Frequent disconnects begin after ~30-45m

Summary

On initial connect, link is stable however some time later head tracking will freeze in game and resume after 5-10s. Intervals between freezes are not predictable.

Scenario

  1. Open eyewarebeam app on iphone
  2. connect USB and enable streaming in eyewarebeam app
  3. verify eyewarebeam app on PC connects
  4. [optional] perform calibration
  5. start Opentrack and verify connection from eyewarebeam
  6. play game (in my case, IL-2 Sturmovik).

Expected result

Head tracking working as expected

Actual result

Headtracking freezes occasionally. This usually does not start immediately, but once it does it will re-occur frequently.

Content/Useful Information

Connection is via USB cable. Have not attempted any other connection options.
Disconnection can be observed occuring while out of game on Windows desktop, with eyewarebeam adn opentrack apps open. eyewarebeam icon in system tray shows disconnected, then reconnected, and opentrack “octopus” movement matches connect/disconnect in eyewarebeam app.

After disconnecting phone it is warm to the touch, but not overly so.

Hi Foxbait,

Please excuse our delayed answer.

After you start experiencing the issue have you tried recalibrating?
Recalibration is recommended if you have moved, if you have tilted the screen, if you have changed the position of your iOS device, if the level of light in the room has changed. To use Beam you must have good illumination.

The position of your iOS device is important when using Beam if you’re using an external monitor the best position is under the screen in the center, if you are using a laptop the best position is on either side of the screen in landscape mode for both cases make sure your iOS device is as close as possible to the screen and is positioned so that the camera sees you clearly.

Are you using an external monitor? I yes, what size is the screen?

If after recalibration the issues cease, then most likely one of the above reasons was responsible for the issue. If the issue is still occurring please make a video recording so we can better understand what is happening in your environment.

Thank you,
Sabrina

Hi, thanks for the response. I did not attempt recalibration as this had been done at the start of the gaming ‘session’ and when connected it appeared to be tracking correctly. In some subsequent testing I did notice that disconnect / reconnect via the app on the phone appeared to restore some stability (i.e. stopped the ongoing disconnect/reconnect activity) however I did not test how long this would last in use.

Unfortunately I no longer have the app installed - I was not using it while waiting on a response and found that it interfered with PC sleep ability (not going into sleep/waking from sleep), so I uninstalled it. I have also since purchased a hardware-based head tracking setup so will not be reinstalling Eyeware Beam.
