Inspection-Based Evaluations

The fundamental purpose of usability inspection is to find and report any potential user difficulties for remedy in redevelopment. Ideally, a UIM would find all usability problems that may arise from use of an interactive system; in other words, it would be thorough and, hence, not miss any elements that may cause user difficulties. The final problem set achieved through usability inspection would also only comprise valid problem predictions, with no false alarms reported. Consequently, finding all problems without false alarms, the result of a usability inspection would be wholly effective.
Testing Performance Support Products

As noted above, heuristic evaluation should be done early in development after the first complete draft, or version, of the product is finished. There are various forms of heuristic evaluation. In simplest approach, the product is rated on the basis of a short list of questions, typically concerned with observed quality (e.g., spelling, grammar, appearance, consistency, apparent clearness of the content, etc.). A more involved process (often called “usability inspection”) utilizes experts or peers to inspect the product and to evaluate it in terms of a list of general heuristics (a set of usability principles). These general heuristics (Molich and Nielsen, 1990; Nielsen 1994) include such criteria as: Visibility of system stateUsing simple and natural dialogueProviding user control and freedomConsistency and standardsSpeaking the user’s languageMinimizing the user’s memory load (using recognition rather than recall)Providing feedbackProviding flexibility and efficiency of use (e.g., shortcuts)Helping users recognize, diagnose and recover from errorsProviding help and documentation

Recent studies with VR practitioners demonstrate that in addition to the user-centered testing approach, there is a need for a cost-effective formative evaluation method to help assess and iteratively improve usability in VR (Nebeling et al., 2020). The formative techniques can be used by designers and developers in the early stages of design to eliminate usability problems (Hartson & Pyla, 2012). One such example is Heuristic Evaluation methods (Nielsen, 1992), a discount usability inspection method that identifies usability issues with several experts. Thus it can support creators faster in obtaining quality answers to meaningful questions in the design-evaluation iteration. Several studies suggested that Heuristic Evaluation methods are still largely missing in the VR community (Dey et al., 2018; Sutcliffe et al., 2019).

Usability evaluation methods (UEMs) refer to the techniques evaluators use to identify usability problems that need to be addressed through the design and redesign of a system (Nyang’or et al., 2013). UEMs can be divided into three categories, namely user testing (UT), inspection and inquiry (Alghamdi et al., 2013).In employing a UT method, users are given specific tasks involving the use of the system, to test to what extent the system supports them in completing their tasks (Alghamdi et al., 2013).Usability inspection (also known as expert-based evaluation) examines usability-related problems from the system’s user interface (Alghamdi et al., 2013). Such inspection methods include cognitive and pluralistic walkthroughs, heuristic evaluation (HE), feature inspection and perspective-based evaluation (Usability Evaluation Website, 2012).By using inquiry methods, evaluators attempt to understand users’ interests (likes or dislikes) and needs, by asking them questions and observing them while they perform tasks (Usability Evaluation Website, 2012). Such methods include field observation, logging actual use, proactive field study focus groups and interviews (Usability Evaluation Website, 2012).

Furthermore, Friess (2015) stated that, usability testing is a different from of usability inspection in the way that, usability inspection relies on the assessment of professional evaluators while usability testing requires a recruitment of potential end users to interact with the website. Heuristic evaluation belongs to commonly applied form of usability inspection, where evaluators use well known usability principles (i.e. the “heuristics”) to find out usability problems.
