The tablet glove would be a fabric cover the attaches to the bottom of the tables, like a fitted sheet, and has a place to slip your hand into. Like a fingerless glove.
It would attach securely so you can put your arm along side of your body, and still have the tablet glove on your hand.
It would allow you to rest your arm while doing something with your other hand. Like couting inventory, or talking to a nurse.
The same thing for clipboards.
