Activity, Health, and Nutrition Tracking and Monitoring Technologies


There’s been a lot in the news lately about technologies available now or in the near future that will help track your activity, nutritional intake, and vitals. The most recent and interesting of these are systems that scan your body, food, or beverages using spectrometers and similar technologies to provide accurate non-invasive reporting with little or no user involvement. This page offers a directory of the more prominent devices.

Activity Tracking Devices

There are a variety of bracelets and clip-on devices designed to track activity. Products like Basis monitor skin temperature and preparation to more precisely determine activity and calories burned. Here’s a short list of the products out there:

Food & Beverage Scanning Devices

  • GE Universal Food Scanner – Will scan a plate of food and tell you the calories.
  • Vessyl – Will scan beverages and can tell you what the beverage is, and in many cases who the manufacturer is, along with nutritional data.

Body Scanning Devices

  • AIRO – Uses spectrometer technology to monitor your blood and tell you what you’re eating based on blood analysis.



FitBit Sleep Quality Monitoring – Logging Sleep the Next Day


Summary. If you forget to start the “I’m going to sleep now” mode of the FitBit app on your iPhone, you can enter the sleep time the following day:

  1. Go to More
  2. Choose Sleep
  3. From the sleep screen, press + to add a new sleep session

FitBit will suggest a time that you fell asleep based on when your last activity was the night before. It assumes lots of activity leading up to no activity is the point when you fell asleep.

Determining Wake Time. The FitBit app will assume the current time is your wake time. If you’ve not thought to enter your sleep session until an hour into your day, you may have trouble remembering exactly when you woke up if you didn’t note it at the time. You can create the sleep session and then adjust it online at FitBit.com under the Sleep heading in your Log page. You’ll probably see a normal night of sleeping with a lot of activity toward the end. That’s when you were awake in the morning and walking around. You can trim back the wake time to the point that you first noticed activity in the morning. This will give you a fairly accurate record of your sleep session for the previous night.
