I had a wired remote on my B&N Nook Glows.
Those devices had a connector for root console over UART.
A little microcontroller spit out a command to an injector daemon when you hit a button.
I got tired of fighting with the cord and the bed covers.
Unfortunately, those earlier models had no Bluetooth.
