Users research new tools - eye tracker

One, eye tracker and eye movement technology

Eye movement technology is to extract the data such as the fixation point, the fixation time, the number of fixations, the saccade distance, and the pupil size from the records of the eye movement trajectory, so as to study the intrinsic cognitive process of the individual. The eye tracker can capture human eye movement trajectory and related parameters, obtain accurate data, and provide scientific basis for research work with the help of related analysis software. The eye tracker is a sophisticated, sophisticated scientific instrument that can improve the accuracy, reliability, and practicality of modern web page research and design. The operation is simple and the subject wears a helmet connected to the eye tracker via a single-wire cable or sits naturally in front of the high-speed tester. After running the system software, the relevant data of the eye movement can be analyzed in real time, and the video is superimposed thereon. The data is eventually recorded on hard disks or external video equipment.

Second, the application of eye tracker in user research

1. Get user's browsing features

Can be used to study the habit of users browsing specific products. If eye movement studies have found that the user browses different web pages, the most common browsing mode presents the F-shaped gaze point distribution.

2. Get the user's point of interest

By analyzing the user's time of gaze, the number of fixations, and the gaze trajectory (such as jumping back) of users in each area of ​​the record, it is possible to objectively obtain the part that the user is most interested in most. For example, by tracking the user's observation of a car image, it can be known which structure of the car most attracted the user.

3. Get the user's psychological state

The combination of eye movement indicators can reflect the user's psychological state when observing the product, such as the eye movement meter can reflect the changes of the pupil, and pupil changes are important physiological and biochemical indicators of the body's emotions. If people are choosing and remembering, the frequency of eye movements is twice that of normal conditions, and the pupils will expand.

It can be seen that using the eye tracker can analyze those places that are most attractive to users and worthy of research. Of course, the eye tracker is just a test tool, and subsequent data processing and analysis work is critical.
