Space is Part of the Product: Using AttrakDiff to Identify Spatial Impact on User Experience with Media Façades

In HCI research, the user experience (UX) in response to interactive public installations, media façades and displays is frequently evaluated using the AttrakDiff questionnaire. The latent assumption is that its result is invariant to changes over time, environment and context. While previous research analyzed the impact of time as single variable, studies have not yet investigated environment or context. At the same time, researchers and practitioners appear to have the intuitive assumption that interaction with any media façade is best experienced from the middle at a distance which is 'convenient' to watch. We investigated the temporal, spatial and contextual impact on AttrakDiff's user rated pragmatic and hedonic qualities and attractiveness. Analysis revealed that interacting from different positions in close vicinity (<15m) parallel to the media façade did not significantly influence UX. Ratings were mostly invariant when conducting the study at two different lived environments; and short-timed repeated measures using AttrakDiff did not cause a decline in participants' ratings.
