Alumni campus tour: capturing the fourth dimension in location based notification systems

When a person visits a place, it is almost always simple to understand the physical environment around them. Often people ignore---or don't have access to---the fourth dimension: time. Our research is an attempt to create a system that adds the aspect of time into location-based notification systems. This allows a person to not only experience their surroundings through five senses and three dimensions, but also to understand the changes the location has undergone over time, by receiving cues. This report describes our experience in designing and implementing such a system and reports on a preliminary evaluation of it.
