Abstract

As humans interact with more complex automation systems it is important for designers to understand the cognitive aspects of tasks to be performed by some future complex system. However, this process can be very time consuming and expensive while the available tools are difficult to use and inflexible in their output representation. The proposed Cognitive Characteristics Tool (CCT) is a low cost yet thorough and easy-to-use solution for conducting a cognitive task analysis. The tool provides several unique functions. First, the CCT provides a systematic method to decompose each task and identify the cognitive characteristics needed to perform the task. Second, unlike many other task analysis tools, the CCT decomposes each task using multiple cognitive dimensions (e.g. attention, working memory, coordination requirements, etc). By decomposing each task into its cognitive components, HCI designers can obtain a better understanding of the characteristics that contribute to workload, task difficulty, and human error. The tools support a systematic decomposition of cognitive processes in task execution and some a priori levels for quantification. Finally, embedded algorithms support multiple analyses that allow researchers to assess impact across multiple dimensions as well as a flexible combination of these dimensions. This tool could be realized within analytic software such as Microsoft Excel.
