Mirror displays and show gaze traze on only one of them

[Rickard Fjeldseth]

Hi!

Think of the following setup: a laptop connected to both a TV and a 24″ monitor.
Me, as sitting in front of the 24″ monitor, wont see any Gaze Traze. But the other people in the room that’s looking at the TV will see where the gaze traze.

Is there any possibility for this today?

Best regards

Hi @fieldset and thanks for your query. I am afraid that the Tobii Gaze Trace functionality does not offer the feature to specify a particular monitor to stream to, but perhaps you have already looked at Tobii Ghost? This would allow you to stream the gaze overlay to a different computer in turn connected to the TV which may be a workaround?

You can also look at using the Tobii Streaming Gaze Overlay which offer similar functionality and you can read more about @ https://blog.tobii.com/introducing-streaming-gaze-overlay-d4b02c87430b

In terms of using only one system, You could conceivably set up a virtual machine and run this as a virtual second PC to connect to the host via Ghost or TSGO although I am not sure such a procedure has been tested before!

Please let us know if you think any of these solutions are viable and if we could be of any further assistance.

Update: Tobii Ghost is a new name for Tobii Streaming Gaze Overlay and you don’t need any virtual machines for such setup.

This was exactly what I was looking for, thank you for your answer @Grant!

Just noticed that Tobii ghost seems to require Windows. Is there any linux support? 🙂

[Grant [Tobii]]

Hi @fieldset, I am afraid Linux is only available via the Tobii Pro SDK which in turn requires the purchase of a special analytical licence to operate.

Further information @ https://analyticaluse.tobii.com/ Apologies for any inconvenience. Hope you get up and running in any case!

Okey, that’s too sad. Altought I absolutely understand that you care about user privacy, which is great. I think I can work around it somehow. Maybe by running windows as host and linux in a VM.

Thanks 🙂

Hi @fieldset, yeah sorry about that, hopefully the workaround is satisfactory. Please let us know how you get on with the virtual solution .. would be great to hear how it worked out for you!

Hi @fieldset
You can run Tobii Ghost and OBS.
Disable preview in Tobii Ghost.
Add Desktop Capture layer in OBS.
Add Tobii Ghost as Game Capture layer in OBS.
Select Project to Second screen in OBS.
Done.
