The Hunt for Usability: Tracking Eye Movements    

Usability testing methods have not changed significantly since the origins of the practice. Usability studies typically address human performance at a readily observable task-level, including measures like time to complete a task, percentage of participants succeeding, type and number of errors, and subjective ratings of ease of use. Certain types of questions are difficult to answer efficiently with these techniques.

The Hunt for Usability: Tracking Eye Movements

Incorporation of eye position recording into product usability evaluation can provide insights into human-computer interaction that are not available from traditional usability testing methods. We present here some thoughts on this topic which arose primarily from a CHI 99 workshop. This workshop brought together human-computer interaction designers, eye movement researchers and usability testing specialists for a discussion about how to extract information about product usability from users’ eye movements.
