RockoW writes "Steve Mann, a long-time researcher of computer vision systems, (i.e. Augmented reality, Digital Eyeglass) had an incident at a McDonald's in Paris, France. He was assaulted by three men during his visit to get food with his family. They had a problem with his digital eye glasses and tried to take them off his head. 'The eyeglass is permanently attached and does not come off my skull without special tools.' The men also tore up Mann's documentation and a letter from his doctor explaining the device's use. Fortunately, the rough treatment of the device caused it to keep recent images in its memory, instead of quickly overwriting them, so Dr. Mann has pictures of the men who assaulted him."

simple heuristics you have to remember...
Yes, don't fall out, and don't hit rocks.
