From the Science and Technology program chairs

While ISMAR is expanding and reaching out to new communities, we proudly continue to present to you the best research papers in the field of Mixed and Augmented Reality. The technical program of ISMAR 2009, in the tradition of the proceedings of seven previous ISMAR, two ISAR, two ISMR, and two IWAR meetings, this year takes the form of a Science and Technology (S&T) track. This program is comprised of 24 papers, 28 posters, as well as an array of keynote talks, demonstrations, tutorials, workshops and the tracking competition. All of these elements of the program are the result of dedicated hard work by members of the conference committee and additional volunteers, and we would like to recognize their efforts.
