ABSTRACT:
Directional microphone or microphones for position determination. One or multiple directional microphones are implemented in various locations to perform acoustic wave capture of acoustic waves associated with object (e.g., a player, a gaming object, a game controller, etc.). The generator of such acoustic waves may be co-located with the object (e.g., integrated into the object if the object is a device such as a gaming object, a game controller, etc., or integrated into clothing worn by a player such as on a hat, a jacket, etc.). The acoustic waves described herein may be generated by any number of means/devices including audio output devices, speakers, pulse wave generators, audio oscillators, etc. Moreover, such acoustic waves may be ultrasonic. A game module and/or processing module processes directional vectors associated with positions of the directional microphones when detecting relative maximum amplitude of an acoustic wave emits by an acoustic wave generator.
