How does my wearable technology know what I am doing when I am doing it?
An activity tracker, also known as an exercise monitor is a small, portable Bluetooth device used to keep track of workouts and daily calorie intake. Some activity monitor products will collect information about your sleeping habits. If your sleeping habits are not up to par with other people in your age group, tracker products will help you achieve a better good night sleep.
What can an activity monitor do?
- Measure heart rate
- Track sleep patters
- Measure the distance of a morning run
- Time a workout
- Show calorie consumption and the amount of calories burned in a day
How does an activity tracker work?
Each tracker is made with a small sensor that can detect up and down, side to side, and forwards and backward arm movements. An activity monitor should be worn as soon as it arrives, and is activated. Certain monitors will turn themselves off after a week or so of inactivity.
The data collected from workouts and sleep will be sent over to your smartphone via Bluetooth to be viewed as an image or chart.
How does the heart rate monitor work?
Activity trackers often use photoplethysmography (PPG) to capture useful heart rate data. The PPG sensors also used in hospital settings, look at the amount of red under your skin. When the body is active, the heart pumps more blood, thus the more red and green seen by the sensor.
How does my Fitness tracker know when I am sleeping?
Sleep monitor technology in fitness trackers continues to get better, but the accuracy is not where it should be. Sleep duration is very hard to track because the algorithms built into fitness trackers are focused more on capturing heart rate and body movement. The tracker will use some personal data inputted into the smartphone application by the user (weight, age, height, etc.), combined with heart rate data and movement, to help it guess when you have fallen asleep. The good news is that most companies have given users the option to edit their recorded sleep time in case it is far from accurate.
Humans sleep in ninety-minute cycles. The first cycle is the lightest. The body will shift into different positions until it finds the most comfortable position, before moving into the deep sleep phases. Fitness tracker technology will likely understand the non-REM sleep period.

What is the Fitbit activity tracker?
The Fitbit is a wireless piece of wearable technology created to collect data on sleep patterns, the number of steps taken in a given day (or week), and the amount calories burned. The pedometer embedded into the tracker gives the most accurate step information. This brand of trackers pairs with an application on your smartphone. Owners of this device can open up the app to find several different charts and numbers comparing lifestyle data from week to week.
