Abstract
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.

156 words
An information recording and retrieval system, comprising: a database for storing information; and a plurality of objects, each representing a user or other entity identifiable by the system, each object representing a user being portable, each object comprising: an agent; means for communicating between said agent and agents of other objects; and means for communicating between said agent and said database; and a user interface for communicating between a user of said object and said agent; wherein said information to be recorded is organized as a set of threads, each thread comprising a chronological sequence of time-stamped facts all of which relate to a single object and at least some of which also represent descriptors of other objects, each fact including an attribute and a value of that attribute for said given object at the time indicated by said time-stamp, said facts being automatically recorded in said database upon physical collocation of two or more objects.
Claim 2
Dependent Claim
156 words
An information recording and retrieval system, comprising: a database for storing information; and a plurality of objects, each representing a user or other entity identifiable by the system, each object representing a user being portable, each object comprising: an agent; means for communicating between said agent and agents of other objects; and means for communicating between said agent and said database; and a user interface for communicating between a user of said object and said agent; wherein said information to be recorded is organized as a set of threads, each thread comprising a chronological sequence of time-stamped facts all of which relate to a single object and at least some of which also represent descriptors of other objects, each fact including an attribute and a value of that attribute for said given object at the time indicated by said time-stamp, said facts being automatically recorded in said database upon physical collocation of two or more objects.
Claim 3
Dependent Claim
21 words
The system of claim 1, further including means to enable manual entry of said facts or other information into said database.
Claim 4
Dependent Claim
18 words
The system of claim 1, further including means for automatically recording facts in said database at predetermined times.
Claim 5
Dependent Claim
23 words
The system of claim 1, further including means for automatically recording facts in said database on occurrence of predetermined values of an attribute.
Claim 6
Independent Claim
211 words
A method of searching for information using a first object that is portable, the first object including an agent, a database, a first means for communicating between the agent and other objects, a second means for communicating between the agent and the database, and a user interface for communicating between the agent and a user of the first object, the database being organized as a set of threads, each thread including a chronological sequence of time-stamped facts, each fact relating to a single object and at least some of which also represent descriptors of other objects, each object representing a person or an identifiable entity, and each of said facts comprising an attribute and a value of that attribute for a given object, the method comprising the steps of: a) displaying the sequence of facts of a selected thread, or the sequence of events defined by coincidence of two or more threads in response to a first request from the user of the first object; b) moving selectively forward or backward in time through the displayed sequence of facts or events in response to a second request to the user of the first object; and c) enabling selection, for subsequent display, of any one of said threads of a displayed event.
Claim 7
Independent Claim
211 words
A method of searching for information using a first object that is portable, the first object including an agent, a database, a first means for communicating between the agent and other objects, a second means for communicating between the agent and the database, and a user interface for communicating between the agent and a user of the first object, the database being organized as a set of threads, each thread including a chronological sequence of time-stamped facts, each fact relating to a single object and at least some of which also represent descriptors of other objects, each object representing a person or an identifiable entity, and each of said facts comprising an attribute and a value of that attribute for a given object, the method comprising the steps of: a) displaying the sequence of facts of a selected thread, or the sequence of events defined by coincidence of two or more threads in response to a first request from the user of the first object; b) moving selectively forward or backward in time through the displayed sequence of facts or events in response to a second request to the user of the first object; and c) enabling selection, for subsequent display, of any one of said threads of a displayed event.
Claim 8
Dependent Claim
