Tacsel: Shape-Changing Tactile Screen applied for Eyes-Free Interaction in Cockpit
Résumé
Touch screens have become widely used in recent years. Nowadays they have been integrated on numerous electronic devices for common use since they allow the user to interact with what is displayed on the screen. However, these technologies cannot be used in complex systems in which the visual attention is very limited (cockpit manipulation, driving tasks, etc.). This paper introduces the concept of Tacsel, the smaller dynamic element of a tactile screen. Tacsels allow shape-changing and flexible properties to touch screen devices providing eyes-free interaction. We developed a high-resolution prototype of Tacsel to demonstrate its technical feasibility and its potential within a cockpit context. Three interaction scenarios are described and a workshop with brainstorming and video-prototyping is conducted to evaluate the use of the proposed Tacsel in several cockpit tasks. Results showed that interactive Tacsels have a real potential for future cockpits. Several other possible applications are also described, and several advantages and limitations are discussed.
