IMPROVING THE ERGONOMIC QUALITY OF AR-BASED E-LEARNING SYSTEMS: A TASK-BASED DESIGN APPROACH

Summary/Abstract: Augmented reality (AR) is a challenging technology for e-learning. Nevertheless, the benefits of AR in terms of increased engagement and motivation could be undermined by a low ergonomic quality. A challenge for designers is to provide students with a usable AR environment that is able to support an effective and efficient achievement of their learning goals. A user-centred design approach requires understanding users and the tasks they perform. This analysis focuses on task modelling and presents a task-based approach to the development of a Chemistry application implemented on an AR teaching platform. The task model enables an analysis of critical task sequences, helps to prevent potential usability problem, and provides with a basis for a task-based approach to evaluation.
