As our project relies heavily on the intersection of time and place, we decided early on to develop “augmented reality” applications for use with smartphones. If you are unfamiliar with the concept, Wikipedia defines augmented reality as:
Augmented reality (AR) is a term for a live direct or indirect view of a physical real-world environment whose elements are augmented by virtual computer-generated imagery. It is related to a more general concept called mediated reality in which a view of reality is modified (possibly even diminished rather than augmented) by a computer. As a result, the technology functions by enhancing one’s current perception of reality.
In the case of Augmented Reality, the augmentation is conventionally in real-time and in semantic context with environmental elements, such as sports scores on TV during a match. With the help of advanced AR technology (e.g. adding computer vision and object recognition) the information about the surrounding real world of the user becomes interactive and digitally usable. Artificial information about the environment and the objects in it can be stored and retrieved as an information layer on top of the real world view. The term augmented reality is believed to have been coined in 1990 by Thomas Caudell, an employee of Boeing at the time[1].
Augmented reality research explores the application of computer-generated imagery in live-video streams as a way to expand the real-world. Advanced research includes use of head-mounted displays and virtual retinal displays for visualization purposes, and construction of controlled environments containing any number of sensors and actuators.
Although the concept may seem like something from a science fiction film, users can now use smartphones (specifically smartphones with digital compasses, like the iPhone 3GS and Motorola’s Droid), and free apps (like Layar, Wikitude, Junaio, or Foursquare) to experience an “augmented” view of reality.
By June of 2010, Hershey Before Hershey will be publishing its own “layers” in Layar and Wikitude. These will allow users to instantly access the distance, direction, location, images, and additional information for Hershey Before Hershey “points of interest” in Derry Township.
