“…Furthermore, as flexible displays become increasingly available, this approach to volumetric haptics could potentially be integrated within a display. Much of the current focus of volumetric haptics is focused on VR and AR environments [55]. A fascinating suggestion is the idea that volumetric haptics may be a necessity in the field of tele-surgery, where a surgeon needs precise feedback to operate precision tools remotely [56][57][58].…”

In this paper, we report a method of implementing a universal volumetric haptic actuation platform which can be adapted to fit a wide variety of visual displays with flat surfaces. This platform aims to enable the simulation of the 3D features of input interfaces. This goal is achieved using four readily available stepper motors in a diagonal cross configuration with which we can quickly change the position of a surface in a manner that can render these volumetric features. In our research, we use a Microsoft Surface Go tablet placed on the haptic enhancement actuation platform to replicate the exploratory features of virtual keyboard keycaps displayed on the touchscreen. We ask seven participants to explore the surface of a virtual keypad comprised of 12 keycaps. As a second task, random key positions are announced one at a time, which the participant is expected to locate. These experiments are used to understand how and with what fidelity the volumetric feedback could improve performance (detection time, track length, and error rate) of detecting the specific keycaps location with haptic feedback and in the absence of visual feedback. Participants complete the tasks with great success (p < 0.05). In addition, their ability to feel convex keycaps is confirmed within the subjective comments.

“…AIREAL [98] is designed to use a vortex, a ring of air that can travel large distances to hit a user's skin. Ultrasound devices [99]- [101] modulate the activation of an array of ultrasound transducers to create focal pressure around the user, which can give the user tactile cues of gestures, textures, and virtual objects.…”

Interacting with virtual objects with haptic feedback directly using the user's hand (hand-based haptic interaction) has attracted increasing attention. Due to the high degrees of freedom of the hand, compared with tool-based interactive simulation using a pen-like haptic proxy, hand-based haptic simulation faces greater challenges, mainly including higher motion mapping and modeling difficulty of deformable hand avatars, higher computational complexity of contact dynamics, and nontrivial multi-modal fusion feedback. In this paper, we aim to review key computing components for hand-based haptic simulation, and draw out major findings in this direction while analyzing the gaps toward immersive and natural hand-based haptic interaction. To this end, we investigate existing relevant studies on hand-based interaction with kinesthetic and/or cutaneous display in terms of virtual hand modeling, hand-based haptic rendering, and visuohaptic fusion feedback. By identifying current challenges, we finally highlight future perspectives in this field.
