The research framework of eye-tracking based mobile device usability evaluation

Eye-tracking is a valuable tool for mobile device usability research, but there are still many challenges about how to create good usability evaluation, such as the accurate enough eye-movement data from the small view angle on a real mobile device. This paper presents one research framework, which combines the remote eye-tracker and portable eye-tracker for both quantitive and qualitative evaluation. An example is reported in which a mobile device user interface is analyzed in on-screen simulation using a remote eye-tracker, and with the real device using a portable eye-tracker. We get the usability problem lists and design advices at the end. It illustrates the feasibility and effectiveness for the proposed research framework.
