Another use case I can think of would be, download onto the ring those contact details you agree to share with anyone you fist bump or shake hands with who also wears a smart ring.  That’s an easy win versus tapping phones together.  

And here’s another: use your thumb to tap or swipe the inside of your ring finger.  Try it, it’s easy, doesn’t require much movement and is discreet.  With Vision Pro or even an iPad or MacBook these actions could represent taps and swipes, for selecting and scrolling or other context-specific actions, such as the already mentioned control of a PowerPoint-type presentation or changing volume or muting of AirPods.  

A smart ring could also carry medical information; useful for those who don’t wear a smart watch or medic alert bracelet.  It could also contain reminders for taking medications, using a Taptic alert to send you to a notification on your phone.   Along these same lines it could handle fall detection either in lieu of wearing an Apple Watch or in conjunction with the watch to make a more accurate determination.  

A smart ring could count steps, and potentially gather other exercise data.  It could provide a secondary point of information gathering in this respect as it might be worn on the opposite hand versus the wrist the watch is worn on.  This could be useful for tracking certain types of movements associated with gym workouts, like weight lifting.  

Probably a few more use cases if I think longer.
