On a personal level today marks an important milestone. I build my first gaze interaction software back in 2008, it was my masters thesis project at Lund University titled Neovisus. That's when I realized that this could be a natural element of future device control, not 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, it was difficult to setup, you had to order components to assembly your own rig and tracking performance was poor and far from automatic compared to commercial alternatives.
Overall, the ITU GazeTracker was a great experience, it evolved to become most distributed eye tracking software out there and gathered a strong online community. During these years we learned a lot. Enough to realize what needed improvement and what the missing parts were. It became apparent that we could not accomplish that in a part-time setting with sporadic efforts, to accomplish something great would take 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 financial barrier that's preventing developers for 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.
