This is an important question for me to be able to answer, because if I can’t convince you it’s worth splitting your time between alt input (like voice and eye tracking) and keyboard/mouse, I can’t reduce your chance of developing RSI. There’s the fear approach (I personally believe >50% of people who use computers full-time will develop at least minor hand injuries), but I don’t think fear is enough on its own. The most promising thing I think is workflow improvements. For voice, the ability to issue commands like “next song” while typing feels amazing. You can also be more specific about many commands, like “focus chrome” is nicer than mashing cmd-tab a bunch or binding a key to each app. For eye tracking, I think autoscrolling text as you read and jumping your mouse to the right spot when you look at your second monitor are two big ones.
