Page vii Preface The entertainment industry and the U.S. Department of Defense (DOD)—though differing widely in their motivations, objectives, and cultures—share a growing interest in modeling and simulation. In entertainment, modeling and simulation technology is a key component of a $30 billion annual market for video games, location-based entertainment, theme parks, and films. In defense, modeling and simulation provides a cost-effective means of conducting joint training; developing new doctrine, tactics, and operational plans; assessing battlefield conditions; and evaluating new and upgraded systems. Recognizing this synergy, DOD's Defense Modeling and Simulation Office (DMSO) asked the National Research Council's Computer Science and Telecommunications Board to convene a multidisciplinary committee to evaluate the extent to which the entertainment industry and DOD might be able to better leverage each other's capabilities in modeling and simulation technology and to identify potential areas for greater collaboration (see Appendix C for committee members' biographies). The committee met in June and August 1996 to plan a two-day workshop that was held in Irvine, California, in October 1996 (see Appendixes A and B for the workshop agenda and list of participants). It met again in November 1996 to discuss the results of the workshop and to plan the structure and format of this summary report. The workshop brought together more than 50 representatives of the entertainment and defense research communities to discuss technical challenges facing the two industries, identify obstacles to successful shar-

Participants were drawn from the film, video game, location-based entertainment, and theme park industries; DOD; defense contractors; and universities. They included top executives and government program managers as well as engineers, film directors, researchers from industry and academia, and university faculty. Through a series of presentations on electronic storytelling, strategy and war gaming, experiential computing and virtual reality, networked simulation, and low-cost simulation hardware, the committee attempted to encourage dialogue among these diverse stakeholders and stimulate discussion of research areas of interest to both the entertainment and defense industries. Because the workshop represented one of the first formal attempts to bridge the gap between the entertainment and defense communities, the committee also hoped to encourage personal contacts between members of the two communities as a means of facilitating future collaboration. As such, the 1996 workshop should be seen as part of an ongoing process that may continue beyond this project and this report. This report represents the committee's attempt to capture key themes of the workshop discussions. Chapter 1 provides an overview of the applications of modeling and simulation technology in the entertainment and defense industries and discusses the historical flows of technology between them. It also reviews the potential benefits to collaboration and outlines the underlying technologies of modeling and simulation in which collaboration may be possible. Chapter 2 identifies common technical needs of DOD and the entertainment industry, identifying and describing areas in which the entertainment and defense communities appear to have similar interests and in which collaboration, at some level, may be possible. Chapter 3 describes other issues that must be addressed in order to facilitate collaboration and sharing of research. These include the needs to develop the necessary human resources, establish mechanisms for information sharing and technology transfer, strengthen the research base, and overcome cultural differences between the two communities. As Chapter 3 notes, collaboration between the entertainment and defense research communities will require far more than a list of common research interests. Structures must be put in place to facilitate collaboration and to allow greater sharing of information between the two communities; differences in culture and business practices must be overcome, though not necessarily altered. Putting these elements in place will facilitate collaboration over time on an ever-changing set of common technologies and research areas. This report benefited from the contributions of many people throughout the modeling and simulation community. Workshop participants, through their presentations and discussion, provided the committee with

Page ix much of the material used in this report. The committee is especially grateful to those participants who submitted position papers outlining the research challenges in their particular fields of interest. The committee drew from these papers in preparing this report; the papers are reproduced in Appendix D. External reviewers of an early draft of this report also provided valuable comments. Staff members of the U.S. Army's Topographic Engineering Center and Joint Precision Strike Demonstration provided the committee with an informative demonstration of state-of-the-art military systems for battlefield visualization and real-time, man-in-the-loop, networked simulation. David Wray, of DMSO, provided hours of videotaped visual simulations for the committee to examine and excerpt. Several volunteers set up and operated a variety of entertainment and military demonstration systems during the 1996 workshop to provide participants with hands-on experience: Charles Benton of Technology Systems Inc., Michael Bilodeau of Spectrum HoloByte Inc., Steven Carter of Thrustmaster Inc., Leon Dennis of the Armstrong Laboratories at Wright Patterson Air Force Base, Brian Kalita of BBN Corporation, and Greg Lutz of Motorola's Government Electronics Division. Robin Scheer, of Spectrum HoloByte Inc., worked tirelessly to arrange the entertainment demonstrations and to contact participants for the strategy and war games session of the workshop. Fred Zyda orchestrated audiovisual presentations during the workshop, demonstrated video games for participants when called upon, and selected video clips and edited the videotape for the "Introductory Commonalities" presentation. Finally, thanks are due the sponsors of this study. Anita Jones, as director of defense research and engineering, conceived of the project and ensured its realization. James Hollenbach, Mark Jefferson, and Judith Dahmann of DMSO, with support from Terry Hines, of the MITRE Corporation, provided necessary guidance and support for the project and facilitated the participation of the defense community in its completion.
