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.

“…3 right), the tactile feedback is always directed to the visual working area of the user, and its range is adequate (the convenient reach volume of an arm). If the array is in a fixed position [25], it limits the working range. Cues onto the face of an HMD user are also possible [16].…”

“…Hasegawa and Shinoda [11] presented a multiunit ultrasound phased array that produced tactile sensations 1m away from the surface of the array, greatly increasing the distance of haptic rendering. Kervegant et al demonstrated a human-computer interaction experience that combined smart glasses and a haptic device [12] . A hybrid holographic display and ultrasound transducer array provide realistic and tangible feedback to a hologram.…”

Background Ultrasonic tactile representation utilizes focused ultrasound to create tactile sensations on the bare skin of a user's hand that is not in contact with a device. This study is a preliminary investigation on whether different ultrasonic haptic rendering methods have an impact on the perceptual threshold. Methods This study conducted experiments with the adaptive step method to obtain participants' perceptual thresholds. We examine (1) whether different parts on the palm of the hand have different perceptual thresholds; (2) whether the perceptual threshold is different when the ultrasonic focus point is stationary and when it moves in different trajectories; (3) whether different moving speeds of the ultrasonic focus point have an influence on the perceptual threshold; and (4) whether the addition of a DC offset to the modulating wave has an impact on the perceptual threshold. Results The results show that the center of the palm is more sensitive to ultrasonic haptics than the fingertip; compared with a fast-moving focus point, the palm is more sensitive to a stationary and slow-moving focus point. When the modulating wave has a DC offset, the palm is sensitive to a much smaller modulation amplitude. Conclusion For the future ultrasonic tactile representation systems, dynamic adjustment of intensity is required to compensate the difference in perceptual thresholds under different rendering methods to achieve more realistic ultrasonic haptics.

“…The technology has made significant leaps forward since its invention in 2010 [10]. It delivers advanced, multi-point mid-air tactile sensations directly onto users' hands and fingertips, allowing accurate and dynamic real time hand gesture interactions and holographic object-manipulations [11]. Moreover, recent literature has reported the use of this technology for VR interactions [12] and in-car infotainment systems [13].…”

We present a prototype demonstrator that integrates three technologies: mixed reality head mounted displays, wearable biosensors, and mid-air haptic projectors to deliver an interactive tactile experience with a bio-hologram. Users of this prototype are able to see, touch and feel a hologram of a heart that is beating at the same rhythm as their own. The demo uses an Ultrahaptics device, a Magic Leap One Mixed Reality headset, and an Apple Watch that measures the wearer's heart rate, all synchronized and networked together such that updates from the wristband dynamically change the haptic feedback and the animation speed of the beating heart thus creating a more personalised experience.
