The Virtual Observer is an unobtrusive, logging-based observation framework for mobile applications, which I designed and developed during my PhD. It basically consists of the Virtual Observer observation library for Android, and the Context Player, a data playback tool. I’ve used these tools to study several observation techniques and to investigate how valuable insights can be extracted from the recorded logging data. The plan is to make everything available as open source, soon. In the meantime, drop me a line if you are interested in trying the framework.
