Our body attitude communicates a number of emotions to the people close to us or to our image. Our clothes also convey a message, but this medium has usually a 24 hr delay, and sometimes we wish there was a faster and more efficient method. Even the wedding ring with its important message sometimes resists being pulled out of our finger…
However, these primitive ways can be enhanced by modern electronics. How about a hat with directional lights and radio waves, able to communicate with similar hats around? It can offer help to tourists, a drink to attractive potential partners, chat to other bored people. It could even ask for a doctor or other professional.
A further step would be the hats to interact with our profile in a web site, for couple matching or professional purposes.
“Sorry, your hat says you are a mechanic. Could you help me with my car?”.
Just an idea.
