I want to use some my Android device while walking. It is too dangerous to walk while looking at the screen, so I have modified the software I use so that it speaks and beeps so I know what is happening without looking at the screen.
It is still troublesome and dangerous to hold the device and use the touchscreen while walking. I'd rather place the phone in my backpack and hold some very simple controller in my hand.
- Wires or wireless are both okay.
- I don't need many buttons. Just 2-4 buttons is enough.
Is there any controller device which can plug into an Android device so that I can hold just the small controller while walking?
