> frame rate, encoder quality. Especially low end phones do not have enough power to encode highly variable input (see previous bullet), resulting in unreadable images. An encoder setting for low frame rate (e.g. 1-2FPS) and high quality would be invaluable for such an use case.

Ways to go even better:

- Don't use an "<x>FPS" based model of continuous transmission - the paper isn't always updating by default

- In extremely low-bandwidth situations, never update while there's a hand in the frame; only update once the paper image settles again

- Get all fancy with feature detection and draw buttons on the corner of the paper; one of these could be "update" and the device would beep to acknowledge the frame had changed. This is actually practical as not everyone has bluetooth keyboards, audio-based commands would be distracting, and tapping onscreen buttons would nudge the device

- Perform frame border analysis and automatically crop and rotate the actual paper as it's moved around
