Physiology as a Tool for UX and Usability Testing

The purpose of this degree project is to investigate how physiological measures, such as heart rate, skin conductance and EEG (i.e. electrical brain activity), may be useful in UX and usability testing.

One physiological research method is discussed in more detail, i.e. the measurement of pupil size, or pupillometry. The study seeks to answer the following questions: 1.What can we find out about human emotions and cognition by measuring and analyzing variations in pupil size? 2. What can we find out about human emotions and cognition by using other popular physiological measurement methods? 3. How does pupillometry compare to other physiological measures for the purpose of UX and usability testing?

What’s the problem? Studies on identifying usability problems in user tests

This is the kind of muttering researchers in a usability lab often hear when users are having trouble performing a given task with the product or prototype being tested./strong>

The activity the researcher is performing in this situation is called conducting a usability test: a test to find out what difficulties people run into when they are trying to use a (newly designed) product. During the usability test and in inter views or analyses afterwards, the researcher will try to figure out why the user experienced a given difficulty and what product characteristics contributed to that. Once the problem is understood, a designer can attempt to redesign the product’s characteristics so that the chance of future users running into the same difficulty is minimized.
