“…In our previous report [13], we preliminarily confirmed that multi-point vibratory stimulation induced more steady illusion than the illusion induced by one or two points of stimulation. In this paper, we investigate the effects of multi-point vibration in more detail as well as the contribution of each vibration position to the illusion.…”

“…We presented vibration stimulation to seven positions on the left chest, upper arm, and forearm to induce the arm extension illusion, and Fig. 1 (left) shows the vibrator positions (1 to 7) over the same tendons that we tested in our previous report [13]. We hypothesized that each vibratory stimulation would contribute differently to the illusion and illusions induced by each vibration could be composited linearly as the vector model of the illusion [9,11].…”

Kinesthetic sensation is important for improving presence and immersion in VR environments. However, presenting kinesthetic sensation usually requires a large space so as to avoid users colliding with objects or other users. One of the ways to tackle this issue is to use kinesthetic illusion, which is a way of presenting kinesthetic sensation without physical motion. However, realizing dynamic motion and fast movement remains difficult. Considering that multiple synergist muscles are usually involved in a movement such as walking or even simple arm movement, stimulating multiple synergist muscles might enhance the illusion. Thus, we investigated whether multi-point vibratory stimulation to multiple synergist muscles enhances induced kinesthetic illusions. We found that stimulating multiple synergist muscles created more vivid illusions. Additionally, we found that our method was effective for inducing steady illusions. We also calculated the contribution of each proposed stimulation point to the illusion.
