This section deals with Human-Human interaction. As the wearable is quite new for the layman one has to expect some strange reactions from the other people. When I go out and read my PalmPilot's screen while walking or in the subway people have one of the following reactions :
No reaction: because they are in their own world or because they don't care.
Curiosity: they come to me and ask me questions like "what it is", "what are you doing with it" and "how much does it cost ?"
Disdain : they may think I want to draw attention.
Hostility/Fear : "this guy is nut: avoid him".
Steve Mann Gave an interview in the New Scientist magazine and as he was one of the first to test the waters, so he has a long experience in this field. The second problem is that the wearable's hardware is quite expensive and some predators will spot a new device that can be easily stolen and sold at a good price, or just in order to have one of them. As a conclusion you have to be very cautious.
