Doesn’t mention the most prominent one: coordinated activity measured on two wrist accelerometer devices in proximity is a decent-confidence indicator of sexual

What about basketball or run together? Unless you can get a measurement of extreme proximity

  They could also be wrestling, e.g., brothers and sisters. So as with all sensing data: context is critical to interpreting the data.

  "Grand-inquisitor I am not-guilty of the capital crime of adultery defiling the will of god. My explanation is that I met Ms Nin at the motel in question at lunch time to play basketball and go for a run." We hope our world will continue to change incrementally rather than sharply and suddenly. History tells us that all periods of incremental change come to an end. We continue to be setting up the tech for the future so there exists a turn-key surveillance system the stasi could only dream of. It doesn't matter so much just now, we think. Just like having no insurance usually doesn't matter when you make that decision. It seems really risky to me.

  when this sort of data can distinguish between walking normally and walking drunk, identify the sex of the wearer, whether they're carrying heavy objects, etc, yes, it can distinguish between playing basketball, running, and sex. this data can be 9D (accelerometer/gyroscope/compass), it's much finer-grained than "moving a bunch or not", and it wouldn't even take those kinds of movement analyses to differentiate between "horizontal, active, and highly correlated with person B (estimate: sex)" and "vertical, active, highly correlated with person B (estimate: dancing)"

  The accelerometer patterns and activity duration are very different for basketball vs sex.

  Do you usually run in sync with others?

Or simultaneous zero. Both took watches off.

  I took my watch off some 30 years ago. I wonder if my phone accelerometer is sending data to some company. I'm pretty careful about which apps I install and I logout from everything (not Google Play of course) and yet I don't trust every single app on my phone (banks, there is little I can do) or Google.
