Abstract: The disclosure includes a system and method for detecting fine grain copresence between users. The system includes a processor and a memory storing instructions that when executed cause the system to: transmit a wakeup signal to a plurality of devices based on coarse grain location information; send a request to a first device of the plurality of devices to transmit a token using a first communication technology to determine fine grain copresence; receive a first token acknowledgment from a first subset of the plurality of devices; send a request to a second device of the first subset of the plurality of devices to transmit the token using a second communication technology to determine fine grain copresence; receive a second token acknowledgment from a second subset of the plurality of devices; and refine copresence based on receiving the first and second token acknowledgment.

Abstract: Example methods and systems for determining media files based on activity levels are described. An example method includes receiving information indicative of a first speed of the computing device, and receiving information indicative of a geography of a location of the computing device. The method further includes determining, from a plurality of media files tagged with respective tempo identifiers, a first media file based on the geography of the location of the computing device and also having a tempo that substantially matches to the first speed of the computing device. The method includes providing an indication of the first media file to a media player, and based on a change in the first speed of the computing device to a second speed, determining from the plurality of media files tagged with respective tempo identifiers, a second media file having a tempo that substantially matches to the second speed.
