A body-grounded kinesthetic haptic device for virtual reality
Kinesthetic haptic devices can make us feel that we are touching or holding objects that are not actually there by applying a force directly onto a user's body. As a corollary of Newton's third law, these devices are typically attached to the ground or else they would not be able to apply a net …
