Employing virtual reality technology for risk assessment – the implications of the subjective experience

The project investigates factors influencing risk assessments of machine prototypes when using virtual reality technology. The project is concerned with two aspects: how should virtual models be designed to be effective when conducting risk assessment of prototypes and whether virtual reality technology is an effective method for safety instruction.

In collaboration with psychology and mechanical engineering, two experiments were carried out. In Experiment 1, the risk assessments of different types of virtual machine models carried out by safety experts was compared with a reference risk assessment of the real prototypes. The results showed that virtual models that are schematic achieve similar risk assessments as highly complex animated models when compared to the real prototype.

In Experiment 2, a study was carried out to determine if novice can be better prepared for working with high risk machined when using virtual animated machine models than traditional methods of teaching by means of presentations and videos. The study showed that the use of virtual reality technology leads to a greater change in risk assessment than the traditional approach.
