I believe we realize that it’s currently a beta tool, but it’s also the best option available (such as having the most forgiveness for head repositioning among current options) and very functional and coupled with outside developer programs. Aside from being really cool, Tobii seems certain to be a large player or one of the leaders in eye tracking, and so unless there are other options or Tobii products of which I am unaware, it’s probably a good choice. It’s also worth some risk to reduce mouse strain after having dealt with RSI. I was just thrilled to find a functional, publicly-available beta device.
Also, based on your work at other companies like Samsung and The Eye Tribe, I honestly wouldn’t be surprised if eye tracking became standard in computers within five years–and actually surprised if it hasn’t in 10. Does Tobii have similar any predictions or hopes?
