The Control Center is a PC application developed by TI to interface with the Chronos. It has several different tabs, each of which highlight features of the Chronos. Shown here is what it looks like when the accelerometer data is being transmitted to a computer. From this tab the user can also turn on mouse control and wirelessly control the mouse buttons or the motion of the Chronos. This same GUI can be used to sync the time to the watch, calibrate altitude and temperature sensors, map the Chronos buttons to corresponding PC keys, simulate a heart rate monitor and perform wireless firmware updates. In addition this application is completely open-source, so it can be modified to fit specific user applications.
