Peopletones: a system for the detection and notification of buddy proximity on mobile phones

Mobile phones have the potential to be useful agents for their owners by detecting and reporting situations that are of interest. Several challenges emerge in the case of detecting and reporting "nice to know" situations. Being alerted of these events may not be of critical importance but may be useful if the user is not busy. For detection, the precision of sensing must be high enough to minimize annoying false notifications, despite the constraints imposed by the inaccuracy of commodity sensors and the limited battery power available on mobile phones. For reporting, the notifications cannot be too obtrusive to the user or those in the vicinity. Peripheral cues are appropriate for conveying information like proximity, but have been studied primarily in settings like offices where sensors and cueing mechanisms can be controlled. We explore these issues through the design of PeopleTones, a buddy proximity application for mobile phones. We contribute (1) an algorithm for detec...
