Does this work with the tobii eye tracker 5?

as title says: Does this work with the tobii eye tracker 5 for use in games?

[xDShot]

Curious as well

[jblaszczyk]

sort of... I managed to calibrate Tobii Eye Tracker 5 with tobii_config
but can't run TobiiProEyeTrackerManager due to broken dependency:

(TobiiProEyeTrackerManager:5188): Pango-ERROR **: 22:41:47.895: Harfbuzz version too old (1.4.2)

this is a widely known problem with electron-based apps, not the driver itself

Did you manage to get the main running?

Did you manage to get the main running?

No not yet unfortunately

When I boot into Windows and use the eye tracker and then boot to linux the example works. When I reconnect the eye-tracker it does not work anymore.

Hello!

For me, the Eye Tracker 5 basically worked out of the box on Arch Linux after converting the tobii_config and tobiiusbservice packages in this repo with the tool "deptap".
Only the USB service kept crashing. It tried to create a PID file in /var/run/tobiiusb but the "tobiiusb" folder did not exist.
After creating the folder manually, and running the service as root I was able to run the tobii_config tool for calibration.
You can use strace -f tobiiusbserviced to see whether the child process exits with an error.

I also tested the stream engine SDK from this repository in my own project and subscribing to the gaze position worked fine. Subscribing to the head tracking however failed with a "not supported" error (it obviously works on Windows though).
Also, the tracking on windows seems to be a little bit smoother and better.
I guess, the stream engine and/or the tobiiusbservice are simply too old and do not fully support the Eye Tracker 5.
I did not try the example from this repo though.

Hope this helps someone :)

I got the TobiiProEyeTrackerManager running with the Tobii Eye Tracker 5 by installing an updated version, which can be found here https://s3-eu-west-1.amazonaws.com/tobiipro.eyetracker.manager/linux/TobiiProEyeTrackerManager-2.0.0.deb.

The manager can be used to calibrate the eye tracker. After the calibration the example ./main script runs fine.

Hi, I'm interested in developing a vim plugin that can use eye tracker. Do you know if the Tobii eye tracker API has the ability to give me the coordinate of a "box" from where I'm looking at?

[skewty]

@quantum-booty did you get anywhere with the VIM plugin?
I'd like to use it to control JetBrains IDE scrolling and active window/pane.

[dkbast]

@quantum-booty @skewty looks like this is the thread for likeminded people - I'm also looking into exactly this for vim and maybe VS Code. Did either of you make any progress in that regard?

[ifl0w]

@quantum-booty The API documentation is public and can be found here. So you can check whether everything you need is supported. You can get the point on the screen at which the user is looking and the position of the head or eyes relative to the monitor.

A Vim/Nvim extension would be super cool; I'd love to try that! And sorry for answering so late 🙈 !

Do you know if there is an RPM version of this or is there a listing anywhere of whats in this S3 bucket?

[betaboon]

fyi, the most recent version of TobiiProEyeTrackerManager can be found here:

• https://connect.tobii.com/s/etm-downloads?language=en_US
• https://s3-eu-west-1.amazonaws.com/tobiipro.eyetracker.manager/tobiipro.etm.linux.html

the second page redirects to the most recent release.
which is at 2.6.1 right now:
https://s3-eu-west-1.amazonaws.com/tobiipro.eyetracker.manager/linux/TobiiProEyeTrackerManager-2.6.1.deb

Hi does it work in games like StarCitizen?

[betaboon]

For all those interested, i figured some things out.

My work can be found here: https://github.com/betaboon/python-tobii-stream-engine.

In a nutshell:

• The publicly available Tobii Pro SDK contains libtobii_research.so.
• libtobii_research.so (even tho undocumented) contains all the exports that libtobii_stream_engine.so has.
• the contained stream_engine has version 4.24.0.33.
• header-files for the stream-engine exports are not available.
• documentation for stream-engine is available: https://tobiitech.github.io/stream-engine-docs/
• together with tobiiusbserviced this results in the device working.

I haven't gotten a recent version of TobiiProEyeTrackerManager to work and detect the device tho.
Which forces me to still use tobii_config for calibration.

maybe @derdrdirk has some insight on this?

PS: feel free to hop over to my repo for further discussion.
