Abstract

An information delivery system comprises a receiver component that receives information about the movement, velocity, acceleration, and/or locations over time of a user. A computation component using a predictive model generates a probability distribution relating to one or more of when the user will next be stopped, how long the user will be stopped, how long a pattern of motion, such as walking, driving in stop and go traffic, and smooth highway motion will last, based at least in part upon signals about motion over time. The system can further comprise an alerting component that determines when to provide the user with information based at least in part upon the probability distribution over some aspect of motion or cessation of motion, and optionally the content, or tagged or inferred urgency or importance, of a message or communication.

Claims

1. An information delivery system comprising:

at least one processor executing the following computer-executable components;

a receiver component that receives information about at least one of movement, velocity, acceleration, and location of a user over time;

a computation component that determines a time when the user will be stopped based at least in part upon the received information; and

an alerting component that determines when to provide the user with an alert based at least in part on a cost associated with deferring provision of the alert to the user, wherein the cost is based at least in part on availability of the user to review the alert, and the availability of the user is determined based at least in part upon the determined time when the user will be stopped.

2. The system of claim 1, wherein:

the receiver component receives an indication that the user is stopped from a sensor;

the computation component generates a probability distribution relating to how long the user will remain stopped based at least in part upon the received information about at least one of movement, velocity, acceleration, and location of the user over time.

3. The system of claim 2, wherein the alerting component determines when to provide the user with the alert based at least in part upon the probability distribution relating to how long the user will remain stopped.

4. The system of claim 1, wherein the information about at least one of movement, velocity, acceleration, and location of the user over time is obtained from one or more of a car speedometer, an accelerometer, and a GPS system.

5. The system of claim 1, wherein:

the receiver component receives an indication that the user is moving from a sensor,

the computation component generates a probability distribution relating to when the user will become stopped and a length of the stop based at least in part upon the information about at least one of movement, velocity, acceleration, and location of the user over time.

6. The system of claim 5, wherein the alerting component determines when to provide information to the user based at least in part upon the probability distribution relating to when the user will become stopped and a length of the stop.

7. The system of claim 1, wherein the computation component comprises a transition component that determines at least one of when the user will transition between traffic patterns and a length of time the user will reside within a particular traffic pattern.

8. The system of claim 1, wherein the alerting component determines when to provide the user with information based at least in part upon one or more predefined rules.

9. The system of claim 1, further comprising:

a valuation component that analyzes content of the alert to generate a measure of value of the alert.

10. The system of claim 1, wherein:

the alerting component comprises a deferral component that determines a measure of the cost associated with deferring provision of the alert to the user.

11. An electronic device comprising a notification system, the device comprising:

a display;

a processor;

a computer readable storage medium encoded with computer executable instructions that, when executed by the processor, perform a method comprising;

receiving a parameter through a user interface, the parameter defining a user preference for receiving messages while in an automobile;

sensing conditions associated with a user;

projecting a characteristic of a user stop based on the sensed conditions;

determining whether to present a message to the user based on the projected characteristic of the user stop and the user preference; and

selectively presenting the message to the user, the selectively presenting comprising, based on the determining;

under a first condition of the projected characteristic of the user stop and the user preference, presenting the message to the user while the user is driving the automobile; and

under a second condition of the projected characteristic of the user stop and the user preference, deferring delivery of the message to the user until the user is stopped.

12. The electronic device of claim 11, wherein the parameter indicates a minimum projected duration of a stop during which the user wishes to receive messages.

13. The electronic device of claim 12, wherein the parameter indicates a maximum projected time until a stop during which the user wishes to defer receipt of messages.

14. The electronic device of claim 12, wherein the determining further comprises:

analyzing content of the message to determine a cost of deferring delivery of the first message until a projected stop meeting the user preference.

15. The electronic device of claim 12, wherein receiving the parameter further comprises receiving user input indicating a context in which the user preference applies.

16. A method for delivering information to a user, the method comprising, with at least one processor:

receiving information about at least one of movement, velocity, acceleration, and location of a user over time;

determining, by the at least one processor, when the user will be stopped based at least in part upon the received information; and

determining, by the at least one processor, when to provide the user with an alert based on a cost of disrupting the user with the alert and a cost of deferring provision of the alert to the user, wherein the cost of deferring is based at least in part on availability of the user to review the alert, and the availability of the user is determined based at least in part upon the determined time when the user will be stopped.

17. The method of claim 16, further comprising:

receiving an indication that the user is stopped from a sensor; and

generating a probability distribution relating to how long the user will remain stopped based at least in part upon the received information about at least one of movement, velocity, acceleration, and location of the user over time.

18. The method of claim 17, wherein:

determining when to provide the user with the alert comprises determining when to provide the user with the alert based at least in part upon the probability distribution relating to how long the user will remain stopped.

19. The method of claim 17, further comprising:

determining at least one of when the user will transition between traffic patterns and a length of time the user will reside within a particular traffic pattern.

20. The method of claim 17, further comprising:

analyzing content of the alert to generate a measure of value of the alert, wherein;

determining when to provide the user with the alert based on availability of the user to review the alert further comprises determining when to provide the user with the alert based on the measure of value of the alert.
