Light direction detector systems and methods

Intensity of a light from a light array comprising a plurality of light sources configured to illuminate in sequence may be detected at two optically isolated points of a motion tracker device. The optically isolated points may be disposed at a distance from one another such that a variation in inte...

More Information
Summary:Intensity of a light from a light array comprising a plurality of light sources configured to illuminate in sequence may be detected at two optically isolated points of a motion tracker device. The optically isolated points may be disposed at a distance from one another such that a variation in intensity of light due to shadowing effects from the plurality of light sources is different at the optically isolated points. The optically isolated points may be separated by a T-shaped wall. The motion tracker device may generate a current signal representing a photodiode differential between the two optically isolated points and proportional to the intensity of the light. The current signal may be used for sensor fusion with an inertial measurement unit.
