Abstract

A tactile sensation presenting device includes: a vibrating element configured to present vibration information; a warmth/coldness presenting element provided above the vibrating element and configured to present warm/cold information to a tactile sensation presentation surface; a pressure detecting unit configured to detect a pressure corresponding to a contact state of an operating part with respect to the tactile sensation presentation surface; and an adjusting unit configured to adjust a presentation condition based on a detection result by the pressure detecting unit.

First claim

What is claimed is:

1 . A tactile sensation presenting device comprising:
a vibrating element configured to present vibration information;
a warmth/coldness presenting element provided above the vibrating element and configured to present warm/cold information to a tactile sensation presentation surface;
a pressure detecting unit configured to detect a pressure corresponding to a contact state of an operating part with respect to the tactile sensation presentation surface; and
an adjusting unit configured to adjust a presentation condition based on a detection result by the pressure detecting unit.

2 . The tactile sensation presenting device according to claim 1 , wherein the adjusting unit adjusts, as the presentation condition, at least one of the vibration information and the warm/cold information.

3 . The tactile sensation presenting device according to claim 2 , wherein the pressure detecting unit is provided on the tactile sensation presentation surface and detects the pressure received by the tactile sensation presentation surface from the operating part.

4 . The tactile sensation presenting device according to claim 2 further comprising:
a holding member configured to hold the operating part so as to maintain the contact state with respect to the tactile sensation presentation surface,
wherein the pressure detecting unit is provided on a contact surface where the holding member contacts the operating part, and detects a pressure received by the contact surface from the operating part.

5 . The tactile sensation presenting device according to claim 1 , wherein the adjusting unit adjusts, as the presentation condition, a pressure applied to the operating part contacting the tactile sensation presentation surface.

6 . The tactile sensation presenting device according to claim 5 , further comprising:
a holding member configured to hold the operating part so as to maintain the contact state with respect to the tactile sensation presentation surface; and a displacing unit configured to displace the tactile sensation presentation surface, wherein the adjusting unit causes the displacing unit to displace the tactile sensation presentation surface based on the detection result by the pressure detecting unit in order to adjust the pressure applied to the operating part held by the holding member.

7 . The tactile sensation presenting device according to claim 1 , wherein the pressure detecting unit is an electrostatic detecting unit configured to detect the pressure by a change in electrostatic capacity.

8 . The tactile sensation presenting device according to claim 1 , wherein the pressure detecting unit is a resistance type detecting unit configured to detect the pressure by a change in resistance value.
