Hi guys, a friend of mine and I are trying to create a bracelet with some sensors that allows people to control other devices with their finger movements.

I got different doubts:

Do you think can be useful for hunting ?
In case it does, how would you realize? a whole bracelet or just a module that can bu put under the watchband?
Color? material?
what is the most frustrating thing that occur when you are hunting and involves the technology that you usually use?
thank you very much guys hope you can help me to sorti it out!

Nicola
