DR. JR Rizzo: Super Powers for the Blind, Part 2

RUSK Insights on Rehabilitation Medicine

Dr. Rizzo currently serves as director of innovation and technology in the department of rehabilitation medicine. He has published extensively. His research topics include: biomechanics; assistive and wearable technology; blindness and visual impairment; and sensory augmentation. He is a graduate of New York Medical College and completed his residency in physical medicine and rehabilitation at NYU as well as a clinical research fellowship at the Rusk Rehabilitation Institute.

Dr. Rizzo began Part 2 of his grand round presentations with the question, “OK, what were our findings?” With existing GPS data sets, we need to be mindful of side view versus front view in where cameras are positioned. A data set being described had more side view images than front view, which can be extremely important for the visually impaired. He pointed to being excited about a collaboration with the United Nations. We have shared these data with that organization and they are quite impressed with our results, which can be of potential use to blind individuals navigating the UN building. We are creating a cellphone application that uses vision in place recognition. The UN is providing some funding support for a master’s student working on this project. Dr. Rizzothen responded to a question regarding falls and whether there is information to assess the relative slipperiness of surfaces. Ground surfaces are attracting more attention, such as puddles and how to reroute pedestrians around hazardous terrain. He then described a reconstruction project that is underway to change different environments by developing new approaches to navigating subway stations consisting of multiple floors and tracks. He played a video clip that shows how reconstruction is occurring. He addressed the question of how we handle all this video data for these mobility platforms and what a technician must do with all this high-resolution video data arriving. He also indicated that we currently are looking at sending the data and having new transmission policies, and also work being accomplished on dual connectivity. A question-and-answer period followed his presentation.
