Stay-in-touch: a system for ambient social reminders

Social interactions among a group of friends will typically have a certain recurring rhythm. Most people interact with their own circle of friends at a range of different rates, and through a range of different modalities (by phone, instant messaging, face-to-face meetings etc.). When these naturally recurring interactions are maintained effectively, people feel at ease with the quality and stability of their social network. Conversely, when a person has not interacted with one of their friends for a longer period than they usually do, a problem can be identified in that relationship which may require action to fix. We present Stay-in-touch, an ambient information system which provides peripheral cues to the user which serve as occasional recommendations of which of their friends they should contact soon in order to keep their social network in a healthy state.
