Abstract
Methods, apparatus and systems for movement tracking are described. In one example, a described system comprises: at least one sensor configured to generate at least one sensing information (SI); a memory; a processor communicatively coupled to the memory and the at least one sensor; and a set of instructions stored in the memory. The set of instructions, when executed by the processor, cause the processor to: obtain at least one time series of SI (TSSI) from the at least one sensor, analyze the at least one TSSI, track a movement of an object in a venue based on the at least one TSSI, compute an incremental distance associated with the movement of the object in a first incremental time period based on the at least one TSSI, compute a direction associated with the movement of the object in a second incremental time period based on the at least one TSSI, and compute a next location of the object at a next time based on at least one of: a current location of the object at a current time, a current orientation of the object at the current time, the incremental distance, the direction, or a map of the venue.
