Abstract

A method and an apparatus for integrating data from multiple wearable devices is provided. The method includes receiving, by a processor from a wearable device, physiological indicator data associated with a statistical item being collected for a user and a timestamp associated with the physiological indicator data, in which the statistical item is collected by the wearable device, and determining, for the user, fused physiological indicator data associated with the statistical item based on, for each of the multiple wearable devices, a priority level, the physiological indicator data, and the timestamp associated with the physiological indicator data, in which the multiple wearable devices comprise the wearable device and at least another wearable device associated with the user. The apparatus includes a processor and a memory. The memory is configured to store instructions which when executed by the processor become operational with the processor to implement the method.

First claim

What is claimed is:

1. 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.

selecting a target wearable device from the multiple wearable devices based on a priority level and a timestamp associated with the unsynchronized physiological indicator data collected from the target wearable device,
wherein the target wearable device is selected from the multiple wearable devices based on a highest priority level of the multiple wearable devices, when a difference between the timestamp associated with the target wearable device and the timestamp associated with another wearable device does not exceed a threshold.

6. The method of claim 5 , further comprising:
when the data is being integrated from the multiple wearable devices in the realtime synchronization mode, prior to determining the fused physiological indicator data using the unsynchronized physiological indicator data collected by the target wearable device, determining the fused physiological indicator data using the unsynchronized physiological indicator data collected by the target wearable device between the current timestamp and an earlier timestamp for which no synchronization has been performed.

7. The method of claim 5 , wherein determining the fused physiological indicator data by synchronizing the unsynchronized physiological indicator data according to the timestamps comprises:
when the target wearable device is detected to change from a first wearable device to a second wearable device, receiving historical physiological indicator data from the first wearable device and current physiological indicator data from the second wearable device; and
determining the fused physiological indicator data based on the historical physiological indicator data from the first wearable device and the current physiological indicator data from the second wearable device.
