Where You Are Is Who You Are? The Geographical Account of Psychological Phenomena

Where Are You?

Two experiments revealed how nonexperts interpret visualizations of positional uncertainty on GPS-like displays and how the visual representation of uncertainty affects their judgments. Participants were shown maps with representations of their current location; locational uncertainty was visualized as either a circle (confidence interval) or a faded glyph (indicating the probability density fu...

The ability of robots to quickly and accurately localize their neighbors is extremely important in swarm robotics. Prior approaches generally rely either on global information provided by GPS, beacons, and landmarks, or complex local information provided by vision systems. In this paper we provide a new technique, based on trilateration. This system is fully distributed, inexpensive, scalable, ...

Where you stop is who you are: understanding people’s activities by places visited

The increasing availability of people traces collected by portable devices poses new possibilities and challenges for the study of people mobile behaviour. However, the raw data produced by such portable devices is poor from a semantic point of view, thus the gap between the person’s activity and the raw collected data generated by the activity is still too wide. The work presented in this pape...

One traditional answer is that an identity is a name. That’s unsatisfactory, for several reasons. First, a name points to an object—an entity—but is not itself that object. Second, authentication is needed...
