Book excerpt: Dear Reader! Welcome to the proceedings of the First International Conference on Intelligent Human Computer Interaction (IHCI 2009) organized by the Indian Institute of Information Technology Allahabad. This is the first International Conference focused on Human Computer Interaction being organized in India. There is an increased interest in the human factors issues of computer use with a number of systems. The conference aims to provide an excellent opportunity for the dissemination of interesting new research, discussion about them and the generation of new ideas in these areas. We planned to organize the conference around the following five tracks: Signal and Vision Processing Language Processing Cognitive modeling Sensors and Embedded systems for HCI Graphics, Animation and Gaming Graphics, Animation and Gaming, Signal and Vision Processing, Language Processing and Cognitive modeling attracted due attention in the conference program. Very few papers were submitted in Sensors and Embedded systems and Graphics and Animation. Language is the primary means of communication between humans though usually neglected from HCI perspective. It will be better if human-computer interaction can be done in the same model as human-human communication. This was the main motivation behind including Language Processing as a separate track in the conference. However, some of the papers could not really achieve the application aspect from the HCI perspective. We will improve on this point in the next conference.
