On a personal level today marks an important milestone. I built my first gaze interaction software back in 2008, titled Neovisus, as the outcome of my MSc. at Lund University. During this work I realized that gaze interaction could be a natural interaction element, not just for a specific user group but for everyone. At the time eye trackers were unfortunately really hard to come by, the one I used costs $25,000 (and still does). Javier San Agustin and myself attempted to fix this during our R&D of the ITU GazeTracker, an open source eye tracker software. In many ways we succeeded, but it lacked critical features; you had to order components to assembly your own rig, it was difficult to setup and tracking was far from robust compared to commercial alternatives.
Overall, the ITU GazeTracker was a great learning experience, it evolved to become most distributed open source eye tracking software and gathered an active community. At the same time, we learned what it would take to build something great. It would require us to focus and make a full time commitment.
Here we are two years later. With the launch of an truly affordable eye tracker we have taken a big step towards realizing the vision we are burning for. No longer is there a prohibiting barrier preventing developers from exploring the many benefits eye tracking can bring to their applications.
Best of all, this is still the beginning. I can't wait to get this into the hands of all the developers who placed a $99 bet on the future.
