When you see a heatmap for the first time, it is easy to feel intimidated by the technology and forget to critically evaluate what you are seeing. Harry's UX LX 2010 talk gives a heads-up on how to think critically about eye tracking: it shows where users looked, not what they did or why; it misses peripheral vision and brief glances; and results only make sense against a clear research question.

Usability TestingUsability testing reveals where people struggle while attempting realistic tasks with a prototype or service. In a moderated session, a researcher observes the participant and may ask them to explain their thinking. Use it to investigate confusing language, layouts or interactions and identify improvements. Agree research questions, recruit likely users and prepare believable tasks that do not reveal the solution. Explain that the service is being tested, then mostly watch and listen rather than guiding participants. Record observations and follow up on unclear behaviour. Plan accessible sessions, including participants’ own assistive technology when appropriate.
