Hi @kevinbrasswell, I am afraid the the Gaze SDK has been deprecated some time ago now and is no longer provided or supported by Tobii. Whilst we are intending on providing a replacement for the Gaze SDK in the future for the Tobii Tech range of eye trackers, it’s functionality will not necessarily be extended to assistive devices such as i-series.
That being said, your case may merit special consideration so I have emailed you personally the contact you should speak to at Tobii Dynavox about this issue.
