Abstract

The invention relates to a sensor-based device and a sensor-based method for recognizing motion of a mobile terminal. The method comprises the following steps of collecting at least two acceleration data and magnetic field data, and performing noise filtering on the acceleration data; determining a usage state according to the current running state of the mobile terminal; determining the motion type of the mobile terminal by utilizing a secondary classifier unit according to the magnetic field data and the at least two noise-filtered acceleration data; determining motion information by utilizing a heat consumption computing element according to the motion type and the usage state of the mobile terminal, and moreover, converting the motion information into corresponding calorie consumption; reducing power consumption when the motion of the mobile terminal is recognized by utilizing a power optimization unit according to the motion type and the usage state of the mobile terminal.

Description

technical field [0001] The present invention relates to the fields of motion recognition technology and pattern recognition technology, and more particularly, to a sensor-based mobile terminal motion recognition device and method. Background technique [0002] In daily life, people have more and more requirements for sports-related information technology. Motion recognition technology can be used to identify the user's motion state. Currently, for motion recognition, some existing applications, such as ActiGraph and Polar Activity Watch, can perform motion recognition. However, in order to obtain the user's motion data, they all require an additional data collection component, which is very inconvenient for ordinary users. [0003] In the early development of motion recognition technology, Ling Bao et al. introduced a wearable suit with sensors in "Activity Recognition from User-Annotated Acceleration Data" published in Pervasive Computing 2004, which can recognize simple ...
