I would honestly probably use this if it were something like a tiny, unobtrusive, nearly-flat adhesive which I could stick to my hand or arm. Tie it in with some subtle bone-conduction headphones and I'd probably use it while outdoors. For example, it'd be awesome if it could do, say, or play certain things based on a sequence of taps which I can configure, like with Alexa Routines; saying "Alexa, resume podcast" out loud in public is a no-go. Make it thought-controlled and I'd use it without a doubt. I suspect this is just a kludgy initial version of some future thing that could eventually become really popular.
