ABSTRACT
For non-sport fans, perceiving the excitement of surrounding fan groups and the arousal of collective emotions are some of the crucial factors that motivate their engaged excitement and loyalty in a sport;these factors are closely related to the process of evolution from a non-fan to a fan. The global COVID-19 pandemic changed the way of sport-watching from watching at the arena to watching from home alone. This has highlighted significant difficulties in the excitement transmission and arousal channel between non-sport fans and fans. Previous remote emotional intervening mediums had been limited to the use of virtual avatars to convey partners' external cues (such as appearance), to enhance the sense of presence from visual-audio perspectives. In this study, we explored a novel remote emotional intervening medium that conveys sport-fans' internal cues (bio-signals) that are widely believed to be related to internal emotional states of human, and displays those signals in a way that gives non-sport fans a deeper and more immersive experience: haptic feedback experience. Three bio-signal-based haptic feedback prototypes were developed, including heart-rate-based vibration, electromyography (EMG)-based pressure, and skin-temperature-based thermal feedbacks. An exploratory pilot study was conducted on a group of non-sport fans in a lab-control environment of remote-sport-watching to explore the effectiveness of the proposed mediums in enhancing their perception of sport-fan's excitement (emotion perception). Besides, we also analyzed non-sport fans' heart rate data when they were participants in the experiments to measure the performance of the proposed mediums in evoking the engaged excitement of non-sport fans (emotion arousal). Our results indicate the outstanding ability of EMG-based pressure feedback in effectively enhancing the process of emotion perception and the notable advantage of heart-rate-based vibration feedback in the arousal of non-sport fans' engaged excitement. This study presents the potential utility of bio-signal-based haptic feedback in augmenting remote emotional perception and arousal and also provides the underlining support for the future exploration and development directions for social computing based on bio-signals and haptic technologies. © 2022 ACM.
ABSTRACT
Regular physical exercise is essential for overall health; however, it is also crucial to mitigate the probability of injuries due to incorrect exercise executions. Existing health or fitness applications often neglect accurate full-body motion recognition and focus on a single body part. Furthermore, they often detect only specific errors or provide feedback first after the execution. This lack raises the necessity for the automated detection of full-body execution errors in real-time to assist users in correcting motor skills. To address this challenge, we propose a method for movement assessment using a full-body haptic motion capture suit. We train probabilistic movement models using the data of 10 inertial sensors to detect exercise execution errors. Additionally, we provide haptic feedback, employing transcutaneous electrical nerve stimulation immediately, as soon as an error occurs, to correct the movements. The results based on a dataset collected from 15 subjects show that our approach can detect severe movement execution errors directly during the workout and provide haptic feedback at respective body locations. These results suggest that a haptic full-body motion capture suit, such as the Teslasuit, is promising for movement assessment and can give appropriate haptic feedback to the users so that they can improve their movements.

Telesurgery, or remote surgery, is widely known as a master-slave technology. It has achieved a milestone in surgical technology and intervention, providing widespread prospects of operating on a patient in a remote area with increased accuracy and precision. It consists of one or more arms controlled by a surgeon and a master controller in a remote area accessing all the information being transferred via a telecommunication system. This paper reviews the present advancements and their benefits and limitations in the field of telesurgery. A handful of operations have been done so far. However, due to time-lag (latency), global networking problems, legal issues and skepticism, and on top of the cost of robotic systems and their affordability have led to the concept of telerobotics and surgery to lag. However, with more information and high speed, 5G networking, which has been in a trial to reduce latency to its minimum, is beneficial. Haptic feedback technology in telesurgery and robotics is another achievement that can be improved; further, this allows the robotic arms to mimic the natural hand movements of the surgeon in the control center so that the master controller can perform surgeries with more dexterity and acuity. Due to coronavirus (COVID-19), this type of surgery approach can reduce the probability of contracting the virus, saving more lives and the future.
