## Abstract

A system for automatic proximity-based preloading of relevant information in portable devices pre-loads a portable device such as a mobile telephone, a personal digital assistant (PDA) or portable computer before the occurrence of a trip or event, with information relevant to the user's current or upcoming tasks. The system locates and loads into the portable device only the information required by the user for near term projects, meetings, or trips. The system is generally comprised of an information catalog, a proximity estimator, a relevance estimator, an information retriever, and a device loader. The information catalog contains a list of the information sources and items to which the user has access and from which the system of the invention will retrieve data to be loaded into the mobile device. The proximity estimator determines the proximity of various relevant information items to the user's tasks based on distance, time, and/or association. The relevance estimator combines these proximity measures into a single relevance score. The most relevant information is retrieved by the information retriever and loaded onto the portable device by the device loader.

## Claims

### Claim 1

A method for automatic relevance-based preloading data to a computing device, comprising:
identifying any one or more of persons or current scheduled tasks prior to the occurrence of the tasks;
analyzing the relevance of stored data to any one or more of the current scheduled tasks or persons;
sorting the stored data based upon the relevance to any one or more of the current scheduled tasks or persons;
setting a predetermined relevance threshold;
automatically preloading selected sorted data to the computing device with a relevance score higher than the relevance threshold; and
wherein analyzing the relevance score comprises estimating a proximity of the stored data items to any one or more of persons or current scheduled tasks, based on an association proximity measure and at least one proximity measure.

### Claim 2 (depends on 1)

The method of claim 1, wherein analyzing the relevance includes estimating a proximity of the stored data items to the any one or more of persons or current scheduled tasks, based on the combination of three proximity measures: distance, time, association.

### Claim 3 (depends on 1)

The method of claim 1, wherein analyzing the relevance further includes combining the at least three proximity measures into a single relevance score.

### Claim 4 (depends on 1)

The method of claim 1, wherein analyzing the relevance includes analyzing the proximity of information items to any one or more of the current scheduled tasks or persons.

### Claim 5 (depends on 1)

The method of claim 1, wherein analyzing the proximity of information items includes measuring proximity in terms of a combination of the association measure along with any one of location and/or time.

### Claim 6 (depends on 1)

The method of claim 1, wherein preloading selected sorted data to the computing device includes preloading the data to a communication device.

### Claim 7 (depends on 6)

The method of claim 6, wherein preloading the data to the communication device includes preloading the data to a mobile telephone.

### Claim 8 (depends on 6)

The method of claim 6, wherein preloading the data to the communication device includes preloading the data to a personal digital assistant (PDA) device.

### Claim 9 (depends on 1)

The method of claim 1, wherein preloading the data includes preloading the data to a personal computer.

### Claim 10 (depends on 1)

The method of claim 1, wherein identifying any one or more of current scheduled tasks or persons includes identifying events scheduled in a user's calendar, locations, and/or time frames.
