Non-Visual Feedback Cues for Pen Computing
Selina Sharmin, Grigori Evreinov, Roope Raisamo · 2005
The aim of this work is to present a novel stylus with embedded vibro-tactile actuator and an empirical pilot study on nonvisual feedback cues, tactile and sound, used when a graphical trail is inspected. The study showed that tactile feedback took less time than sound feedback to complete the task. In addition, participants preferred tactile feedback to sound during blind inspection of a trail. These results can be used for further development of novel diagrammatic tools and pen-based input techniques especially for physically challenged users.
