New whitepaper: Retrospective Think Aloud and Eye Tracking

rta_whitepaperWe are finally releasing the white paper explaining the results from a small research project we did this summer at Tobii where we compared the value of using Retrospective Think Aloud (RTA) in web usability research. I have previously posted the results from the study here on my blog. The main finding was that using eye tracking results as a cue during the post task interview stimulated users to talk much more and produce much more interesting comments.


Retrospective Think Aloud and Eye Tracking – Comparing the value of different cues when using the retrospective think aloud method in web usability testing

Research has shown that incorporating eye tracking in usability research can provide certain benefits compared with traditional usability testing. There are various methodologies available when conducting research using eye trackers. This paper presents the results of a study aimed to compare the outcomes from four different retrospective think aloud (RTA) methods in a web usability study: an un-cued RTA, a video cued RTA, a gaze plot cued RTA, and a gaze video cued RTA. Results indicate that using any kind of cue produces more words, comments and allows participants to identify more usability issues compared with not using any cues at all. The findings also suggest that using a gaze plot or gaze video cue stimulates participants to produce the highest number of words and comments, and mention more usability problems.
