Khai N. Truong - Beyond Google

Although the Web and hypertext has clearly transformed the way people solve many problems today, some content still does not exist in an electronic format available online. As a result, people sometimes face a diverse set of problems that they cannot solve easily by themselves as individuals. For example, a person may not be able to answer "if a stroller can be used on the Don Valley trail" after recent snowfall through any means other than trial and error. This talk will examine people's daily information needs and opportunities for addressing such highly situated and contextualized problems through the development of ubiquitous computing tools and infrastructure. I will discuss the technical and social challenges involved in the design and evaluation of a community-based service approach that leverages the knowledge and altruism of registered members to help others.
