Boox Blue is a remote control pedal in the form of piano keys that allows musicians to operate an e-reader with their feet. When the pedal is pressed, the page on the Bluetooth-connected e-reader is turned. This is convenient when playing from written scores as the musician need not manually turn the page but rather can continue the performance fluently. This is of particular advantage in en­sembles as the interplay can take place in an undisturbed way. The pedal pres­ents itself in a piano key design, which is a successful allusion to the music and also considerably simplifies the operation of the device.
