Design and evaluation of an ambient display to support time management during meetings

An explorative research to investigate the opportunities of using light as a communication medium to provide peripheral information is presented. An innovative ambient display, using dynamic light patterns on the walls of the meeting room to support time management during meetings has been developed. Designed according to the principles of calm technology and information decoration, the system seeks for a balance between aesthetical and informational quality. Two prototypes were created and qualitative research methods are used to evaluate the concept and the efficacy of light in conveying information. The results confirm the value of our concept by showing an appreciation of the usefulness and a good level of comprehension of the users towards the system. The project led to insightful considerations on design guidelines and recommendations for further development of ambient displays to use light to convey abstract information in a subtle, unobtrusive way
