Home Forums Eye Tracking Devices Pupil dilation with EyeX Reply To: Pupil dilation with EyeX


thanks for the feedback!

In general we have different eye tracking devices as well as sdk’s, depending on the requirements. So the Gaze SDK & EyeX SDK are interaction SDK’s, so to be used to interact with Windows devices. The EyeX SDK comes with an engine which e.g. detects click able objects in Windows and makes it very easy for developers to interact and integrate.

Pupil dilation has nothing to do with interaction, instead it’s related to analytical purposes, and from that standpoint it’s very difficult for us to prioritize and/or integrate that into our interaction SDK’s.
If you need pupil dilation, you will need to use our Analysis SDK which is not compatible with the Tobii EyeX controller.

As a side note I would also like to publish a link to the Gaze SDK & EyeX SDK license agreements, as it might be worth having a look at “Privacy and integrity”.
