One of my friends spotted the little metal square on my shoulder recently and asked “is that a Lumo? I returned mine.” Turns out it didn’t do what he had hoped it would, which was to provide constant feedback on his posture and correct it in every situation. It is not smart enough to do that.
I haven’t returned mine because it does do what I want it to do, which is a far more specific use case. My main problem is hunching when I work sitting at a computer. I sometimes work standing, but for tasks that require intense longer term concentration I usually sit. For that, the training sessions that Lumo does well are perfect. For a training session (15 minutes to two hours) you tell Lumo what your good posture in the specific static setting you are using is, and then it corrects you when you diverge from that. I have mine set at 15 minutes.
But other settings that are less static it does not do well at. For example I often hunch when dining out, a side effect of the fact that I am smaller than average and most chairs are too big for me and require a higher than average effort for me to stay in a decent posture since my feet don’t touch the floor. But Lumo does not do well here. If I set a training session it will correct me for doing things like drinking my drink or passing a dish to the person next to me.
Of course you could have it still be on measuring whether or not you are upright without correcting you, but that would require telling it your ideal posture by double pressing it every time you do something different. For me in a single average day that would mean setting it on the bus, when I get off the bus to walk the half a mile from the bus stop to work, sitting at my desk at work, standing at my desk at work, sitting at the table at lunch, sitting at my desk, standing at my desk, sitting at a meeting in a different chair, sitting on the train, sitting on the couch at home etc. etc. etc. This would be time-consuming and frankly I’d forget. That’s why one day I received an email from Lumo congratulating me for my great posture when in fact most of the day I’d be on the couch with terrible posture- because I had put it on while sitting at my table eating breakfast and then not set it at all when I moved to the couch.
The software is also not as user-friendly or as cross-platform as it could be, but at least they seem to be frequently improving it. I’d definitely recommend the Lumo Lift if you are like me, and spend large blocks (at least 15 minutes or more) in static positions at work.
