Abstract: Provided is a method of performing an input operation through motion recognition in a glasses-type display device, which is capable of controlling the glasses-type display device through the most natural and intuitive hand motion. The method of performing the input operation through motion recognition in the glasses-type display device includes: an image acquiring operation of acquiring sequential images by using a camera mounted on the glasses-type display device; a hand recognizing operation of recognizing a hand of a user from the acquired sequential images; a hand tracking operation of tracking the recognized hand; a hand motion recognizing operation of recognizing a motion of the hand based on a position of the hand acquired in the hand tracking operation; and a control signal outputting operation of outputting a control signal corresponding to the motion of the hand.

Abstract: Provided is a new type of virtual mouse driving method which is independent from individual skin color and capable of being implemented in general environments having a certain degree of disturbance. The virtual mouse driving method according to the invention in which a method of driving the virtual mouse is controlled by a change of hand shape includes an input step of receiving a plurality of images captured by an imaging camera at mutually different time points, a difference image extracting step of extracting a difference image among a plurality of images, and a virtual mouse driving step based on the extracted difference image.
