This is a gadget I think I'd like to wear. It's a novel kind of phone headset. The watchband would have a microphone on the inner part of the wrist. On my thumb or forefinger would be a ring with a speaker, BT connected to the watchband and the cell phone in my pocket, purse, etc. After checking caller ID on the watch's face, I could answer my phone simply by holding my hand up to the side of my face, with the ring near my ear and the bracelet near my mouth. Same for calling out. It would mean that I wouldn't have to walk around with a conspicuous, uncomfortable headset clipped to my ear. Or fumble for my phone.
If anyone manufactures such a gadget, please send me one as a Thank You.
