Visualization for an augmented reality construction machinery simulator

This work presents a versatile real-time simulator for training workers in the operation of construction machinery. With the aim of reducing the accident rate in the construction sector, a realistic AR scene improves the user experience. Our work addresses two stages of the training process. First, the instructor designs the working environment and the exercises with a specifically developed Scene Editor tool. Then, these exercises are run by the simulator. The simulation setup consists of a real cabin placed on a motion platform in order to provide a realistic interaction with the system and a stereoscopic augmented reality system for visualization. Visualization has been implemented as a chroma-key-based mixed reality system. This paper describes the development of the Visualization subsystem of this simulator.
