“…The laser haptics can compensate for the intensity and spatial resolution of ultrasonic tactile feedback. Recently, research on ultrasound tactile feedback in midair has shifted to investigate different rendering methods on perception [21][22][23][24]. All of the studies in [21][22][23][24] used the methods described in [20] to evaluate the perception of ultrasound tactile feedback.…”

“…The object of this experiment was to establish a rendering algorithm for the ultrasonic phased array. Raza et al designed an algorithm to enable the UltraHaptics device to output a desired sensation [24], but only input command intensity, modulation frequency, and position of focus were considered as influencing parameters. In this experiment, besides the above input parameters, the modulation waveform and the duty ratio of the square wave were also used as influencing parameters for ultrasonic tactile feedback.…”

“…In [13], evaluated the minimum perceivable radiation force for the focal spot proposed by 70 kHz phased array was smaller than that for the 40 kHz case on average under 40 or 100 Hz modulations. The absolute threshold of perceivable ultrasonic tactile feedback was estimated by a series of psychophysical experiments [24]. Ultrasound haptic feedback has recently been applied in many scientific fields [25][26][27][28][29].…”

This paper presents a new haptics interface device based on cable-driven parallel manipulators and an ultrasonic phased array. Unlike previous studies, our method combines force and tactile feedback at the same time. It consists of two main parts: force feedback generated by cable tension and tactile feedback provided by an ultrasonic phased array. While these parts have no direct interference, combining them can offer a synergistic effect on haptic perception. Through a series of experiments, the tactile rendering algorithm for this device is established. The output pressure of ultrasonic phased array is dependent on input command value, modulation frequency, modulation waveform, and the position of the focal point in the workspace. The results of psychophysical experiments are evaluated to determine the absolute threshold of perceivable ultrasonic tactile feedback when the cable-driven force acts on fingers. Finally, we carry out a test to confirm the accuracy advantage of our system in the virtual environment. The results of our study indicate that this device has a wide range of applications in the field of aerial haptic display.

Ultrasound haptics is a contactless haptic technology that enables novel mid-air interactions with rich multisensory feedback. This paper surveys recent advances in ultrasound haptic technology. We discuss the fundamentals of this haptic technology, how a variety of perceptible sensations are rendered, and how it is currently being used to enable novel interaction techniques. We summarize its strengths, weaknesses, and potential applications across various domains. We conclude with our perspective on key directions for this promising haptic technology.
