Abstract
Methods and systems for dynamic tracking of on-stage objects using microelectromechanical systems (MEMS) presented herein do not require illumination to track a randomly moving object and are easily configurable for various stage sizes and for stages movable relative to the ground. In some instances, a tracking method includes determining an initial state of an MEMS motion tracker carried on a dynamic object, such as a performer. Acceleration and orientation information gathered by the motion tracker is monitored. A change of state in response to the monitored acceleration and orientation information is then determined. An instant state is calculated using the change of state and the initial state. Actuation signals based on the calculated instant state are generated for actuating a gimbal. The gimbal faces a device supported thereby toward the dynamic object.
