Abstract

The invention discloses a data glove based on ultrasonic soft sensing, comprising: a glove body based on ultrasonic soft sensing; the soft sensing based on ultrasonic waves comprises an ultrasonic transmitter, a soft waveguide tube and an ultrasonic receiver. One end of the soft waveguide tube is connected with the ultrasonic transmitter, and the other end of the soft waveguide tube is connected with the ultrasonic receiver; when the glove body is bent, the length of the soft waveguide tube can be changed. And / or when the glove body grabs an object, the soft waveguide tube is pressed to change the cross sectional area of the soft waveguide tube. Due to the fact that the bending degree and / or the grabbing contact pressure are / is detected through deformation of the soft waveguide tube, external electromagnetic interference is avoided, and the detection accuracy is high. And the curvature and the grabbing contact pressure are respectively detected through the propagation time and the amplitude attenuation, are independent from each other and do not influence each other, so that the problem of low accuracy caused by a coupling phenomenon of the curvature and the grabbing contact pressure is avoided, and the detection accuracy is further improved.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a data glove based on ultrasonic soft body sensing. Background technique [0002] The data glove is a multi-mode virtual reality hardware. It uses the sensor embedded in the glove to detect hand movement signals. Through software programming, it can perform actions such as grasping and releasing objects in the virtual scene, and can also be used as a tool for controlling scene roaming. . [0003] In the existing technology, most of the existing data gloves are mainly based on inertial sensing, optical fiber sensing and electrical sensing. These sensors are either susceptible to external electromagnetic interference, resulting in low accuracy, or the manufacturing process is complicated and the cost is high. [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] The technical problem to be solved by the present invention ...
