Alternate use for the technology behind electronic paper:

1. Contact lens that serves as a "gel" between your eye and the world, tinting according to your needs. Polarizing?
2. Image enhancement/zoom.
3. Serving as a very personal data display.

Issues:

1. Power Source
2. Keeping everything oriented correctly
3. How thin can the lens be and still function without damaging the user?
4. Data I/O?

Combine this with a good HUD (Heads up Display) for the following possible uses:

1. Crime scenes - Police go in and record everything they can on the first pass through the location, then, later on, others can tour the area without disturbing the site, seeing it was it was at the time of discovery.
2. Tourism - Instead of having a taped tour (Like they do in Alcatraz) you could have a "live" tour, with the guide going along at your own pace.
3. Fitness trails and gyms could have instructors to show you how to use the equipment.
4. AI assistants for more personalized reminders.
