碩士 === 中華科技大學 === 電子工程研究所碩士班 === 104 === The design in this paper is based on the MEMS chip, coupled with Bluetooth wireless transmission to construct a wearable inertial navigation device. The technical realization of Unity game engine control is based on the game script of a virtual reality treasure hunt, with Ancient China as the background. The wearable device proposed in this study uses the ATMega 168 chip as the main core controller. In addition, with a three-axis accelerometer and gyro sensor combined, the player’s forward, backward, and turning motions can be detected, which are transmitted to the Unity 3D game engine through Bluetooth to achieve the first-person character control game software. In order to achieve the realistic effects of the game themes, this study applied 3ds Max modeling software to produce various object models, including: Ancient Chinese architecture (huts), ancient Chinese pavilions, etc., which were imported into the Unity3D software to design a virtual world with Ancient China as the background, thus allowing players to enter the virtual world, where virtual characters engaged in a treasure hunt can be controlled in an interactive somatosensory fashion. This will allow players to feel as if they are personally on the science. Unity 3D is a professional cross-platform game development software with powerful virtual reality, VR functions. Game scripts are written with the combined use of C# or Java language. The cross-platform software can be operated on different platforms, including Windows, Mac OS, and Linux. Over the past, game players could only control objects established in game scripts through a keyboard and mouse. This paper emphasizes the inertial sensor components of the wearable device that can detect physical movements, allowing players to immerse in the virtual reality, VR world and timely interact with game scripts, making them feel as if they are personally on the scene. This paper combines interactive elements between reality and vitality, which gives players a whole new experience of games, driving simulations, medical surgeries, and even business conducts of various sorts. The experimental results show that the wearable device proposed in this study possesses functional stability. It is with much anticipation that more innovative applications be elicited to change people’s lifestyle once and for all.
