The last December 12 Sony Interactive Entertainment registered a patent in the Patent and Trademark Office of the united States reference to a HMD (Head-Mounted Device”, for its acronym in English) that reiterate in the filtration: the helmet of virtual reality will be wireless and will have multiple enhancements.
The patent, as detected by RespawnFirst, explains that the helmet does not require wires to connect with the PlayStation 5, or PC; mention is made that the design of the new HMD from Sony (the PlayStation VR 2) is capable of receiving video and audio signals wirelessly. It also suggests that there will be less involuntary reflexes in the eyes player.
A new technology to detect that the helmet is properly positioned

According to explain from RespawnFirst, the most devices, VR current detected by the user’s eyes with cameras, and using computer vision and machine learning. problem of using cameras is that, at times, the eyes of the player are not in the range of the objectives, something that is especially true with users who wear contact lenses or glasses.
The patent of Sony usa “ultrasound transducers” to detect the position of the eyes of the player. The transducers emit signals to the ultrasound from their antennas, or emitters. This is done by generating an electrical signal consisting of pulses of sine waves at an ultrasonic frequency. The transducers receive the electrical signal to convert to an ultrasound signal. The signal can be transmitted through the skin of the user.
