Abstract

A tactile stimulation presentation device 1 includes a measurement unit 11 configured to measure a first physical quantity with respect to a tactile sensation applied to a first region of a human body, a control unit 12 configured to convert the first physical quantity into a second physical quantity of a different type from the first physical quantity, and a presentation unit 13 configured to apply the second physical quantity to a second region different from the first region.

First claim

1 . A tactile stimulation presentation device comprising:
a measurement unit including one or more processors, configured to measure a first physical quantity with respect to a tactile sensation applied to a first region of a human body; a control unit including one or more processors, configured to convert the first physical quantity into a second physical quantity of a different type from the first physical quantity; and a presentation unit including one or more processors, configured to apply the second physical quantity to a second region different from the first region.

2 . The tactile stimulation presentation device according to claim 1 , wherein the human body is a first human body and a second human body different from each other, and wherein
the measurement unit is configured to transmit the first physical quantity with respect to the first human body to another tactile stimulation presentation device, and the presentation unit is configured to apply the second physical quantity converted from a first physical quantity with respect to the second human body received from the other tactile stimulation presentation device to the second region of the first human body.

3 . The tactile stimulation presentation device according to claim 2 , wherein
the control unit is configured to adjust a magnitude of the second physical quantity in response to a magnitude of a difference between the first physical quantity with respect to the first human body and the first physical quantity with respect to the second human body.

4 . A tactile stimulation presentation method comprising:
measuring, by a measurement unit, a first physical quantity with respect to a tactile sensation applied to a first region of a human body; converting, by a control unit, the first physical quantity into a second physical quantity of a different type from the first physical quantity; and applying, by a presentation unit, the second physical quantity to a second region different from the first region.

5 . The tactile stimulation presentation method according to claim 4 , wherein the human body is a first human body and a second human body is different from each other, and the method comprises:
transmitting, by the measurement unit, the first physical quantity with respect to the first human body to another tactile stimulation presentation device, and applying, by the presentation unit, the second physical quantity converted from a first physical quantity with respect to the second human body received from the other tactile stimulation presentation device to the second region of the first human body.

6 . The tactile stimulation presentation device according to claim 5 , further comprising:
adjusting, by the control unit, a magnitude of the second physical quantity in response to a magnitude of a difference between the first physical quantity with respect to the first human body and the first physical quantity with respect to the second human body.
