Hi there! For starters I wanted to say I love SUVA and I'm glad to see further development of it. ❤

I just wanted to ask about the Tobii eye tracking as there are some changes that seem to be a step forward but with some caveats. It looks like the intention in the new version is to have the virtual monitor track with head movement somewhat but now I'm having my eyes get stuck as I tend to look off the main screen over at a second monitor frequently to read messages. When I look back at the main tracked monitor, my eyes are locked to one side. I seem to have to over extend my head in the opposite direction to re-centre my eyes again.

I was wondering if there would be a way to set a threshold perhaps to reset the virtual display position relative to the current head orientation or maybe put something like a dynamic bone on the virtual screen object to have it smoothly transition back to the current head location?

Of course I'm not a dev or anything so please correct me if I'm missing something or interpreting this incorrectly. 

I took a quick video to illustrate the problem I'm having all be it with exaggerated head movements. 

Any assistance is much appreciated!

Thanks for letting me know. The eyes will close when looking at a second monitor.  That is a limitation by Tobii tracking and the way I interpret blinking from it. 

What should not happen however is that the eyes get stuck.  I will look into that.

Besides that I noticed that your avatars eyes are very twitchy. You may want to increase the virtual monitor distance and adjust the limits a bit.

Thanks for looking into that. I'm aware the tobii tracker only can do one monitor unfortunately but yeah the eyes getting stuck is a bit annoying.

As for the twitchy eyes, I tend to distance the monitor like you suggested but left it on default settings just to illustrate the issue. 

Thanks again!

So I just wanted to revisit this since I had to upgrade to the 2019 unity version which still has this issue.

I noticed that it looks like the virtual screen position is relative to the chest/spine direction which can sometimes lag behind the position of the head due to the way the IK is implemented. 

Is it perhaps possible to position the virtual screen relative to the head direction instead?

Eyetracking is implement to always look at the camera, it is not relative to the head or chest. You can test this by looking at the center of the SUVA window and rotating the camera left and right, you will see that the avatar keeps looking at you until it hits its range limit. In SUVA 2.0 this entire system gets updated and you will be able to choose what is being looked at. SUVA 1.X will not receive any feature updates but only bug fixes when needed. This is not a bug though, this was by design.
