An Evaluation of Substrates for Tactile Displays: Scanning Speed and User Preferences
نویسندگان
چکیده
This study deals with the suitability of substrates for tactile maps and diagrams for visually impaired people. Visually impaired and sighted participants scanned symbol arrays by touch on 7 different substrates, including papers, plastics and aluminium. In general, papers were rougher than plastics and aluminium. Search time and participants’ preferences were recorded. In general, rougher substrates were scanned faster than smoother substrates. Moreover, the majority of participants preferred rough substrates over smooth ones.

In this work we propose a wearable solution for boundary detection (using ultrasonic range finders) and notification (via tactile actuators) under conditions of poor visibility. “Personal Radar” is not ’yet another’ belt-like tactile feedback system used for walking navigation, the unique feature of our obstacle scanning and notification solution is, that it is self-contained and fully self-gov...
متن کاملAudiotactile Feedback Design for Touch Screens
The use of touch sensitive displays and touch surfaces is just emerging and they are more and more replacing physical buttons. If a physical button is pressed, audio and tactile feedback confirms the successful operation. The loss of audiotactile feedback in touch sensitive interfaces might create higher input error rates and user dissatisfaction. Therefore the design and evaluation of suitable...
متن کاملGuidelines for the Use of Vibro-Tactile Displays in Human Computer Interaction
Vibro-tactile displays convey messages by presenting vibration to the user’s skin. In recent years, the interest in and application of vibro-tactile displays is growing. Vibratory displays are introduced in mobile devices, desktop applications and even in aircraft [1]. Despite the growing interest, guidelines on the design of vibro-tactile displays are still lacking. Existing guidelines are mai...
