ScreenFX creates interactive screens that display dynamic interactive multi-media content on any LCD screen, plasma screen or glass storefront window. Using GestureTek’s multi-patented, camera-based body tracking and gesture recognition technology, the system actually looks out at the surrounding area and reacts directly to the movement of people nearby. Customers can't ignore interactive signage on display screens or retail windows with point or touch interface that tracks their movement and responds creatively with dazzling interactive images and special effects. Passers-by instantly notice that simple body movements such as the sweep of an arm create magical changes to the screen’s graphical content. Dynamic multimedia imagery can be integrated with any branded messaging or corporate logo, creating a powerful advertising medium.
