A UK research team created a system designed for use in public spaces that lets people feel what is on a device’s display without needing to touch a separate haptic-feedback object in the process, as is the case with most haptic approaches. University of Bristol scientists designed UltraHaptics, which , uses ultrasonic vibration to provide multiple users with mid-air haptic feedback. The system works with a phased array of ultrasonic transducers, which emit high frequency sound waves. These provide the force that generates haptic sensations for users as they view the screen. The researchers are presenting their work at the 26th annual ACM Symposium on User Interface Software and Technology this month in St. Andrews, UK.
