MULTIPLE METER DETECTION AND PROCESSING USING MOTION DATA
First Claim
1. A computer-implemented method for determining multiple portable computing devices being physically carried by one person, comprising the steps of:
- receiving media exposure data over a data network from at least one of a plurality of portable computing devices;
receiving motion strings over the data network respectively from each of the plurality of portable computing devices, each of said strings comprising a successive binary representation of motion over a first period of time;
comparing the motion strings in a processor to determine if at least two motion strings match within a predetermined threshold; and
identifying the devices that produced matching motion strings.

Abstract
Systems and methods are disclosed for identifying users of portable user devices according to one or more accelerometer profiles created for a respective user. During a media session, the portable computing device collects media exposure data, while at the same time, collects data from the accelerometer and compares it to the user profile. The comparison authenticates the user and determines the physical activity the user is engaged in. Additional data may be collected from the portable computing device to determine one or more operational conditions of the device itself, including the detection of multiple devices being physically carried by one user. Gross motion strings may also be generated by devices and compared to see if strings match, thus suggesting multiple devices are being carried by one user.

13. A computer-implemented method, comprising the steps of:
-
receiving media exposure data from at least one of a plurality of portable computing devices; receiving segmented accelerometer data from the plurality of portable computing devices; extracting features from each of the segmented accelerometer data and forming accelerometer classification data for each portable computing device; comparing each of the accelerometer classification data to at least one of (i) accelerometer classification data for another portable computing device and (ii) a stored profile for another portable computing device to determine if accelerometer classification data for one portable computing device is sufficiently similar to another portable computing device; identifying the one portable computing device as having a duplicate user if the comparison step determines that the accelerometer classification data for the one portable computing device is sufficiently similar to another computing device. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
