I stop myself from slouching on long drives by adjusting the rearview mirror such that if I&#x27;m not sitting up straight, it won&#x27;t show the back window correctly.<p>I notice pretty quickly when I&#x27;m not seeing the full rear window anymore, and adjust my posture.<p>I&#x27;ve been wondering if a similar tactic might work for monitors -- e.g., the same tech that can make a monitor intentionally hard for someone next to you to read might also let you adjust it so that if you slump down a few inches, it&#x27;s hard to see.<p>Not sure of a similar tactic for public speaking (since nowadays you&#x27;re likely to have a mic on your lapel...) but it also works for recording; you adjust your posture how it ought to be for good voice production, adjust the mic with it, and then if you slump the mic is no longer in the right place.
