Exploratory Research On Face Recognition Based Human-Computer Interaction

The invention of the computer to the human society has a huge influence. With the increase in hardware computing speed and storage capacity expansion, a variety of application software and management system is constantly developed and the manner of human-computer interaction is also undergoing profound changes. Graphical user interface greatly facilitate the use of ordinary computer users, but it still has so many restrictions that the computer is difficult to really integrate into people's work and life. People want the computer is able to listen, to see, to speak, or do these work even better than people, and can carryout real-time processing. A new interactive way becomes an urgent need for the development of computer technology. Personification of computer systems, computer miniaturization, portable technology and embedded technology will be two important trends for using computer, but human-computer interaction technology is one of the bottlenecks. Human-centered, natural manner will be the main direction for the new generation of efficient human-computer interaction.One goal of the pervasive computing is to let the computer become invisible, with not providing a sense of the operation, while able to provide people with ubiquitous computing and information services. In the research of computer vision, speech recognition, gesture input and sensory feedback of the new interactive technology, the face recognition because of it's has great future in the area of authentication, file management and video conferencing, is increasingly becoming the focus in the field of research of human computer interaction. The gaze tracking can be replaced has attracted psychologists, interactive technical experts attention, because it can take the place of keyboard and mouse to help disabled people and pilots to achieve the function of moving and input.The author researched a lot of access to human-computer interaction and computer vision on academic papers and literature at home and abroad in recent years, discussed the basic design of the human-computer interaction methods and a framework for pervasive computing, introduced the face detection and recognition of the general process and methods, and made its concrete realization of a more in-depth discussion, then proposed a framework protocol used to extend the functionality of third-party software to embed human-computer interaction seamlessly into the existing system based on computer vision. The main work includes the following:(1) Summarizes the significance of this research topic and prospects, reviewed human-computer interaction, computer vision research status, and summarizes the future development trends;(2) Interactive framework on pervasive computing are briefly analyzed and discussed the interaction of the two design methods, then discussed with examples in practical projects use and compared the two different methods of design process;(3) Based on face detection and recognition of the most popular currently open source computer vision library, the algorithm of detection and recognition is discussed in detail, and completed the development of face recognition systems;(4) Proposed a framework protocol to achieve human-computer interaction based on computer vision, which can be used by the third-party applications to provide functional extensions. Then the system is able to response to eye movements that were captured by the camera only by defining interaction description in the script file additionally.
