Simulating Human Users in Dynamic Environments

In the discipline of Human-Computer Interaction, user interface design engineers have tools such as interface tool kits that assist them in development of the computer side of the interaction, but are lacking in tools for the human side. A kind of tool that would be valuable to design engineers is one that would evaluate and test different designs by interacting with them as a human user would, exhibiting the same constraints and variability as human users. As a step towards fulfilling this need on the human side, I developed a Simulated Human User and a Simulated Task Environment, named Argus, for the judgment and decision making domain.

The contribution presented here extends modeling human-computer interaction beyond the typical laboratory domain to a complex and dynamic domain. The domain is complex in the sense that many aspects of the task are unconstrained, thereby allowing users to adopt different interactive strategies (i.e. different combinations of user actions) to accomplish a task goal. The domain is dynamic in the sense that the environment changes over time and there is a time pressure to respond to the changes.
