11 detects the operation of the operator 40 and displays the cursor 30 at a corresponding position on the screen 10 (step S1). Thereafter, the cursor display unit 11 repeats the operation of moving and displaying the cursor 30 according to the operation of the operator. At that time, the movement trajectory detection means 12 collects a trajectory (that is, an input trajectory) until the cursor 30 moves to the input area 20 (step S2).

  The movement locus detection means 12 determines whether or not the cursor 30 has reached the input area 20 (step S3). When the cursor 30 has not reached the input area 20 (N in step S3), the movement trajectory detecting means 12 repeats the processing after step S2 for collecting the input trajectory.

  On the other hand, when the cursor 30 reaches the input area 20 (Y in step S3), the enlarged area calculation means 15 calculates an area obtained by enlarging the input area 20 in the moving direction indicated by the input locus as an enlarged area (step S4). ). Then, the movement trajectory detection means 12 collects the trajectory of the cursor 30 in the enlarged region (that is, the intra-region trajectory) (step S5).

  Thereafter, the execution means 14 determines whether or not the cursor 30 has stopped (step S6). When the cursor 30 stops (Y in step S6), the execution unit 14 further determines whether or not the cursor 30 has stopped in the enlarged region (step S7). When the cursor 30 stops in the enlargement area (Y in step S7), the input area display means 13 displays the enlargement area (step S8), and the execution means 14 displays the input area 20 before enlarging the enlargement area. The defined operation is executed (step S9).

  On the other hand, when it is determined in step S6 that the cursor 30 has not stopped (N in step S6), the movement trajectory detecting means 12 determines whether or not the cursor 30 has left the enlarged region (step S10). When the cursor 30 is not out of the enlarged region (N in step S10), the movement trajectory detecting means 12 repeats the processing from step S5 onward to collect the intra-region trajectory. On the other hand, when the cursor 30 deviates from the enlarged region (Y in step S10), the movement trajectory detection unit 12 repeats the processing after step S2 for collecting the input trajectory.

  As described above, according to the present embodiment, the cursor display unit 11 displays the cursor 30 at the position of the screen 10 corresponding to the operation of the operator 40, and the movement locus detection unit 12 A trajectory (input trajectory) until the cursor reaches the input area 20 is detected. Further, after the cursor 30 reaches the input area 20, the enlarged area calculation means 15 calculates an area obtained by enlarging the input area 20 in the moving direction indicated by the input locus as an enlarged area. Then, when the cursor 30 is in the enlargement area, the execution means 14 executes the operation defined in the input area 20 before being enlarged to the enlargement area.

  With the configuration described above, when an input operation is performed by moving the cursor to a predetermined position on the screen according to the gesture of the operator, the cursor can be easily moved to that position. That is, when a cursor operation is performed by a gesture input, the target cursor can be easily captured even when the cursor overshoots. Therefore, it is possible to easily input a gesture even for an operator who is unfamiliar with the operation or a disabled person.

  Further, in the present embodiment, the movement trajectory detection means 12 detects the cursor trajectory (intra-area trajectory) in the enlarged area, and the input area display means 13 passes through the input area 20 after the cursor 30 passes. When the locus stops within the enlarged area, the enlarged area is displayed. That is, when the cursor 30 passes through the input area 20 and further leaves the enlarged area, the enlarged area is not displayed. By doing in this way, it can suppress that the range which an operator does not intend is selected.

  Next, a modification of this embodiment will be described. In the above-described embodiment, the method in which the input area display unit 13 displays the enlarged area when the locus in the area stops in the enlarged area after the cursor 30 passes through the input area 20 has been described. In this modified example, when the locus in the area stops in the enlarged area after the cursor 30 passes through the input area 20, the enlarged area is not displayed, and the cursor display means 11 moves the cursor 30 to the original input area 20. Move to display.

  The position in the input area 20 where the cursor display means 11 moves the cursor 30 is arbitrary. For example, the cursor display unit 11 may move the cursor 30 to the center of the input area 20 or may move the cursor 30 to a location that has passed through the input area 20. Further, a position where the cursor 30 is moved to the input area 20 may be determined in advance.

  FIG. 6 is an explanatory diagram illustrating an example in which the cursor in the enlargement area is moved to the movement area. When the cursor 30 passes through the input area 20 and stops at the enlarged area 21, the cursor 30 is forcibly moved to the original input area 20. Thereafter, an input operation is performed by the operator. That is, in this modification, only the enlargement area is calculated, and only the movement of the cursor 30 is confirmed without displaying the enlargement area on the screen.

  FIG. 7 is a flowchart illustrating an operation example of a modification of the input system. In the flowchart illustrated in FIG. 7, the processes in steps S8 and S9 in the flowchart illustrated in FIG. 5 are replaced with steps S18 and S19. Hereinafter, only the parts different from the flowchart illustrated in FIG. 5 will be described with respect to the flowchart illustrated in FIG. 7.

  When the cursor 30 stops in the enlarged area (Y in step S7), the cursor display means 11 moves the cursor 30 to the input area 20 and displays it (step S18). And the execution means 14 performs the operation | movement defined in the input area 20 (step S19).

  As described above, according to the present modification, the movement trajectory detection means 12 detects the cursor trajectory (intra-area trajectory) in the enlarged area, and the cursor display means 11 passes the input area 20 by the cursor 30. Thereafter, when the intra-region trajectory stops in the enlarged region, the cursor is moved into the input region 20 and displayed. Also by doing in this way, it is possible to suppress selection of a range not intended by the operator as in the above embodiment.
