Abstract
Abstract Method of, and apparatus for, providing automatic detection of the physical presence of a user of a data processing system. The present invention comprises an Event Detection Process, a Presence Detection Process, and an Interrogator Process. The Event Detection Process detects presence indicating events. The Presence Detection Pro cess evaluates the presence indicating events to determine the physical presence of a user or someone else other than a user. The Interrogator Process provides an interface to a requestinguser and formulates appropriate queries to be sent to one or more Presence Detection Processes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
46 words
A method of providing automatic detection of a physical presence of a user of a data processing system comprising the steps of: detecting a presence indicating event in the data processing system; and evaluating the presence indicating event to determine the physical presence of a user.
Claim 2
Dependent Claim
98 words
The method of claim 1, wherein the step of evaluating the presence indicating event to determine the physical presence of a user, comprises the step of: determining if a presence indicating event occurs during a proximity interval, wherein the presence indicating event is an event which may occur in a data processing system and which may indicate the physical presence of a user within a physical area in proximity to a data processing system, and wherein the proximity interval is an interval of time required for a user to leave a physical area corresponding to the proximity interval.
Claim 3
Dependent Claim
34 words
The method of claim 2, wherein the presence indicating event is a verified event, wherein a verified event is a presence indicating event which requires a user's presence and is verified by a user.
Claim 4
Dependent Claim
35 words
The method of claim 3, wherein the step of evaluating the presence indicating event to determine the physical presence of a user, further comprises the step of: logging the presence indicating event in a database.
Claim 5
Dependent Claim
176 words
The method of claim 4, wherein the step of evaluating the presence indicating event to determine the physical presence of a user, further comprises the steps of: determining a user is physically present in a physical area corresponding to a proximity interval if there is not a time interval, between logged presenceindicating events since an occurrence of a verified event, greater than a proximity interval; determining someone is physically present in a physical area corresponding to a proximity interval if there is a time interval, between logged presence indicating events since an occurrence of a verified event, greater than a proximity interval; determining someone is physically present in a physical area corresponding to a proximity interval if a proximity interval is greater than a time interval since a last presence indicating event, but there is not a verified event logged for a user; and determining no one is physically present in a physical area corresponding to a proximity interval if a proximity interval is not greater than a time interval since a last presence indicating event.
Claim 6
Independent Claim
47 words
An apparatus for providing automatic detection of a physical presence of a user of a data processing system comprising: means for detecting a presence indicating event in the data processing system; and means for evaluating the presence indicating event to determine the physical presence of a user.
Claim 7
Dependent Claim
97 words
The apparatus of claim 6, wherein the means for evaluating the presence indicating event to determine the physical presence of a user, comprises: means for determining if a presence indicating event occurs during a proximity interval, wherein the presence indicating event is an event which may occur in a data processing system and which may indicate the physical presence of a user within a physical area in proximity to a data processing system, and wherein the proximity interval is an interval of time required for a user to leave a physical area corresponding to the proximity interval.
Claim 8
Dependent Claim
34 words
The apparatus of claim 7, wherein the presence indicating event is a verified event, wherein a verified event is a presence indicating event which requires a user's presence and is verified by a user.
Claim 9
Dependent Claim
34 words
The apparatus of claim 8, wherein the means for evaluating the presence indicating event to determine the physical presence of a user, further comprises: means for logging the presence indicating event in a database.
Claim 10
Dependent Claim
182 words
The apparatus of claim 9, wherein the means for evaluating the presence indicating event to determine the physical presence of a user, further comprises: means for determining a user is physically present in a physical area corresponding to a proximity interval if there is not a time interval, between logged presence indicating events since an occurrence of a verified event, greater than a proximity interval; means for determining someone is physically present in a physical area corresponding to a proximity interval if there is a time interval, between logged presence indicating events since an occurrence of a verified event, greater than a proximity interval; means for determining someone is physically present in a physical area corresponding to a proximity interval if a proximity interval is greater than a time interval since a last presence indicating event, but there is not a verified event logged for a user; and means for determining no one is physically present in a physical area corresponding to a proximity interval if a proximity interval is not greater than a time interval since a last presence indicating event.
