Constructing and sharing everyday memory for community knowledge co-evolution

The authors describe a method for supporting the process of accumulating personal everyday memory and sharing it in a community. Two ideas are used to implement the method. The first idea is intimate computing which enables people to externalize and accumulate personal memory using associative representation at any time and any place. The second idea is a talking virtualized egos metaphor that visualizes community knowledge interaction. This helps community members to find out common interests and shared knowledge. Based on these ideas, we developed the system called CoMeMo which helps people to manage personal and community memory. In experimentation, we observed the following: (a) collaborative knowledge building, (b) change of shared information, (c) creation of new human relationships.
