Abstract
An object of the present invention is to provide corresponding tactile sensations in accordance with a characteristic of an image displayed. Specifically, an electronic device 10 according to the present invention includes a display unit 102 configured to display an image, a touch sensor 103 configured to detect a touch, a tactile sensation providing unit 104 configured to provide the tactile sensation to a touch face of the touch sensor 103, and a control unit 109 configured to divide the image into a plurality of areas and, when the touch sensor detects the touch to a position corresponding to any of the plurality of areas, to control the tactile sensation providing unit 104 to provide the tactile sensation associated with the area.
Claims11
An electronic device comprising:
- a display unit configured to display an image;
- a touch sensor configured to detect a touch;
- a tactile sensation providing unit configured to provide a tactile sensation to a touch face of the touch sensor;
- and
- a control unit configured to divide the image into a plurality of areas, set tactile sensations each associated with the areas, wherein each tactile sensation is associated with a predetermined threshold based on a frequency spectrum of the image of each portion of an area such that the predetermined threshold of one area differing from the predetermined threshold of an another area,
- differentiation of the predetermined threshold of the one area as compared with the predetermined threshold of the another area is done by at least one of a manner of vibration and an intensity of vibration, and,
- when the touch sensor detects a touch to a position corresponding to any of the plurality of areas, to control the tactile sensation providing unit to provide the tactile sensation associated with the area and when the touch sensor detects a touch to a position corresponding to any of the plurality of areas and a data based on a pressing of the touch satisfies a predetermined threshold associated to each area, the control unit starts to control the tactile sensation providing unit to provide the tactile sensation associated with the area.
A control method of an electronic device having
- a display unit configured to display an image
- a touch sensor configured to detect a touch, and
- a tactile sensation providing unit configured to provide a tactile sensation to a touch face of the touch sensor, the control method comprising:
- dividing the image into a plurality of areas;
- controlling the tactile sensation providing unit, when a touch to a position corresponding to any of the plurality of areas at the touch sensor is detected, to provide the tactile sensation associated with the area and when the touch sensor detects a touch to a position corresponding to any of the plurality of areas and a data based on a pressing of the touch satisfies a predetermined threshold associated to each area, starts to control the tactile sensation providing unit to provide the tactile sensation associated with the area;
- dynamically setting the predetermined threshold based on a frequency spectrum of the image of each portion of an area, wherein the predetermined threshold of one area differs from the predetermined threshold of another area;
- and
- differentiating the predetermined threshold of the one area as compared with the redetermined threshold of the another area by at least one of a manner of vibration and an intensity of vibration.
