Anthony, L., Stofer, K.A., Luc, A., and Wobbrock, J.O. 2016. Gestures by Children and Adults on Touch Tables and Touch Walls in a Public Science Center. Proceedings of the ACM Interaction Design and Children Conference (IDC’2016), Manchester UK, 22 Jun 2016, pages 344-355.
“Research on children’s interactions with touchscreen devices has examined small and large screens and compared interaction to adults or among children of different ages. Little work has explicitly compared interaction on different platforms, however. Large touchscreen displays can be deployed flat, as in a table, or vertically, as on a wall. While these two form factors have been studied, it is not known what differences may exist between them. We present a study of visitors to a science museum, including children and their parents, who interacted with Google Earth on either a touch table or a touch wall. We compare the types of gestures and interactions attempted on each device and find several interesting results, including: users of all ages tend to make standard touchscreen gestures on both platforms, but children were more likely than adults to try new gestures. Users were more likely to perform two-handed, multi-touch gestures on the touch wall than on the touch table. Our findings will inform the design of future interactive applications for each platform.”
