The Eyegaze Trace Suite is a collection of programs that capture a subject’s gaze using LC Technologies' Eyegaze System while presenting stimulus to the subject. The gaze and the stimulus are linked so they can be replayed and studied at a later time.

 

 

The Trace Suite consist of four programs:
EGTraceDynamic, EGTraceMedia, EGTraceImage and EGTraceText.

 

EGTraceDynamic captures the subjects' gaze movements as they perfom any type of function on the computer. The output presents the gaze point superimposed over a video like sequence of the computer screen activity (incorporating keyboard and mouse activity) that the subjects' have performed. This type of data is useful for evaluating user interaction with websites and program interfaces.

 

 

 

EGTraceMedia captures gaze information while playing a moving picture, either a DVD or an MPEG clip. The output presents the gazepoint of the subject superimposed over a replay of the media. This type of data is useful for evaluating TV commercials, movies, as well as evaluating viewers' gaze movements over video images captured by the evaluator's camera.

 

 

 

EGTraceImage captures gaze information while presenting a static image.  This has been used for evaluating print advertisements or other static information presentations.

 

 

 

 

 

 

EGTraceText presents text to the subject while capturing the gaze (fixations, saccades) movement through the text. Any text can be used and the program outputs have been used for reading evaluations, studying learning diabilities, such as dyslexia, and measuring gaze relationship to retention.

 

 

 

 

Note:The functionality of the EGTraceText and EGTraceImage programs are currently bundled in the Trace program that ships with the Eyegaze Analysis System.
