Recently, I watched a usability test, with no eye tracking, and this happened:
The participant, describing an issue, said – ”You can see here how … “.
In the observation room my client and I had absolutely no idea what he was talking about! We couldn’t see where his finger was pointing at the screen!
If we had the eye tracker running we could have easily seen what he was talking about, because, as he described the issue, he would have been looking at that exact spot on the screen. Seeing this real time video footage would have added so much more value to our experience as observers.
I can’t understand how people can do usability testing without eye tracking!
