A Survey of Mid-Air Ultrasonic Tactile Feedback

This paper contains a succinct survey on the recent major advances in contactless ultrasonic tactile feedback. It is a haptic technology which enables easy mid-air interactions with rich multisensory feedback and creates effects which are otherwise impossible. It can become a disruptive technology for multimedia interfaces, applications, and mobile computing. We summarize and discuss the advantages, problems and applications of the technology. This survey provides an introduction to the topic for anyone interested in applying or researching it.
