Tobii eyetracker 4c feeback

Can you share some feedback from the device - have you tried to use it as mouse replacement?
I was planning to use it as mouse replacement, but heard not so good feedback (especially the accuracy required to position on a specific point).

Hi, the device is very bad. It has poor support for Linux and the latency and accuracy is too high to replace the mouse

Have you tried with Windows 10? On the videos the latency looks pretty ok

Accuracy is what is probably problematic. My Plan is to run it in a Win VM in Ubuntu.

Seemed to be fairly okay when I set it up with Ubuntu. Similar accuracy and setup as Windows.

@Eitol what would you recommend for linux support? I like this one for being fairly cheap.

I work in a project called Caster which allows people to control the computer and even develop applications by voice.

A member of the community tweaked EyeXMouse to make the eyetracker 4c a more reliable mouse replacement. Perhaps it can be reimplemented in this project. Versatilus's EyeXMouse fork features include on Windows.

• Simple filtering and averaging to keep pointer movements smooth.
• Nonlinear acceleration, allowing slow movements near the eyes' focus for more precise control but allowing quick movement when focus changes rapidly.
• Only updates the pointer when both eyes can be tracked. This allows reading pop-ups with minimal effort by closing one eye.

I have my eye on this project as I'm working on cross-platform in Caster. Does tobii eye tracker linux go against Tobii terms of service?

@LexiconCode that's super interesting and I definitely want to try it out. Does this require a tobii pro sdk and the license key, because without a properly activated tobii pro setup I wasn't able to get this to work since this project seems a lot more researchy.
