Impact of Immersive and Interactive Information Visualization on OccupantÕs Lighting Choices

Abstract: Feedback systems often use Information Visualization (InfoVis) to inform occupants about the impact of their choices on energy consumption, aiming at reducing occupant behaviour related waste in buildings. In this pilot study, we use InfoVis as a tool to influence occupantsÕ opinions about a roomÕs lighting quality instead of their energy consumption. Lighting significantly affects occupantsÕ mood, productivity, and wellbeing. We utilize InfoVis to present the light quality data throughout a day via an animated daylight cycle, as well as light levels and light distributions through static and animated heat maps to enable occupants to make more informed decisions related to lighting. InfoVis is presented within the spatial context by overlaying visualizations on the room itself, on its floor and the desk surface, using an immersive virtual environment. The results show that the participants changed their choices once provided with more information related to the quality and amount of lighting in the room. Specifically, the participants changed their choices significantly more when the illuminance levels and distribution over time (dynamic heat maps) were presented. The findings of this research can inform the development of better visualization techniques that could increase occupant awareness about environmental conditions in buildings.
