Abstract
A tactile sensation providing apparatus includes a touch sensor configured to detect a touch input, a load detection unit configured to detect a pressure load on a touch face of the touch sensor, a tactile sensation providing unit configured to vibrate the touch face, and a control unit configured to adjust a drive signal of the tactile sensation providing unit based on a pushed position when the pressure load detected by the load detection unit satisfies a standard to provide a tactile sensation.
Claims20
A tactile sensation providing apparatus comprising:
- a touch sensor configured to detect a touch input;
- a load detection unit configured to detect a pressure load on a touch face of the touch sensor, the touch face having a plurality of areas, at least some of which vary in size along at least one edge of the touch face;
- a tactile sensation providing unit configured to vibrate the touch face;
- and
- a control unit configured to adjust a drive signal of the tactile sensation providing unit based on a pushed position when the pressure load detected by the load detection unit satisfies a standard, to provide, based on adjustment information set for each of the plurality of areas, a same tactile sensation to an object applying the pressure load on the touch face independent of which of the areas includes the pushed position at which the object applies the pressure load.
A control method for a tactile sensation providing apparatus including
- a touch sensor configured to detect a touch input,
- a load detection unit configured to detect a pressure load on a touch face of the touch sensor, the touch face having a plurality of areas, at least some of which vary in size along at least one edge of the touch face, and
- a tactile sensation providing unit configured to vibrate the touch face, the control method comprising
- adjusting a drive signal of the tactile sensation providing unit based on a pushed position when the pressure load detected by the load detection unit satisfies a standard, to provide, based on adjustment information set for each of the plurality of areas, a same tactile sensation to an object applying the pressure load on the touch face independent of which of the areas includes the pushed position at which the object applies the pressure load.
A tactile sensation providing apparatus comprising:
- a touch sensor configured to detect a touch input;
- a piezoelectric element mounted on the touch sensor;
- and
- a control unit configured to detect a pressure load on a touch face of the touch sensor based on an output signal of the piezoelectric element, the touch face having a plurality of areas, at least some of which vary in size along at least one edge of the touch face, and, when the pressure load detected satisfies a standard, to provide, based on adjustment information set for each of the plurality of areas, a same tactile sensation to an object applying the pressure load on the touch face independent of which of the areas includes the pushed position at which the object applies the pressure load, by adjusting a drive signal of the piezoelectric element based on a pushed position.
A control method for a tactile sensation providing apparatus including
- a touch sensor configured to detect a touch input, and
- a piezoelectric element mounted on the touch sensor, the control method comprising detecting a pressure load on a touch face of the touch sensor based on an output signal of the piezoelectric element, the touch face having a plurality of areas, at least some of which vary in size along at least one edge of the touch face, and, when the pressure load detected satisfies a standard, to provide, based on adjustment information set for each of the plurality of areas, a same tactile sensation to an object applying the pressure load on the touch face independent of which of the areas includes the pushed position at which the object applies the pressure load, by adjusting a drive signal of the piezoelectric element based on a pushed position.
