Disclaimer: I'm not sure where to put this. It's not a programming question, but it is a technical question involving an interactive gadget, having to do with usability.

I've been trying to create a low power controller with an e-ink/e-paper display. Since they retain their image when the device is idle I can deep sleep the MCU and take just 10uA of power, waiting for a wakeup signal.

The trouble comes when you hit a button on the controller. I need to update a number you can increase or decrease by pressing the appropriate button. Even on my prototype device with super fast partial refresh the display updates terribly slowly relative to what is needed for this feature.

I'm not in a position where I can necessarily move away from e-paper. I am too far into the project and I don't have complete control over it anyway. There are e-paper displays, like those used for Nooks and Kindles that have virtually instant refresh rates but they are cost prohibitive for this application, and too large besides.

What I was thinking was I could give you an audible cue when you hit a button, and only update if you stop pressing the buttons for say, 2 seconds. That way you can rapidly click the numbers up and down. You won't get a visual cue right away, but at least you'll have audible feedback whenever you hit a button.

Does this seem too counterintuitive? Anyone have any other ideas?
To err is human. Fortune favors the monsters.
