The Web-Based Usability Heuristic Survey Supports User Satisfaction

Competition between companies is now getting stronger strongly related to the company's mechanism in providing the services provided. Companies can build ways that can maintain customer loyalty. The approach can be done with web-based Usability Testing adopting an application user acceptance model, a usability aspect analysis that acts as a customer who enjoys a company's products and services. At present, there are already many theories of user acceptance models for an application. One of them is the user satisfaction model (User Satisfaction). This review specifically also identifies that content content has a significant positive effect on website visitor satisfaction

Conceptual Model of Digital Storytelling (DST)

Digital storytelling (DST) is an evolution of the age-old traditional storytelling, by augmenting the power of storytelling via the latest technology. In order for a digital storyteller to construct a digital story, there are sets of guided elements to be followed. However, these experts-proposed elements vary; while some are repetitive others do not cater for interactivity. Therefore, the main aim of this study is to identify the commonality of the diverse elements used by the different experts to eliminate their redundancy. By doing so, this study can identify the DST core elements and present them in the form of a conceptual model. In achieving the main aim, three sub-objectives were constructed; (1) to identify the core elements of digital storytelling that represent interactive and non-interactive forms, (2) to construct a conceptual model of the identified DST core elements, (3) to evaluate the proposed conceptual model by DST experts and potential users. In ensuring that the study is guided and focused, four phases of methodology were followed through: (1) groundwork, (2) induction, (3) iteration, and (4) conclusion. Eventually, the conceptual model was reviewed by five international experts and evaluated by 62 potential users. The evaluation on the quality of the model encompassed the following constructs: Perceived Ease of Understanding, Perceived Usefulness, User Satisfaction, and Perceived Semantic Quality. The findings indicated that the respondents perceived the conceptual model as having quality (mean score of 4.936 over a scale of 7.000). T-Test also revealed that there is no significant difference between the perception of those with experience in developing DST and those without experience. This suggests that the conceptual model consisting of the DST core elements, which is the main contribution of the study, could guide digital storytellers in developing digital story

The assessment of usability of electronic shopping: A heuristic evaluation

Today there are thousands of electronic shops accessible via the Web. Some provide user-friendly features whilst others seem not to consider usability factors at all. Yet, it is critical that the electronic shopping interface is user-friendly so as to help users to obtain their desired results. This study applied heuristic evaluation to examine the usability of current electronic shopping. In particular, it focused on four UK-based supermarkets offering electronic services: including ASDA, Iceland, Sainsbury, and Tesco. The evaluation consists of two stages: a free-flow inspection and a task-based inspection. The results indicate that the most significant and common usability problems have been found to lie within the areas of ‘User Control and Freedom’ and ‘Help and Documentation’. The findings of this study are applied to develop a set of usability guidelines to support the future design of effective interfaces for electronic shopping

Principles in Patterns (PiP) : Heuristic Evaluation of Course and Class Approval Online Pilot (C-CAP)

The PiP Evaluation Plan documents four distinct evaluative strands, the first of which entails an evaluation of the PiP system pilot (WP7:37). Phase 1 of this evaluative strand focuses on the heuristic evaluation of the PiP Course and Class Approval Online Pilot system (C-CAP). Heuristic evaluation is an established usability inspection and testing technique and is most commonly deployed in Human-Computer Interaction (HCI) research, e.g. to test user interface designs, technology systems testing, etc. The success of heuristic evaluation in detecting 'major' and 'minor' usability problems is well documented, but its principal limitation is its inability to capture data on all possible usability problems. For this reason heuristic evaluation is often used as a precursor to user testing, e.g. so that user testing focuses on deeper system issues rather than on those that can easily be debugged. Heuristic evaluation nevertheless remains an important usability inspection technique and research continues to demonstrate its success in detecting usability problems which would otherwise evade detection in user testing sessions. For this reason experts maintain that heuristic evaluation should be used to complement user testing. This is reflected in the PiP Evaluation Plan, which proposes protocol analysis, stimulated recall and pre- and post-test questionnaire instruments to comprise user testing (see WP7:37 phases 2, 3 and 4 of PiP Evaluation Plan). This brief report summarises the methodology deployed, presents the results of the heuristic evaluation and proposes solutions or recommendations to address the heuristic violations that were found to exist in the C-CAP system. It is anticipated that some solutions will be implemented within the lifetime of the project. This is consistent with the incremental systems design methodology that PiP has adopted

