Developing advanced interface design guidelines from survey based and empirical research

The Guideline project is concerned with the interface and interaction issues of consumer product control and display devices. The main objective of the project is to produce interface design guidelines for emerging or advanced consumer based products for interaction and product designers. The information for the guidelines is being produced using two different approaches; these are empirically based guidelines produced within the project, using software based prototypes of three anticipated advanced interfaces, and information gathered from relevant human computer interaction (HCI) literature. This paper presents an account of the project as a case study and documents some of the findings that have emerged so far

Building a Web-Features Taxonomy for Structuring Web Design Guidelines

This paper proposes a framework for structuring web design guidelines that incorporates the hierarchies of web features and their semantic relationships with HTML and CSS. It is argued that this approach will be synchronous with the mental model of web designers, thus making the guidelines more usable. In addition, this approach embraces both external and internal aspects of web design, so there is little compromise on the coverage of web design issues. An experiment was conducted to compare the relative effectiveness of the proposed framework with other guideline structures (e.g., principle-oriented and a mixture of principle and feature-oriented). There was evidence that the principle-oriented guidelines performed worse than the other structures, but the analyses failed to establish that the proposed framework as the most effective. The experiment showed promising results but it suffered from small sample size. In spite of this, it is believed that the proposed taxonomy and framework has laid the groundwork for future research.Yeshttps://us.sagepub.com/en-us/nam/manuscript-submission-guideline

Promoting Bright Patterns

User experience designers are facing increasing scrutiny and criticism for creating harmful technologies, leading to a pushback against unethical design practices. While clear-cut harmful practices such as dark patterns have received attention, trends towards automation, personalization, and recommendation present more ambiguous ethical challenges. To address potential harm in these "gray" instances, we propose the concept of "bright patterns" - persuasive design solutions that prioritize user goals and well-being over their desires and business objectives. The ambition of this paper is threefold: to define the term "bright patterns", to provide examples of such patterns, and to advocate for the adoption of bright patterns through policymaking.Comment: For associated website, see https://brightpatterns.org/.

Procedurally Transparent Design Science Research: A Design Process Model

This paper presents a process model for Information Systems (IS) scholars conducting Design Science Research (DSR). The paper argues that the impact of DSR on the IS discipline has been inhibited by perceived limitations in the rigor of DSR studies, and that such perceptions are often due to a lack of procedural transparency surrounding the development process in DSR studies. To help address this issue, the paper presents the Process Model for increased Procedural Transparency (PMPT). A range of design literature is analyzed to identify and characterize the distinct stages of design-oriented research. These stages are laid out in a process model, which is then bound in a recursive instantiation, and demonstrated through an application. The paper concludes with a discussion of the contribution of PMPT, as well as opportunities for future research

thesisElectronic Health Record (EHR) adoption rates have been low in the United States. A key reason for this low adoption rate is poor EHR usability. Currently no standards exist for design, testing and monitoring the usability of EHRs. Therefore, we conducted a usability evaluation of a vendor's product in the Emergency Department at the University of Utah. In the first objective of this study, we evaluated a newly implemented computerized provider order entry application. Four usability experts used the Zhang et al 14 heuristics and 23 predefined tasks to perform the evaluation. The experts found 48 usability problems categorized into 51 heuristic violations. There were 4 cosmetic, 120 minor, 64 major, and 4 catastrophic problems identified. The interrater reliability was 0.81 using Fleis' Kappa, showing a high level of consistency in ratings across evaluators. For the second objective, we used an electronic version of Questionnaire of User Interaction Satisfaction (QUIS 7.0) to evaluate physician satisfaction with the CPOE application in the ED. The physician response rate was 50% (25/50). The total survey mean was 4.87, lower than the -a priori‖ definition for acceptable satisfaction score of 5.0 (of a possible 9). The lowest scale scores were for overall user reaction and learning iv and the highest were for screen, terminology and system capabilities. Further analyses were completed to determine any differences for satisfaction scores between physician trainees and attending. A multifactor ANOVA was performed to examine the combined effect of the different experience levels and sections of the QUIS. The results were significant at -1.43 (p < 0.05) for screen and terminology and system capabilities. In this setting, the ED CPOE application had a high level of usability issues and low mean satisfaction scores among physician end-users. The responsibility for improved usability lies with both vendors developing the product and facilities implementing the product and both should be educated on usability principles. The combination of a user-based and expert-based inspection method yielded congruent findings and was an accurate and efficient means of evaluation

Independent Verification and Validation of Complex User Interfaces: A Human Factors Approach

The Usability Testing and Analysis Facility (UTAF) at the NASA Johnson Space Center has identified and evaluated a potential automated software interface inspection tool capable of assessing the degree to which space-related critical and high-risk software system user interfaces meet objective human factors standards across each NASA program and project. Testing consisted of two distinct phases. Phase 1 compared analysis times and similarity of results for the automated tool and for human-computer interface (HCI) experts. In Phase 2, HCI experts critiqued the prototype tool's user interface. Based on this evaluation, it appears that a more fully developed version of the tool will be a promising complement to a human factors-oriented independent verification and validation (IV&V) process

Evaluating usability of e-commerce sites by tracking eye movements

The majority of existing e-commerce design guidelines has been derived by conducting heuristic evaluations, without reporting the involvement of the users themselves. This research provides clarification on a number of existing web design guidelines for e-commerce sites based on empirical studies with users. Four studies were conducted and each study focused on a specific set of design guidelines as found in the literature. A combined qualitative and quantitative approach has been used, including a state-of-the-art technique, eye tracking. The eye movement data were complemented by user-profile data elicited through background questionnaires and user-perception data as captured through semi-structured interviews. The first study investigated users’ initial impressions of homepages of e-commerce sites. The second study examined users’ adaptability to persistent or varied placement of design elements. The third and fourth studies explored the effect of the presentation format of e-commerce web pages: the first in terms of the proportion of images, and the second in terms of how key icons related to an e-commerce transaction were presented. On the whole, the results of the studies corroborated existing design guidelines, but they also identified potential refinements. The thesis contributes both methodologically and empirically to Human-Computer Interaction. The combined methodological approach enables insight into the user experience that spans behavioural aspects such as visual search behaviour and visual search performance data, and subjective aspects such as user expectations and preferences. The empirical outcomes amplify the design guidelines from a user’s perspective
