Input device, input support method, and program
View Patent ↗An input device includes a display unit which displays data on a screen, a proximity detection unit which detects proximity of a finger to the screen and outputs a proximity detection signal, a manipulation judging unit which discriminates between a valid manipulation and a return manipulation of successive movement manipulations of the finger on the basis of proximity detection signals in accordance with the successive movement manipulations of the proximity detected finger, and a control unit which invalidates proximity detection signals corresponding to the discriminated return manipulation.
1. An input device, comprising:
a display that displays contents on a screen;
a detector that detects an indicator and a hover slide performed by the detected indicator, the hover slide being a movement of the indicator substantially parallel to the screen without contacting the screen;
a judging processor that judges whether the detected hover slide indicates a valid contactless manipulation from a starting position or a return contactless manipulation which is performed after the valid contactless manipulation to return the indicator to a substantially same position as the starting position, and
a controller that controls the display so that,
when the valid manipulation is judged to be indicated by the hover slide, the display displays the contents by performing an operation assigned to the hover slide, and
when the return manipulation is judged to be indicated by the hover slide, the display displays the contents without performing the operation assigned to the hover slide,
wherein the judging processor discriminates between the hover slide indicating the valid manipulation and the hover slide indicating the return manipulation, based on a speed of the movement of the indicator.
2. The input device according to claim 1 ,
wherein the judging processor discriminates between the hover slide indicating the valid manipulation and the hover slide indicating the return manipulation, also based on a distance between the indicator and the screen.
3. The input device according to claim 2 ,
wherein the judging processor judges the hover slide indicates the return manipulation when the distance is larger than a predetermined threshold.
4. The input device according to claim 1 ,
wherein the judging processor judges the hover slide indicates the return manipulation when the speed is faster than a predetermined threshold.
5. An input device, comprising:
a display that displays contents on a screen;
a detector that detects an indicator and, at least one of a hover slide performed by the detected indicator and a contact to the screen performed by the detected indicator, the hover slide being a movement of the indicator substantially parallel to the screen without contacting the screen;
a judging processor that judges to ignore contact to the screen detected between a first contactless hover slide and a second contactless hover slide, when the contact meets a predetermined ignoring condition; and,
a controller that controls the display so that,
when the contact is judged to not be ignored, the display displays the content by performing an operation assigned to the first hover slide, an operation assigned to the contact and an operation assigned to the second hover slide, and
when the contact is judged to be ignored, the display displays the contents by performing an operation assigned to a successive hover slide without performing the operation assigned to the contact, the successive hover slide including the first hover slide and the second hover slide.
6. The input device according to claim 5 , the ignoring condition is at least one of:
a condition that a position of the contact is substantially on a locus on the screen corresponding to the second hover slide; and
a condition that a direction of the first hover slide and a direction of the second hover slide are opposite from each other and the position of the contact is substantially on a point on the screen corresponding to where the first hover slide ends and the second hover slide starts.
7. A method of controlling a display using an input device, comprising:
displaying contents on a screen of a display;
detecting, via the input device, an indicator and a hover slide performed by the detected indicator, the hover slide being a movement of the indicator substantially parallel to the screen without contacting the screen;
judging whether the detected hover slide indicates a valid contactless manipulation from a starting position or a contactless return manipulation which is performed after the valid contactless manipulation to return the indicator to a substantially same position as the starting position, and
controlling the display so that,
when the valid manipulation is judged to be indicated by the hover slide, the display displays the contents by performing an operation assigned to the hover slide, and
when the return manipulation is judged to be indicated by the hover slide, the display displays the contents without performing the operation assigned to the hover slide,
wherein the judging discriminates between the hover slide indicating the valid manipulation and the hover slide indicating the return manipulation, based on a speed of the movement of the indicator.
8. A tangible non-transitory computer readable storage medium that stores a computer program, the computer program, when executed by a processor of an input device, causing the input device to perform a process comprising:
displaying contents on a screen of a display;
detecting an indicator and a hover slide performed by the detected indicator, the hover slide being a movement of the indicator substantially parallel to the screen without contacting the screen;
judging whether the detected hover slide indicates a valid contactless manipulation from a starting position or a contactless return manipulation which is performed after the valid contactless manipulation to return the indicator to a substantially same position as the starting position, and
controlling the display so that,
when the valid manipulation is judged to be indicated by the hover slide, the display displays the contents by performing an operation assigned to the hover slide, and
when the return manipulation is judged to be indicated by the hover slide, the display displays the contents without performing the operation assigned to the hover slide,
wherein the judging discriminates between the hover slide indicating the valid manipulation and the hover slide indicating the return manipulation, based on a speed of the movement of the indicator.
9. A method of controlling a display using an input device, comprising:
displaying contents on a screen of a display;
detecting an indicator and at least one of a hover slide performed by the detected indicator and a contact to the screen performed by the detected indicator, the hover slide being a movement of the indicator substantially parallel to the screen without contacting the screen;
judging to ignore a contact detected between a first contactless hover slide and a second contactless hover slide, when the contact meets a predetermined ignoring condition; and,
controlling the display so that,
when the contact is judged to not be ignored, the display displays the content by performing an operation assigned to the first hover slide, an operation assigned to the contact and an operation assigned to the second hover slide, and
when the contact is judged to be ignored, the display displays the contents by performing an operation assigned to a successive hover slide without performing the operation assigned to the contact, the successive hover slide including the first hover slide and the second hover slide.
