Byeongjin Kim, a Ph.D. candidate of Color Lab, had a presentation titled ‘Context-Aware Lighting for Office Lounge: Algorithm Proposal and User Study’ at the Korean Institute of Illuminating and Electrical Installation Engineers Autumn Conference 2023. He researched to build a smart lighting system that adjusts the illumination based on the context occurring in the office lounge. The lighting solutions were carried out through the expert interview. The system was installed in two offices for a week and has been verified for usability. The effectiveness of the proposed system was recognized with the Best Presentation Award at the conference.

Abstract

This study proposes a context-aware lighting preset for the office lounge based on user behavior. We explored five kinds of optimal light scenarios: empty, relaxation, discussion, chatting, and party while matching them with patterns of user behaviors. First, we designed lighting solutions for each context through expert interviews. Using these, we developed an algorithm that detects the number of users, their movement, and their sound volume using a camera and microphone. Furthermore, we discussed the challenges for better implementation.
