Improving the distributed evolution of software through heuristic evaluation
… hurdles to overcome. A developer-oriented evaluation of open architecture interfaces could help meet some of these challenges. In this thesis, I present a set of guidelines for designing a developer-oriented interface for software open architectures, developed through a survey of several …

Developing Heuristic Evaluation Methods for Large Screen Information Exhibits Based on Critical Parameters
Evaluation is the key to effective interface design. It becomes even more important when the interfaces are for cutting edge technology, in application areas that are new and with little prior design knowledge. Knowing how to evaluate new interfaces can decrease development effort and increase the …

Design and Usability Testing of an mHealth Application for Midwives in Rural Ghana
… mClinic prototype by conducting field testing, heuristic evaluation, and usability surveys. Additionally, low-fidelity prototyping was used to determine applicability of the other use cases to the midwives' environment. Midwives reported inability to access critical data, high patient loads, and …

A Case Study of the Effects of a Web Interface Redesign Based on Usability Guidelines.
… inspection. The results of user testing and heuristic evaluation suggest that the use of these guidelines in website redesign had a positive impact on user performance. A more conclusive result would have required a larger sample size and a redesigned testing protocol that varied the order in …

A Usability Problem Inspection Tool: Development and Formative Evaluation
… cost-effectiveness. However, methods like the heuristic evaluation are ad-hoc, lacking a theoretical foundation. Other, more formal approaches like the cognitive walkthrough are tedious to perform and operate at a high-level, making it difficult to sub-classify problems. This research involves …

Only Screen Deep? Evaluating Aesthetics, Usability, And Satisfaction In Informational Websites
… positive correlations in informational websites. Heuristics or guidelines for evaluating informational websites are developed based on empirical research and practitioner expertise. Categories for heuristic evaluation include usability, credibility, visual clarity, visual richness, and emotional …

Intelligent control system for CFD modelling software
… proposed by other researchers. It is argued that heuristic search is better suited to model the techniques used by human experts. The residual graphs are identified as the most important source of heuristic information relevant to the control decisions. Three different graph features are found to …

Bottleneck-based heuristic for permutation flowshop scheduling
The newly heuristic is developed by introducing the bottleneck-based concept that was applied at the beginning of initial solution determination. The heuristic is known as Bottleneck-Based (BNB) heuristic. The previous study found that the scheduling activity become complex when dealing with large …

Usability Problem Description and the Evaluator Effect in Usability Testing
Previous usability evaluation method (UEM) comparison studies have noted an evaluator effect on problem detection in heuristic evaluation, with evaluators differing in problems found and problem severity judgments. There have been few studies of the evaluator effect in usability testing (UT), …
