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

The invention claimed is:

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

2. The tactile stimulation presentation device according to claim 1 , wherein
the measurement unit is configured to transmit the first measurement of the first type of physical quantity with respect to the first human body to another tactile stimulation presentation device.

3. A tactile stimulation presentation method comprising:
measuring, by a measurement unit, a first measurement of a first type of physical quantity with respect to a tactile sensation applied to a first region of a first human body;
receiving, by a control unit, a second measurement of the first type of physical quantity applied to a second human body that is different from the first human body;
determining, by the control unit, a difference between the first measurement of the first type of physical quantity applied to the first human body and the second measurement of the first type of physical quantity applied to the second human body;
converting, by the control unit, the second measurement of the first type of physical quantity into a second physical quantity of a different type from the first type of physical quantity;
adjusting a magnitude of the second physical quantity based on the difference between the first measurement and the second measurement of the first type of physical quantity; and
applying, by a presentation unit, the second physical quantity to a second region of the first human body.

4. The tactile stimulation presentation method according to claim 3 , further comprising:
transmitting, by the measurement unit, the first measurement of the first type of physical quantity with respect to the first human body to another tactile stimulation presentation device.
