a controller that sets a base point of the second portion in response to the motion of the first portion and receives a prescribed input in response to the motion of the second portion with respect to the base point; and a notification device that contactlessly notifies a third portion of the body that the base point is set. ## Claims ### Claim 1 A system comprising: a sensor configured to detect a first motion of a first portion of a body of a user, and detect a second motion of a second portion of the body; a controller configured to set a base point at a position of the second portion at a timing when the first motion of the first portion is detected, and receive a prescribed input in response to the second motion of the second portion with respect to the base point; and a cutaneous notification device configured to contactlessly notify the second portion of the body that the base point is set at the position where the second portion exists at the timing. ### Claim 2 (depends on 1) The system according to claim 1, wherein the cutaneous notification device includes at least one selected from a group consisting of an ultrasonic vibrator, a laser, a Peltier element, an air cannon, and an infrared source. ### Claim 3 (depends on 1) The system according to claim 1, wherein the cutaneous notification device includes plural ultrasonic vibrators that provide an acoustic radiation pressure to the second portion. ### Claim 4 (depends on 1) The system according to claim 1, wherein the first portion and the second portion are the same portion of the body. ### Claim 5 (depends on 1) The system according to claim 1, wherein the cutaneous notification device is further configured to contactlessly notify the second portion that the prescribed input is received. ### Claim 6 (depends on 1) The system according to claim 1, wherein the controller is further configured to cancel the set base point in response to a third motion of the second portion. ### Claim 7 (depends on 1) The system according to claim 1, wherein the controller is further configured to acquire information of respective coordinate positions of the first portion and the second portion in a real space. ### Claim 8 A method comprising: detecting, using a sensor, a first motion of a first portion of a body of a user; setting, using a controller, a base point at a position of a second portion of the body at a timing when the first motion is detected; contactlessly notifying, using a cutaneous notification device, the second portion of the body that the base point is set at the position where the second portion exists at the timing; and receiving, using the sensor and the controller, a prescribed input in response to a second motion of the second portion with respect to the base point. ### Claim 9 (depends on 8) The method according to claim 8, wherein the first portion and the second portion are the same portion of the body. ### Claim 10 (depends on 8) The method according to claim 8, further comprising: contactlessly notifying the second portion that the prescribed input is received. ### Claim 11 (depends on 8) The method according to claim 8, further comprising: cancelling the base point in response to a third motion of the second portion. ### Claim 12 (depends on 8) The method according to claim 8, wherein the controller further acquires information of respective coordinate positions of the first portion and the second portion in a real space. ### Claim 13 (depends on 1) The system according to claim 1, wherein the controller is further configured to set a position of an object to receive the prescribed input in accordance with the set base point position, and the cutaneous notification device is further configured to contactlessly notify the second portion of the body at a timing when the second portion is positioned at the set position of the object. ### Claim 14 (depends on 6) The system according to claim 6, wherein the controller is further configured to, after the cancelling of the set base point, reset the base point position at a new position of the second portion at a new timing when the first motion of the first portion is detected again. ### Claim 15 (depends on 8) The method according to claim 8, further comprising: setting, using the controller, a position of an object for receiving the prescribed input in accordance with the set base point position; and contactlessly notifying, using the cutaneous notification device, the second portion of the body at a timing when the second portion is positioned at the set position of the object. ### Claim 16 (depends on 11) The method according to claim 11, further comprising: after the cancelling of the set base point, resetting, using the controller, the base point position at a new position of the second portion at a new timing when the first motion of the first portion is detected again.
