摘要
论文以3D全息投射技术为技术基础,实现键盘的虚拟化,以取代传统物理键盘,提高其使用寿命和安全性。虚拟键盘以激光为投射光源,以3D全息投射技术为技术支撑,通过三角测距原理对键盘按键动作进行捕捉,实现虚拟键盘与计算机的交互应用。
Taking the 3 D holographic projection technology as the supporting technology, the virtualization of keyboards is realized, which can replace the traditional physical keyboard, and improve its service life and security. The virtual keyboard takes the laser as the projection light source and the 3 D holographic projection technology as the supporting technology, through the principle of triangular ranging, the keyboard keystrokes are captured, so as to realize the interactive application of virtual keyboard and computer.
