Abstract
One embodiment of the present invention provides a system for determining venue information associated with a mobile device user. During operation, the system collects contextual information recorded by one or more sensors located on the mobile device and extracts a behavior pattern of the user as a function of time and/or an environmental indicator based on the collected contextual information. The system then compares the behavior pattern and/or the environmental indicator with known behavior patterns and/or environmental indicators associated with a number of venues stored in a database, and determines a venue associated with the user based at least on the comparison.
Claims20
A computer-executable method for determining venue information associated with a mobile device user, the method comprising:
- collecting contextual information recorded by plurality of sensors located on the mobile device, wherein the sensors include a global positioning system (GPS) sensor;
- extracting a behavior pattern of the user as a function of time and/or an environmental indicator based at least on the collected contextual information;
- comparing the behavior pattern and/or the environmental indicator with known behavior patterns and/or environmental indicators associated with a number of venues stored in a database;
- determining a venue associated with the user based at least on the comparison;
- and
- determining whether the user enters and/or exits the venue based on a dilution of precision (DOP) value of the GPS sensor.
A system for determining venue information associated with a mobile device user, comprising:
- a plurality of sensors for collecting contextual information, wherein the sensors include a global positioning system (GPS) sensor;
- an extraction mechanism configured to extract a behavior pattern of the user as a function of time and/or an environmental indicator based at least on the collected contextual information;
- a database storing known user behavior patterns and/or environmental indicators associated with a number of venues;
- and
- a determination mechanism configured to determine a venue associated with the user based at least on a comparison between the extracted behavior pattern and/or environmental indicator and the ones stored in the database,. wherein the determination mechanism is further configured to determine whether the user enters and/or exits the venue based on a dilution of precision (DOP) value of the GPS sensor.
A server facilitating determination of venue information associated with a mobile device user, comprising:
- a receiving mechanism configured to receive contextual information recorded by a plurality of sensors located on the mobile device wherein the sensors include a global positioning system (GPS) sensor;
- an extraction mechanism configured to extract a behavior pattern of the user as a function of time and/or an environmental indicator based at least on the collected contextual information;
- a database storing known user behavior patterns and/or environmental indicators associated with a number of venues;
- and
- a determination mechanism configured to determine a venue associated with the user based at least on a comparison between the extracted behavior pattern and/or environmental indicator and the ones stored in the database, wherein the determination mechanism is further configured to determine whether the user enters and/or exits the venue based on a dilution of precision (DOP) value of the GPS sensor.
