Jennifer, having the glasses themselves make sound would be hard. Easier to attach a small BT clip to the glasses that would sense when the glasses were removed and/or tilted to extreme, then trigger a linked app on the paired phone that would respond as pre-programmed (play a sound, show an alert, cue an episode on Netflix, whatever). Also would be useful for finding lost glasses or alerting when the glasses get too far away.
Anyway… thanks for the mention! Appreciated, especially seeing as how I’ve been lax on my Medium posting lately. [My wife is home!!! We have morning snuggles and daily commutes and meals together and snuggles every night and catching up on shows that is NOT binge-watching because 8 episodes in four days is less than 3/day (ergo!) and coming home together with hugs and kisses and I haven’t gotten back on Medium as much lately is what I’m trying to get across. Verstehst du?]
