Abstract

Background: Virtual environments in medical education are becoming increasingly popular as a learning tool. However, there is a large amount of evidence linking these systems to adverse effects that mimic motion sickness. It is also proposed that the efficacy of such systems is affected by how well they engage the user, which is often referred to as presence.

Purpose: This primary purpose of this study was to look at the side effects experienced and presence in the Virtual Environment for Radiotherapy Training (VERT) system which has recently been introduced.

Method: A pre-VERT questionnaire was given to 84 subjects to ascertain general health of the subjects. The simulator sickness questionnaire was utilised to determine the side effects experienced, whereas the igroup presence questionnaire was used to measure presence. Both questionnaires were given immediately after use of the VERT system.

Results: The majority of symptoms were minor; the two most commonly reported symptoms relating to ocular issues. No relationship was seen between simulator sickness and presence although subjects with a higher susceptibility to travel sickness had reported higher levels of disorientation and nausea. There was also a decrease in involvement with the system in subjects with a higher susceptibility to travel sickness.