Heuristic Evaluations on Connect Carolina – UNC student information system

Connect Carolina is the student management system that is designed to manage student academic information. The usability of Connect Carolina is an important aspect of the system for many students, faculty, and staff who use the system. As the main system for UNC campus, Connect Carolina needs to be evaluated. This paper describes a heuristic evaluation for Connect Carolina with a comparison of student management systems from two other universities.Master of Science in Information Scienc

Optimizing Usability Studies by Complementary Evaluation Methods

This paper examines combinations of complementary evaluation methods as a strategy for efficient usability problem discovery. A data set from an earlier study is re-analyzed, involving three evaluation methods applied to two virtual environment applications. Results of a mixed-effects logistic regression suggest that usability testing and inspection discover rather disjunctive sets of problems. A resampling analysis reveals that mixing inspection and usability testing sessions in equal parts finds 20% more problems with the same number of session

Towards a Toolset for Intranet Evaluation

Usability is an important component of information systems acceptance. Independent consultants in the assessment of organisational intranets often perform heuristic appraisal, a common method of usability evaluation. However, there are alternative usability models that offer valuable analysis in the evaluation process. Using a government organisation’s intranet as a case study, this paper assesses the value of an independent heuristic-based intranet audit by providing a comparable approach to assessment realisable internally in the organisation using questionnaires. Using a single case study, we empirically apply the Technology Acceptance Model (TAM), together with some heuristic aspects, to provide an alternative tool for intranet usability and acceptance. We provide insight into the usability impact of intranet design changes, and compare the findings of an external usability audit with the approach outlined. An overall toolset for intranet evaluation is proposed as an initial step for further exploration and potential use

E-commerce websites for developing countries – a usability evaluation framework

Purpose – The purpose of this paper is to develop a methodological usability evaluation approach for e-commerce websites in developing countries. Design/methodology/approach – A multi-faceted usability evaluation of three Jordanian e-commerce websites was used, where three usability methods (user testing, heuristic evaluation and web analytics) were applied to the sites. Findings – A four-step approach was developed to facilitate the evaluation of e-commerce sites, mindful of the advantages and disadvantages of the methods used in identifying specific usability problems. Research limitations/implications – The approach was developed and tested using Jordanian users, experts and e-commerce sites. The study compared the ability of the methods to detect problems that were present, however, usability issues not present on any of the sites could not be considered when creating the approach. Practical implications – The approach helps e-commerce retailers evaluate the usability of their websites and understand which usability method(s) best matches their need. Originality/value – This research proposes a new approach for evaluating the usability of e-commerce sites. A novel aspect is the use of web analytics (Google Analytics software) as a component in the usability evaluation in conjunction with heuristics and user testing

Visual aesthetics and user experience: a multiple-session experiment

The article reports a longitudinal lab experiment, in which the influence of product aesthetics and inherent product usability was examined over a period of 7 weeks. Using a 2 × 2 × 7 mixed design, visual aesthetics (high vs. low) and usability (high vs. low) were manipulated as between-subjects variables whereas exposure time was used as a repeated-measures variable. One hundred and ten participants took part in the study, during which they carried out typical tasks of operating a fully automated coffee machine. We measured user experience by using the following outcome variables: perceived usability, perceived attractiveness, performance, affect, workload and perceived coffee quality (gustatory aesthetics). We found no effect of visual aesthetics on user experience (including perceived usability as the chief outcome variable), which is in contrast to a considerable number of previous studies. The absence of such an effect might be associated with influencing factors that have not yet been given sufficient attention (e.g., user identification with product, sensory dominance, characteristics of specific products)

Effect of user sessions on the heuristic usability method

Heuristic evaluation (HE) is a widely used method for assessing software systems. Several studies have sought to improve the effectiveness of HE by developing its heuristics and procedures. However, few studies have involved the end-user, and to the best of the authors' knowledge, no HE studies involving end-users with non-expert evaluators have been reported. Therefore, the aim of this study is to investigate the impact of end-users on the results obtained by a non-expert evaluator within the HE process, and through that, to explore the number of usability problems and their severity. This article proposes introducing two sessions within the HE process: a user exploration session (UES-HE) and a user review session (URS-HE). The outcomes are compared with two solid benchmarks in the usability-engineering field: the traditional HE and the usability testing (UT) methods. The findings show that the end-user has a significant impact on non-expert evaluator results in both sessions. In the UES-HE method, the results outperformed all usability evaluation methods (UEMs) regarding the usability problems identified, and it tended to identify more major, minor, and cosmetic problems than other methods.</jats:p
