The project was born as a group exercise when I took part in an online course from Stanford University.
After the course finished, we realized our idea may have potential and decided to create a business out of it.
The idea was to use a small camera inside cars so in order to detect the eyes of the driver. This would allow to adjust the side view mirrors and eliminate blind spots.
As the main engineer I developed a working prototype. The first version implemented the algorithm on a web app by using the computer web cam. The second prototype used a standalone camera to control the mirror motors.
Thanks to the prototype we managed to get accepted into a startup accelerator, and we got angel investment for our company. We even spoke with several car manufacturers interested in our product.
However after a year of tweaking and retweaking the business model, it became apparent that it was time to move on to new projects. The main issue was the fact that our product was not patentable, and thus we had nothing of value to sell to car manufacturers.
