ABSTRACT
The Keystroke Level Model (KLM) was developed to predict the performance time of expert users on desktop computing tasks. In recent years, computing technology has been implemented in more diverse environments, including the safety critical driving situation. In today’s world, computing technology is becoming increasingly ubiquitous, and there may be concerns that ergonomic techniques such as the KLM, which was developed for desktop computing situations, are no longer valid. As KLM predictions are associated with expert performance, it was required that participants were suitably skilled in the use of the in-car entertainment systems. KLM models of each task were created using the original rules set out by Card et al and task times were predicted. The strong correlations between the predicted task times and observed task times are encouraging. They corroborate other research, which has suggested that KLM techniques can be applied to computing environments that do not fit the desktop paradigm for which they were designed.
