Introduction to Lumo Lift [Video]


Now that we’ve announced our shipping schedule, we hope you’re excited to receive your Lumo Lift. We certainly can’t wait for you to start using it!

In the meantime, check out this short video to learn a bit more about Lumo Lift and how to use it. We promise, this info will come in handy when you get a package from us in the mailbox later this summer.

It’s Time to Take a Real Break!

We know you’ve seen it. You’ve probably done it, and we admit that we’re guilty too. Lunchtime rolls around, so you eat your salad at your desk while catching up on email. You take an afternoon coffee break, but spend the whole time on your phone, scrolling through Facebook or texting your friends. In our busy, plugged-in world, it’s easy to feel like we should always be doing something on our devices.

Turns out, all of that on-the-fly “productivity” is actually making us less productive. And what we actually need? Real, unplugged breaks. A University of Illinois study shows that our brains start to fatigue when we spend an extended amount of time focusing on a single task, but that our mental energy supply can be quickly replenished by diversions. Depending on the nature of your tasks, experts recommend taking a short break every 30 to 90 minutes. For example, take a quick stretch break after a 30 minute flurry of emails, but work on a big report in focused 90-minute chunks. No matter what, be sure to schedule breaks into your day!

Wow, the past month has been pretty busy here at LUMOback. We’ve been building a lot of neat things with the data we have. One of the ideas that we’ve been working on is an algorithm that trains LUMOback to be more vigilant about monitoring your posture during certain points of the day, while cutting you a bit more slack at other points. As a starting point for this project, I’ve been analyzing how people’s posture varies throughout the course of the day and identifying interesting patterns.

I’ve noticed that my friends and I often experience an “afternoon slump,” especially after a heavy lunch or an early morning. In most cases the slump goes away after a caffeinated pick-me-up, but I was interested in how this afternoon dip in energy affects posture. In order to explore this question, I evaluated a sample of our most active users between the ages of 26 and 65.


The sample consisted of roughly 200 users covering a 1 month span containing about 4900 hours of sitting time and 2100 hours of standing time. The average posture values were calculated on an hourly basis across all days and each day was weighted by the amount of data collected that day. The following figure maps out average good sitting and good standing posture per day hour by hour:



Just focusing on primary work hours (8am – 6pm), there’s a clear dip for the sample users aged 46-65 around 1pm-2pm but good posture peaks again right before the work day ends. The sample users aged 26-45 fare a little better throughout the day but sitting posture begins to gradually deteriorate around 3pm. Fortunately, standing posture is better and more consistent among both age groups in our sample.


In the future, I’ll break down the “afternoon slump” even more and maybe discover certain groups of people who avoid it altogether (or a group more susceptible to it). In these situations an adaptive LUMOback feature would be an advantage, buzzing more when people are more prone toward slouching.

Do you experience the afternoon slump? Are you above or below the average posture values? Do you like the idea of an adaptive LUMO buzz?
