Vaegan Seminar: Role of virtual reality and augmented reality in the field of low vision rehabilitation

Abstract: There is limited literature assessing the usability of virtual reality (VR) and augmented reality (AR) in the field of low vision rehabilitation. This lecture focuses on the use of VR and AR technologies in visual rehabilitation. Focus-group discussions involving people with central field loss and peripheral field loss were organized based on 3D virtual scenarios that were designed, developed and validated on people who were normally sighted.  A composite score was created to understand the visual performance while performing real-life activities.  An AR head mounted display was also used to test the visual functions of people with low vision. Participants were grouped into three categories: central field loss, peripheral field loss and overall blurred vision. The usability and perceptual experience of this AR device was studied while performing daily living activities.
