Ricerche in Ergonomia
Falls from scaffolds are one of the most frequent causes of fatal or serious injuries in building and construction setting. To prevent such injuries, the availability of effective education and training methods and tools is of paramount importance. The one-year long EU (SAFE) project Vecwit (Virtual Environment for Construction Workers Training and Instruction) has been conceived to set up a virtual reality (VR) environment that shall serve as an educational tool for construction workers' education and training. Specifically, the project had two main goals: to improve trainees' risk perception and expertise on safe behaviors while working on scaffolds. The project foresaw four different steps. First, a preliminary definition of the technological platform was made. Second, task analysis was performed to get a model of the more risk situations and define the scenarios to be implemented. Third, a VR prototype with the system's main features was developed. Finally, an ergonomic study was designed to evaluate both system's usability and training effectiveness. The study involved two groups of eight young workers (novices and already experienced ones) who had to perform the following tasks:
The ergonomic study resulted in a number of findings related to educational effectiveness and specific usability problems related to VR systems.
