Abstract: Design research in human-computer interaction uses successive implementations of an innovation to test and refine designs as well as the principles of interaction that the designs are based upon. This progressive refinement in the designed artifacts and the principles of interaction involves putting a first version of a system into practice to see how it works. Then, the design and the principles of interaction are successively revised based on findings. This report describes the approach, efforts and lessons learned from a multi-year effort to develop a contextaware activity notification system for online learning.
Key words: design research;context awareness;human computer interaction;online learning; social computing
