The clip-on Eye Tribe Tracker technology means you can hold your tablet in one hand and a pizza in the other while your eyes take care of the swiping and tapping on your devices. It connects via USB 3 and tracks the exact point that the user is looking at on the screen. It’s the smallest eye tracker in the world and allows hands-free navigation of apps and websites on tablets, laptops and desktops and device control such as aiming in games, eye activated login or hands-free typing. Currently available only for Windows PC, laptops or tablets, Android and iOS versions are also in the works.
An eye tracker uses invisible near-infrared light and high definition cameras to project light onto the eye and record the direction it’s reflected off the cornea. Advanced algorithms are then used to calculate the position of the eye and determine exactly where it is focused. This makes it possible to measure and study visual behavior and fine eye movements, as the position of the eye can be mapped multiple times a second. How quickly an eye tracker is able to capture these images is known as its frequency. A recording can also be made of the scene a person is looking at, and using eye tracking software it’s possible to produce a visual map of how the person viewed elements of the scene.
In this blog post we will explore the range of eye trackers available, what types of research each is most suited to, how to understand and interpret the results of your eye tracking study, and the unique benefits of using eye tracking in research.
