摘要：

I.INTRODUCTIONKinect simultaneously captures depth and color informat ion and provides real-time, reliable 3Dfu ll-body human-pose reconstruction that essentially turns the human body into a controller.1Kinect has opened a new era for more advanced and natural Hu man-Co mputer Interface (HCI), and many exciting applications, fro m gaming to the medical field, have been developed. In this paper, we present a finger writing system that recognizes characters written in the air without the need for an extra handheld device. This application would allo w for brand- new Natural User Interaction (NUI) experiences, especially for remote applications. It is believed that Human-Co mputer Interface is becoming increasingly similar to the interaction among people. A traditional method to communicate with mach ines is by keyboard and mouse. In recent years, mo re advanced remote controller's suchas the Nintendo Wii remote and touch screens have been widely used and enjoyed by users. However, a handheld device is still needed. We propose using a hand to write in the air by treating the finger tip as a virtual pen. Using Kinect system, users gives input characters by moving their hands, enjoying a full-body-controlled experience. The remote input could enable several real-world services such as remote signatures. Writing in the air with hands can serve as a fun way to teach young s tudents how to write. The finger writing in the air system based on Kinect allows the user to write in the air in a natural, unconstrained way that might be an essential component for the next generation of HCI. The paper is aimed at evaluating the performance of an operating system on an embedded system. Before delv ing into it implementation, an introduction is needed to the parts involved in the paper. The whole report is centered around the field of embedded systems and the use of Linu x to run applications on them. Hence an introduction to Embedded Systems and using Linux as an OS in them is provided. An embedded system is a special purpose computer System that is designed to perform very small sets of design at activities. In 1960s, Embedded Systems used control
