Human Centric Lighting-based Machine Learning Systems for Adult Healthcare in Intelligent Buildings

Project Description


The aim of this project is the development of a novel machine learning-based optical IPS system for adult healthcare in intelligent buildings. The proposed digital embedded system should be low cost and incorporate bespoke optical elements as secondary optics for increased position accuracy.

The topic of energy efficiency is gaining in importance globally due to ecological and economic reasons. One of the trends to reduce electricity bills and CO2 emissions is the replacement of non-efficient sources of illumination with energy efficient ones. Light Emitting Diodes (LEDs) in particular are becoming pervasive not only because of their reduced energy consumption, low cost and long life spans, but also because they can be used to transmit data. Furthermore machine intelligence (machine learning) is further optimising energy efficiency within electronic systems.

One of the technologies in which LEDs have great potential as both data transmission sources and lighting devices is indoor positioning systems (IPS), which can be used in a wide variety of applications. Optical IPS have great potential, for instance, in the field of health where they can be used to track equipment and/or patients in hospitals and care homes. This is particularly relevant in aging societies where an increasing number of people are developing conditions related to dementia.


Machine learning techniques can allow improved accuracy within application domains. However, a common issue with machine learning involves significantly high implementation computational processing requirements. This significant level of computational requirements can be reduced to improve power consumption with designing specific hardware architecture within the specific, unique and problematic infrastructure of IPS applications.
The proposed project aims to improve accuracy in low cost optical IPS systems by combining novel free-form lenses with LEDs within luminaires. The improved accuracy will explore machine learning to achieve low power implementation on novel embedded digital system architecture.
