Suggestions for Pimax

Now that “Sansar” is a released game on steam, I thought now would be an appropriate time to mention the fact that it still does not work properly with the Pimax. This is partially the sansar dev’s fault for being stubborn but I thought I may as well tell the Pimax devs so they are aware if a steam game doesn’t work well with their headset.

So firstly, with the pimax headset on and the game launched, it will seem to show nothing inside the VR headset, and when you pull up steamVR desktop mode, the headset will suddenly render one large frame in the background and the game will act like it’s in VR mode, but exiting the desktop viewer in SteamVR will cause the game to go back into desktop mode. Needless to say this is weird.

Secondly, while it is possible to get the game to flip modes forcibly (using f9 for those interested), the game will not track the positions of your hands and show them to other players, to all other players you will look like you are in desktop mode. This is due to the fact that the sansar devs rely on a proximity sensor input telling them that the headset is on. For wahtever reason, the Pimax headset does not read this to sansar correctly, and if sansar does not read a headset is on, it doesn’t want to show your movements to other people. (This was made to avoid seeing avatars bend over backwards when people take off their headsets, but again they are just stubborn lazy devs with it, as I’ve tried submitting a bug report to sansar for this.)

Hopefully this is a simple issue for pimax to fix like “oh we had this value backwards” or something like that. Thank you again for your continued development and improvements with this futuristic headset.

@Dallas.Hao @Matthew.Xu also please if you are reading this, I would just like to quickly point you towards my other post in here (hotlink: Suggestions for Pimax ) about the pattern of black subpixels being a major limiter of immersion right now. Thank you again for your time, and have a nice day.

Seems like Pimax “just” need to fake the proximity sensors data with that of their own gyro-based solution. Logically that is… :wink:

I have no idea if it’s that easy, but hopefully SteamVR just expects an “on/off” signal.

@Sean.Huang Please pay attention to this matter.

because Pimax has technical issues with SurveyMonkey, maybe you can Use GOOGLE forms…

Hi,

just to make a sugestion for the onlinee shop.
At the moment there is only ability to order complete hardware.

Please, allow in the shop to order consumable/hygenic parts.
Like:

  • face cussion
  • headstrap
  • prescription VR-frame

I hope this is the right place for it
regards

@Matthew.Xu @Dallas.Hao @xunshu @Sean.Huang @Doman.Chen @Alan.sun

For Pimax’s assistance, here are a list of problems and their proposed solutions compiled from reading different threads across the forums for assistance in improving the quality of the overall experience and quality of future backer and future consumer models.

_________________________________________________

Problem:
Dull colours on the Pimax 5k+ and 8k.

Solution:
Colour, contrast, saturation, brightness control, adjustable by pressing a combination of buttons on the headset, and in pitool.

_________________________________________________

Problem:
Janky configuration each time opening a game adjusting settings. (No Plug’N"Play functionality.)

Solution:
Saving pitool game config settings (FOV, Parallel projection, Brainwarp etc), as in a profile manager for settings for each game in pitool.

_________________________________________________

Problem:
Not clear enough image on the 8k.

Solution:
Sharpening filter akin to the setting in vorpx to improve sharpness on the 8k, or change input signal to 1080p on the 8k to upscale to 4k in the right ratio, as 1440p does not upscale to 4k in a 1:1 ratio.
_________________________________________________

Problem:
Edge peripheral distiortion too high/Large FOV unuseable.

Solution #1:
Better distortion correction profile to make large fov mode useable,and make objects stretch less in peripheral edges of the screens on each eye.

Solution #2:
Sweet spot in the headset rendered to move along with the focal point of the eye (*Maybe achievable using nvidia multi-view rendering or other turing software architechture seen in their whitepapers https://devblogs.nvidia.com/turing-variable-rate-shading-vrworks/ ](https://devblogs.nvidia.com/turing-variable-rate-shading-vrworks/ ))

_________________________________________________

Problem:
Distortion in general/bad HMD seating/hard to find sweet spot.

Solution #1:
Increasing face cushion length to 15mm-20mm decreases distortion - At least two types of face cushion foam (a smaller and a larger, 13mm and 15mm) and deluxe audio strap included with future consumer models.

Solution #2
A face cushion with a tilt to reduce distortion as one user modded in this thread https://forum.pimaxvr.com/t/i-get-rid-of-all-issues-with-only-one-simple-mod/12978 , or a tilt in the DAS at the top vertical placement of the HMD.

_________________________________________________

Problem:
SDE on the 5k+ and 8k

Solution:
An optional Anti-SDE screen layer protector, such as the Tech21 iphone screen protector for future 5k+ and 8k consumer models to further reduce SDE, similar to what is offered by Samsung Oddesey+, offering backers the opportunity to send in backer HMDs to be modified and fitted with Anti-SDE technology the same as future consumer models may have.

_________________________________________________

Problem:
Black dots on the 5k+ making SDE appear worse than normal.

Solution:
Possible firmware update solution, or requesting the 5k+ screen manufacturer to fabricate screens custom made to remove the digitizer layer if it be the source of the black dots.

