Title : Scrubby: Software to Analyze Multi-stream Logs of Experiments
One July, in a fit of PhD procrastination, I wrote an interactive software application (which I call "Scrubby") to synchronize, playback, and annotate multiple streams of logged data from an observational study I had just run. It was a study of Tablet PC usage with real software applications, and it produced 4 streams of logged data: a screen capture video, video taken from a head mounted camera, 3D Vicon tracking data, and a log of pen events and movements. It proved very useful for efficient formal coding of observations, and I extended it to enable multiple coders. Since then, I continued to refine it and used it for several other studies, including formal controlled experiments where I have found it invaluable. The latest version enables me to observe experimental trials in a non-linear fashion making it easier to investigate causes of statistical trends in the aggregate data. In this talk I will demo the latest version with log examples from a whole body interaction study I have been running.
