PURPOSE: An apparatus and a method for displaying product information using an interactive window are provided to enable efficient advertisement about products. CONSTITUTION: If a window(101) is touched, a measuring unit receives time information from detecting sensors(110a-110d). The measuring unit measures the coordinates of the touched spot. A controller(140) accesses the detailed information about the product corresponding to the touched spot from a database(130). The controller transfers the coordinate information and the detailed information to a beam projection device(160). The beam projection device displays the detailed information in the fixed display zone based on the coordinate information. |
