ChatGPT is an impressive chatbot from OpenAI that is causing a lot of excitement and concern. Can it really write poems, papers, programs, etc. Well, let me share an example: I am a model railroader and for that hobby I asked it to, "Write an Arduino program that simulates a flickering campfire using an LED attached to pin 9.”  After two to three seconds, it gave me a program to do this (a program that looks to be correct) and followed it with a detailed explanation of how the program works.  Fascinating, but troubling as well.

My research efforts include working toward unique and interesting applications of augmented reality (AR) and virtual reality (VR) to safety workers and first responders, industrial and manufacturing concerns, digital entertainment, and the quality of life for people in general.

In another direction, I am working to improve the believability and playing ability of NPCs (Non-Player Characters) in first-person shooter video games. With the assistance of graduate students, I am evaluating various machine learning techniques that will permit the NPCs to learn by trial-and-error or by observation.

A paper is in the works that describes the application of evolutionary algorithms to create NPCs for the Capture the Flag mode of Unreal Tournament 2004.

Motion capture for interactive digital entertainment


The Department of CS operates a motion capture facility in the lab I use. It is comprised of an 8-camera Vicon system attached to an Intel Xeon, Windows-based computer with AutoDesk Maya and MotionBuilder software to create 3D models and manipulate them using the data captured using the Vicon system. This provides an excellent opportunity for students to experiment with the creation of realistic character animations for video games and films. This is the same technology Peter Jackson used to bring the character Gollum to life in his Lord of the Rings films.

"The idea that Bill Gates has appeared like a knight in shining armour to lead all customers out of the mire of technological chaos neatly ignores the fact tht it was he who, by peddling second-rate technology, led them into it in the first place" —Douglas Adams
