Cranial resistivity headphone activation

  [vote for,

Headphones connected to some sort of music player which puts a minute voltage across the two earpieces and only plays music when the measured resistance across the earpieces is close to the pre-calibrated resistance of your head. So, when you take your headphones off, the music is paused.

Interestingly related patent http://www.patently...-heart-sensors.html
This patent talks about the identification of the user of an electronic device by looking at characteristics of their heartbeat, including through picking this up through conductors in headphones or earbuds. [hippo, Jun 28 2010]

AKG K271 http://www.akg.com/...2,_language,EN.html
Headphones that turn off when you take them off. No, they don't pause the music. [Cedar Park, Jun 30 2010]


       In some cases, it would sense an open- circuit.

       This fails to take in to account the larger headed gentleman.
Also, I often prefer to listen to music using one headphone, so that I can pay semi-attention to the world around me. How would that work?

Did you miss the bit where it says 'pre-calibrated'?

       Yes [angel]. Yes I did.

       You could put two contacts on each 'phone and measure the resistance of the ear/side of head (depending on size of headphones). You'd need less power and wouldn't end up shoving it through your brain... unless that's the point?

       [st3f] that might be a better idea actually

       hippo: all part of the same general idea. Halfbrainstorming.

       Apart from the charm of micro-ECT, I don't understand how this improves on a simple pressure sensitive switch.

       Wouldn't a pressure sensor be simpler?

       Capacitance might work better.

       A simple microswitch does the trick for the AKG K271 heaphones. They turn off when you take them off your head. [link]
