About the Seminar

The consideration of vision loss is of growing importance in research, planning, and implementation of travel and transportation needs. There are approximately 12 million people with some form of visual impairment in the United States, and this number is estimated to double in the next 20 years as a consequence of our aging population. To meet the needs of this growing population, far more research is needed to better understand what information is used to support spatial behaviors for people with low (or no) vision.

In this seminar, Nicholas Giudice discussed some practical solutions that can improve information access, safety, and efficient travel for people with vision loss. He also explained why the failure to consider human perceptual and cognitive factors often leads to poor design decisions—especially when incorporating auditory, haptic, and other non-visual information into traditional navigation systems and transportation networks.


Nicholas Giudice is an assistant professor in the Department of Spatial Information Science and Engineering at the University of Maine and the director of the Virtual Environment and Multimodal Interaction Laboratory. His research integrates expertise in perception, cognitive neuroscience, and human factors engineering.
