What is Eye Tracking?
Eye tracking is the process of measuring either the point of gaze ("where we are looking") or the motion of an eye relative to the head. An eye tracker is a device for measuring eye positions and eye movements. Eye trackers are used in research on the visual system, in psychology, in cognitive linguistics and in product design.
Why did I choose Eye Tracking?
Eye tracking claims to have been around for over a 100 years but its improvement has significantly been noticed over the last 5 years. Early versions were built in the form of a contact lens which contained a hole for the pupil, the lens was connected to an aluminium point which tracked the eyes movements. Studies found that eye movements consisted of rapid side to side movements rather than smooth movements as previously thought.
Due to its complex and fascinating nature it led me to choose this topic within the pervasive field. In my next blog I will be discussing the different types of trackers, how and were it is used in practise as well as how it breaks the paradigm of desktop computing.
