But even the most sophisticated and accurate exercise monitoring provides insight into a very small picture of our overall wellness. To provide greater insight into our quantified health, far more needs to be considered.
For the common problem of obesity, changing eating habits is likely to have a bigger payoff than the daily difference of a few thousand steps. And while there are many apps that allow people to input their food manually or even take photos of it, that is almost the equivalent of having us manually count the number of steps we take in a day.
Some of the earliest efforts in this space have come from the HAPIfork. It measures the speed and frequency with which one shovels food into one's mouth, but it can't distinguish between lettuce and butter-infused mashed potatoes. Then there's TellSpec, a spectrometer that offers to analyze the nutrient and allergen content of your food. Given, that's an order taller than a stack of Big Macs, and it's been met with a large dose of skepticism.
Stress, and how one deals with it, can be a key factor in determining one's level of wellness. It's easy to detect the signs of stress such as a faster heartbeat, and many gadgets like the Basis watch can measure that. What's more difficult is determining stress itself. Perhaps some guesses could be made about factors such as noise levels, late hours and scheduling. Companies such as Helicor, with its StressEraser, and HeartMath have developed biofeedback devices to help with relaxation and stress reduction; the latter has released a version that connects to iPhones via cable.
At CES, a couple of companies showed off app-connected air quality monitors. These included the centralized Alima air quality monitor and the tiny, distributed CubeSensors that won the TechCrunch Hardware Battlefield competition. Both do for indoor air quality what The Weather Channel reports on in terms of outdoor air quality.
The next Switched On will discuss some of the less volatile factors that have an impact on our health and wrap up with some thoughts on how we all might benefit if we can find a way for them to come together intelligently.
