Gebruikersschetsen: een aanvullende methode

This paper describes the use of sketches of drawings created by participants in the process of usability evaluation. In this case, we draw upon our experiences from a user-based study of car stereo systems and control configurations. The approach, centred on 'user sketches', proved an exceptionally good means of encouraging users to express their ideas. We view the method as an augmentation of the traditional usability engineering approach. The addition of this technique means that rich qualitative data can be collected, providing further insight into users' perception of and preferences for particular configurations and means of operation of interactive devices.
