Haptic feedback widely means tactile feedback or force feedback. That kind of devices are called haptic devices. A haptic glove can generate forces to user''s fingers to feel a virtual object.In this paper, a wearable haptic glove system is introduced which was designed for virtual environments. Many conventional haptic devices have electrical motors and bulky exoskeleton so they have large volume and heavy weight. It is not easy to move with haptic devices.In order to reduce the weight of the system, McKibben type micro artificial muscle was used and micro hydraulic system was developed for actuating micro artificial muscles. And we developed a small pressure sensor which needs little water flux, so it optimized this system. For sensing a user''s finger angle, slim Flex sensors are used. And we designed a 3-finger slim haptic glove frame for small size and efficient force transmission from artificial muscles to user''s fingers. A controller consists of industrial PC, multifunctional I/O board and motor driver. We realize force control of McKibben artificial muscles, which is based on the force generating function of the McKibben artificial muscle.Finally, we connect haptic glove with virtual environments for verifying functionality and usability. Also we compare the slim haptic glove with conventional haptic gloves.
