Abstract: A method for determining posture-related information of a subject using the subject's image is provided. The method comprises: determining, from a first image, first positions of a first pair of joints and a first body segment length of a first body segment associated with the first pair of joints; determining, from a second image, second positions of a second pair of joints and a second body segment length of a second body segment associated with the second pair of joints; determining, based on an algorithm that reduces a difference between the first and second body segment lengths, whether the first and second pairs of joints correspond to a pair of joints; If the first and second pairs of joints are determined to correspond to a pair of joints, determining, based on the second positions, information of a posture of the subject; and providing an indication regarding the information.

Abstract: A method for monitoring postural and movement balance for fall prevent is provided. The method includes the following steps. Multiple sensing signals of a human body are obtained. A center of mass (COM) signal and a center of pressure (COP) signal are modeling according to the sensing signals. A correlation coefficient is calculated according to a mediolateral velocity of the COM signal and the COP signal. A threshold is obtained according to at least one regression model stored in a database. Whether the correlation coefficient is smaller than the threshold is determined. An alert is produced when the correlation coefficient is smaller than the threshold.

Abstract: An exercise machine includes a frame, a saddle, at least one crank arm, at least one pedal, a force measurement, an angle detector, a processor, and an adjustment mechanism. The saddle is connected to the frame. The crank arm is pivotally connected to the frame, and the pedal is pivotally connected to the crank arm. The force measurement measures a force applied to the crank arm, and the angle detector detects a crank arm angle. The processor is programmed to calculating a work value according to the force and the crank arm angle. The feedback mechanism returns the work value to a user.

Abstract: An ergonomic inertial positioning system comprises a motion sensor, an angle sensor, and a processor. The motion sensor detects movement of an object. The angle sensor detects angle variation of the heading of the object. The processor determines motion status of the object based on detected data provided by the motion sensor and the angle sensor, and calculates displacement of the object utilizing the detected angle variation thereof based on the motion status.

Abstract: Foot measurement and footwear manufacture systems and methods. A three-dimensional foot frame of a foot and pressure data corresponding to a bottom of the foot are measured, and a first and a second group of characteristic points are respectively determined accordingly. A preset foot skeleton template model is adjusted according to the second group of characteristic points, and merged into the three-dimensional foot frame according to the first group of characteristic points and protrusion points of the adjusted foot skeleton template model. The protrusion points and/or joint points of the adjusted foot skeleton template model are connected to generate at least one line and at least one plane, intersecting the three-dimensional foot frame at contact points and contact planes, respectively. The foot frame size is determined according to the distance between the contact points and the girth of the contact planes.

Abstract: A cardio-respiratory fitness evaluation method is disclosed. Personal data is obtained according to an input operation and a submaximal exercise test is performed according to the personal data and a selected exercise mode. Physical parameters are retrieved and analyzed to determine whether abnormal signs are detected and, if not, the physical parameters are recorded. It is then determined whether the submaximal exercise test has been completed, and, if not completed, another submaximal exercise test is performed, and if completed, an evaluation for cardio-respiratory fitness is performed to obtain evaluation results.
