The memory glasses : wearable computing for just-in-time memory support

Thesis (Ph. D.)--Massachusetts Institute of Technology, School of Architecture and Planning, Program in Media Arts and Sciences, 2004.Includes bibliographical references (p. 173-181).This thesis documents a body of wearable computing research surrounding the development of the Memory Glasses, a new type of proactive memory support technology. The Memory Glasses combines features of existing memory support technologies (such as PDAs) with a context aware delivery system and a low-attention cuing interface. The goal of the Memory Glasses is to provide effective just-in-time memory support while mitigating some of the distraction and over-reliance problems that can result from the use of more conventional memory support technology. The Memory Glasses research is a synthesis of the author's six years of work on wearable computing. This thesis documents the author's intellectual contributions in the areas of wearable computing hardware architectures, software architectures, and human-computer interaction. Specific topics include the MIThril wearable computing research platform, the Enchantment middlewear, the MIThril Real-Time Context Engine, the author's modified Seven Stages of Action model and five principles of low-attention wearable human computer interaction, as well as the author's research in the use of subliminal cuing for just-in-time memory support. Although memory support is the unifying theme of this dissertation, the author's research has seen application in a number of other areas, including the mapping of social networks, research in human physiology and biomedical applications, and group situation awareness and command, control, and communications. A selection of these applications is briefly presented as support for the importance of the author's intellectual contributions.by Richard W. DeVaul.Ph.D
