Possible PSVR 2 patents aim to reduce motion sickness and add an updated tracker calibration device

With the PS5 set to launch this holiday there are some questions regarding the future of VR, more specifically how Sony will be handling the jump to the next generation with PSVR. There have been a number of rumours and patents about PSVR 2 but Sony is yet to be drawn out on announcing anything in an official capacity. However, two more patents have recently been uncovered by TheGamePost that point to Sony working on a motion sickness reduction system and updated tracker calibration systems. Motion sickness has proved to be a sticking point for players and developers alike though many VR games to feature comfort settings to reduce the impact of it. However, with Sony aiming to reduce the effects of motion sickness, which in turn could attract more players, that may mean developers will not have to consider as many comfort options for their games.

The motion sickness patent reads as follows:


Provided are a VR sickness reduction system, a head-mounted display, a VR sickness reduction method, and a program with which it is possible to further reduce VR sickness. An HMD (12) is provided with a display unit (38), which is disposed in front of the eyes of a user when the user wears the HMD (12). A shaking unit (42) can shake the head of the user wearing the HMD (12). An entertainment device (14) causes the display unit (38) to display a moving image representing a view as seen from a viewpoint. The entertainment device (14) controls the shaking of the shaking unit (42) in accordance with the acceleration condition of the viewpoint for the moving image displayed by the display unit (38).

Here is the abstract for the tracker calibration device:

Provided are a tracker calibration device, tracker calibration method, and program that make it possible to precisely calibrate a plurality of types of trackers without measuring the relative positions of the trackers beforehand. A tracker data acquisition unit (50) acquires a plurality of items of first tracker data indicating the position of a first tracker expressed using a first coordinate system. The tracker data acquisition unit (50) acquires a plurality of items of second tracker data indicating the position and orientation of a second tracker expressed using a second coordinate system. On the basis of the plurality of items of first tracker data and the plurality of items of second tracker data, a parameter estimation unit (58) estimates parameter values for converting the positions expressed using the second coordinate system into expressions in the first coordinate system and estimates the relative position of the second tracker in relation to the position of the first tracker.

A few months ago Sony also patented a finger tracking PSVR controller which could allow players to have a much more immersive experience when playing VR games. If Sony is planning to release an updated version of the PSVR we may hear more during a PS5 showcase event in the next couple of months.

From the heady days of the Mega Drive up until the modern day gaming has been my main hobby. I'll give almost any game a go.


  1. Good news. The one thing that has stopped me hopping on VR is motion sickness. Didn’t want to waste £200 on making myself hurl. I’m ok with motion and travel, but as soon as I read a book/map/phone screen in the car (not driving) it becomes windows open time.

    Really should see if I can borrow one at some point to try it out. So very much want to soak up Star Trek in VR

    • I’m the same. Fine with everything except reading in a car. But after a short time in VR, I’m fine there with all the comfort options turned off.

      You need to find someone who will let you borrow one, or let you have a go several times. Try it, if you feel sick, stop. Then try again later. Or another day. Don’t give up after 10 minutes. You might need several sessions to adjust to it. A lot of people do, and most get used to it fairly quickly.

      And something like Star Trek is a good place to start. No movement, just sit there doing things. (Do not stand up and switch to the external view while going into warp! That’s enough to make even VR veterans feel unwell!)

      • I may well just dive in next month. Sounds like something you can adjust to.
        The 3DS screen never gave me the headaches some complained about, so maybe VR will be fine.

  2. Any attempt to reduce motion sickness is a good thing, and also a potentially bad thing.

    It affects people in all sorts of different ways. Most people might suffer a bit to start with, but get used to it fairly quickly. Some people (allegedly games journalists) seem to have a massive problem with VR to start with, get asked to review a VR game, jump into VR for the first time, feel a bit unwell and claim the game and VR in general are terrible. Wouldn’t surprise me if that even causes motion sickness in normal people. Get told VR will make you feel sick enough and a sort of placebo effect kicks in.

    The problem if Sony come up with some cunning way to reduce motion sickness is if they insist every game uses it. Which seems likely, given some of the things they insist on for VR games. What if it works for most people, but makes things worse for others? What if developers avoid all the other options because of it?

    Need some of the more extreme comfort options but find they’re not there because they’ve only got Sony’s option there? Tough luck.

    Find Sony’s option makes things worse? Better hope you can turn it off.

    Currently most (not all) games have all sorts of comfort options you can turn off (and Sony usually insist on them being on by default). Blinders (that weird tunnel vision when you move thing) just disturb me. Teleporting is fine in some situations, confusing in others. And snap turning rather than smooth turning does the opposite of what it’s supposed to. For me. Other people need some of those options.

    Any solution Sony come up with will make things worse for some, better for some, and not really do much for everyone else. And developers really do need to still add all those comfort options they currently add.

    Personally, if Sony’s option can be turned off and it means I don’t have to turn off all the other things in every single game, I’m happy. Or if I can turn off Sony’s option and all the others, I’m happy 30 seconds later. But some people could end up being worse off.

  3. I found prolonged use helped. 2 most effect I’ve for me was sitting down keeping me head straight. This was good for 1st person. Used it like a 2d game you get immersion, not to full but it’s still 3d. However , the most effective was having a few pints. I was able to play farpoint for 3hours solid without any sickness
