UnlimitedHand is an VR gaming controller as developer kit. It not only reads hand’s gesture, but also controls fingers and hand by EMS(Electronic Muscle Stimulation). This technology enable us to touch and feel a pseudo-object in the virtual world.

Technical Overview

Input-Reading hand’s motions and gesture, put them into the virtual world.


A motion sensor and an array of muscle movement sensors*1 are embedded into the UnlimitedHand. These components allow the wearer to input Hand and Finger movements into virtual environments.

Output – UnlimitedHand sends EMS to our arm and controls fingers and hand.

a multi-channel Electric Muscle Stimulation device*2 is built in to the device. This component contracts the muscles on the wearer’s forearm to simulate haptic feedback.


*1 Array of muscle movement sensors:
A technology that monitors the positioning of muscles on the forearm to deduce finger movements.
*2 Electric Muscle Stimulation device:
A technology that passes electrical stimulus through tissue and muscles on arms or legs to generate movement.
