US Patent 10528138 Virtual reality garment capable of jamming user movement

A virtual reality system including a garment worn by a user, such as a glove, includes a jamming that jams movement of a portion of the user's body by increasing a rigidity of certain portions of the garment or by preventing a certain portion of the garment from expanding past a certain length. This allows the garment to simulate the physical sensation that occurs when the user touches an object. For example, to simulate the sensation of holding a coffee mug, the jamming mechanism prevents the user's fingers from curling after the user's fingers have reached a position equivalent to making physical contact with the coffee mug.
