Usability Testing of the Interaction of Novices with a Multi-touch Table in Semi Public Space

Touch-sensitive devices are becoming more and more common. Many people use touch interaction, especially on handheld devices like iPhones or other mobile phones. But the question is, do people really understand the different gestures, i.e., do they know which gesture is the correct one for the intended action and do they know how to transfer the gestures to bigger devices and surfaces? This paper reports the results of usability tests which were carried out in semi public space to explore peoples’ ability to find gestures to navigate on a virtual globe. The globe is presented on a multi-touch-table. Furthermore, the study investigated which additional gestures people use intuitively as compared to the ones which are implemented.
