Audio-Tactile Feedback Mechanisms for Multi-Touch HMI Panels of Production Engineering Systems

摘要

Over the last decade, touch screen interaction has been gaining wide acceptance in information technology and daily consumer products. Accordingly, first approaches to applications and devices for production engineering systems are now entering the market. Although they employ intuitive user concepts, touch screens for industrial HMI panels still lack hap-tic feedback. Since operators observes the machining process and machine handling is often done blind, false handling or wrong input signals may damage machines or injure human workers. With this in mind, this paper presents a haptic feedback mechanism for touch-based interaction. A user evaluation performed on the developed system unveils increasing input security and thus an enhanced user experience.
