Methods for pair evaluations

Compared to discussions with a researcher, discussions with a friend may reveal very different perspective of user experience. There are a few methods in our collection that allow inviting pairs of users to the evaluation, instead of single users.


Two friends explore a product/concept together and discuss about it (with or without a moderator). Videorecording is used especially when no moderator is present.


Emotional responses elicited by consumer products are difficult to verbalize because their nature is subtle (low intensity) and often miemotional response at the same time). As a result, these emotions are difficult to measure with verbal questionnaires. Instead of relying on the use of words, respondents can report their emotions with the use of cartoon drawings of facial expressions. The Emofaces can be used in internet surveys, formal interviews, and in qualitative interviews.

Experience clip

When collecting data about user experience evoked by mobile acpplications, one user uses the mobile application to be evaluated, and another uses a mobile phone to shoot clips about usage and expressions of experiences. The two users know each others, and interact in natural situations and environment without presence of researcher. The method takes use of the social interaction between the user and someone the user knows well.

Private camera conversation

To avoid interviewer bias, the participant goes to a booth and talks to the camera about the topics given to her/him. Videorecording may bring out more hedonic aspects than with an interviewer, because participants want to act rationally with the interviewer.

Resonance testing

Resonance testing is a method to validate product concepts againts a set of experiential goals. It is primarily intended for use with physical products

Semi-structured experience interview

Face to face or online interview. Ask people what they think, feel, experience