_________________________________________________

Problem:
Bad performance on mid grade GPUs below the GTX 1080ti.

Solution:
45HZ/60HZ Brainwarp to 90hz/120hz.

_________________________________________________

Problem:
Unergonomic controller design.

Solution:
Offer a controller design without the tracking ring which wraps around the wrists, to avoid them colliding with each other when hands are close together, an improved prototype design with a tracking ring similar to valve knuckles tracking ring.

_________________________________________________

Problem:
HMD plastic housing cracking after delivery, or at delivery, causing light bleed.

Solution:
Sticky tape temporary solution otherwise RMA for replacement.
Assume its caused either by internal force, pressure from its shape or inadequate quality plastic.
(i) Better delivery packaging; and,
(ii) Either alter assembly or HMD plastic housing moulds slightly to allow more space between fittings to reduce the amount of pressure/tension,
(ii) improve the quality of the plastic housing,
(iii) use a silicone/rubber gasket in between the joints to prevent stress forming cracks in future models,
And offering backers the opportunity to send HMDs back to receive upgraded plastic/rubber gaskets if they receive a fault or if they want it, if Pimax decides to use them instead of upgrading plastic.

_________________________________________________

Problem:
Latency issue with tracking HMD on the 8k / 8k “wobble”.

Solution:
If anyone has a suggestion, suggest it in this thread, the issue is provided in this post for Pimax’s reference.

_________________________________________________

Problem:
“The world” moving with you when moving head in both 5k+ and 8k.

Solution:
Incorrect firmware: Contact Pimax support for firmware update.https://forum.pimaxvr.com/t/anyone-having-moving-world-or-finnicky-tracking-issues-using-basestations-please-read-here-for-info/12557/11

_________________________________________________

Problem:
(User related) HMD not being picked up by Pitool

Solution:
Try a different USB port which can provide adequate power, or delete all associated Pitool folders in C: and /appdata/ and reinstall the latest stable version of Pitool.

_________________________________________________

Problem:
Stuck pixel/white pixel/dead pixels

Solution:
Better packaging (thick bubble wrap in between the boxes), better QA before shipment,
RMA for replacement if this fix doesnt work
http://www.jscreenfix.com/fix.html

_________________________________________________

Problem:
Screen flickering / light bleed from backlight/ dots appearing on screen/ differing screen brightnesses/ lcd tear

Solution:
Better packaging (thick bubble wrap in between both boxes), better QA before shipment.
RMA for replacement,

_________________________________________________

This poll seems to indicate the dead/stuck pixel issue only affects the 5k+ and is not an issue which affects the majority of owners.
https://forum.pimaxvr.com/t/detailed-poll-for-owners-dead-pixels-8k-5k-black-dots-5k/11960

I made a more detailed poll for the community with respect to the experience backers have had with quality, more input from backers would be useful.

Poll: Multiple choice polls to survey backers experience of quality Pimax 8K

This post is to provide backers and pimax with useful statistical information in relation to backers experiences with the quality of experience backers have had with several issues. Did your first headset have any dead pixels? Yes, one dead pixel. Yes, 2-3 dead pixels. More than 4 dead pixels. No dead pixels. 0 voters Did your RMA replacement headset have any dead pixels? Yes, one dead pixel. Yes, 2-3 dead pixels. More than 4 dead pixels. No dead pixels on my replacement head…

_________________________________________________

Pimax confimed in another thread where a backer compared two HMDS they received, that parts for plastic housing used in construction may be different, but that hardware is the same, in response to the backer raising the fact the HMD straps on two models he received were different.

@Matthew.Xu, as plastic housing may be different and an anti-sde layer isnt hardware, I suggested that the plastic housing be improved / moulds be changed to allow for more space / rubber gasket be added in between the plastic housing to reduce crack causing tension, and an anti-sde solution be added to design of future backer and consumer release models.
to remove SDE entirely as advertised in the KS campaign, whilst giving backers who want it the opportunity to send the HMD back in to upgrade plastic housing and add anti-sde solution if they want it.

Alternatively, if Pimax decides to sell a HMD with an anti-sde solution to consumers as a different model, backers should still be given the opportunity to receive an upgrade by sending their HMD in for upgrade if they want it.

New proposed naming conventions for new models with anti-sde layer technology:
8K Pro - 5K+ Pro - 8KX Pro (Models with anti-sde layer)
5K BE Pro - 8K BE Pro (Business models with anti-sde layer)
or
8K - 5K+ - 8K+ (TBR) (Standard models - Renaming unreleased 8KX to 8K+)
5K BE - 8K BE - (Business models)

8K X - 5K+ X - 8K+ X (Models with anti-sde layer, X is added)
5K BE X - 8K BE X (Business models with anti-sde layer)

If there’s anything else I’ve missed, post it in the comments and I’ll add it to the list, I didn’t include any ghosting issues as they are reported to be solved on the 8k and the 5k BE and they don’t occur on the 5k+.
