People Watcher has been created specifically for real-time recording of navigational/wayfinding behaviors in buildings and outdoor environments. This is an App to help researchers, environmental psychologists and architects understand how people navigate in complex environments. You can use it to undertake wayfinding or navigation experiments in buildings (airports, hospitals, train stations etc.). With this App you can only observe the behaviour of a single participant at a time. Use your finger or stylus to trace the participants path through the environment using the "Map Page". Buttons at the bottom of the "Map Page" facilitate the recording of significant wayfinding behaviours or events (such as pausing, looking at signs or consulting maps). Analytic tools on the "Analysis Page" have been provided to allow you to view all participant-paths simultaneously, i.e. overlaid on each other, in order to rapidly detect patterns or clusters of events (by eye). You can upload your own plans from your photo collection, to a maximum of 9 plans (so, for a multi-level building, a maximum of 9 floors). All paths and events are time-stamped and their location noted in a log file which can be exported via iTunes.
