The glasses need to be seen as the IO of the computer attached. You wear your earphones but they are not the computer. They may have a microphone, a few buttons, and sometimes camera, but they are attached to your smartphone or whatnot. So with the smart glasses. A wire, behind the ear, under the clothes, to the smartphone, and be done with it. Easy, and preferable too. Detachable at the glass part, detachable at the pocket part, and smart clothing would mean just the clothes with the wires laid out already for the typical audio/video stream between the glasses and the smart brain powering them.
