“…Fast-Tracking EMS Prototyping via Toolkits and Advanced Wearables: Building applications for EMS is a multifaceted task, demanding in-depth expertise in hardware, software, and understanding of physiological features. Recognizing this complexity, the "Let Your Body Move" toolkit has been developed by [42] to streamline EMS prototyping. This comprehensive toolkit offers a Bluetooth-equipped hardware control module that uses standard EMS devices for signal generation.…”

This paper presents a thorough review of electrical muscle stimulation (EMS) in the context of augmented reality (AR) and virtual reality (VR), specifically focusing on its application in providing kinesthetic feedback. Our systematic review of 17 studies reveals the growing interest and potential of EMS in this domain, as evidenced by the growing body of literature and citations. The key elements presented in our review encompass a catalog of the applications developed to date, the specifics of the stimulation parameters used, the participant demographics of the studies, and the types of measures used in these research efforts. We discovered that EMS offers a versatile range of applications in AR/VR, from simulating physical interactions like touching virtual walls or objects to replicating the sensation of weight and impact. Notably, EMS has shown effectiveness in areas such as object handling and musical rhythm learning, indicating its broader potential beyond conventional haptic feedback mechanisms. However, our review also highlights major challenges in the research, such as inconsistent reporting of EMS parameters and a lack of diversity in study participants. These issues underscore the need for improved reporting standards and more inclusive research approaches to ensure wider applicability and reproducibility of results.

Fitness is one of the popular physical activities performed individually most of the time. While doing an activity, if the proper posture is not adopted, it can result in major injury that makes it difficult to lead a healthy life. By adopting wearable technology and haptic technology not only correct motion could be achieved but also damages due to wrong motion could be prevented. In this article we introduce a simple and convenient wearable device that can sense the position of the body during the exercise and provide haptic feedback if an improper motion was performed. The wearable system includes four gyroscopes and four coin types of vibration motors. The body position was recorded using gyroscopes and haptic feedback was applied using vibration motors. To test the system three positions were chosen and tested on five participants. The results show that the device can be used by people to have an injury-free activity where a coach is not available. Using wearable technology accompanied by the haptic feedback will improve the skills and will lead to an injury free exercise.

“…However, conventional haptic devices such as grounded type device, e.g., Phantom [ 18 ] and Omega [ 19 ], and exoskeleton type devices has limitations to be used in general VR applications due to the restricted workspace, complex and heavy mechanical components [ 15 , 20 , 21 ]. The haptic devices using electrical muscle stimulation (EMS) can be a feasible alternative to the conventional haptic devices by virtue of its light and flexible feature enabling the development of wearable haptic devices in the form of arm bands [ 14 , 16 , 22 , 23 , 24 ] and haptic suit [ 17 ]. EMS produces a synthetic haptic sensation by inducing muscle contractions using electrical stimulations delivered through electrodes attached to the skin surfaces [ 25 ].…”

“…The same stimulation may be experienced differently by different people. Most previous studies on EMS-based haptic rendering have used pre-determined stimulus patterns [ 14 , 16 , 23 , 24 ]. In these methods, the deliverable haptic sensation was limited to simple interactions such as recognizing certain boundaries and existence of virtual objects, and a precise haptic sensation could not be transmitted.…”

A haptic interface based on electrical muscle stimulation (EMS) has huge potential in terms of usability and applicability compared with conventional haptic interfaces. This study analyzed the force response characteristics of forearm extensor muscles for EMS-based haptic rendering. We introduced a simplified mathematical model of the force response, which has been developed in the field of rehabilitation, and experimentally validated its feasibility for haptic applications. Two important features of the force response, namely the peak force and response time, with respect to the frequency and amplitude of the electrical stimulation were identified by investigating the experimental force response of the forearm extensor muscles. An exponential function was proposed to estimate the peak force with respect to the frequency and amplitude, and it was verified by comparing with the measured peak force. The response time characteristics were also examined with respect to the frequency and amplitude. A frequency-dependent tendency, i.e., an increase in response time with increasing frequency, was observed, whereas there was no correlation with the amplitude. The analysis of the force response characteristics with the application of the proposed force response model may help enhance the fidelity of EMS-based haptic rendering.
