Virtual augmented exercise gaming for older adults.

This paper details the design, development, and testing of virtual augmented exercise (VAE) gaming for older adults. Three versions of an underwater VAE environment were tested with a sample of 22 healthy adults aged 50 or over. Participants strongly preferred VAE to traditional physical exercise, and adherence rate was 100%.

The effects of direction and movement of attractors on users' behavior in virtual environments.

Despite fast technological developments in virtual reality (VR), methodologies and guidelines for evaluating the design of virtual environments (VEs) are lacking. The theory of perceptual opportunities (POs) has previously been proposed as a basis of such a design methodology. This paper presents an empirical study investigating the effect of representation of POs on users' behavior in VEs.
