Embodiment Construction
[0014] The wearable system proposed by the present invention for capturing the movement information of the upper limbs of the human body, the flow chart is as follows figure 1 shown, including:
[0015] Multiple sensors 1 are used to collect the three-dimensional angular velocity, three-dimensional acceleration and three-dimensional magnetic vector of each joint of the upper limbs of the human body, including arm sensors, palm sensors and finger sensors. The arm sensors and palm sensors are connected in series and worn on the arms and palms. The sensors are divided into five groups, and the sensors in each group are connected in series and worn on the joints of the five fingers respectively; in one embodiment of the present invention, a total of 18 sensor modules are used, of which 5 strings are respectively worn on the joints of the five fingers. For each joint, a string is worn on the palm, forearm and upper arm, such as figure 2 , and the collected three-dimensional angul...

The invention relates to a wearable system for capturing movement information of human upper limbs, and belongs to the technical field of human-computer interaction equipment. The wearable system includes sensors for collecting the three-dimensional angular velocity, three-dimensional acceleration and three-dimensional magnetic vector of each joint of the upper limb of the human body, used to receive the three-dimensional angular velocity, acceleration and magnetic vector of each joint of the upper limb of the human body, and calculate the real-time The central processor of the posture, speed and position of each finger joint, palm and arm is used to receive the posture, speed and position of each finger joint, palm and arm by sending the posture, speed and position of each finger joint, palm and arm to the wireless transmission module of the display , and drive the display of the human upper limb simulation model in real time. The wearable system has strong adaptability and is easy to wear. It can capture the movement information of the arm, palm and each finger in real time, completely and quickly, and can transmit and display it visually over a long distance. It can be applied to human-computer interaction, remote operation, and upper limb rehabilitation monitoring. and other fields.
Description
technical field [0001] The invention relates to a wearable system for capturing movement information of human upper limbs, and belongs to the technical field of human-computer interaction equipment. Background technique [0002] In recent years, human-computer interaction technology has developed rapidly. It mainly recognizes various human behaviors and body postures through related equipment to interact with the computer virtual environment to realize functions such as games, operation training, and fitness. Capturing human motion is key. At present, most human motion capture technologies are based on image recognition technology, which requires external devices such as cameras, and is easily affected by lighting, environmental conditions and other conditions. Contents of the invention [0003] The purpose of the present invention is to propose a wearable system for capturing the movement information of the upper limbs of the human body, so as to capture the movement inf...
