This extension is the first of its kind in Britain to investigate the effects of multitasking. It studies how people interact with the Internet and their ability to switch between activities on a given website. This is done by sending recorded messages to the zeitgeist messaging service, which relays messages to the zeitgeist daemon, which logs and reports the activity in a data archive.

This extension uses a native messaging host to relay recorded events to the zeitgeist daemon. The events contain a unique signature that allows the study to identify the behavior, and are not suitable for use with the vanilla zeitgeist activity journal.
