学徒培训是世界各国政府技能政策的核心。应用先进的资讯及通讯科技，可提高建造业培训的质素，并有助吸引年青人进入这个传统上形象欠佳及创新缓慢的行业。本文报道了一种新型混合现实（MR）系统的开发，该系统专门针对建筑行业工人，即熟练手工工人的培训。从一般培训的角度来看，该制度旨在解决现有建造业培训的缺点，特别是缺乏使学员能够在现实和具有挑战性的现场条件下进行培训的解决方案，同时消除职业健康和安全风险。从技术角度来看，该系统目前将最先进的虚拟现实护目镜与一种新颖的具有成本效益的6自由度（DOF）头部姿态跟踪系统集成在一起，该系统支持学员在房间大小的空间中运动，以及一个游戏引擎，以有效地管理投影在VR护目镜上的虚拟三维环境视图的生成。实验结果验证了六自由度头部姿态跟踪系统的性能，这是本文研究的主要计算贡献。然后，初步结果揭示了它的价值，使学员能够在不同的环境中体验建筑工地的条件，特别是在高处。提供了有关将系统扩展到设想的完整MR系统的未来工作的详细信息，在该系统中，受训者将在沉浸在虚拟项目环境中时执行实际任务，例如砌砖。(C) 2015美国土木工程师学会。
Apprenticeship training is at the heart of government skills policy worldwide. Application of cutting-edge information and communication technologies (ICTs) can enhance the quality of construction training, and help in attracting youth to an industry that traditionally has a poor image and slow in uptaking innovation. This paper reports on the development of a novel mixed reality (MR) system uniquely targeted for the training of construction trade workers, i.e.,skilled manual workers. From a general training viewpoint, the system aims to address the shortcomings of existing construction trades training, in particular the lack of solutions for enabling trainees to train in realistic and challenging site conditions, while eliminating occupational health and safety risks. From a technical viewpoint, the system currently integrates state-of-the-art virtual reality goggles with a novel cost-effective 6-degree-of-freedom (DOF) head pose tracking system supporting the movement of trainees in room-size spaces, as well as a game engine to effectively manage the generation of the views of the virtual three-dimensional environment projected on the VR goggles. Experimental results demonstrate the performance of the 6-DOF head pose tracking system, which is the main computational contribution of the research reported in this paper. Then, preliminary results reveal its value to enable trainees to experience construction site conditions, particularly being at height, in different settings. Details are provided regarding future work to extend the system into the envisioned full MR system whereby a trainee would be performing an actual task, e.g.,bricklaying, while being immersed in a virtual project environment.
