First Claim
1. A computer assisted method, comprising the steps of:
- receiving at a mobile computer system positioning information corresponding to the geographic location of said mobile computer system;
storing a task description comprising an action item in a database so as to associate said task description with said position information; and
retrieving said task description when said mobile computer system is in a second geographic location that is within a selected range of a location at which said task description may be performed.

Abstract
A task description is stored in a database accessible by a mobile computer system. The mobile computer system receives positioning information corresponding to its geographic location and indexes the database based on the positioning information when the information indicates that the mobile computer system is in a geographic location that facilitates completion of a task associated with the task description. The database may be resident in the mobile computer system or accessible in other ways, for example, via the Internet. The task description preferably includes a geocode which corresponds to the geographic location at which completion of the task may be facilitated. The task description may also include textual, voice or other message which can be displayed and/or played back to a user. The positioning information may be obtained from a GPS satellite, a GLONASS satellite or a pseudolite. The mobile computer system may be a portable unit, such as a PDA, or integrated within a vehicle.

21. A computer assisted method, comprising the steps of:
-
transporting a mobile computer system to a first location having first geographic coordinates at a first time; receiving and processing at said mobile computer system a first set of RF signals to derive said first geographic coordinates; and retrieving a previously entered task description from a database if said first geographic coordinates indicate that said mobile computer system is within a selected range of a location at which a task associated with said task description may be accomplished. - View Dependent Claims (22, 23, 24, 25)

26. A mobile computer system, comprising:
-
a location determination unit configured to receive and process RF signals to derive a set of location coordinates corresponding to the location of said mobile computer system; and means for retrieving a task description from a database coupled to said location determination unit when said location coordinates indicate said mobile computer system is within a selected range of a location at which said task description was stored. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)

35. A computer assisted method of scheduling a task, comprising the steps of:
-
storing, over a period of time, commute information indicative of a regularly travelled route of a vehicle, said commute information comprising one or more position information entries, each position information entry derived from positioning information received from a GPS receiver; storing one or more vehicle stop entries for said vehicle, each vehicle stop entry being associated with a location at which a task is performed, each vehicle stop entry including positioning information received from said GPS receiver; associating with said vehicle stop entries, task descriptions, each task description being indicative of a task capable of being accomplished at a location associated with an associated vehicle stop entry; and retrieving one of said task descriptions using first positioning information received from said GPS receiver when said first positioning information indicates that said vehicle will be in a first location within a predefined range of one of said locations associated with one of said vehicle stop entries, wherein said first positioning information is used in conjunction with said commute information to determine that said vehicle will be in said first location.
