Dong Wu, Jianhua Gong, Yi Li · 2018
Enhance Virtual Reality is an innovative technique to perform dynamic 3D visualization and emergency management based on sand table, which needs convenient human-computer interaction techniques. Traditional interaction techniques such as mouse and keyboard cannot realize convenient interaction between human and the dynamic virtual scene of sand table. Gesture interaction method has received increasing attention in human-computer interaction. This paper researches interaction techniques based on computer vision and deep learning, and convolutional neural network was used in gesture recognition. A prototype system based on 3D printing sand table is proposed to achieve dynamic scene demonstration. The experiment shows that gesture recognition accuracy is 99.51%, and the visualization system can perform convenient operations on 3D printing sand table.
