This document discusses re-conceptualizing the e-textbook to enable ubiquitous interactions. It notes the increased digitization of learning materials but their lack of support for interaction across devices. The goals are to enhance learning through new technologies by designing an e-textbook for ubiquitous interaction using various digital artifacts. Research questions focus on how to design such interactions in education and evaluating the concept. Activities include studying current practices and iterating the design through field tests. Outcomes include understanding ubiquitous interactions and evaluating frameworks for designing them.
