ANALYSIS DEVICE FOR DETERMINING THE LENGTH OF A DETECTION PERIOD CONTRIBUTING TO A LATENCY TIME IN AN IMMERSIVE VIRTUAL REALITY SYSTEM

摘要

The invention relates to a device (DA) performing analyses in an immersive virtual reality system, comprising a target (CD) secured to an object (O) that can move in a space (EP), and detection means (MD) for detecting the current position of said target (CD) in said space (EP) and delivering a first signal representing said current position. Said device (DA) comprises a sensor (CC) for generating a second signal when the object (O) reaches a known position in the space (EP), and analysis means (MA) that are coupled to the sensor (CC) and detection means (MD) and are used to determine a first time when a first signal representing said known detected position is received, and a second time when said second signal is received, and then to detemine a temporal distance between the determined first and second receiving times.
