Abstract

To provide a structure capable of causing a user to perceive a desired tactile stimulus more reliably. A control device including: an information acquisition unit configured to obtain first information regarding a tactile stimulus transferred from a first tactile stimulus generation source and second information regarding a tactile stimulus which a user is caused to perceive; and a control unit configured to control output of a tactile stimulus of a second tactile stimulus generation source different from the first tactile stimulus generation source on a basis of the first information and the second information. Further, a control method using a processor and a computer system program.

First claim

1 . A control device comprising:
an information acquisition unit configured to obtain first information regarding a tactile stimulus transferred from a first tactile stimulus generation source and second information regarding a tactile stimulus which a user is caused to perceive; and a control unit configured to control output of a tactile stimulus of a second tactile stimulus generation source different from the first tactile stimulus generation source on a basis of the first information and the second information.

2 . The control device according to claim 1 ,
wherein the tactile stimulus includes tactile vibration, and the control unit controls output of third tactile vibration suppressing tactile vibration other than second tactile vibration related to the second information in first tactile vibration related to the first information with regard to the second tactile stimulus generation source.

3 . The control device according to claim 2 ,
wherein the second tactile vibration includes composite vibration of fourth tactile vibration output by a plurality of the second tactile stimulus generation sources, and the third tactile vibration includes tactile vibration suppressing tactile vibration other than the fourth tactile vibration.

4 . The control device according to claim 2 ,
wherein the third tactile vibration includes tactile vibration suppressing fifth tactile vibration output by the specific second tactile generation source among a plurality of the second tactile stimulus generation sources.

5 . The control device according to claim 4 ,
wherein amplitude of the tactile vibration suppressing the fifth tactile vibration includes amplitude less than amplitude of the fifth tactile vibration.

6 . The control device according to claim 2 ,
wherein the first tactile vibration includes detected tactile vibration.

7 . The control device according to claim 6 ,
wherein the first tactile vibration is detected by a tactile vibration measurement device.

8 . The control device according to claim 6 ,
wherein the second tactile stimulus generation source includes a tactile vibration generation device, and the first tactile vibration is detected on a basis of an electromotive force generated in the tactile vibration generation device due to tactile vibration received by the tactile vibration generation device.

9 . The control device according to claim 2 ,
wherein the first tactile vibration includes tactile vibration that is estimated to be generated.

10 . The control device according to claim 2 ,
wherein the third tactile vibration includes tactile vibration suppressing tactile vibration other than the second tactile vibration at a specific position in a transfer unit to which tactile vibration is transferred.

11 . The control device according to claim 10 ,
wherein the specific position includes a position coming into contact with the user.

12 . The control device according to claim 2 ,
wherein the control unit causes the second tactile vibration to the second tactile stimulus generation source to output the second tactile vibration.

13 . The control device according to claim 12 ,
wherein the control unit controls amplitude of the second tactile vibration on a basis of comparison between amplitude of the second tactile vibration in the first tactile vibration and target amplitude.

14 . The control device according to claim 12 ,
wherein the control unit controls whether the second tactile vibration is output on a basis of comparison between amplitude of the second tactile vibration in the first tactile vibration and target amplitude.

15 . The control device according to claim 2 ,
wherein the third tactile vibration includes tactile vibration suppressing tactile vibration with a specific frequency or amplitude in tactile vibration other than the second tactile vibration.

16 . The control device according to claim 15 ,
wherein the specific frequency or amplitude is decided on a basis of frequency or amplitude of the second tactile vibration.

17 . The control device according to claim 2 ,
wherein the control unit controls a form of the third tactile vibration on a basis of information regarding an environment around the user, information regarding a behavior of the user, or information regarding a nature or a form of a transfer unit to which tactile vibration is transferred.

18 . A control method comprising, by a processor:
obtaining first information regarding a tactile stimulus transferred from a first tactile stimulus generation source and second information regarding a tactile stimulus which a user is caused to perceive; and controlling output of a tactile stimulus of a second tactile stimulus generation source different from the first tactile stimulus generation source on a basis of the first information and the second information.

19 . A program causing a computer system to realize:
an information acquisition function of obtaining first information regarding a tactile stimulus transferred from a first tactile stimulus generation source and second information regarding a tactile stimulus which a user is caused to perceive; and a control function of controlling output of a tactile stimulus of a second tactile stimulus generation source different from the first tactile stimulus generation source on a basis of the first information and the second information.
