For our Hands-On Data Communication Project, we've chosen to investigate the Fitbit Flex, which is an activity tracker that can be worn on the wrist to track one's activities and sleep throughout the day. We experimented by using two subjects, who wore the Fitbit for a week each, so that we can compare the data. Our goal is to measure the accuracy of the device. We've found that there were a number of changes that could be done to our experiment to get more reliable and valid results. In conclusion, we have some suggestions on what could make the device better.
Introduction.
For this experiment, we've decided to test the Fitbit flex. The Fitbit is an activity monitor that can easily be worn on the wrist to track activities throughout the day, as well as sleep quality at night. The Fitbit uses Bluetooth Low Energy connectivity to sync data between the device and the device receiving the data, which could be a smartphone or a USB dongle that's plugged into the computer. The device will automatically sync data when the app is opened with 20 feet of the device itself. The Fitbit uses a built-in accelerometer to measure movements. We chose to experiment on this device because these activity sensors are very popular right now. It can be used to keep track of activities to help with weight loss or keep track of health conditions. It could be potentially used in healthcare settings to ensure patients adhere to their doctor's recommendations. It can also be used in the workplace to ensure employees are actively working. If the device accurately one's activities, it would be very effective in many aspects of life.
Methodology.
Our study involves measuring the accuracy of the Fitbit. In order to do so, we wanted to compare data between two subjects, so that we can compare the data because how one person moves throughout the day will be different from how another person moves. Because we did not have two devices, we decided it was best to each wear the device for one week.
