Non-pointer input devices

[scd31]

Hello! I'm working on a small side project which involves a mobile-phone type device. It has a non-touch screen, a keyboard, and a joystick. I'd like to use the joystick to select different elements (i.e., not to move a pointer around), and use the keyboard for entering text in selected text boxes.

The readme says "Currently, only pointer input devices are supported" but I'm wondering if it would be feasible for me to hack something in. There don't seem to be many options for embedded guis in rust, so if not, I'd probably be rolling my own solution.

Thanks!
