Eye tracker mouse movement is choppy on Windows with Tobii 4C #277

Closed grantnathanielbrown closed 2 years ago

When using a Tobii 4C eye tracker on a freshly installed version of Talon on Windows, the movements of the cursor derived from using only my eyes (as opposed to tilting or rotating my head) are somewhat choppy/laggy.

Please let me know if you need any more clarification. Thank you.

Can someone try running lib.timeBeginPeriod(1) in the Talon REPL on Windows with a 4C and see if it helps with the jitter?

grantnathanielbrown commented 3 years ago

Just tried that, didn't seem to have an effect. However, like we spoke about earlier, I've been having a similar issue when using my Mac (as well as someone else's Mac) so it is likely related to the Tobii hardware.

I've fixed all known issues relating to timer jitter on windows.

If there's still a lack of smoothness, I've been working on a new algorithm that is completely smooth and will hopefully launch in the next Talon release version.
