Input terminal device and operation input method
This input terminal device 1 for receiving a user operation via a position input object PS is provided with: a position detection unit 106 which detects the position of the position input object; a display unit 109 a which displays a cursor; and an operation processing control unit 1024 which causes operation processing to be performed. The operation processing control unit has a plurality of operation modes and one of these modes includes a state M 0 in which the operation processing control unit does not cause any operation processing to be performed, except for movement of the cursor in accordance with the position of the position input object. The operation processing control unit is configured to switch between the plurality of operation modes when the user has performed a specific operation by means of the position input object.
1. An input terminal for inputting an operation of a user through a position input object, the input terminal comprising:
a 3D position detector configured to three-dimensionally detect a position, which includes x-position, y-position and z-position, of the position input object operated by the user;
a display configured to display a cursor on the basis of the x-position and the y-position detected by the 3D position detector; and
an operation processing controller configured to execute a corresponding operation process on the basis of the z-position detected by the 3D position detector,
wherein the operation processing controller has a plurality of operation modes related to execution of the operation process, and one of the operation modes has a state in which only movement of the cursor is executed according to the position of the position input object,
wherein the operation processing controller is configured to switch between the plurality of operation modes according to a length of time during which the z-position of the position input object is held within a predetermined range in an area in which the position input object can be detected under a situation that the movement of the cursor is executed according to the position of the position input object.
2. The input terminal according to claim 1 ,
wherein the operation processing controller is configured to change a shape and/or a color of the cursor displayed on the display depending on the operation modes.
3. The input terminal according to claim 1 ,
wherein the plurality of operation modes includes a first operation mode in which movement of the cursor on the display and process of drawing on the display are performed according to movement of the position detected by the 3D position detector and a second operation mode in which only movement of the cursor on the display is performed according to movement of the position detected by the 3D position detector.
4. The input terminal according to claim 1 ,
wherein the operation processing controller is configured to display a process instruction button on the display, and execute a process corresponding to the process instruction button when a position of the cursor is held at a position at which the process instruction button is displayed within a predetermined range for a predetermined time or more.
5. The input terminal according to claim 1 ,
wherein the operation processing controller is configured to execute a mouse operation process corresponding to the operation modes when the z-position of the position input object is within a predetermined range.
6. The input terminal according to claim 1 ,
wherein the x-position and the y-position are aligned in parallel and the z-position is aligned in vertical with respect to a surface of the display, and
the operation processing controller is configured to switch a plurality of screens for operation displayed on the display according to a plurality of ranges of the z-position detected by the 3D position detector.
7. The input terminal according to claim 6 ,
wherein the operation processing controller is further configured to set a transition region at a boundary between the plurality of ranges, and
when the z-position is within the transition region, a background of the screen for operation is changed and the screen for operation is continuously displayed on the display.
8. An operation input method of inputting an operation of a user through a position input object, the operation input method comprising:
a 3D position detection step of three-dimensional detecting a position, which includes x-position, y-position and z-position, of the position input object operated by the user;
a display step of displaying a cursor on a display on the basis of the x-position and the y-position detected in the 3D position detection step; and
an operation process step of executing a corresponding operation process on the basis of the position detected in the 3D position detection step,
wherein the operation process step has a plurality of operation modes related to execution of the operation process, and one of the operation modes has a state in which only movement of the cursor is executed according to the position of the position input object, and
wherein the operation process step switches between the plurality of operation modes when the user performs a specific operation through the position input object according to a length of time during which the z-position of the position input object is held within a predetermined range in an area in which the position input object can be detected under a situation that the movement of the cursor is executed according to the position of the position input object.
9. The operation input method according to claim 8 ,
wherein the plurality of operation modes includes a first operation mode in which movement of the cursor on the display and process of drawing on the display are performed according to movement of the position detected in the 3D position detection step and a second operation mode in which only movement of the cursor on the display is performed according to movement of the position detected by the 3D position detection step.
