Architecture & techniques for automatically capturing, sensing, and sharing information from daily life

One major theme of research in ubiquitous computing is capture and access, that is the recording of details from daily life and then providing interfaces for reviewing that information at a later time. Much of the existing work in this area has investigated issues relevant to the capture and access of information for individual users. The capture and sharing of information between users within a community, however, has not been explored to the same extent and presents novel research questions. In particular, collaborative capture and access can result in a compilation of collective knowledge that can assist in addressing problems that individual users may not have enough information to solve. For instance, a traditional capture and access application for the car may involve instrumenting an automobile to capture images when in operation. This enables the owner to later review drives between locations she has visited. Users looking up directions to places they have not yet visited, however, may want access to similar levels of detail in the form of textual directions coupled with a preview of the images and landmarks for the drive. This level of detail can be collected over time if each individual in a community of users captures and shares images from their daily experiences on the road. Furthermore, a user may want to preview images for a drive that no individual user has previously made, but information captured by multiple users can be combined to provide the desired result. Such requirements present unique challenges above and beyond those already present in systems supporting the capture and access of information for individual users. The proposed research involves design, development, and evaluation of interaction and sensing techniques and an architecture for automatically sensing, capturing, and annotating information from daily life in ways that afford collective use by a community of users. Subsequent application development can be used to validate the generalizability of the architectural solution and enable evaluation of the usability and effectiveness of the techniques in real use settings.
