Tyzx is creating a new way for the world to interact with people by providing "systems that see" - spatially aware environments and systems employing 3D vision. Spatially aware environments and systems automatically see, interpret and respond to people and surroundings by visually sensing action and motion. Examples of spatially aware environments and systems include person tracking for surveillance and assistance, gesture tracking for video game interaction, and collision avoidance and navigation for vehicles and mobile robots
