Can we please get a status update on what Pimax’s plan is to address the eye-strain and IPD discrepancy issues many people are reporting, such as these backers? https://community.openmr.ai/t/the-pimax-5k-is-garbage/16916/23
I know Pimax has stated theyre looking at releasing a new facial foam to address distortions, I would suggest that a PSVR styled headstrap is looked at to connect to the HMD at the top, allowing for the headset to be angled upwards or downwards and in/out closer and away from the face to address distortions.
This issue of distortion is separate to IPD measurement discrepancies from other consumer vr headsets like vive or oculus, which create confusion as to the correct measurement for set up, and the eye strain is another seperate and more important issue to address, which can make the 5k+ and 8k impossible to use for some people. For compatibility improvements, maybe parralell projections and brainwarp should be left on by default to minimise compatibility issues for most use case scenarios, or an auto detect feature for parralel projection to set it on if its required due to the rendering of content.
Also any news about the pitool settings profile saver and pitool colour/contrast/gamma/saturation/sharpness settings for pitool? Maybe some news about this could address peoples concerns that the 5k+ is too dull compared to OLED vr displays, and to make setup for games a lot easier and faster.
The IPD issues identified are as follows:
-
Minimum physical IPD amount on each headset is not minimum 55mm, it varies from 55mm-60mm headset to headset.
(whether this issue is a result of minor physical discrepancies between each headset affecting minimim IPD measurement slightly and caused by manufacturing differences in lenses and production, or if it’s caused by software issues reporting incorrect IPD measurements is yet to be seen.) -
IPD software measurement shown on display when the IPD wheel is adjusted on the headset is around 3mm-10mm off to the actual physical IPD measurement
-
Some headsets have discrepencies/inconsistent and incorrect values between the measurements on the IPD adjustment wheel on the headset and the measurement shown on the display when the IPD wheel is adjusted.
As for eye strain, maybe fixing the above mentioned IPD issues by offering a paid lens replacement if its required will fix the eye strain problems for many if its not resolveable by software changes of the IPD reading.
Here are some of the potential causes as to why correct IPD measurements do not work on Pimax headsets, when they work on the Vive and Oculus
Correct minimal physical lens distance measurement (physically 55mm apart), but incorrect software reading.
Assuming the software IPD readings pitool gives are often incorrect and the actual physical minimum IPD on the headset hardware is in fact 55mm, someone whos minimum IPD measurement is 60mm on pitool might need to add an additional 5mm more than the (perceived correct and optometrist measured) IPD measurement given on screen, whereas if it says 58mm minimum then an additional 3mm to real IPD measurement might need to be added.
That’s complete conjecture though to try and explain this and needs to be tested.
Incorrect physical lens measurement (not 55mm, but rather closer to 60-65mm), and incorrect software reading (reporting less than it is).
It could also be the other way around, that the minimum physical IPD setting possible by adjusting headset hardware is not 55mm, and it is in fact 60-65mm physical minimum IPD between both lenses, and the software reports a lesser reading to what the physical lens IPD measurement is, and that may account for the discrepancy between software IPD readings in pitool and physical IPD measurements not aligning, because software reports that the IPD is less than it actually is, and the reason why 3-10mm must be added in Pitool for an accurate IPD.
Solution for IPD discrepancy/Eye strain:
Offer backers solution for 150 FOV lens replacements to fix IPD issues, available for purchase by sending in to Pimax office for $100 upgrade lens/lens adapter at the cost of the backer, or using the $100 voucher if the backer has one. Also allow setting of IPD of each eye in software, for those with asymmetrical faces, and an IPD setting graphic on startup displayed on screen as shown in this thread, to assist in setting the correct IPD, as oculus rift has.
Solution for SDE complaints:
Consider offering a solution to completely eliminate SDE at the same time by selling an Anti-SDE solution as a send in upgrade, and on 8k and 5k+ Pro models as well, as well as the smaller fov lenses with lens adapters.
Solution for dull colour:
Implement a colour settings in pitool for contrast, saturation, sharpness, and gamma into pitool.
Solution for easier plug and play functionality:
Pitool settings profile saver for each game, and brainwarp and parralel projections automatically enabled until a code is written to assess and enable parralel projections in each game when it’s required for rendering correctly.
