Abstract. This paper presents a platform, named Cybertouch, for 3D Virtual Reality Head-Mounted Display (VR HMD) providing both touch and cursor interface using wearable IMU devices to enable real-time selection of operational commands together with recognition of user motions and gestures. One of the constraints of the conventional 3D HMD widely used in VR games or training systems is blocking of user's visual perception while wearing an HMD. Because the environment and input devices are invisible during the operation, there may be a limitation in an application caused by restriction of user input commands. Proposed Cybertouch provides a User Interface which is a kind of combined functions of traditional mice and touch panel devices, specialized in games or immersive virtual training applications using 3D HMD.
