“…As far as it concerns the technological aspect, the use of thimble-factor devices guarantees high portability and wearability of the system, it reduces power consumption increasing the battery lifetime. The main novelties that our approach introduces with respect to the currently available solutions can be summarized as follows: i) the hand is directly controlled displaying cues in the most sensitive location [26]; ii) no encumbering devices prevent the user's hand to be free; iii) the hand orientation is suggested independently from other body parts, increasing the haptic guidance capability; iv) human arm singolarities are avoided by charging the inverse kinematics computation to the brain instead of to an algorithm; v) the approach can be combined with any hand tracking system, like camerabased (Vicon, Optitrack, LeapMotion), inertial-based ( [27], [28]) and fabric-based (Cyberglove) devices. In conclusion, we believe that the proposed system paved the way for the development of more complex systems.…”

In this work, we propose a novel method for hand guidance, combining grasping metaphor and wearable haptics. To guide the hand towards the desired orientation, the system generates vibrations exploiting the grasp theory, asking the user to align the perceived wrench with the gravity. To evaluate the system and demonstrate its potentiality, different vibrotactile feedback approaches have been tested. Both constant and errordepending vibration intensities were considered as feedback methods. Experimental results confirmed the capability of the proposed approach in guiding the hand of the users towards target orientations in a limited time with high accuracy. Users' experience feedback, supported by the statistical analysis of the data, shows that providing information about the actual orientation error is crucial to accomplish the task in minor time.

“…Thus, most haptic thimbles are designed relying on these principles, and based on two main approaches: moving platform mechanisms [3], [7], [68]- [78], and shearing belt mechanisms [79]- [82]. Other less common approaches are moving tactors [83], and systems with electrical [84], thermal [76], vibration [85], [86] and pneumatic [87] stimulation.…”

“…Most of the previously described finger-worn haptic devices focuses on providing tactile stimuli to the most sensitive part of the skin -the fingerpad. Gaudeni et al [86] presented a haptic ring that provides a vibrotactile feedback, and can be worn on three different locations: fingertip, dorsal side of proximal phalanx, and wrist. The device is composed of a VCA enclosed in a 3D-printed housing that can be fixed to a limb.…”

“…The device is composed of a VCA enclosed in a 3D-printed housing that can be fixed to a limb. In [86], it was concluded that the vibrotactile cues provided by the haptic ring on the proximal phalanx are sufficient for a user to distinguish between different surface textures. Thus, this type of design can help freeing the fingertips for other tasks.…”

Haptic Devices: Wearability-Based Taxonomy and Literature Review

In the last decade, several new haptic devices have been developed, contributing to the definition of more realistic virtual environments. An overview on this topic requires a description of the various technologies employed in building such devices, and of their application domains. This survey describes the current technology underlying haptic devices, based on the concept of "wearability level". More than 90 devices, newly developed and described in scientific papers published in the period 2010-2021, are reviewed, which provide either haptic illusions or novel haptic feedback for teleoperation, entertainment, training, education, guidance and notification. As a result, the analyzed systems are divided into grounded, hand-held and wearable devices; the latter are further split into exoskeletons and gloves, finger-worn devices, and arm-worn devices. For the systems in each of these categories, descriptions and tables are provided that analyze their structure, including device mass and employed actuators, their applications, and other characteristics such as type of haptic feedback and tactile illusions. The paper also provides an overview of devices worn in parts of the human body other than arms and hands, and precisely haptic vests, jackets and belts, and haptic devices for head, legs and feet. Based on this analysis, the survey also provides a discussion on research gaps and challenges, and potential future directions.INDEX TERMS haptic devices, virtual reality interfaces, kinesthetic feedback, tactile feedback, haptic illusions.

“…The developed device provoked the sensation of index finger and thumb movements during a tip grasp of the stiff device of an object seen in an HMD. In this work, we aim in table-top haptic feedback device that excites the feeling of elbow movement [12], [13] were conducted to create a vice-versa simulation (e.g. illusion of fingertips perception while simulating wrist or forearm).…”

With the proliferation of haptic interfaces, the vibrotactile capabilities are accessible to a substantial number of end-users allowing a more realistic experience with Virtual Reality. Currently, the primary use of this vibrotactile feedback is to provide additional support to visual interaction via prehensile object manipulation using fingers. Nevertheless, haptic stimuli can be also applied for non-prehensile interaction that involves movements of the elbow joint. In this paper, we have designed and evaluated a vibrotactile device to investigate the effect of haptic stimuli, applied onto the fingertips, on a sensation of elbow displacements. The vision-driven displacement produced by the pseudo-haptics effect is then amplified by the vibrotactile stimuli. The experimental platform consists of a voice-coil actuator and a force sensor for generating mechanical vibrations at fingertips. The efficacy of the approach was validated in experiments with human subjects. The results show that the combination of pseudo-haptic and haptic illusion effects can be used to render various soft and rigid virtual objects.
