What is a sense? There are tactile sensations, auditory sensations, tactile sensations, olfactory sensations, and taste sensations called the five sensations, as well as visceral sensations, equilibrium sensations, and cutaneous sensations called the outer brain. The sensation generated by the RiMM device reproduces the tactile pressure and pain sensation of the tactile glove, and the balance and skin sensation of the low-floor sway device.
How do you feel scared? Unfamiliar calamities are afraid. More effective sensations of fear are tactile pressure, pain, skin, and balance.
It is the case where an object is approaching that you can visually recognize the fear. This phenomenon is associated with experience and replaces scary. Experiments have shown that adults react and take action to escape when they show an image of a stone approaching, but inexperienced infants avoid it and keep their posture as it is. (This is the answer I got from university pedagogy and VR experiments.) Therefore, you can see how important tactile sensation is by feelings other than vision.
