“Our study revealed unexpected uses of location-aware reminders. We found that Place-It notes were often used for creating motivational reminders to perform activities that would vary in priority over time. This is similar to using post-it notes in highly visible areas for motivation. The locations for motivational reminders were often set at frequently visited places, such as ‘home’. We also found that a majority of the uses for Place-Its involved communicating with people through a variety of media (e.g. email, phone). Communication is typically not tied to specific locations, implying that location is being used as a cue for other kinds of situational context.”
