Forget the iWatch. A recently published Apple patent details an interesting health-monitoring device built into a pair of headphones or earbuds.

Along with being able to track user activity during exercise, the proposed technology can sense other biometric data like temperature, perspiration, and heartbeat.

And at least one embodiment of the technology features control with head gestures, according to the filing:

As a method for controlling an electronic device though one or more head gestures, one embodiment of the invention can, for example, include at least: receiving head motion data pertaining a head motion of a user of the electronic device; determining whether the head motion data matches any of a plurality of predetermined head gestures; and identifying an action associated with the matching predetermined head gesture. Additionally, the method can further operate to perform the identified action on the electronic device.

Entitled “Sports monitoring system for headphones, earbuds and/or headsets,” one of the more interesting facts from the patent is its original filing date of Aug. 21, 2008. That shows Apple has been interested in activity tracking technology for almost six years. Christopher Prest and Quin C. Hoellwarth are listed as the inventors on the patent.

As the wearable technology market has continued to heat up, Apple is reportedly hard at work on a so-called iWatch that could possibly contain many similar technologies.
