摘要： 随着时代的发展，人们开始注重键盘的人性化设计，于是想到用光投影一键影，手敲击虚拟键盘光影，红外线摄像系统探测到模拟红外线敲击键信号。该文基于低温红外线探测技术和图像分析技术，提出红外虚拟键盘构想。阐述了在任何平面形成全尺寸虚拟投影普通键盘和手写键盘的技术设计和工作原理。

Abstract: Along with the ages development, people start make a point of the humanization design of the keyboard. Hence thought of to use up to cast a keyboard shadow , and the infrared ray camera system to probe into the emulation infrared ray to pound the key signal as the hands move. In this paper, according to the low temperature infrared ray probe into the technique to resemble with diagram to analyze the technique, and bring up the speculation of red and outside conjecture keyboard. A full-size conjecture to cast shadow the common keyboard to design with the technique of the handwritten keyboard with work in any flat surface principle is proposed.
