Design psychology testing centre
The design psychology testing centre's approach sets itself apart from the methods normally used to measure user behaviour, combining known ethnographic methods with the latest psychophysiological measurement technology.
The interesting thing about the technologies used for psychophysiological measurements is that they are portable. This means that today, these measurements can be taken in users' natural environments, whereas it was previously necessary for them to visit a laboratory.
Psychophysiological measurementsThe centre uses a variety of technologies, including:
- Eye tracking
Glasses and software that capture and analyse what we look at, in what order, and for how long. This can provide information about what test subjects look at and what they skip over. Among other applications, eye tracking is used to investigate how we operate machinery, how we read manuals, how we find a path through a space, and what captures our interest.
Measures sweat production in (e.g.) the hands. This is an indicator of how the body prepares itself to respond to a stressful situation.
- Facial expression analysis
A webcam is used to record and identify small changes in our facial expressions, prompted by (e.g.) emotional impressions.
Sensors and software that measure our mental workload when we operate devices or machinery, or our excitement and engagement when we select products or find ourselves in the middle of a monotonous workflow.
Measures heart rhythms. This can provide insight into subconscious reactions to stimuli, such as a person's emotional state (neutral, happy, stressed, sad) in different situations.
