eye control

The other night I was talking to a nice Swedish fellow named Hans who was looking for a place to go dancing after the bars closed. Although we could not think of a place open late for dancing similar to those he was used to in Europe, he did tell me about his company, Tobii. What he does is sell products based on what is known as "eye control." This innovation is CRAZY! It works by measuring a person’s point of gaze (i.e. where they are looking) and determining eye/head position. The origins of eye tracking are apparently over a century old, but in the last 5 years large technological advances have opened up new possibilities. Modern day eye tracking can be used not only in a laboratory, but in homes, schools, and businesses where it aids in research and analysis and is used for interacting with computers as well as with friends and family. Hans was in the states to promote this idea to businesses here...Imagine: no more clicking mouses or typing!? It is indeed a simple idea, but involves complex math. Eye tracking works by reflecting invisible infrared light onto an eye, recording the reflection pattern with a sensor system, and then calculating the exact point of gaze using a geometrical model. Once the point of gaze is determined, it can be visualized and shown on a computer monitor. The point of gaze can also be used to control and interface with different machines. This technique is referred to as eye control. This is definitely something worth checking out...
