“…Beside directional patterns, previous work explored tactile simulation patterns of different force, frequency and three-dimensional shapes. HapCube used three voice-coil actuators to give tangential and normal pseudo-force feedback at the fingertip [28]. WAVES used voice coil actuators on the fingers to give three-dimensional translation and rotation cues with asymmetric vibration on multiple fingers [10].…”

Figure 1: Active PinScreen is a tactile feedback grid that can be mounted on the back of a mobile device to give spatio-temporal direction information over multiple fingers, synchronised with the digital content on the phone's touchscreen. The main image shows a close-up view of the device's 1 mm diameter pins. The small nature of the Active PinScreen (as seen in the schematic inset to the right; blue highlighted area corresponding to main photo) affords the ability to fit comfortably on the back of a standard touchscreen device to provide high-precision feedback to multiple fingers at once.

“…After the first haptic device was proposed by Rosenberg in 1992 to enhance usability while remotely controlling surgical robots [1], researchers in haptics and human-computer interaction (HCI) have explored its feasible form for end-user touch interaction [2][3][4][5][6][7]. Various types of haptic devices have been proposed, ranging from heavy and grounded devices with robot arms [1,8] to exoskeletons [9][10][11], braille-type tactile displays [12], as well as light and embedded devices that use vibrations [2,[13][14][15] or electroadhesion [16]. These devices reproduce rich haptic sensations, such as repulsive forces [8,[17][18][19] or frictional forces [15,20], while touching an object, or its elasticity [15,17,21] or texture [22][23][24][25][26] in a manner.…”

“…To reproduce a more plausible haptic sensation beyond the simple buzzing sensation while maintaining a relatively simple mechanical structure, haptic devices have been developed to operate in multiple degrees of freedom (DOFs) or multiple dimensions; they are required to comprise multiple actuators and sophisticated mechanical structures. HapCube [15] is a small tactile feedback device (24 mm × 24 mm × 20 mm) that generates multidimensional vibrotactile feedback but has a complicated x-y stage structure and multiple actuators. Schorr and Okamura [7] developed a finger-worn tactile device that delivers 3-DOF tactile feedback to a user's finger pad, and Mintchev et al [3] designed a thin joystick (3 mm thickness) with an origami structure that creates 3-DOF force feedback.…”

This study aims to explore a feasible form of a haptic device for common users. We propose HAPmini, a novel graspable haptic device that enhances the user’s touch interaction. To achieve this enhancement, the HAPmini is designed with low mechanical complexity, few actuators, and a simple structure, while still providing force and tactile feedback to users. Despite having a single solenoid-magnet actuator and a simple structure, the HAPmini can provide haptic feedback corresponding to a user’s 2-dimensional touch interaction. Based on the force and tactile feedback, the hardware magnetic snap function and virtual texture were developed. The hardware magnetic snap function helped users perform pointing tasks by applying an external force to their fingers to enhance their touch interaction performance. The virtual texture simulated the surface texture of a specific material through vibration and delivered a haptic sensation to users. In this study, five virtual textures (i.e., reproductions of the textures of paper, jean, wood, sandpaper, and cardboard) were designed for HAPmini. Both HAPmini functions were tested in three experiments. First, a comparative experiment was conducted, and it was confirmed that the hardware magnetic snap function could increase the performance of pointing tasks to the same extent as the software magnetic snap function could, which is commonly used in graphical tools. Second, ABX and matching tests were conducted to determine whether HAPmini could generate the five virtual textures, which were designed differently and sufficiently well for the participants to be distinguished from each other. The correctness rates of the ABX and the matching tests were 97.3% and 93.3%, respectively. The results confirmed that the participants could distinguish the virtual textures generated using HAPmini. The experiments indicate that HAPmini enhances the usability of touch interaction (hardware magnetic snap function) and also provides additional texture information that was previously unavailable on the touchscreen (virtual texture).

“…Numerous research devices have shown that there is value in providing rich haptic feedback to the fingertips during manipulation (Johansson and Flanagan, 2009;Schorr and Okamura, 2017;Hinchet et al, 2018;Lee et al, 2019), texture perception (Chan et al, 2021), stiffness perception (Salazar et al, 2020), and normal and shear force perception (Kim et al, 2018;Preechayasomboon et al, 2020). Although these devices may render high fidelity haptic feedback, they often come at the cost of being tethered to another device or have bulky electronics that impede the wearability of the device and ultimately hinder immersion of the VR experience.…”

We introduce Haplets, a wearable, low-encumbrance, finger-worn, wireless haptic device that provides vibrotactile feedback for hand tracking applications in virtual and augmented reality. Haplets are small enough to fit on the back of the fingers and fingernails while leaving the fingertips free for interacting with real-world objects. Through robust physically-simulated hands and low-latency wireless communication, Haplets can render haptic feedback in the form of impacts and textures, and supplements the experience with pseudo-haptic illusions. When used in conjunction with handheld tools, such as a pen, Haplets provide haptic feedback for otherwise passive tools in virtual reality, such as for emulating friction and pressure-sensitivity. We present the design and engineering for the hardware for Haplets, as well as the software framework for haptic rendering. As an example use case, we present a user study in which Haplets are used to improve the line width accuracy of a pressure-sensitive pen in a virtual reality drawing task. We also demonstrate Haplets used during manipulation of objects and during a painting and sculpting scenario in virtual reality. Haplets, at the very least, can be used as a prototyping platform for haptic feedback in virtual reality.
