1. Field of the Invention
The present invention relates to a tactile information conversion device, a tactile information conversion method, and a tactile information conversion program.
2. Description of the Related Art
In the related art, tactile sensation presentation devices have been developed that present a tactile sensation for a real or virtual object to a user.
For example, Patent Document 1 discloses a pen-type force sensation presentation device that presents, by allowing for motions such as a reciprocating motion, a swinging motion, a tilting motion, a rotation, and the like at a movable part where a fingertip touches when a user holds the device, proprioception to the fingertip.
