Abstract
Virtual training systems are in an increasing demand because of real-world training, which requires a high cost or accompanying risk, and can be conducted safely through virtual environments. For virtual training to be effective for users, it is important to provide realistic training situations; however, virtual reality (VR) content using VR controllers for experiential learning differ significantly from real content in terms of tangible interactions. In this paper, we propose a method for enhancing the presence and immersion during virtual training by applying various sensors to tangible virtual training as a way to track the movement of real tools used during training and virtualizing the entire body of the actual user for transfer to a virtual environment. The proposed training system connects virtual and real-world spaces through an actual object (e.g., an automobile) to provide the feeling of actual touch during virtual training. Furthermore, the system measures the posture of the tools (steam gun and mop) and the degree of touch and applies them during training (e.g., a steam car wash.) User-testing is conducted to validate the increase in the effectiveness of virtual job training.
Highlights
In job training, it is extremely important to provide job trainees with the opportunity to have a realistic experience within an unfamiliar work environment
We propose a virtual reality (VR)-based job training system, in which users use real tools to provide tangible virtual training service
We developed a virtual training system using real objects to improve the tangible interaction during virtual environment-based training
Summary
It is extremely important to provide job trainees with the opportunity to have a realistic experience within an unfamiliar work environment. In mixed reality (MR) systems, physical objects can be controlled in a simple way such as translation and rotation and do not provide physical senses of touching This method facilitates only simple experiences in fields where training requires real contact (training using tools) rather than simple selections, and it is difficult to use at a level of actual applied force in training. The proposed system provides a steam car wash training program to job trainees for safe, repeatable, and practical training This system uses a method of matching the vehicle model in a virtual environment with the coordinate system of the vehicle body in the real environment allowing the users to be trained while feeling an actual contact sensation when wiping with a mop in the virtual environment.
