Abstract
The paper presents the user experience evaluation of Squeeze Me, an interactive cover for tablet and smartphone that enables continuous and expressive interaction with electronic devices. The cover has been used to implement ”Squeeze to zoom”, a mobile application to zoom in and out while taking a photograph from a tablet. The experience of use was evaluated in the short and medium term, comparing the Squeeze Me interaction modality with classic modalities for zooming in and out commonly available on tablets and smartphones. The evaluation process was conducted using AttrakDiff [3] a questionnaire that measures hedonic stimulation and identity, as well as pragmatic qualities and attractiveness of software products. Participants were asked to try out different interaction modalities for comparison in the short-term (67 people) and over 4 weeks (8 people). Results obtained in the short-term evaluation reveal that “Squeeze to zoom” was awarded higher values than the classic “Slide to zoom” in the hedonic quality-stimulation and attractiveness dimensions, whilst it obtained lower values in the pragmatic quality and hedonic quality-identity. However, the experience of use changed over time. During the longitudinal study, the usability of “Squeeze to zoom” improved whilst the attractiveness of “Slide to zoom” decreases significantly. Furthermore results reveal that “Squeeze to zoom” is significantly more appreciated for its hedonic qualities and the effect is maintained over time. This study highlights the importance of evaluating the experience of use over time, a practice that is almost ignored in the literature on Experience Design.
