WHAT IS EYE TRACKING ?
In the simplest terms, eye tracking is the measurement of eye activity. Where do we look? What do we ignore? When do we blink? How does the pupil react to different stimuli? The concept is basic, but the process and interpretation can be quite complex. Below is a brief overview of eye tracking technology and its applications.

THE WORLD’S FIRST$99 EYE TRACKER WITH FULL SDK
Eye tracking has been actively discussed by technology enthusiasts throughout these years, but it’s really challenging to implement. But Eye Tribe actually did this. They successfully created the technology to allow you to control your tablet, play flight simulator, and even slice fruits in Fruit Ninja only with your eye movements.
It’s basically taking the common eye-tracking technology and combining it with a front-facing camera plus some serious computer-vision algorithm, and voila, fruit slicing done with the eyes! A live demo was done in LeWeb this year and we may actually be able to see it in in action in mobile devices in 2013.
Currently the company is still seeking partnership to bring this sci-fi tech into the consumer market but you and I know that this product is simply too awesome to fail.
THE PROCESS OF EYE TRACKING
Eye tracking data is collected using either a remote or head-mounted
‘eye tracker’ connected to a computer. While there are many different
types of non-intrusive eye trackers, they generally include two common
components: a light source and a camera. The light source (usually
infrared) is directed toward the eye. The camera tracks the reflection
of the light source along with visible ocular features such as the
pupil. This data is used to extrapolate the rotation of the eye and
ultimately the direction of gaze. Additional information such as blink
frequency and changes in pupil diameter are also detected by the eye
tracker. The aggregated data is written to a file that is compatible
with eye-tracking analysis software such as EyeWorks
