Headset

    From Consumerium development wiki R&D Wiki

    A headset is the only worn device that always accompanies a walkman and usually accompanies a cell phone or cordless phone. Use of a headset leaves both hands free, and can deliver audio from any of FM, AM, POTS, PCS, other cordless protocol, or IP based services.

    Therefore, it is the ideal way to deliver detailed information that is part of the Consumerium buying signal at the checkout counter or retail shelf. It might be possible for instance to put standard 1.5mm mono headset jacks and 2.5mm mono headset jacks at the counter, and make headsets available, if retailers cooperate. But more likely, it will be the buyer's own worn device that will relay this audio data to the headset.
