Abstract

Virtual reality (VR) has become a very popular technology in recent years, which used in the field of multimedia for various purposes. One of the applications that widely used for simulating physical presence in the real world is walk-through VR. In the walk-through VR system will generate simulation character or avatar for user which able to control movement, especially first person movement walk-through in VR with many input devices. In this paper, we present a human-computer interaction with the connection of Oculus Rift and Leap Motion new technological devices for VR. Oculus Rift is VR headset or head-mounted display devices that have a small display optic in front of each eye. Oculus Rift can track head movement and change view point follow it. Leap Motion is in-air controller that can track hand gesture of the user. The combination of them will make users feel like immerse to VR. Users can move avatar any way in VR by their hand interact through the system via these devices. We introduce a new interactive hand gesture system with palm normal for control steering develop by the game engine Unity3D applies synchronization of Oculus Rift and Leap Motion. Our design and development method will allow users to adjust moving speed follows the hand gesture and the range of the user's hand that make a smoothly moving with acceleration.
