Eye Tracking

Eye-Tracking © Ch. Gorke

Eye Tracking

Eye tracking means capturing the eye movements of a person. With this it is possible to determine how users perceive an operating surface, for example, to detect possible improvement measures.

The eye tracker of the Media Production Group is a mobile device, a so-called head-mounted eye tracker. It consists of a frame similar to one for eye glasses which is put on by test subjects and can be fixed directly on the head. The two cameras mounted on this frame record the vision field of the test subject as well as the subject's eyes.
The mobility of this device enables testing not only in the Usability Laboratory, but also on the field. The vision field of the test subject is hardly compromised by the eye tracker, making tests under almost real conditions possible.

Use of Eye Tracking in the Media Production Group

Eye tracking makes it possible to optimize operating surfaces, determining which areas of an interface are looked at by users most often and which areas are possibly not perceived. Based on this knowledge, operating surfaces can be optimized, and, for example, frequently used functions of software can be moved to the area which is most often in the vision field of the user.
