Abstract
There is provided a tactile sensation presenting device including a plurality of tactile sensation presenting units that presents a tactile sensation based on control information, and a control unit that generates the control information which is different for each of the plurality of tactile sensation presenting units, based on information which is generated by an operation tool and is related to contact between the operation tool and an object. The control unit further provides the control information to each of the plurality of tactile sensation presenting units.
Claims17
A tactile sensation presenting device, comprising:
- a plurality of tactile sensation presenting units;
- and
- a control unit configured to:
- receive information that includes
- a first frequency of vibration associated with an operation tool, and
- a first displacement amount of the vibration, wherein the received information is related to a first contact between the operation tool and an object;
