I had a overhead-ish camera on a stick, that flopped up from the laptop screen back, to point straight down at the keyboard. Alternately, a phone clip-on fish-eye lens was low-res but ok, iirc. Kludgy little mirrors were iffyer, but there's a commercial one for iPad I didn't try. Blur wise, perhaps it was 30 fps? I was mostly ok with 60 fps. Would have liked 4k resolution for markers and precision though. More problematic was integrating high-latency "wait for the camera frame and then for mediapipe" with low-latency "fast keypress response". Drove me towards replayable event streams, and thus custom apps. But I was using it for custom XR-ish apps anyway. Running high-res mediapipe etal on multiple cameras kept a thinkpad doorstop laptop warm even before starting XR. Keyboard feel got a bit toasted. But TFA doing gestures-only fixed-poses low-res single-camera is far lighter.
