Claims13
A user interface device that interacts with a computer or a TV that realizes an electronic device, the user interface device comprising:
- a motion recognition module configured to recognize a motion of a user by using transmission and reception of an ultrasonic signal;
- and
- a battery configured to supply electric power to the motion recognition module,
- wherein the motion recognition module determines whether the ultrasonic signal reflected by a hand of the user and received is a preset reference value or higher, and sets the user interface device to any one of a general user interface mode or a motion recognition mode based on the determination result,
- wherein the motion recognition module transmits the ultrasonic signal to a space in which a hand of the user is located, and extracts a motion of the hand of the user based on the ultrasonic signal reflected by the hand of the user and received, and
- wherein the motion recognition module extracts the motion of the hand of the user, based on a shape of a widened V surface, of the shape of the hand of the user who uses the user interface device, between an index finger and a middle finger.
A mouse device that interacts with a computer or a TV that realizes an electronic device, the mouse device comprising:
- a motion recognition module configured to recognize a motion of a user by using transmission and reception of an ultrasonic signal;
- and
- a battery configured to supply electric power to the motion recognition module,
- wherein the motion recognition module is configured to:
- determine whether the ultrasonic signal reflected by a hand of the user and received is a preset reference value or higher, and sets the mouse device to any one of a general mouse mode or a motion recognition mode based on the determination result,
- transmit the ultrasonic signal to a space in which a hand of the user is located, and
- extract a motion of the hand of the user based on the ultrasonic signal reflected by the hand of the user and received, and
- wherein the motion recognition module extracts the motion of the hand of the user, based on a shape of a widened V surface, of the shape of the hand of the user who uses the user interface device, between an index finger and a middle finger.
