According to embodiments of the present invention are a system and method that use projected structured patterns of light and linear optical sensors for motion tracking. Sensors are capable of recovering two-dimensional location within the projection area, while several sensors can be combined for up to six degrees of freedom tracking. The structure patterns are based on m-sequences, in which any consecutive subsequence of m bits is unique. Both digital and static light sources can be used. The system and method of the present invention enables high-speed, high precision, and low-cost motion tracking for a wide range of applications.

System and method for tracking objects with projected m-sequences

Techniques for presenting display frames projected using a handheld projector. Embodiments detect a marker embedded in a display surface. A first display frame is projected onto the display surface from the handheld projector, where the first display frame projects, on the display surface, one or more animated objects positioned relative to the detected marker embedded in the display surface. Embodiments generate one or more subsequent display frames projected from the handheld projector, where at least a first one of the animated objects in the one or more subsequent display frames is positioned relative to the detected marker embedded in the display surface.
