Mr.uu's 8KX Eye Tracking Installation Experience

Just installed the eye-tracking module in about 20min.


Removing face mask was easy, starting from the lower nose part.

Removed the part needed. Plastic is soft, easy to cut just pressing downwards.

Cleaned the lenses, removed the adhesives from the frames, applied the frames, removed the protective foil from the backside of the eye-tracking glass, pressed first the plug on top in the hole of the hmd (where the USB port is on non 8kX models) then positioned the modules on the metal rings, removed the adhesives on the front glass side.

Dialed the ipd to lowest (helps with guiding the cabling for the two eye-trackers (removed the face foam for it)
Finished!

Downloaded the PiSDK from the 7invensun Website.

Now I am curious to try it out…

Edit: forgot to show you how I routed the cable from the lower usb-port:


The lower plug plugs in firmly, the upper one sits less firm. Should work. Now let’s try it out!

Those adhesives, are they necessary?

no magnet attachment?

Okay…hmmm… @PimaxVR you make me crazy!

From the beginning:
Turned on the hmd and dialed the ipd in. From around 67mm on I realized a tension on the eye-tracking cabling to a point where the eye-tracking modules suddenly snapped out of position.
So I checked the cut-out:


And extended it in a way that the cables have more room outwards:

Then I put the face mask in place and:
Realized that there is still tension, especially if the foam is on and the forehead presses onto this area. Then the Lower part of the modules snap Up. Sh*t.
So I made even more room, to a point where there is no pressure anymore on the cables:
Even so it looks terrible, the outer side cut is not visible because hidden by the tracker electronics part.

Did try the sdk calibration but that didn’t work. The green dots representing the eyes immediately disappear. Something not working here. I even closed pitools, but that didn’t fix it either.

There is. But it is so weak that It does not really help in fixing the modules in position

Sweviver or Someone said no, but I tried and was in no way happy with the metal rings rigid ness. There is just a 2cm notch on top and bottom which supposedly fixes itself with the cloth above and below the lenses. Was a Little loose still. So I used the adhesives

That sucks. I want to try them on my 5K+ but also on my X which will arrive later

Is that your 8K X ?
Those do not look like metal buttons ??
Edit: aaah you probably lend that pic from somewhere else.

I’ll use some double sided tape on my 5k+ so when/if I get an 8KX I can swap it over

I have to agree they look like black plastic buttons in the last photo.

tried an hour with different downloads from the 7invensun site.
Nothing worked.

unplugged and replugged the top usb cable which was a lottle woblling. detected again the eye tracking but same result.
opened the device manager and have a new device under cameras. Properties of it showed a not migration because of another similar device?

tried to start first pitools, then steamvr then the eyetracking runtime. started the calibration and… black hmd. did need to un and replug the hmd. then i tried again several times. but that did not happen again.

i think i wait for the new pitool.

I have a second eye-tracking module. Do you want me to try it on an 8k or a 5k+? Later i wil swap it on my second 8kX when it arrives.

We have to take your word on it then. :wink:

5k+ please probably the most popular hmd

If it could function I would like to see its use on the 5K+. But considering it is basically just an interesting looking addition to an already interesting looking headset…it just basically looks cool. Hope we all can get something useful out of it soon. Thanks for your effort and impressions here on the forum.

Why did you order a second 8KX and eye tracking module?
