Sensual Evaluation Instrument
Different shaped objects are used by users during a usability test to express how they feel. After the test, an interview is conducted to interpret the results.
The participant interacts with a system and he has an easy access to physical objects with different shapes (spiky, smooth). When emotions arise during interaction, he can pick one of the shapes to express the emotion.
Allows to study ambiquity. Picking an object is not as disturbing for the interaction as many other forms of self-reporting. Non-verbal.
Not easy to analyse.
