“…In Lopes et al [25], the user pushed a virtual object and, when the object "hit" a wall in the physical environment, the user felt a bumping sensation on their shoulders and wrists. Additionally, Ishimaru et al [35] focused on creating the sensation of bumps during virtual interactions. They demonstrated that electrical stimulation is superior to mechanical vibration for simulating large bumps and uneven surfaces, providing a more realistic haptic experience.…”

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.

“…On the other hand, the stimulus above the tendon might eventually become a muscle stimulus and cause a weak muscle contraction, affecting the Golgi tendon organ and muscle spindles and producing force sensation. However, according to the conventional EMS work [5][6][7][8][9][10][11] that stimulated the same muscle to mimic an external force, they produced a force sensation opposite to the one produced by stimulating the tendon organ. In order to investigate whether our proposing method is based on muscle stimulation or not, we placed electrodes not only on the tendon but also on the muscle belly of the biceps muscle (Figure 1a) as a condition that actively induces muscle contraction.…”

“…Our hypothesis is as follows. Stimulation of the tendon will increase force sensation, while stimulation of the muscle belly will decrease it because the stimulation will act as a force driving in the direction of elbow flexion (in the opposite direction to the force due to the weight) as in the conventional method [5][6][7][8][9][10][11].…”

“…Indeed, some studies showed that one actuator could cover a multi-dimensional haptic feedback motor system [3,4]; however, the situation where the technique is available is limited, and a heavy motor is still required for a large degree of torque. On the other hand, a method to present force by controlling human muscles with electrical stimulation (EMS) has been proposed [5][6][7][8][9][10][11]. This method requires only a tiny electrical circuit board for power supply, one for stimulus control, and electrodes to be placed on the human body, the net size of all of which is much smaller than the devices using electromagnetic motors.…”

Many wearable interfaces have been proposed to present force to the upper limb and elbow joint. One way to achieve a compact wearable haptic interface is to use electrical stimulation, and we have suggested that transcutaneous electrical stimulation above the wrist tendon can produce force a sensation in the direction of the muscle stretching; however, it has not been investigated in detail whether the force sensation presented by the electrical stimulation of the tendon occurs in the upper limb joints. In this study, to investigate whether the force sensation is generated when applying electrical stimulation of the skin at the tendon or at the muscle belly of the biceps brachii muscle, we quantitatively evaluated the direction and amount of the force sensation under the aforementioned conditions. The results showed that the electrical stimulation of the tendon produced significant force sensation in the direction of elbow extension. On the other hand, in some participants, the electrical stimulation of the muscle belly worked as a supporting force, resulting in the sensation of weakened force perception. In general, we concluded that the sensation produced by muscle stimulation was different from that produced by stimulation of the tendon.

“…After that, we presented the sensation of bumps using EMS to the participants and verified the effectiveness by comparing it with the existing method. Part of this paper was published at the Haptics Symposium 2020 [ 24 ] and the IEEE/SICE International Symposium on System Integration 2022 [ 25 ].…”

Currently, visual Augmented Reality (AR) technology is widespread among the public. Similarly, haptic AR technology is also widely practiced in the academic field. However, conventional haptic AR devices are not suitable for interacting with real objects. These devices are often held by the users, and they contact the real object via the devices. Thus, they prevent direct contact between the user and real objects. To solve this problem, we proposed employing Electrical Muscle Stimulation (EMS) technology. EMS technology does not interfere with the interaction between the user and the real object, and the user can wear the device. First, we examined proper stimulus waveforms for EMS, in addition to pulse waveforms. At the same time, we examined the appropriate frequency and pulse width. The waveforms that we used this time were a sawtooth wave, a reverse sawtooth wave, and a sine wave. Second, to clarify the characteristic of the force presented by the EMS, we measured the relationship between the input voltage and the force presented and obtained the point of subjective equality using the constant method. Subsequently, we presented the bump sensation using EMS to the participants and verified its effectiveness by comparing it with the existing methods.
