Fitness Tracker Instructions

  

Anyone that knows me understands my commitment to presenting simple, easy and fun instructions. Well, the truth is I am still working on it.
 

Here is my suggestion in the interim:
Find a 10 year old to help you.
 

You will also be pleased to know what you can learn by simply playing with the VeryFitPro app… Just start pushing buttons. New Worlds will welcome your arrival. 


Below, I break down what makes The Navigator tic.


From the sensors to the algorithms, this is how The Navigator works her Magic

Simply speaking, The Navigator measures motion: It has an onboard 3-axis accelerometer to track movement in every direction and a gyroscope to measure orientation and rotation. 

The data collected is then converted into steps and activities and from there into calories and sleep quality. All of this information is collected and crunched to create an overall reading.

These sensors measure the acceleration, frequency, duration, intensity and patterns of your movement—taken together that's a good bunch of data and it can help the Navigator know if you're walking down the road or just waving at someone you know. 

Importance of GPS
The GPS receiver in the Navigator receives a high-frequency, low-power radio signal from a network of 29 total satellites orbiting the Earth. The time it takes for a signal to reach your wrist can be translated into your distance from the satellite, which is translated into precise coordinates. 

Unlike simple step counting, GPS allows runners, walkers, hikers and cyclists to easily map their exercise and analyze the terrain where they were exercising.

Getting in-depth

Heart Rate
The Navigator uses optical sensors to shine a light on your skin and measure your pulse through it. The light illuminates your capillaries, then a sensor measures the rate at which your blood is being pumped (and thus your heart rate).
Unlike the EKG a doctor might use to measure your heart rate, an optical heart-rate monitor measures your heart rate using light. An LED shines through the skin, and an optical sensor examines the light that bounces back. Since blood absorbs more light, fluctuations in light level can be translated into heart rate – a process called photoplethysmography.

Sleeping Patterns
Using a process called actigraphy, The Navigator translates wrist movements into sleep patterns. It's a useful guide, but it's not as accurate as polysomnography - this is what the experts use to measure sleep in a lab, and it monitors brain activity rather than how much you're tossing and turning.

Calories Burned
The human body is constantly expending calories just to stay alive. Breathing, thinking, sleeping and digesting your food all consume calories. Your basal metabolic rate (BMR) is the sum total of all the calories burned by your body just doing these fundamental tasks; it accounts for the vast majority of calories burned by your body.

The Navigator estimates your basal calories using a formula based on the Harris-Benedict equation, which includes your height, weight, gender and age. Your BMR is the number of calories you need to consume on a daily basis to maintain your weight. If you want to lose weight, you need to burn calories in excess of your BMR.  The calorie total that is recorded on your tracker is a calculation of the calories that you burn in addition to your BMR. In other words, it’s based on the tracker’s best calculation of how active you are beyond simply burning calories to run your body and perform the tasks of daily life.  

The Navigator calculates calorie burns for specific activities. For example, it applies a different formula to calculate calorie expenditure for cycling than it does for swimming or running. 

Add in the Algorithms
The VeryFitPro App is the final link in the chain, presenting your data in a user-friendly format once it's been passed through various algorithms and refined accordingly. You'll notice that your fitness tracking app comes with the ability to add data and exercise manually as well.
