Generate sounds related to an environment that make the environment easier to use for people who might have issue with collecting data via sight or physical capabilities. This includes data they might not be able to perceive, say “how many people are in the elevator coming to my floor?” or “when will my bus arrive at my bus stop?”
Universal design and accessibility are good starting places. I work with a lot of heat when I’m in the studio, welding metal or working with glass. As we usually say (rather loudly) while going to the first-aid box, “hot metal looks just like cold metal” or “hot glass looks just like cold glass”. I have temperature probes but they require me using both hands while looking at a screen. How can I get an audible warning that I’m about to touch something dangerously hot?
