I don't know whether the technology is there, but I could see AR glasses being paired with a (RFID? Bluetooth?) ring you wear as a pointing device. The demo uses speech but I haven't found the Google voice search very impressive so I have my doubts. Put it on your finger (or if a cheap and small RFID chip, glue it onto your fingernail, or even paint each of your fingernails with invisible slightly radioactive nail polish), pair it with your glasses and you can use your finger(s) as a pointing device in the AR overlay. Depending on input resolution, the movements could be subtle -- you don't have to raise your hands as if conducting an orchestra although that would be fun to see. Wiggle your fingers to control your headset. Or how about keyboard trousers. Invisible areas on the outside of your trousers that you can tap as a small 10-key keyboard.
