About

Paul Marshall is a leading researcher in Human-Computer Interaction (HCI), whose work explores the profound intersection of embodied interaction, tangible computing, and sensory substitution. His research fundamentally investigates how our physical bodies shape our experiences with technology, with a particular focus on designing novel interfaces for diverse users. Marshall’s major contribution includes pioneering work on rapid prototyping for sensory substitution systems, most notably the "Low-fi skin vision" project (2009, 22 citations), which demonstrated how a minimal, 20-motor tactile vest could enable blindfolded users to successfully track and bat a rolling ball—effectively creating a form of "skin vision." This work showcases his commitment to low-cost, accessible assistive technologies. He has also been instrumental in shaping the theoretical foundations of embodied interaction, particularly for children, as seen in his influential 2009 paper (7 citations) that established a framework for understanding how children's physical interactions with computation differ from adults'. Marshall’s work is notable for its elegant blend of rigorous prototyping, theoretical depth, and a human-centered focus on inclusion and accessibility, making him a key figure in the evolution of tangible and embodied HCI.
