First Claim
1. A system for detecting multiple portable computing devices being physically carried by one person, the system comprising:
- an input to receive media exposure data from a first one of a plurality of portable computing devices;
the input to receive segmented accelerometer data from the plurality of portable computing devices, the segmented accelerometer data segmented based on accelerometer data associated with at least one of walking, stopping, running, or sitting;
a processor, operatively coupled to the input, to extract features from the segmented accelerometer data, the processor forming accelerometer classification data for respective ones of the plurality of portable computing devices based on the extracted features;
the processor to compare the accelerometer classification data for the first portable computing device to at least one of (i) the accelerometer classification data for respective ones of the plurality of portable computing devices and (ii) stored accelerometer classification data for respective ones of the plurality of portable computing devices, to determine if accelerometer classification data for the first portable computing device is sufficiently similar to a second one of the plurality of portable computing devices;
the processor to identify the first portable computing device and the second portable computing device as being physically carried by a same person when the comparison determines that the accelerometer classification data for the first portable computing device is sufficiently similar to the accelerometer classification data for the second portable computing device; and
in response to identifying the first and second portable computing devices as being carried by the same person, the processor to credit the media exposure data for one of the first portable computing device or the second portable computing device, thereby reducing inaccurate media measurement results.

Abstract
Systems and methods are disclosed for identifying portable devices carried by the same person. An example method includes receiving media exposure data from one of a plurality of portable computing devices. Receiving segmented accelerometer data from the plurality of portable computing devices. Forming accelerometer classification data for the plurality of portable computing devices based on features extracted from the segmented accelerometer data. Comparing the accelerometer classification data for the first portable computing device to accelerometer classification data for the plurality of portable computing devices, to determine if the accelerometer classification data for the first portable computing device is sufficiently similar to a second portable computing devices. The example method further includes identifying the first and second portable computing device as being physically carried by a same person when the comparison determines that the accelerometer classification data for the first portable computing device is sufficiently similar to the second computing devices.
