Abstract

Satisfaction is a dimension of usability for which quantitative metrics cannot be calculated during user interactions. Measurement is subjective and depends on the ability to interpret questionnaires and on the memory of the user. This paper represents an attempt to develop an automatic quantitative metric of satisfaction, developed using a Brain Computer Interface to monitor the mental states (Attention/Meditation) of users. Based on these results, we are able to establish a correlation between the state of Attention and the users’ level of satisfaction.

Keywords: Brain Computer Interface, Mindwave, satisfaction, usability evaluation
