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.

“…For instance, the virtual environments used for evaluating the finger-feedback device hRing [8] and an asymmetric 3-RSR wearable device [9], both consist of a simple pick-and-place task. The virtual environment designed for the ferrofluid based haptic device [10] was used to discriminate the curvature and vibrational feedback. However, factors such as dimensions of virtual objects, distance between source and target, tracking mechanism, and simulation software used, to name a few, are completely different.…”

“…In this paper we propose ViESTac, a first approach to design a tactile device-agnostic multimodal VR 2 Our VR suite aims to serve as a benchmark for evaluating and comparing fingertip-wearable tactile devices primarily. In the following we present the design of the virtual suite, a pilot study with two tactile devices, the FingerTac [21] and a ferrofluid based tactile device [10], and suggest some directions for future research. Please note that for the remainder of the paper, the ferrofluid based tactile device shall be addressed as FerroVibe.…”

Research and development of telerobotic systems supplemented by haptic feedback for future planetary exploration missions has gained significant importance in the past decade. Major space agencies endeavor to deploy such systems before sending humans to the surface of unknown or unexplored celestial bodies. Astronauts control these telerobotic systems from remote locations, such as an orbital space station. Haptic feedback for teleoperating the robots in outer space is extremely important, not only to improve user immersion and task performance, but also to improve our understanding of surface properties. At the same time, for spaceflight, making use of compact, light-weight and robust devices are preferred for precise tactile feedback from telemanipulation tasks. In this paper, we introduce "ViESTac", a first attempt to develop a generic VR suite to be able to evaluate and compare fingertipwearable tactile devices. Applications of such a suite include, but are not limited to allowing teleoperators to judiciously choose suitable tactile devices for a particular task. To account for the wide variety of existing fingertip-wearable tactile devices and their display capabilities, the suite contains a set of virtual scenarios to investigate different tactile properties of virtual objects. It also dedicates a virtual scenario to evaluate how tactile feedback may govern the accuracy of human positioning in standard tasks. This proposed suite is advocated by a pilot study with 13 participants and two distinct state-of-theart tactile devices. Results of the study clearly indicate that the virtual suite can successfully cater to the need of evaluating and comparing fingertip-wearable tactile devices.

“…The device was later upgraded by adding a voice coil, enabling it to simultaneously deliver the virtual surface's orientation and a wide frequency bandwidth of tactile stimulation [5]. A ferro-fluid based tactile device was fabricated by Singh et al [22], that can also transmit both orientation and texture information at the same time. Although such devices are wearable, the overall structure is not compact enough to be worn on more than a couple of fingers as it obstructs the user's natural workspace.…”

FingerTac is a novel concept for a wearable augmented haptic thimble. It makes use of the limited spatial discrimination capabilities of vibrotactile stimuli at the skin and generates tactile feedback perceived at the bottom center of a fingertip by applying simultaneous vibrations at both sides of the finger. Since the bottom of the finger is thus kept free of obstruction, the device is well promising for augmented haptic applications, where real world interactions need to be enriched or amalgamated with virtual tactile feedback. To minimize its lateral dimension, the vibration actuators are placed on top of the device, and mechanical links transmit the vibrations to the skin. Two evaluation studies with N=10 participants investigate (i) the loss of vibration intensity through these mechanical links, and (ii) the effect of lateral displacement between stimulus and induced vibration. The results of both studies support the introduced concept of the FingerTac.
