ACT-R has been used to study human-computer interaction, however, up until the creation of JSegMan, ACT-R was unable to interact with unmodified interfaces not written in Common Lisp. Working with unmodified interfaces reveals deficiencies with ACT-R’s motor module. Currently, ACT-R is capable of queuing rapid keystrokes, however, many programs require multiple keys to be pressed at once, which ACT-R cannot do. This prevents ACT-R from interacting with text editors such as Vim and Emacs. Similarly, ACT-R cannot model people playing many modern video games that require pressing multiple WASD or arrow keys at once while moving the mouse. This paper creates a model that demonstrates this deficiency while playing Desert Bus. Furthermore, new systems to allow parallel motor actions to be learned and requested are proposed and the implications of running a model over many hours is explored.


Thanks for introducing an exciting project! I think Desert Bus is an interesting task to integrate perceptual-motor issues, and emotional issues (e.g., fun, fatigue, motivation). My question is about the possibility of including learning in your model. Some learning mechanism may help to solve the encountered perceptual-motor issues (failure of tem...
