USB Remote control switches come in all shapes and sizes. The most useful, I have found are single foot controlled switch (FS1-P) and triple foot controlled switch (FS3-P). Both are commercially available from China on Amazon. Prices range widely. Fair price for the single switch is 7-12 USD. Fair price for triple switch is 17-30 USD. The single switch can be used to accommodate persons without hands, persons with tremors and other severe neurological motor control issues. Player is operated by programming the Play/Stop button to be activated by foot switch. Leaving the player powered on and plugged in, persons can start and stop reading activities with single switch. Triple switch allows DA1 navigation and play by programming menu, previous and next buttons. Holding menu key down also allows bookshelf feature activization. Play/Stop button may be substituted for programming menu key if desired. This limits navigation to first DAISY level. Xbox controls work well and can offer remote control with dongle. Joystick controls with flight control hardware. Atari styled joysticks, from experience, do not seem to work. Remote USB Num pads can control all buttons of the players except power button.
