I know I said I'd wait to post participatory panopticon-related pieces until I had several to do together, but I couldn't wait on this one: Olympus is now testing a very light-weight wearable "head mounted display" (HMD). As described on Wonderland:
To explain the system briefly: it projects information on your glasses (normal or sunglasses). The goal here is to project everyday use data like train schedules or the arrival of an email or whatever else you might want. We can imagine a system that incorporates a database with information about the city and that gives information about the area where you are situated, possible hooked up to a GPS system and a system that detects what the eye is looking at.
Asian technology news website Tech-On has more:

The HMD usually does not display anything but shows simple information on certain occasions, e.g. to notify the arrival time of the train when the user comes to the station platform, or to draw attention when the user receives an e-mail. A 3.8-inch translucent screen with a diagonal length of 10 cm seems to exist 50 cm ahead of the user. When actually worn, the impression is that there is almost no annoyance, things can be seen easily through the display and it never hinders sight.
Wearable displays are just as important to the rise of the participatory panopticon as wearable cameras. It's not enough to simply record and archive what you see -- you need to be able to play it back as necessary, fully augmented and annotated. The Olympus HMD is the least obtrusive one I've seen yet, and clearly gets us closer to a point where this sort of display is integrated right into one's glasses/sunglasses.
Note that these could be useful even without ubiquitous wearable cameras. An RFID tag or barcode reader and wireless connection could make them the ultimate tool for careful shoppers...
