FitPath is a mobile application designed for Android devices. FitPath
connects with 3rd party sensors - specifically BodyMedia's bluetooth
armband and a wireless scale made by Withings and integrates that data
to help users manage their physical activity and fitness goals.
This app was created in collaboration with the
Quality of Life Technology
at Carnegie Mellon and with two faculty mentors:
Dr. Dan Siewiorek
and Dr. Asim Smailagic
Lead Developer and Designer
The FitPath app is designed to integrate with external sensors that have
collected health and fitness data about the user. This diagram illustrates
how the data collected by these sensors is captured and integrated into the
The BodyMedia armband is used to record the number of steps taken by the
user. It also collects data about physical activity data throughout the
day and sleep habits. This data can be transmitted to the BodyMedia servers
via USB cable or Bluetooth and is then accessed through BodyMedia's API.
The WiThings scale records a user's weight and transmits it wirelessly to
Withing's servers, which can be accessed through their API. The scale can
be configured to track multiple users.
Finally, the eWatch is designed to count the number of bites a user takes
while eating, giving the wearer a rough estimate of the number of calories
they've consumed. Users can use the FitPath app to record this data. This
watch was developed by the Quality of Life Technology Center and researchers
at the center are currently developing the algorithms used to sense the
number of bites taken by the user.
