The Vehicle Pattern for Simplifying Cross-Platform Virtual Reality Development

Maintaining an application across different virtual reality systems can be difficult and time-consuming. Different systems require different strategies for implementing simple interactions such as locomotion and object manipulation. In this chapter, we describe a pattern that we have used to minimize the interactions between the interaction style (behaviour) with the scene elements, and the specific interaction devices. The vehicle pattern allows the programmer to ignore most of the implementation details of hardware and interaction, and focus on the scene description. They can then easily generate versions of the scene for different systems. We demonstrate the principles of the vehicle pattern with an outline implementation in Unit

A Way to a Universal VR Accessibility Toolkit

Virtual Reality (VR) has become more and more popular with dropping prices for systems and a growing number of users. However, the issue of accessibility in VR has been hardly addressed so far and no uniform approach or standard exists at this time. In this position paper, we propose a customisable toolkit implemented at the system-level and discuss the potential benefits of this approach and challenges that will need to be overcome for a successful implementation
