Visual Processing Speed

The goal of this clinical trial is to evaluate the effectiveness of an immersive virtual-reality (IVR) based stimulation program, in improving visual perception for people who have lost their driver's license due to perceptual or cognitive impairments. The main questions it aims to answer are: 1. Can the 6-week IVR stimulation program help improve driving performance? 2. Will participants experience improvement in visual detection and perception after training? Study Design Summary: * Participants will be randomized into a waitlist group or intervention-first group * The VR-based intervention will consist of training every 2 days for six weeks * Waitlist group will wait 6 weeks before starting intervention at study midpoint (week 7) * Intervention-first group will begin with intervention (week 1-6) and then stop intervention at study midpoint * Participants will complete tests related to driving performance, visual attention, and visual fields at the start of study, midpoint, and end of study Researchers will analyze data for changes from baseline in outcome measures.
