Saqib Shaikh, a blind developer at Microsoft, shows at Build 2017 how he writes and debugs code in Visual Studio using a screen reader. This version adds subtitles.

A video showing a virtual camera built in Blender that simulates lenses and film layers using path tracing, to make physically modeled photographs.

Tavis Rudd describes how RSI forced him to program by voice, and shows the Python and Emacs Lisp system he built with voice recognition. A live demo creates and deploys a small system without touching the keyboard.

Deviant Ollam and Howard Payne give an in-depth DEF CON 22 explanation of how elevators work, from the pit to the penthouse. It covers their control modes and how pen testers use elevators to bypass building security.

David MacKay's 2007 Google Tech Talk presents Dasher, a text-entry system driven by continuous gestures and a language model, reaching about 35 words per minute with one finger and 25 hands-free. It explains the information-theory reasoning behind the design.

Emily Shea, a Fastly engineer with repetitive strain injury, describes using voice dictation as her main way of programming. She covers homophones, custom vocabulary and building her own voice commands to write Perl.
