1. A method comprising: receiving first sensor data from one or more sensors of a first computing device; receiving second sensor data from one or more sensors of a second computing device; determining, based on the first and second sensor data, that the first and second computing devices are colocated with one another; identifying, based on the first sensor data, a context associated with the first computing device; and identifying, based at least in part on the context associated with the first computing device, a context associated with the second computing device.
