“…The VR teleoperation training showed comparable results to the physical training, while the users reported that the VR training was highly realistic [18]. Importantly, their results were replicated and their system further scrutinized in a user study with an adequate sample size (N = 19) [85]. In this follow-up study of Hummel et al (2016) the significant difference was that the motor movements in VR were not facilitated by bimanual robotic hands, instead, the hands of the users were tracked, hence their hand-movements were directly mirrored in VR [85].…”

“…In this follow-up study of Hummel et al (2016) the significant difference was that the motor movements in VR were not facilitated by bimanual robotic hands, instead, the hands of the users were tracked, hence their hand-movements were directly mirrored in VR [85]. Their user study found that the electrotactile feedback substantially improved the grasping performance of the users, while it significantly decreased their workload [85]. These results hence appear to replicate the benefits of electrotactile feedback that were seen in prostheses (e.g., improved grasping), and indicate that similar advantages can be seen in VR for computerand/or machine-human interactions.…”

<div>Haptic feedback is critical in a broad range of human-machine/computer-interaction applications. However, the high cost and low portability/wearability of haptic devices remains an unresolved issue, severely limiting the adoption of this otherwise promising technology. Electrotactile interfaces have the advantage of being more portable and wearable due to its reduced actuators’ size, as well as benefiting from lower power consumption and manufacturing cost. The usages of electrotactile feedback have been explored in human-computer interaction and human machine-interaction for facilitating hand-based interactions in applications such as prosthetics, virtual reality, robotic teleoperation, surface haptics, portable devices, and rehabilitation. This paper presents a systematic review and meta-analysis of electrotactile feedback systems for hand based interactions in the last decade. We categorize the different electrotactile systems according to their type of stimulation and implementation/application. We also present and discuss a quantitative congregation of the findings, so as to offer a high-level overview into the state-of-art and suggest future directions. Electrotactile feedback was successful in rendering and/or augmenting most tactile sensations, eliciting perceptual processes, and improving performance in many scenarios, especially in those where the wearability/portability of the system is important. However, knowledge gaps, technical drawbacks, and methodological limitations were detected, which should be addressed in future studies.</div>

“…In these approaches, the feedback is determined by the tactile interaction, but cannot readily be designed to programmed to depend on the surface being touched or the state of a digital application. Other approaches to haptic virtual reality have used electronic gloves or exoskeletons [15], [16], [17], finger mounted haptic devices [18], [19], [20], [21], [22], or grasped controls [23]. Such systems have rarely integrated feedback from both real and virtual objects during free-hand interactions.…”
