“…Haptic interfaces are widely used due to their verified effect in enhancing the presence and the task-performance in the virtual reality (VR) or augmented reality (AR) (Rosenberg, 1995 ; Sallnäs et al, 2000 ; Hecht et al, 2006 ). Generally, haptic interfaces can be categorized depending on their grounding locations (Prattichizzo et al, 2019 ): grounded devices (Massie and Salisbury, 1994 ), non-grounded devices (Choi et al, 2018 ). In early days, various types of grounded haptic interfaces were developed and still dominantly utilized in robotic fields owing to its accurate force application and sufficient stiffness range.…”

Recent advancements in virtual reality and augmented reality call for light-weight and compliant haptic interfaces to maximize the task-performance interactivity with the virtual or extended environment. Noting this, we propose a haptic glove using a tendon-driven compliant robotic mechanism. Our proposed interface can provide haptic feedback to two fingers of a user, an index finger and a thumb. It can provide both cutaneous and kinesthetic feedback to the fingers by using the tendon-driven system. Each actuator is paired with a force sensor to exert the desired tension accurately. In order to optimize the perception of the kinesthetic feedback, we propose a perception-based kinesthetic feedback distribution strategy. We experimentally measured the force perception weight for peripheral interphalangeal (PIP) and metacarpophalangeal (MCP) joints. We observed no significant difference in the force perception between the two joints. Then, based on the obtained weights, our proposed force distribution method calculates the force for each joint. We also evaluated the effect of additional cutaneous feedback to the kinesthetic feedback, on the force perception at the fingertip. The experimental result has shown that additional cutaneous feedback has significantly increased the sensitivity of the human perception. Finally, we evaluated our proposed system and force distribution algorithm by conducting a human subject test. The experimental result indicates that the availability of the cutaneous feedback significantly improved the perceived realism and acuity of the contact force.

“…Wearable haptic interfaces are generally designed to be compact and comfortable so as to not impede the movement of users [63]. This is why compared to other haptic interfaces, wearable systems are mainly used to aid in patient rehabilitation to reduce joint loads, identify movement disorders and improve walking strength and stability [64], [65].…”

The sense of touch (haptics) has been applied in a few areas such as tele-haptics, tele-medicine, training, education, and entertainment. As of today, haptics is currently used and explored by researchers in more areas. These can span from both multi-disciplinary and even inter-disciplinary areas as well. The utilization of haptics is also enhanced with other forms of media such as audio, video, and smell. For example, haptic use is prevalent in virtual reality environments to increase the immersive experience for users. However, while there is significant progress pertaining to haptic interfaces throughout the years, there are still many challenges that limit this progression. Therefore, this review highlights haptic interfaces for virtual reality ranging from wearables, handhelds, encountered type, props and mid-air. We discuss and summarize these approaches and along with interaction domains such as skin receptors, object properties and force. Furthermore, design challenges for each interface are also highlighted along with existing research gaps.INDEX TERMS haptic interfaces, human-computer interaction, virtual reality.

“…Wearable technology has evolved with the integration of haptic feedback, resulting in enhanced sensory experiences and increased interaction with digital information. [1] In particular, the delivery of tactile cues in wearables has proven instrumental in enhancing user interactions, [2][3][4] increasing perception in virtual environments, [5][6][7][8] augmenting tasks such as robotic teleoperation, [9][10][11][12][13] and facilitating wearable-and prostheticbased rehabilitation. [14][15][16][17][18] This spread of applications underscores the wide interest and investment in the development of information-dense haptic wearables in the research and commercial spaces.…”

Wearable haptic devices transmit information via touch receptors in the skin, yet devices located on parts of the body with high densities of receptors, such as fingertips and hands, impede interactions. Other locations that are well‐suited for wearables, such as the wrists and arms, suffer from lower perceptual sensitivity. The emergence of textile‐based wearable devices introduces new techniques of fabrication that can be leveraged to address these constraints and enable new modes of haptic interactions. This article formalizes the concept of “multiscale” interaction, an untapped paradigm for haptic wearables, enabling enhanced delivery of information via textile‐based haptic modules. In this approach, users choose the depth and detail of their haptic experiences by varying their interaction mode. Flexible prototyping methods enable multiscale haptic bands that provide both body‐scale interactions (on the forearm) and hand‐scale interactions (on the fingers and palm). A series of experiments assess participants’ ability to identify pressure states and spatial locations delivered by these bands across these interaction scales. A final experiment demonstrates the encoding of three‐bit information into prototypical multiscale interactions, showcasing the paradigm's efficacy. This research lays the groundwork for versatile haptic communication and wearable design, offering users the ability to select interaction modes for receiving information.
