Given that heuristic evaluation (HE) is a popular evaluation method among practitioners despite criticisms surrounding its performance and reliability, there is a need to improve the method's performance. Several studies have shown HE-Plus, an emerging variant of HE, to outperform HE in both effectiveness and reliability. HE-Plus uses the same set of(More)
The lack of standard assessment criteria for reliably comparing usability evaluation methods (UEMs) is an important gap in HCI knowledge. Recently, metrics for assessing thoroughness, validity, and effectiveness of UEMs, based on user data, have been proposed to bridge this gap. This paper reports our findings of applying these proposed metrics in a study(More)
Research into the psychology of programming has been mostly related to textual programs. The application of the theory of programming to visual programs could be further supported by empirical evidence. Graphical readership, a skill that cannot be ignored in visual programming, has been little explored; similarly the case with regard to the effect of(More)
Historically, graphical programming and visual programming most commonly used arrows, lines or juxtaposition to represent visually the order or a sequence of actions. The choice of representation can affect the performance of a user of such systems in following a sequence of actions, both in terms of time and of accuracy. However, there is little empirical(More)
This paper explores the theories and practices underpinning Virtual Immersion, a discount technique proposed to help designers gain deep understanding of, and empathise with, their users. Four essential elements to this technique are identified and empirical evidence for its usefulness is provided. A study is reported in which the technique was applied to(More)
How can we keep technology-focused computing and software engineering students interested and engaged in a soft subject like HCI? How can we avoid leaving the less gifted and less enthused students behind in a 12-week module packed with theories, methodologies and with a new development tool to learn? This paper describes how educational research findings(More)
