John Laird's Artificial Intelligence & Computer Games Research

General AI and Computer Games

A general, over-the-top paper attempting to rally people to work on artificial intelligence and computer games: Interactive Computer Games: Human-level AI's Killer Application. This was presented as an invited talk at the National Conference on Artificial Intelligence (AAAI) on August 2, 2000 with Michael van Lent.
A revised version of the above paper that emphasizes the different genres of AI in computer games: The Role of AI in Computer Game Genres. This will appear in a book someday. Written with Michael van Lent.
An article on using AI and games for research with details of the anticipation in Quakebot (see related paper below). Using a Computer Game to Develop Advanced AI, Computer, 34 (7), July 2001, pp. 70-75.
A more recent and briefer paper that gives an overview of our Research in Human-level AI using Computer Games.This was published in Communications of the ACM in January 2002.
I've written a short paper on Design Goals for Autonomous Synthetic Characters.

The first paper we wrote that describes interface Soar to Quake and Descent. van Lent, Laird, J. E., Buckman, J., Hartford, J., Houchard, S., Steinkraus, K., and Tedrake, R.

Haunt 2

We are now devoting our efforts to developing an adventure-style game where human-level AI characters really make a difference. We are doing it as a mod to Unreal Tournament. The working title is Haunt 2 (see this link for details of the original Haunt.). http://ai.eecs.umich.edu/~soar/sitemaker/projects/haunt/

Quakebot

A description of some experiments we have done with the Quakebot to test how human it behaves and whether we can modify some simple parameters to change skill levels: Creating Human-like Synthetic Characters with Multiple Skill Levels: A Case Study using the Soar Quakebot. This appeared in the AAAI 2000 Fall Symposium Series: Simulating Human Agents, November 2000.

· A technical examination of the Soar Quakebot with emphasis on its ability to use anticipation: It Knows What You're Going to Do: Adding Anticipation to a Quakebot. This appeared in the Agents 2001 conference. An earlier version first appeared in the AAAI 2000 Spring Symposium Series: Artificial Intelligence and Interactive Entertainment, March 2000: AAAI Technical Report SS-00-02.

· A comparison of AI in computer games to research on computer generated forces (CGF) for distributed training. This paper includes a shortened and updated version of some of the material in the following paper. It is targeted to the CGF community. An Exploration into Computer Games and Computer Generated Forces, The Eighth Conference on Computer Generated Forces and Behavior Representation, May 2000, Orlando FL.

· The games research uses the same technology we've used for simulating military pilots. This paper gives an overview of our military pilot simulation work and relates it to issues in computer game AI development. Sorry but not all of the figures came through to PDF. Laird, J.
