Abstract

The invention discloses a user activity recognition method and a user activity recognition device. The user activity recognition method is used for an intelligent terminal with a sensor, and includes: obtaining first data of the sensor; calculating the first data according to a first algorithm so as to obtain a first activity recognition result; using an amending model built according to training data to amend the first activity recognition result, and obtaining a second activity recognition result, wherein the training data includes at least one group of user relevance information and history data, the history data comprises a user activity recognition result and a user activity of a user label corresponding to the user activity recognition result, and the user relevance information at least includes one item of obtaining time, an obtaining position, user personal information and application use state information of sensor data used to confirm the user activity recognition result; confirming the second activity recognition result as the user activity. The user activity recognition method improves recognition accuracy for the user activity.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a user activity recognition method and device. Background technique [0002] With the development of mobile communication, a variety of powerful sensor devices are integrated into the current smart mobile terminal, such as acceleration (Accelerometer), ambient light (Ambient Light), Global Positioning System (Global Positioning System, GPS), proximity sensor (Proximity Sensor), compass (compass), gyroscope (gyroscope), camera (Camera), etc., smart terminals can capture small changes in each sensor in real time and respond accordingly. [0003] The ubiquity of these sensors in mobile communication devices provides great application opportunities for data mining. Analyzing and mining sensor data in mobile terminals to identify user actions and activities is currently a popular subject, with great academic and commercial value. For example, use smart phones to dete...
