Paper Abstract:
|
New interaction techniques beyond mouse and keyboard were established during the last five years allowing different and multiple modalities. The aim of our work was to study how users work with a touch device, which can be used as a basis for designing natural user interfaces optimized for touch. We developed an evaluation concept for a single- versus multi-touch scenario. Applying this concept we studied users strategies, accuracy and completion times in performing the three evaluation tasks: moving virtual objects by touching, typing with a virtual keyboard and using touch menus to select options. The user tests were performed on a Microsoft Surface during the open day at our university. Results of the evaluation showed that our two user groups beginners and professionals directly profit from the natural interaction concepts of a touch interface, like for example direct manipulation, except for scenarios where a haptic feedback is helpful to minimize input errors. Both groups only differ in using a virtual keyboard due to training effects. Additional, the intuitive usage and novelty of a touch device seemed to motivate the participants in accomplishing the tasks. |
