Models to Extend the Scope of Usability Testing for Telemedicine Systems

Some of the changes brought about by the introduction of telemedicine into healthcare organisations can be partly addressed by a better consideration of usability in telemedicine system design. Nevertheless, the costs of performing pre-deployment usability testing often make it infeasible. Moreover, usability problems are difficult to foresee, even more so if the system is to be deployed in several contexts differing in key aspects related to the user, task or environment or at different scales. We propose a structured methodology, together with a work-in-progress modelling approach, which can help predict whether usability problems would appear in a telemedicine system in new contexts, and if so, which.
