A wearable camera that a user wears on a finger includes a release switch configured to switch to another state in response to an operation of the user, who is pointing an index finger at an object, with a thumb that is different from the index finger. Such switching of the release with the thumb enables the user to shoot an image of an object at a distant position. ## Claims ### Claim 1 A wearable device that a user wears on a finger, the wearable device comprising: a switch unit configured to switch to another state in response to an operation of the user, when a first finger is pointing at an object, with a second finger that is different from the first finger. ### Claim 2 (depends on 1) The wearable device according to claim 1, further comprising a functional unit configured to operate when the switch unit switches to the another state. ### Claim 3 (depends on 1) The wearable device according to claim 1, wherein the switch unit includes a first electrode to be put on the second finger of the user, and a second electrode to be put on one of the first finger or a third finger different from the second finger, and the switch unit switches to the another state in response to an operation of the user of the first electrode to come in contact with the second electrode. ### Claim 4 (depends on 1) The wearable device according to claim 1, wherein the switch unit includes an actuator to be put on the second finger of the user, and an action unit to be put on one of the first finger or a third finger different from the second finger, the action unit being configured to be activated by the actuator, and the switch unit switches to the another state in response to an operation of the user of the actuator to come close to or away from the action unit to activate the action unit. ### Claim 5 (depends on 3) The wearable device according to claim 3, wherein the second finger is a thumb. ### Claim 6 (depends on 2) The wearable device according to claim 2, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 7 (depends on 2) The wearable device according to claim 2, wherein the switch unit includes a first electrode to be put on the second finger of the user, and a second electrode to be put on one of the first finger or a third finger different from the second finger, and the switch unit switches to the another state in response to an operation of the user of the first electrode to come in contact with the second electrode. ### Claim 8 (depends on 2) The wearable device according to claim 2, wherein the switch unit includes an actuator to be put on the second finger of the user, and an action unit to be put on one of the first finger or a third finger different from the second finger, the action unit being configured to be activated by the actuator, and the switch unit switches to the another state in response to an operation of the user of the actuator to come close to or away from the action unit to activate the action unit. ### Claim 9 (depends on 4) The wearable device according to claim 4, wherein the second finger is a thumb. ### Claim 10 (depends on 3) The wearable device according to claim 3, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 11 (depends on 4) The wearable device according to claim 4, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 12 (depends on 5) The wearable device according to claim 5, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 13 (depends on 6) The wearable device according to claim 6, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 14 (depends on 7) The wearable device according to claim 7, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 15 (depends on 8) The wearable device according to claim 8, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector. ### Claim 16 (depends on 9) The wearable device according to claim 9, wherein the switch unit and the functional unit are separate units, and connect to each other via a connector.
