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
