Recreating Eyes and Screens with Graphics in Virtual Space

[Colton Phillips]

Hello! I’m new to tobii but this is my question.

Is it possible to recreate in 3D using graphics, the xyz placement and direction (rotation) of your eyes and the tracked monitor (and maybe even the sensor)

I know how to use the API to get the x-y position of your gaze on screen and I know how to get an xyz placement of each eye. I’m not sure how the trasform position relates (i think it’s relative to the screen…)

I’m okay doing 3D math so I can probably work this out once someone gives me a solid idea of what information I can get from Tobii and how I can put it in the right format to be able to render 2 3D eyes and a plane representing a computer screen.

Cheers

Hi @coltonphillips, I am afraid we do not have a sample application ready for use with the Tobii EyeX/C4 which illustrates exactly what you are asking for. Indeed, however it is quite possible to implement.

The Tobii Pro SDK includes such an example though unfortunately is not compatible with the EyeX or C4.

Never the less, the code show at least show you the best way to setup the geometry to be shown on screen. You can download the ‘3D Eyes’ sample online @ http://www.tobiipro.com/product-listing/tobii-pro-analytics-sdk/#Download

Hopefully this should show you the best way to setup the application if nothing else.
