Semaphore is a research cluster at the Faculty of Information, University of Toronto, dedicated to inclusive design in the area of mobile and pervasive computing. At the heart of this research are the complementary goals of providing (a) the ability to access mobile and pervasive computing services and information in a variety of settings, activities and environments and (b) the ability to transform these environments and tools to reduce disability brought on by a mismatch between individuals and their environments. These two goals entail both theoretical and applied research into three related areas: Participatory Material Culture, Sensory Information Processing and Adaptive Games and Inclusive Play. Semaphore is led by Director Matt Ratto (Faculty of Information) and Associate Directors Sara Grimes (Faculty of Information) and Rhonda McEwen (Institute of Communication, Culture and Information Technology). Semaphore is part of the CFI and ORF funded Inclusive Design Institute.
