PS5: Sony patents point out how the next VR headsets will create new ground

TThe most important improvements of the PlayStation 5 were already confirmed by Sony in an interview, in which with the first integrated solid state drive of a console a graphic blunder was promised. But while the game system is still about a year away, it looks as if the purported selling point of the PS5 is the device's virtual virtual reality headset.

Earlier patents, apparently for Sony's follow-up to the 2016 PSVR Headset, have shown that the device is completely wireless and can comfortably accommodate users wearing glasses. Most recently, a US Patent and Trademark Office patent application published on April 18 drew closer attention to Sony's plans to finally cap the VR enthusiast.

Sony has not confirmed it, but a tremendous amount of leaks allegedly posted by an anonymous game developer indicated that the PSVR 2 headset should be sold separately for $ 250 View, eye-tracking, five hours of battery life and integrated headphones. These state-of-the-art features are all possible without connecting to your console thanks to high-frequency radio waves.

The patent describes how the upcoming PlayStation console encodes VR video data at a frequency of 60 GHz, which is then transmitted to the headset and decoded. It also explains how this technique can be used for both games and video streams, allowing users to enjoy all kinds of intense VR experiences without tripping over cables or pulling their console out of position.

Here is an excerpt from the patent:

A head mounted display (HMD) comprising: a strap for attachment to a user's head; a wireless communication system having an antenna disposed at an upper side of the ribbon of the HMD, the antenna being configured to receive one [radio frequency] Signal from one [radio frequency] Transmitter, wherein the RF signal contains video data encoded in a compressed format; wherein the wireless communication system includes a receiver configured to decode [radio frequency] signal received via the antenna; an ad configured to render the video data. "

A built-in radio frequency receiver can record high-frequency waves sent to it from a Playstation console.

This latest patent deals with a barrier. For the coding system to function optimally, users must stay within sight of the console. Millimeter waves can wirelessly deliver huge amounts of data at blazing speeds, but the biggest drawback is that they have difficulty penetrating walls and bypassing surfaces.

The Institute for Electrical and Electronics Engineers (IEEE) has pre-tested this exact frequency and has been able to transmit data at a speed of 7 gigabits per second within ten meters. This also means that Sony has to make it clear that users need to stay close to the console, or that there is a risk of frame frames.

Going wireless would be a big deal. Sony's PSVR hardware has been nauseous in the past, and poor VR video rendering is a dizzying experience. The company needs to make sure that its wireless transfer function works properly so as not to disturb users when a PSVR wireless headset actually comes on the market.

The console's wireless transmitter can tune to beam waves to be exactly where the headset is in a room. This could help deliver video data to the headset quickly and avoid image drops or graphical glitches that can cause users nausea.

The patent addresses this potential problem by describing how the radio transmitter in the console is "configured to adjust a beamforming direction of the radio frequency signal toward the antenna of the wireless communication system." In other words, the console would track the headset and Accurately transfer video data to avoid interference when a player steps in front of an obstacle.

Typically, companies register patents for distant products that are still in conceptualization. However, a number of similar VR-oriented Sony patents and PS5 rumors indicate that a launch next year could be imminent. If the PSVR 2 hardware fails, this is a groundbreaking product for an industry-leading console.

No other console offers a wireless VR headset as an accessory. The Oculus Quest is the next best thing, but because it's a standalone headset, it does not have the graphics you get from folding the compute power of a companion console.

Sony has already announced that it will skip the June 11 E3 gaming industry show, which has traditionally released hardware releases. As the biggest competitors of Sony – Microsoft and Nintendo – will be present, we should expect in the summer with a stand-alone Sony event. With the steady drumming of patent news and confirmation messages about the PS5, it seems inconceivable that the company's VR plans are not mentioned.
