Abstract: A method for detecting a continuous circle gesture, has the following steps: receiving vectors representative of an object movement by a object detection unit; determining from the received sequence velocity vectors a sequence of velocity vectors or an approximation thereof; estimating an angle between subsequent velocity vectors; and determining a rotation direction.

Abstract: A position tracking system may include a processor and a memory coupled to the processor. The memory may include instructions that, when loaded and executed by the processor, cause the processor to receive a plurality of measurements from a sensor and map a location of an object to a measurement using movement models. The mapping may be based upon a cost computed from movement models, the measurement, and the location.
