“Design is less and less about solving problems, testing less and less about eliminating frustration. It’s all becoming more and more about making a good experience for users… Now it’s not good enough to just be usable. The design has to fit into peoples’ lives.

Eyetracking Metrics for Usability Studies

Eyetracking Metrics for Usability Studies

Eyetracking has been a heavily debated subject within the field of User Experience Design and in particular within the Usability community.  Some argue that eye fixations don’t necessarily equal attention or understanding, and question whether eyetracking should be used to support traditional usability findings.  However, the other side argues that when eye tracking data is used in conjuction with traditional usability techniques, it can provide deep insight into where participants look during a task which can help us determine why usability issues are present within an interface.

Usability testing is a means of understanding the goodness of a design’s fit to the intended users’ problems

“Usability testing should not be a stage gate in your design and development process. It should be a tool with which to gather helpful, diagnostic information from your target users. It’s a means of understanding the goodness of a design’s fit to the intended users’ problems.” – Paul J. Sherman
