Design and implement of a kind of virtual keyboard based on microcomputer and CMOS camera

The standardized keyboard is difficult for people with disabilities to use, and the bacteria which lives in the keyboard are not suitable for medical environments. To solve this problem, we give a new insight into the characteristics of CMOS camera and microcomputer, and use them to improve a kind of customizable keyboard based on some prior accomplishments. In this paper, dominate features and expected applications of CMOS camera will be presented. This kind of customizable virtual keyboard will be widespread in medical environment, transportation, and future computers.
