Embodiment Construction

[0027] figure 1 The placement of sensors relative to a subject's hand in a smart wearable device is shown. figure 1 It is only illustrative and not limiting. It can be understood that these sensors are arranged at the corresponding parts of the corresponding phalanx in the smart wearable device, so that when the object wears the smart wearable device, these sensors can be read from the corresponding phalanx Receive sensor signals for subsequent processing. Although the distribution of sensors is shown by taking the subject's hand and phalanges as an example, it does not exclude the distribution of sensors relative to other body parts such as the subject's legs, and data processing is performed based on the same principle and setting.

[0028] Such as figure 1 As shown, in order to accurately simulate the movement of each joint of the subject's hand, the sensors are preferably set on different phalanges connected by each joint, for example figure 1 Shown on phalanges 1-12. Fo...

Abstract

A data processing system and method for a intelligent wearable device is provided, the intelligent wearable device being worn by an object and comprising a plurality of groups of sensors, each group of sensors being disposed at a position on the intelligent wearable device corresponding to a different phalanx of the object for obtaining sensor data of the corresponding phalanx, the sensor data at least comprises acceleration data and angular velocity or angular acceleration data; the data processing system includes a first movement determination unit for determining, based on acceleration data of any one of a first phalanx and a second phalanx, whether the first phalanx and the second phalanx connected by a first joint move only in a plane parallel to a ground plane, respectively; and an angle determination unit for determining a joint angle at the first joint by the first phalanx and the second phalanx based on the angular velocity or angular acceleration data of the first phalanx and the second phalanx when it is determined that the arbitrary phalanx only moves in a plane parallel to the ground plane. In this way, the joint angle can be determined more accurately in a specific case.

Description

technical field [0001] The present invention relates to data processing, and in particular to data processing of sensor data from smart wearable devices. Background technique [0002] Smart wearable devices such as smart gloves have been developed and started to be applied in industrial or medical environments to monitor actions of wearers of the smart wearable devices. In an industrial environment, smart gloves can be used to monitor / analyze the operations of workers in factories to ensure that workers perform production operations in accordance with correct operating specifications, thereby improving production efficiency. In a medical setting, smart wearable devices can be used to monitor a patient's rehabilitation exercise to ensure that the patient is performing the appropriate exercise as prescribed by the doctor. [0003] A plurality of sensors are usually arranged in a smart wearable device to sense the motion of the wearer. In some cases, it is necessary to determ...
