Hey, I’m working on a project to find the most comfortable resting position for my fingers on a flat surface, ultimately to position buttons ergonomically on an arcade-style game controller I’m building. So far I’ve tried photoshop sketch and various other iPad drawing apps, using a large brush with low opacity, to tap my fingers multiple times, resulting in a sort of heatmap of where my fingers prefer to rest. The problem with these apps is that they only accept input from one finger at a time, so I don’t trust my results just yet. Ideally, I want to do the same thing by tapping all five fingers at once. I’d be super grateful if anyone could point me in the direction of an app like this!
