Data statistics for wearable device

A method of using a client terminal of a user for integrating data from multiple wearable devices worn by the user, the method comprising:

• collecting, at the client terminal, unsynchronized physiological indicator data and a timestamp representative of a time at which the unsynchronized physiological indicator data was recorded from each wearable device of the multiple wearable devices, wherein each unsynchronized physiological indicator data represents a statistical item for the user, and wherein at least one of the timestamps is collected from a wearable device having a clock cycle which differs from a clock cycle of the client terminal;
• determining, at the client terminal, fused physiological indicator data representing a shared measurement of the statistical item among each wearable device of the multiple wearable devices by:
• identifying a synchronization mode to use to synchronize the unsynchronized physiological indicator data;
• and
• determining, based on the synchronization mode, the fused physiological indicator data by synchronizing, into a synchronized data storage format, the unsynchronized physiological indicator data according to the timestamps,
• wherein when the synchronization mode is a non-realtime synchronization mode, determining the fused physiological indicator data includes using a reverse chronological order for the unsynchronized physiological indicator data collected between a current timestamp and an earlier timestamp for which no synchronization has been performed, and
• wherein when the synchronization mode is a realtime synchronization mode, determining the fused physiological indicator data includes using a chronological order for the unsynchronized physiological indicator data;
• and
• outputting, at the client terminal, the fused physiological indicator data to a display of the client terminal to visually represent the synchronization of the unsynchronized physiological indicator data collected from the multiple wearable devices.
