ThinkPad P53 "portable workstation" with DIY cameras on sticks mounted on back of screen. Here mostly a keyboard-cam that flopped up-and-over to look down on the keyboard, and a convex mirror bar along the base of screen for crappy touch detection. But also fisheyes hinged up to corners. Python/MediaPipe/libev under an Electron/browser stack.

Ah, so the laptop is normal and you've tacked on a DIY rig so it can see your keyboard. Is there a writeup/blogpost/repo somewhere? That's an interesting idea

  Nod. Sigh, regrettably not. A photo[1] got snagged for a twitter conversation, but little else. A different part of the effort, diy shutter glasses, got a brief reddit post. Failure mode: Big scope, "these kludges only matter if they end up day-to-day usable", "just for me - user community potential is zero". Motivated with an local in-person tech community ended by covid - I didn't even do a "ok, this looks dead, so let's scavenge a wrap-up". Ah well. I've been wondering what to do differently with a new potential project. Maybe try an offline live-blogging-flavored research journal, with a story of "when things comes up in conversation, I'll scavenging together a live-blogging-effort-level post in answer"? Thanks for the interest. Happy to answer questions. Hand/head/gaze/stylus tracking, electron-based tall stack (low-level-input to full-screen, X11 apps via screen capture - eg emacs presenting adjacent slightly different buffers for stereo), shallow-3D ui, integration with shutter glasses / nreal / diy-passthrough-ar-in-vr/drone-headsets, laptop keyboard as multitouch surface. And none of it usable. Lots of extra "well, that didn't work out" and "interesting, but no" spikes. Lots of "this only becomes usable if/when this other thing really works" dependencies. Blech. Might be able to pull out something bite-sized for a student thesis project or such. :/ [1] https://imgur.com/a/Z1VipaL https://imgur.com/a/Z1VipaL
