Wearable device for recognizing touch input by external object and method thereof

Abstract

A wearable device may obtain an image, while a screen is displayed, using a camera. The wearable device may identify a visual object corresponding to an external object from the image. The wearable device may display, at a first location of a portion of the visual object corresponding to a portion of the external object farther than a reference distance from a second surface, a pointer on the screen. The wearable device may recognize the external object contacted on the second surface according to movement from outside the reference distance, as a touch input at a second location identified based on a path of the movement and the first location, and provide feedback with respect to the touch input.
