> I'm not sure my feet have the accuracy to work as a mouse.

You should be thinking more of like a trackpoint for your feet/foot.

> Foot mouse will unfortunately stay niche, but when I saw the device in this article, I thought, "Why not for everybody?"

I can feel my tongue having a muscle ache just by looking at this.

Demo showing cursor accuracy and voice control/talking when the MouthPad is in the mouth:

* Only tongue tracking: https://www.youtube.com/watch?v=gH-z1KnIthM&t=1s * Head tracking mode (& wink to Neuralink demos :P) : https://youtu.be/6TTIsE4GMEU?si=TbS07BdjUaZDSwx4

Regarding fatigue: We constantly use our tongues for talking and eating without feeling tired and so far, current users haven’t reported tongue fatigue issues.

I don't get the tongue idea either, any kind of device you'd put in would make it hard to talk and who wants to eat a battery? Plus the movement area is pretty tiny.

Accurate foot movements are just training I bet, just like with anything else. Arm amputees have shown again and again that it's just a matter of practice. Plus, were any of us really that proficient with a mouse when we first started? We take it for granted but we've been honing that for decades.

Looking at how that one works, it's just four load cells. That would be exceedingly simple to reproduce with a microcontroller that supports HID. I might actually try to make one.

You can try some rapid prototyping with microbit and this library below that has ble hid support
