Hi @f3head, thank you for the interesting read. Yes, it is a great plug for the Tobii 4C!
Whilst we are of course excited about upcoming developments, as you may be aware, Tobii has been producing eye tracking devices for the accessibility market for many years with a range of devices so suit a varying array of needs.
If you are interested, have a look at Tobii Dynavox (https://www.tobiidynavox.com/) where you can explore the current products that we offer in this sector.
