Recommended Way of Determining Eye Tracker Capabilities

[R]

Is there a recommended way through the C++ SDK to determine the difference between eyetracking models such as the EyeX2 and EyeXLite? The EyeXLite does not appear to support eye tracking but does support user presence. I would like to make different application decisions based on the capabilities of the eye tracker which is present.

Hi @randr, so within the EyeX SDK there is not the means to directly query the eye tracker model unfortunately, however as you pointed out across models some features are present whilst other are not (such as head tracking, presence, etc). Your best bet may be to cycle through these at startup and based upon error feedback, direct the program accordingly. Not a very elegant solution, but something to try out.. I will attempt to find a better one for you in the meantime.

Thanks Grant. I can get the model name and generation. Is there a list of available EyeX models and features somewhere on the Tobii site? I looked but was unable to find one.

Hi @randr, we only now advertise the two models of Tobii Gaming eye trackers, the EyeX and the C4. We not present a feature comparison chart, but you can get the specifications of each tracker via their own unique product page

We did produce another tracker (the REX) some time ago, but that is not deprecated and no longer advertised.
