Abstract

A food texture presentation apparatus of the present embodiment includes a force stimulation presentation unit, a vibration stimulation presentation unit, and a temperature stimulation presentation unit that present different kinds of haptic stimuli in the oral cavity, a selection unit that selects a haptic stimulus to be presented, according to the food texture, and a force stimulation controller, a vibration stimulation controller, and a temperature stimulation controller that control respectively the force stimulation presentation unit, the vibration stimulation presentation unit, and the temperature stimulation presentation unit that present the selected haptic stimulus.

First claim

The invention claimed is:

1. A food texture presentation apparatus comprising: a plurality of presentation units configured to present different kinds of haptic stimuli in an oral cavity; a selection unit, including one or more processors, configured to select one of the haptic stimuli according to a food texture to be presented; and a controller configured to control a presentation unit of the plurality of presentation units corresponding to the selected one of the haptic stimuli.

2. The food texture presentation apparatus according to claim 1 , wherein the haptic stimuli include a force, a vibration, and a temperature.

3. The food texture presentation apparatus according to claim 1 , wherein the food texture presentation apparatus holds a parameter to present the food texture for each of the haptic stimuli, and
the selection unit is configured to select, from among the haptic stimuli, a haptic stimulus where a value of the parameter deviates from a predetermined value.

4. The food texture presentation apparatus according to claim 1 , wherein the selection unit is configured to select the one of the haptic stimuli based on onomatopoeia of the food texture to be presented.

5. A food texture presentation method of presenting a food texture by using a plurality of presentation units configured to present different kinds of haptic stimuli in an oral cavity, the food texture presentation method comprising: selecting, by a computer, one of the haptic stimuli according to the food texture to be presented; and controlling, by the computer, a presentation unit of the plurality of presentation units corresponding to the selected one of the haptic stimuli.

6. The food texture presentation method according to claim 5 , wherein the haptic stimuli include a force, a vibration, and a temperature.

7. The food texture presentation method according to claim 5 , wherein a parameter is held to present the food texture for each of the haptic stimuli, and
the food texture presentation method comprising:
selecting, from among the haptic stimuli, a haptic stimulus where a value of the parameter deviates from a predetermined value.

8. The food texture presentation method according to claim 5 , comprising:
selecting the one of the haptic stimuli based on onomatopoeia of the food texture to be presented.

9. A non-transitory computer readable medium storing one or more instructions causing a computer to present a food texture by using a plurality of presentation units configured to present different kinds of haptic stimuli in an oral cavity, the one or more instructions causing the computer to execute: selecting one of the haptic stimuli according to the food texture to be presented; and controlling a presentation unit of the plurality of presentation units corresponding to the selected one of the haptic stimuli.

10. The non-transitory computer readable medium according to claim 9 , wherein the haptic stimuli include a force, a vibration, and a temperature.

11. The non-transitory computer readable medium according to claim 9 , wherein a parameter is held to present the food texture for each of the haptic stimuli, and
wherein the one or more instructions cause the computer to execute:
selecting, from among the haptic stimuli, a haptic stimulus where a value of the parameter deviates from a predetermined value.

12. The non-transitory computer readable medium according to claim 9 , wherein the one or more instructions cause the computer to execute:
selecting the one of the haptic stimuli based on onomatopoeia of the food texture to be presented.
