Abstract

Virtual Environments (VEs) are a common occurrence for many computer users. Considering their spreading usage and speedy development it is ever more important to develop methods that capture and measure key aspects of a VE, like presence. One of the main problems with measuring the level of presence in VEs is that the users may not be consciously aware of its affect. This is a problem especially for direct measures that rely on questionnaires and only measure the perceived level of presence explicitly. In this paper we develop and validate an indirect measure for the implicit level of presence of users, based on the physical reaction of users to events in the VE. The addition of an implicit measure will enable us to evaluate and compare VEs more effectively, especially with regard to their main function as immersive environments. Our approach is practical, cost-effective and delivers reliable results.
