| description | Designing a usable learning application is one
of the key factors in ensuring effective learning. This article introduces modified group usability testing (MGUT) as a feasible framework for evaluating the usability of nonimmersive virtual reality (VR) learning applications. Conventionally, usability testing of such learning applications often employs the one-to-one approach in which an evaluator conducts testing with several individual participants. As opposed to the one-to-one approach, the group approach involves several-to-many participants performing tasks simultaneously, with several evaluators observing and interacting with participants. This article describes the complete step-by-step procedure for conducting MGUT to uncover usability problems of a VR learning application that aims to educate its users on fire safety and prevention.
It also proposes methods to analyze these usability problems.The effectiveness and efficiency of MGUT was then compared with DGUT, the original group testing technique and cooperative evaluation (CE), which is a typical one-toone approach. Results indicate that all three techniques are able to reveal usability problems of different usability factors and show similar capability to discover the most critical and serious problems. MGUT is more effective than DGUT as it can collect additional usability problems of various factors and of different levels of severity. MGUT is as effective as CE as both techniques can identify usability problems which are more or less comparable in terms of quantity and quality. As for efficiency, MGUT and DGUT are more efficient than CE as these group testing approaches require lesser testing time, lesser effort in terms of the intensive interaction with participants although with slight more effort in the preparation of the physical setting. In addition, it is also obvious that MGUT and DGUT involve richer participation than CE. MGUT is also more
feasible than DGUT as it allows some flexibility in the
computer arrangement setting. |
