US Patent 10271774 Activity tracking device and associated display

An activity tracking system includes a sensor device and a display device. The sensor device is configured to be carried by the user and includes at least one sensor configured to obtain the activity data for the user. The display device includes a display screen. The display device is configured to receive the activity data obtained by the sensor device and display the activity data about a circular axis on the display screen. The circular axis is provided as a solitary closed loop circular axis with respect to a defined center point. The activity data includes first data on one side of the circular axis and mutually exclusive second data on an opposite side of the circular axis. The first data includes a first start time and a first end time, the first end time occurring in a selected day and the first start time occurring in a previous day. The second data overlaps the first data on the circular axis such that both the first data and the second data are associated with at least one point on the circular axis.
