When interacting with physical objects, we receive sensory feedback about the characteristics of these objects. Specifically, the sounds resulting from touching a surface provide information about the material of the surface and about one's own touching behaviour. Current developments in interactive systems are opening up new avenues in the use and design of both physical and virtual objects. These developments have the potential to change people’s behaviours, perceptions and emotions – elements of user experience that can be measured.
This talk presents the results of a study on auditory feedback as example of how research methods from cognitive psychology and human computer interaction can be used to evaluate these potential changes. This research may inform the design of physical and virtual objects and help enhance everyday user experiences.
