Abstract

The invention relates to a man-machine interaction intelligent device based on sitting posture identification and application thereof. The device comprises a group of pressure sensors, a wireless transmitting-receiving module, a group of feedback devices, a control circuit, at least one battery and a microcontroller, wherein the group of pressure sensors at least have one pressure sensing function, the wireless transmitting-receiving module is used for wireless communication, the group of feedback devices are used for warning users at the right time, the control circuit responds to change of pressure of the pressure sensor and controls the startup or stop of the feedback devices; the at least one battery supplies power to the device, the microcontroller is connected with the pressure sensor group through the control circuit, and the microcontroller is connected with a PC (personal computer) through the wireless transmitting-receiving module. The application of the device comprises the following steps of: enabling the microcontroller to be in a monitoring mode, obtaining pressure distribution data, judging whether a user uses the device or not, if the user uses the device, entering into an operating mode so as to carry out sitting posture identification; otherwise, maintaining the monitoring mode and the like. Compared with the prior art, the device and the application provided by the invention have the advantages of high identification efficiency, lower cost, high practicability, wide scope of application and the like.

Description

technical field [0001] The invention relates to a human-computer interaction intelligent device and its application, in particular to a human-computer interaction intelligent device based on sitting posture recognition and its application. Background technique [0002] Sitting is a natural posture of the human body. Bad sitting posture will affect study and work status, and even endanger people's health. In the information age, the use of smart devices for sitting posture recognition will play an increasingly important role in people's study, work and life. Such as identifying the sitting posture status of students and office workers in the classroom and reminding them in due time, and for special groups of people, such as in the field of health care, collecting patient sitting posture data to assist medical analysis. [0003] After a literature search of the prior art, it was found that A Sensing Chair Using Pressure Distribution Sensors, IEEE / ASME TRANSACTIONS ON MECHATR...
