Japanese and French engineers have found that the vibration in the hands causesusers to think that they are
Previously, it was found that if you move an objectfaster than the hand moves, a person perceives it as very light, and if vice versa, then it will seem heavier. However, this effect is rather weak. The engineers tried to find a way to strengthen it.
They suggested using vibration in the hands.Specialists have created straps with two vibration motors. They vibrated at a frequency of 80 hertz. The action of the straps was tested on 20 volunteers. First, the vibration was turned on for six seconds and the subjects were asked if the illusion of movement arose. Based on the responses, calibration was carried out. As a result, the vibration helped reinforce the illusion of variable weight.
