    Abstract: A method and a system for achieving a self-adaptive surround sound. The method comprises: recognizing specific positions of a room and a user in the room by using an object recognition technology, capturing focusing images of recognized objects by controlling a camera using a focusing control technology, and recording corresponding focusing parameters (S110); calculating position information of the room relative to the camera and position information of the user relative to the camera according to the images and the parameters (S120); calculating sound beams that can achieve the surround sound at the position of the user in said room according to aforesaid calculated position information of the room and the user (S130); obtaining parameters of a filter group according to the calculated sound beams, and adjusting the filter group of a loudspeaker array according to the parameters (S140); and playing an audio signal via the loudspeaker array after the audio signal is filtered by the filter group that has been adjusted according to the parameters to form surround sound at the position of the user in the room (S150).

    Abstract: The present invention provides a human body movement state monitoring method and device. The method comprises the following steps performed repeatedly: obtaining acceleration signals having a set sampling time period from output of a triaxial acceleration sensor worn on a human body, and calculating the energy and average power of the acceleration signals; determining a human body movement state according to the average power of the acceleration signals, and if the average power of the acceleration signals is more than a predetermined fierce movement threshold, determining that the human body is in a fierce movement state, if the average power of the acceleration signals is less than a predetermined sleeping threshold, determining that the human body is in a sleeping state, if the average power of the acceleration signals is less than the fierce movement threshold and is more than the sleeping threshold, determining that the human body is in a light movement state; if the human body is in the fierce movement state, further determining whether the acceleration signals have quasi-periodicity, if the acceleration signals do not have quasi-periodicity, determining that the human body is in an irregular fierce movement state, if the acceleration signals have quasi-periodicity, determining that the human body is in a regular fierce movement state. The method can automatically, comprehensively, round-the-clock, accurately monitor various movement states of a person.

    Abstract translation: 本发明提供一种人体运动状态监测方法及装置。 该方法包括重复执行的以下步骤:从佩戴在人体上的三轴加速度传感器的输出获得具有设定的采样时间段的加速度信号,并计算加速度信号的能量和平均功率; 根据加速度信号的平均功率确定人体运动状态,并且如果加速度信号的平均功率大于预定的剧烈运动阈值,则确定人体处于激烈的运动状态,如果平均功率 的加速度信号小于预定睡眠阈值,如果加速度信号的平均功率小于激活的移动阈值并且大于睡眠阈值,则确定人体处于睡眠状态,确定人体 身体处于轻微的运动状态; 如果人体处于激烈的运动状态,则进一步确定加速度信号是否具有准周期性,如果加速度信号不具有准周期性,则确定人体处于不规则的激烈运动状态,如果加速度信号 具有准周期性,确定人体处于正常的激烈运动状态。 该方法可以自动,全面,全天候,准确地监控人的各种运动状态。
