Someone at Apple had to design the watch to detect certain hand motions and purposely ignore them. That's a thing that someone had to do, otherwise false positives would be embarrassingly pasted across the Internet for to be laughed at.
No, it’s all ML models. It is very unlikely that an ML model trained on wrist motions for walking and running would falsely report steps for… other activities.
One of the reasons I got rid of my apple watch is because it would congratulate me for successfuly completing my exercise for the day just from turning over on the sofa. It would also tell me how good I slept when I forgot to wear it to bed. So, at least for me, that ML doesn't work
I didn't give it up, but I did laugh one morning at 2:30AM, laying in bed, dozing off and getting startled by the watch telling me I've been sitting for awhile and it suggests I get up and move a bit.
Definitely weird, pretty sure that’s not what most people experience. But such is the statistical nature of ML; your particular movements on that particular sofa fooled it.
I'm a lefty through and through in my sixth decade going around the sun. Mousing with my left hand is weird. Like completely wrong. Even on a touchpad I tend to "mouse" with my right hand.
Some lefty's do. I use the mouse right handed and even hold a guitar right handed. Some things you just train yourself to conform to society with. Kind of a shame I'm not an artist because I can have an amazing setup with a drawing tablet, keyboard, and mouse that is all at my beck and call.
(and... that, with my off hand as well. No clue why. I guess I hold a screen with my dominant hand?).
Because it allows you to use your dominant hand to control it, and also your non-dominant hand is more often free than your dominant hand, so it's free to swing around when you walk and better count your steps.
A good point.
Going into a supermarket I know I'll be filmed, but will avoid self-checkouts where I'm shown a live video of my exciting checkout experience as it does make it feel a lot creepier.
I’d wager most people take their phones in into the bathroom with them and use them on the toilet. I’ve even seen people on video calls in public restrooms!
I honestly don’t think the general public is all that concerned.
