Hand virtual-real interaction system

Abstract

The invention discloses a hand virtual-real interaction system in the technical field of virtual-real interaction, which comprises a data glove and an upper computer, and is characterized in that the data glove comprises a control system, a power supply system, a monitoring module, a communication module and a data acquisition module; the data captured by the hand data acquisition unit and the big and small arm attitude detection module is subjected to Kalman attitude fusion and data amplitude limiting jitter elimination through a control system of the data glove, and the obtained hand action data is transmitted to the upper computer through the communication module for data fusion analysis; according to the method, the current space coordinate and the motion direction are calculated, virtual modeling is conducted on the hand through 3DMax based on a unity 3D platform, texture mapping is conducted on the hand model on the premise that a certain number of grids is met, data visualization is achieved, and real-time visual feedback is provided for a user.

Description

technical field [0001] The invention relates to the technical field of virtual-real interaction, in particular to a hand virtual-real interaction system. Background technique [0002] As the most powerful human-computer interaction interface so far, virtual reality technology has been deeply developed and applied in various fields such as simulation training, medical rehabilitation, and manufacturing, among which the virtual-real interaction of the hand is particularly important. Among many virtual-real interaction systems, the virtual-real interaction of the hand is one of the indispensable interactive systems for virtual reality experience. The lack of the virtual-real interaction system of the hand will greatly weaken the interactive experience. The hand virtual-real interaction system designed by the present invention has broad application prospects. In the fields of entertainment and leisure, safety training, vocational education, etc., it can provide users with a more ...

Problems solved by technology

[0007] 2. In the measurement signal obtained by the sensor, some interference signals that have nothing to do with the measured object are often mixed in. These interference signals will accumulate over time and make the measurement error larger and larger.

[0008] 3. In the existing hand virtual-real interaction systems, most of them use optical equipment to locate the spatial position of the hand and map the action data to the virtual environment. However, this method is easily interfered by environmental factors and requires the establishment of a data base station. Undoubtedly increasing the interaction cost also affects the interaction experience

[0009] 4. As a data bridge between hardware equipment and program execution, the upper computer should not only have the functions of data transmission and real-time data display, but the existing upper computer functions are not complete

The traditional modeling method is easy to operate, but there is a big gap with the real palm. When the fingers are bent, the joint joints are prone to breakage
