A wearable force feedback device enables us to dynamically interact with a virtual object while moving in a wide virtual space. We have developed a wearable force feedback device with a pneumatic artificial muscle and a magnetorheological (MR) brake. These mechanical elements show quick response by feed-forward control and have high power density. In this paper, we tackled on weight saving of the device, and measured basic property again. Afterward, we evaluated whether operators could perceive the difference when rendered different magnitudes of frictional force or elastic force. The operators were rendered one of the five levels of force, and replied which level this force was.
