From time to time, ACM SIGGRAPH has organized meetings centered around a specific theme to "bring together leading researchers and developers from a variety of disciplines to exchange state-of-the-art information and explore future directions for computer graphics." One such meeting on Perceptually Adaptive Graphics was held in Snowbird, Utah, in May of 2001 (http://isg.cs.tcd.ie/campfire/). This gathering brought together graphics researchers and vision scientists as well as others interested in the cross-section between the two fields. It formed the genesis of the ACM Symposium on Applied Perception in Graphics and Visualization (APGV), the success of which is evident in these proceedings.From its beginnings, APGV has continued this tradition of fostering interaction between computer graphics and vision science. By definition, computer graphics and visualization produces stimuli to be viewed by humans. The more that is known about the human visual system, the better such stimuli can be matched to those viewing them. This is a rich area where perception researchers can see their work applied directly. On the other hand, computer graphics techniques are maturing rapidly, and now constitute a viable approach to producing stimuli for use in psychophysics, thereby bypassing some of the difficulties inherent in experimental design. For instance, complex stimuli are easier to create using algorithms drawn from graphics.The first ACM Symposium on Applied Perception in Graphics and Visualization was held in Los Angeles in 2004, and was co-located with SIGGRAPH --- the premier conference in computer graphics. To promote greater participation of the perception community, the second symposium was co-located with the European Conference on Visual Perception (ECVP), held last year in A Coruña, Spain. This year, APGV is once more co-located with SIGGRAPH, and is held in Boston, July 28--30, 2006. Alongside the establishment of APGV, the Snowbird meeting was the spark needed to create a related ACM journal as well, called ACM Transactions on Applied Perception. It has a wider focus than APGV, and aims to foster interdisciplinary research which involves both perception and computing (i.e. not limited to computer graphics). This journal works in close collaboration with APGV, and has produced a special issue for each of the two preceding APGV symposia. These special issues publish a selection of the best APGV papers in expanded format.New this year is the establishment of a dedicated website for APGV: http://www.apgv.org, which will host all information pertinent to this symposium. In addition, a steering committee was established that will oversee the continuity between successive symposia, and will coordinate their organization. The steering committee is currently composed of Heinrich Bülthoff, Alan Chalmers, Victoria Interrante, Ann McNamara and Erik Reinhard. Getting involved with the organization of APGV is highly encouraged, and any of the steering committee members would be delighted to listen to your ideas and suggestions.The papers submitted to this year's APGV were of the usual very high quality. We have accepted 20 out of 45 submissions for paper presentation. The poster program drew a further 22 posters. These statistics are very much in-line with previous years' efforts, as shown in Table 1. APGV thus continues to attract strong contributions in a wide range of topics. As a result, we are very pleased to present the Proceedings of the Third Symposium on Applied Perception in Graphics and Visualization.
