NeurIPS (Dec 2019) had a 50-minute panel discussion on disabilities in AI and how the conference could best meet those needs. I have transcribed the discussion here:

Some suggestions include:

• having a ramp at all times for stage access, rather than waiting for a request
• considering well-being at conferences
• providing quieter and less crowded poster sessions
• considering invisible illnesses more
• considering cognitive disabilities
