Colour appearance in virtual reality: a comparison between a full-scale room and a virtual reality simulation

The main goal of our project is to make VR applications usable for the planning of light and colour. To enable reliable simulations, we both need to develop better rendering methods and carefully study the appearance of light and colour in real rooms and in virtual environments. Assessments of real rooms are compared to simulations of the same rooms in immersive Virtual Reality (3D-cube). In this paper, we will present the outcome of a pilot study and discuss specific problems associated with the prospect of comparing reality to Virtual Reality. We will account for the experience of the room and go into details on the experience and perception of light. Indeed, the problems of getting enough light in the 3D-cube and of simulating the light situation of a real room affect colour appearance
