Personal cuing for spatially associated information

摘要

A method and system provides sensory cues to a user via a portable computing device as they wander a physical space, alerting the user as to the presence of spatially associated information linked to a location that is within a proximity region defined around that user's then current physical location. The size and/or shape of the proximity region can be defined in accordance with the speed and/or direction of motion of the user.
