Worn device
A worn device is one that is ubiquitous and on the body all the time. Examples include:
- wristwatch
- ring
- wallet
- pager
- walkman
- cell phone
- cordless phone (in some environments supporting PCS protocol, the headset or handset is worn on the head or belt)
The term mobile device is often used to mean higher-tech worn devices, but there is no real difference in form factor, except that a mobile device is probably more likely to have a display screen capable of displaying more than one line, or an IP number, whereas most of the above don't.
The Consumerium buying signal will often be received by such a worn device. Although it would ideally be available at the checkout counter or retail shelf or some kiosk in between (inside the retail location), it seems unlikely that this would be available for pilot or early phases, or in hostile retailers who wish to keep selling red-light products without harassment. Accordingly the worn device will have to be supported regardless, and since it serves so many other purposes in the healthy signal infrastructure it seems wise to assume that the healthy buying infrastructure will primarily rely on these devices, and not on any in-store deployment of specialized devices (which probably will be deployed only by those who specialized in green light products anyway, and wish to convince buyers that they are in fact much better than the alternatives not recommended).
