Data fusion for personal air pollution exposure
First Claim
1. A system for measuring and viewing air pollution exposure for a user, the system comprising:
- a data center comprising one or more computer servers;
means, associated with the user, for communicating user location data to the data center via a computer network;
a plurality of air quality sensors that each transmit air quality data to the data center via the computer network; and
a graphical display device that is in communication with the data center via the computer network, the graphical display device displaying a user interface for annotating an activity type according to time;
wherein the data center is programmed to;
receive the activity type from the graphical display device via the computer network;
receive the user location data from the means for communicating user location data to the data center, the user location data indexed in terms of time;
receive the air quality data from the plurality of air quality sensors, the air quality data indexed in terms of location of each of the air quality sensors and time;
calculate user air quality exposure measures for the activity type based on at least the air quality data for the location and time corresponding to the user location data; and
transmit the calculated user air quality exposure measures to the graphical display device for display by the graphical display device according to the activity type and the user location data.

Abstract
Systems and methods collect time and location indexed (spatiotemporal) air quality measurements for an individual and aggregate those measurements to obtain cumulative air quality exposures for the individual that are presented to the individual with an interactive graphical display. A plurality of air quality sensors each transmits air quality data to the data center. The air quality sensors can comprise both indoor and outdoor air quality sensors. The data center stores the temporally-indexed user location information and the spatiotemporally-indexed air pollution information from the air quality sensors. Based on this information, it calculates user air quality exposure measures and transmits them to a graphical display device associated with the individual so that the individual can visualize his/her pollution exposure over time. Where the data center has information on the individual'"'"'s activities at certain times, it can compute and display for the individual air quality exposure measures by activity type. The calculations can use a K-nearest neighbor algorithm to compute the individual'"'"'s air quality exposures.
