They say they don't listen for watchwords and only record video on demand. Good.

But that means their hypothetical calorie-count example only works if you actively remember "I am eating, I should tell the pin to record my eating". Same with many other things; the wrist-worn smart devices are useful exactly because they are always recording, they are somewhat ambient.

I understand why they do it, I even applaud them for thinking about privacy, it might even be necessary (cough..Google glass...cough), but I feel they have to walk a tightrope between a rock and a hard place to bring privacy-consciousness and useful features together.

Yeah I was thinking on similar lines when it comes to food tracking. I did a study last year on how food consumption correlates with certain psychological features, but the lack of good data made the study very hard to do.

Self reported data is always annoyingly unreliable.

This product would probably be better than self reporting, but not good enough.

The privacy issue is annoying thing. If it was a on-device ai model things might be easier to accept. But I such a device is further in to the future.
