A system for transmitting signals between a body of a living being and a virtual reality space includes a wearable device configured to be worn on the body. The device provides haptic feedback to the body indicative of interactions between a virtual body and one or more virtual objects within the virtual reality space. The device includes a base affixed to the body, a container supported on the base, and a flow control device that controls flow of a mass between the container and a tank. A controller generates a flow control signal to control the flow control device responsive to an interaction between the virtual body and a virtual object within the virtual reality space. The container assumes an expanded state in which the container assumes a defined shape when the mass is present in the container and a contracted state in the absence of the mass.
