more fitbit / sleep research

fitbit vs sleep cycle ,
1. The tracker is directly on you 2. They only make claims they can back up They want to make sure they can prove their claims, so they don’t try to deduce or diagnose from the data they collect.
Hmm, interesting because I've repeatedly had people tell me that data is interesting but only for a week before people get bored. What is key is making the data "actionable" or providing "suggestions" / expert recommendations.

It may related to casual versus serious user audiences:

There are probably two kinds of Fitbit customers. First, casual users: people who want to know more about what they do with their bodies, people who are curious about their health and the potential to use technology to keep closer tabs on how well they’re doing. [...]
The second group is serious users: people who are actively trying to change their personal health behaviors and want a way to measure those changes. [...]
So while I found Fitbit useful and delightful, it was only temporarily. But that’s okay. It’s a fantastic tool for self-analysis, to get to know your sleep patterns, your typical daily walking distance. Great information. But once you have that information, if you’re not engaged in a program to change those things, you’re done with Fitbit. I know everything Fitbit can tell me. Maybe I’ll try it again in six months or a year, to see if I’ve changed. I’m a casual user. [...]  immune to these everyday emergencies and accidents and inconveniences. Until they’re virtually invisible and forgettable, [...] personal informatic hardware as intrusive medical devices rather than as the ethereal, ambient data sources I think many people envision.
Compare this to:
However, I am looking forward to the devices that are sure to follow the Fitbit that could perhaps track the onset of illnesses like cancer, give early warning of the Flu, or provide other vital health information that would provide actionable insights in day to day life. I can just hear it talking to me: 

So that's where the advice comes from: people who heard our pitch (yea, I was part of an accelerator program over IAP... long story there...)

More on this.
Unsurprisingly, it hasn't moved me to make a dramatic shift in the way I live my life, but it has given me a benchmark of how active or inactive I am on a daily, weekly, and monthly basis. In other words, you can be a non-gym rat and still get a multitude of uses out of this, but it will always be more beneficial for highly active people. [...] his requires users sliding the Fitbit into the included cloth wrist wrap, then holding the Fibit's one button for a few seconds before going to bed, and then again when they wake up. I found this an easy habit to pick up and build into my normal routine
One week's worth of integrating into daily life. Will I still be holding out in a month? We'll see... I'm pretty fascinated by my sleep patterns / productivity / mental well-being, but maybe I'll learn all I need to know in a week and be done.

HUH. There's actually published research papers by completely independent researchers on Fitbit. I guess maybe I can narrow down the scope of my 2.671 project:
Movement toward a novel activity monitoring device pdf (or pubmed)
The web-based Fitbit, available at a markedly reduced price and with several convenience factors compared to standard actigraphy, may be an acceptable activity measurement instrument for use with normative populations. However, Fitbit has the same specificity limitations as actigraphy; both devices consistently misidentify wake as sleep and thus overestimate both sleep time and quality.  Use of the Fitbit will also require specific validation before it can be used to assess disordered populations and or different age groups
while retaining mobility, actigraphy offers reliable results with an accuracy that is close to those of polysomnography (above 90%)[4] [...]  employed in new drug clinical trials where sleep quality is seen as a good indicator of quality of life.
up vs fitbit
That last one is actually of tremendous interest. With both Sleep Cycle and the Zeo, which do the same thing with varying levels of accuracy, you have the issue of potentially waking your partner at an inopportune time. Since they both use sound, it’s really impossible to wake only one person [...] Sleep Cycle is, at this point, the only one I’m using every night. Though it is the least accurate of the three. It’s the easiest. [...]  the reason I’m not using my fitbit is that I managed to misplace it and then, once I found it, I couldn’t find the charger. So, I might still be using it if I could charge it…
The FitBit is maybe the smoothest / most mainstream QS device on the market  (2011)

fitbit intern environment = design osmosis T/F?

Fluffy design-wise this site has a list of awards, though lulwut:

Designed for urban women  
Technical (real?) design-wise


mmm... time to stack up on that msp430 and RF programming experience stuff. yay skills-driven concrete goals for things to learn

I took a look at my logs and seems to be fixed. Derr. Very sketchy.
Also I kind of object to " seeks to be a central resource for news about open source development on health hardware" I was expecting open source hardware but no, it's open source software libraries for (prolly all closed-source) hardware |
I was hired by WorryFreeLabs for their Fitbit client mobile design work.Prepared the Android application interface icons, wallpaper screens for presentation. Work never went into production due to undisclosed reasons.
Yea, apparently there's a large ecosystem difference between SF (iPhones rule) and MIT (Androids ftw)
