Physically make contact as in, tap it with your hand TNG style? Or worse, hold contact with your hand? How do you project the laser display and talk without using both hands? Is the hand criss crossing difficult I'm this situation?

An LED comes on... Is it bright? Can you see it direct line of sight from your eye to your shirt without fussing with it? Is the LED just there for others to know the owner isn't recording the conversation?
