My day job is in the User Experience (UX) field. I lead a team that designs easy-to-use software interfaces. We employ usability engineering activities to prove our designs are easy to use.
Seeing as that's my expertise, I'd like to help:
Design an intuitive desktop environment for EyeTap from which all apps can be launched.
Create human interface guidelines that can be used by developers to ensure all EyeTap apps have a consistent user experience.
Advocate for usability testing as a means to validate the ease-of-use of any application developed for EyeTap. I can also help facilitate usability testing of apps for developers. More on usability testing here: https://en.m.wikipedia.org/wiki/Usability_testing
If there are any other UX designers interested in EyeTap, I'd love to collaborate.
