As technology becomes pervasive in our environment, professionals in the field of human-computer interaction (HCI) have the opportunity to enhance the quality of life through innovative design and application of technologies. Learn how to influence the future directions of HCI through a diverse program in which participants learn from and interact with the thinkers behind the solutions to today's difficult design problems.

The ACM annual conference on Computer-Human Interaction, CHI 2009, is the premier worldwide forum for exchanging information on all aspects of how people interact with computers. From April 4-9, researchers, practitioners, educators and students will meet in Boston, Massachusetts, to explore the future of computer-human interaction. CHI 2009 features world-class presentations including: two plenary sessions, dynamic interactive sessions, 26 courses, exhibits, recruiting and more at the Hynes Convention Center.

This year's conference offers a many presentations that examine the cultural and social dimension of interaction design: Jan Chipchase, of Nokia Research, will speak about "Designing for Global Impact". A panel presentation examines "Mobile Technologies for the World's Children", and another session examines "Mobile Applications for the Developing World". Social Computing is also discussed in a panel on "Creativity, Challenges, and Opportunities in Social Computing" and a special interest group session called "Research Ethics in the Facebook Era".
