APPARATUS FOR USER INTERFACE BASED ON WEARABLE COMPUTING ENVIRONMENT AND METHOD THEREOF

Provided is an apparatus for user interface based on wearable computing environment includes: a signal measurement unit including a plurality of image measurement units that includes image sensors each of which receives optical signals generated from a position indicator that is worn on user's fingers or near a user's wrist to generate optical signals and measures images of the user foreground; and a signal processor that analyzes each image measured by the signal measurement unit to measure three-dimensional coordinates, recognizes a motion pattern of the user's hand on the three-dimensional coordinates from the optical signals received by the signal measurement unit, and outputs the corresponding instructions.
