Extended Reality for Smart Built Environments Design: Smart Lighting Design Testbed

TL;DR

This paper tackles the challenge of designing and evaluating smart lighting within Smart Built Environments (SBE) using Extended Reality (XR) to automatically generate design prototypes from space functionality. It proposes an XR-based SBE smart lighting design testbed that generates prototypes from room geometry and function, while supporting manual adjustments and incorporating predefined design patterns aligned with LightingGuideline. A Unity-based bedroom case study demonstrates automatic room scanning, geometry identification, and the presentation of five design scenarios with real-time renderings. The work provides a practical framework for rapid, occupant-centered lighting design in SBEs, enabling exploration of lighting strategies and their potential impacts on comfort and well-being.

Abstract

Smart Built Environment is an eco-system of `connected' and `smart' Internet of Things (IoT) devices that are embedded in a built environment. Smart lighting is an important category of smart IoT devices that has recently attracted research interest, particularly for residential areas. In this paper, we present an extended reality based smart lighting design testbed that can generate design prototypes based on the functionality of the physical environment. The emphasis is on designing a smart lighting system in a controlled residential environment, with some evaluation of well-being and comfort.
