[0056] figure 2 As shown, the implementation process of jitter state detection is as follows:
[0057] Step (1). Definition of shaking state modes: static state, slight shaking, severe shaking.
[0058] Step (1.1). Find a series of testers who meet the test requirements, including juveniles (7 years old to 17 years old), young people (18 years old to 40 years old), middle-aged people (41 years old to 65 years old), elderly people (after 66 years old) ) each with 3 digits.
[0059] Step (1.2). It is required to hold the mobile terminal device and conduct a jitter test that lasts for one minute. At the beginning, the jitter is 10 times per minute, and then each test is increased by 10 times per minute until it is increased to 100 times per minute. A 5-minute break was set between tests.
[0060] Step (1.3). According to the feedback from the testers of different age groups, count the number of shakes that the testers feel tired during the test, and take the average value as ...

The invention discloses a motion state detection of a user mobile terminal in a mobile video playing process, and belongs to the technical field of the user motion state detection, and is realized ina user motion state acquisition system commonly composed of a terminal, a base station and a server. The method is characterized by comprising the following steps: establishing a video playing speed level adjusting module in the terminal besides establishing a collection, handling and storage module of acceleration and GPS data, adjusting the frame-breaking phenomenon produced by the jittering ofthe terminal; further establishing a mobile video playing fault alarming module, establishing the communication contact between the base station and a user, thereby acquiring the service experience and solution on the fault by the user. The lagging phenomenon is solved by arranging a mobile video fault signal processing module in the base station; the user authentication, application request legality affirmation and designated user motion state tracking module is arranged in the server so as to monitor the motion trajectory of a designated user terminal in the video playing process. The motionstate detection method disclosed by the invention simultaneously satisfies the demands of tracking special user trajectory by the terminal user and the related department.
Description
technical field [0001] The present invention relates to the field of motion state detection, in particular to a method for detecting the motion state of a mobile terminal during mobile video playback. In the present invention, according to the mobile terminal, in the process of playing video, the collected accelerometer data and GPS (Global Positioning System, Global Positioning System) data are used to detect and estimate the motion state (including shaking state and speed) of the mobile terminal using a statistical method. State), and then provide a scientific basis for identifying the user's motion state of a handheld mobile terminal. Background technique [0002] According to the latest industry analysis report of China Industry Information Network in 2017, as of December 2016: (1) the proportion of Chinese netizens using mobile terminals to access the Internet has risen to 95.1%; (3) In 2016, the per capita online time of Chinese netizens was 26.4 hours per week; (4) T...
