A task-based design approach to the design of a software assistent for usability evaluation
Journal Title: Romanian Journal of Human - Computer Interaction - Year 2009, Vol 2, Issue 1
Abstract
The quality of interactive systems is an important concern that brings in front the ergonomic quality of the user interface. Formative usability evaluation aims at identification and analysis of usability problems as early in the develompment process. For this purpose, a detailed description is needed as well as a classification according to different criteria: impact, context, explanation and suggestion for improvement. An acurate description which is agreed by the evaluation team and communicated to designers improves the product quality and motivates the process of fixing usability problems. In this paper we present a task-based approach to the design of a software tool to assist evaluators during the tasks of collecting, organization and retrieval of usability problems. In the case of heuristic evaluation and / or guidelines-based evaluation the software tools should satisfy two kinds of requirements: providing with appropriate heuristics / guidelines and recording of usability problems. These requirements are resulting from a task analysis and lead to develop a flexible software tool that could be used either as a stand-alone tool or integrated with an existing tool for working with guidelines.
