Teaching Model-based Principles to HCI Practitioners
ABSTRACT: Human performance models, such as the GOMS Keystroke-Level Model (KLM), have been shown to successfully predict task completion times on interactive systems. Less reported is their actual use by HCI professionals. Starting with GOMS KLM and its variants, I will discuss their use in practice and some obstacles to their full adoption. Turning to performance models of web navigation, I present some challenges of extracting useful guidelines from the model that I developed. I'll then present findings from some of our recent studies evaluating various methods for selecting menu items, emphasizing our effort to create useful guidelines for practitioners. As I present findings, I'll share my experiences teaching these models to HCI practitioners in our masters program at DePaul.
