ECSE student used machine learning to improve navigation of people with low vision

Associate Professor Vineetha Kalavally and Choong Wee Heng

ECSE graduate, Choong Wee Heng, co-authored a paper with Associate Professor Vineetha Kalavally, where they showed that the contrast between the background and foreground colors in an indoor space can be enhanced through lights which are trained using machine learning. The algorithm searches for the optimal light spectrum based on the reflectance spectra of the two colors and was found to improve the mobility of subjects wearing low vision simulation glasses in a real-world experiment. The paper, which is partly based on Choong Wee’s final year project, was published in the Q1 journal, Buildings and Environment in 2019.
