About

Paul W. Marshall is a pioneering researcher in human-computer interaction, with a focused expertise in sensory substitution systems and rapid prototyping methodologies. His most influential work centers on the development of low-fidelity tactile interfaces that enable novel forms of perception, most notably through his foundational 2009 paper on "Low-Fi Skin Vision." In this landmark study, Marshall demonstrated how a minimal system of just twenty vibration motors could allow blindfolded subjects to successfully track and bat a rolling ball, effectively experiencing a form of "skin vision." This work, which has garnered 9 citations, represents a significant contribution to assistive technology and embodied interaction, showing that complex sensory substitution does not require expensive, high-fidelity hardware. Marshall's approach—prioritizing rapid prototyping and iterative design—has influenced how researchers develop accessible, low-cost sensory aids. His research sits at the intersection of tactile perception, wearable computing, and inclusive design, challenging assumptions about the minimum requirements for meaningful sensory substitution. Through this work, Marshall has helped establish a more pragmatic, user-centered path for creating technologies that augment human sensory capabilities.
