USER INTERATION SERVICE SYSTEM AND METHOD USING PROJECTOR

摘要

PURPOSE: A user interaction service system using a projector and a method thereof are provided to overcome the restriction of place and environment by using a portable user terminal and a lightweight projector. CONSTITUTION: A projector (100) magnifies image data which is to be presented on an external screen, and then projects the magnified image data. A user terminal (200) delivers image data of an application or contents to the projector, if the execution of the contents or the application for presentation is inputted. When an interaction signal of a user related with a screen projected through the projector is received, the user terminal performs the function corresponding to the interaction signal. The interaction signal of the user is a voice signal received through a micro phone, an image photographed through a camera, a shadow image made on the screen projected through the projector or a movement signal of the user terminal.
