Mostly this is silly, props for making it just like the communicator from Star Trek TNG.

I can only think of one use case that would be awesome that I couldn’t get with an iPhone: automatic food tracking.

Having a camera mounted near your neck you could use computer vision/AI to track everything you eat and automatically tell you how many calories you’ve consumed for the day. This would be way better than manually logging food intake like we have to do now, and could be very helpful for losing weight or just staying healthy.
