Activity and Wellness Monitor  Favorite




An activity monitoring device is a highly integrated system composed of several modules. It used to collect, interpret and summarize data with the goal to improve health and fitness performance. These devices are non-invasive and worn on the body – band around the wrist, a clip on form factor for the belt or even as jewelry – and include capabilities such as pedometer, ECG (heart rate), data storage, wireless communication, timer, and a chronometer. Another key aspect of these wearable devices is the user interface which can range from simple button presses to touch screen.
