Abstract
A method for the recording and retrieval of information relevant to the activities of a user. The invention may be employed to provide a memory prosthesis in the form of a highly portable device which records all kinds of information about the user's life, and provides a simple and rapid means of access to that information. The device receives and stores information from external sources, or objects, or from signal generators identifying specific machines, places, or people carrying other ones of the same type of device. Events comprising encounters between objects are recorded automatically, being time-stamped and stored chronologically, and a rapid search method for such a database is disclosed. The data can either be stored in the memory of the device itself, or, for better protection against failure, in a central data repository of the system, with a fail-safe backup.
