The goal of this project is to allow a user with a bluetooth enabled cellphone or pda to gather personally relevant information about and interact with inanimate objects such as books, tabletops, works of art, etc in the user's vicinity.The system allows the user to passively gather information about their environment and get just-in-time reminders or suggestions from useful objects in the environment. For example, walking into a room full of augmented books, the books of interest to the user would "blink" their LEDs, thereby making it easier for the user to find books of potential interest.
