Design and usability assessment of DocManS: A document management system with security and social media features

A document management system (DMS) is required to handle any documents within an institution efficiently. However, several important features are lacking in the current DMS, such as security and social media features. This paper proposes a new solution to tackle the issues by developing a new document management system with security and social media features called DocManS. The development process and usability evaluation by users are presented in this paper. The usability assessment is performed with the use of the System Usability Scale (SUS) framework. The results show that the current version falls within the B range of the SUS framework and several enhancements for better usability in terms of social media sharing and privacy are recommended.

Methodology for Developing a Usability Assessment Questionnaire in Spanish as a Bilingual Strategy for Software Improvement

Usability is the characteristic of a software product of being effective and efficient and producing satisfaction for users and traditionally is assessed through questionnaires but most of them are only available in English. A software usability assessment questionnaire (SUAQ) is proposed in two languages: Spanish and English. The methodology comprises four stages: 1) questionnaire development, 2) administration, 3) statistical validation, and 4) sample size determination. Twenty items were evaluated in terms of clarity, consistency, and relevancy. Then, the SUAQ was administered to 95 respondents. Overall, reliability values were acceptable in Spanish and English version, respectively. The factor analysis was feasible since the KMO index, and the Bartlett sphericity test was statistically significant. Both versions of SUAQ were tested to determine their validity. The findings show that the proposed methodology is an effective usability assessment instrument and thus an effective software improvement tool from a bilingual approach.

Validation of copula-based weather generator for maintenance model of offshore wind farm

This article discusses the aspect of modeling weather conditions in marine environment for implementation in the offshore wind farm domain. It is clear that harsh sea weather conditions influence many characteristics of any offshore installation. The accessibility to the infrastructure, maintenance procedures, failure ratios of components, energy provision levels, or utilization of vessels—are the examples of weather-related issues connected to the offshore wind industry. Regarding the growing popularity of digital twin methodology, authors present a novel view to generate weather data with copula-based method. The results obtained are compared to selected historical data and implemented into the maintenance model. The selected indicators of maintenance service are used for usability assessment of proposed copula-based method.

Assessment of the Sedia HIV Self-Test Device: Usability and Performance in the Hands of Untrained Users in Johannesburg, South Africa

The prevalence of HIV across South Africa places a strain on testing facilities. The use of HIV self-testing (HIVST) devices has been identified as a strategy to ease the burden on these facilities. The usability and performance of the Asante HIV−1/2 Oral Self-Test (Asante) (Sedia Biosciences, Portland OR, USA) device by novice users was assessed and reported on, to inform for the implementation of such devices in South Africa and elsewhere. Convenience sampling was used. Participants used the Asante HIVST device and recorded their interpretation of their results. Participants’ interpretations were compared with those of trained professionals and, thereafter, verified using the rapid diagnostic testing algorithm. Out of the eligible participants, 410 of the 524 (78.2%) were between the ages of 18–35. The usability assessment indicates that 100% of participants used the HIVST device’s information leaflet. However, 19/524 (3.6%) of participants who yielded an invalid result due to critical errors were excluded from the primary efficacy analysis. The average usability score was 98.1%. The sensitivity and specificity results were, 94.7% and 99.8%, respectively. This study shows that the Asante HIV self-test, and similar devices, can be valuable in providing convenient HIV self-testing and immediately available results. To accommodate a greater number of inexperienced users, the instructions may need to be revised.

Individuation Based Usability of a Customized E-commerce Platform

The usability of interfaces is critical in commerce, as it can lead to increased productivity and revenue. However, employees often have different needs from a system based on their role within the company. Hancock, Hancock, and Warm (2009) suggested that applied scientists should embrace person-specific interactions as the world moves ever more toward individual customization. Magento is an open-source e-commerce platform that can be tailored to the needs of respective companies. In conjunction with a retail plant and flower sales company in Clearwater, Florida, we assessed the usability of a custom Magento interface, focusing on each employee’s individual needs in the organization using heuristic evaluation, usability assessment, and structured interviews.

1194WebGIS in epidemiology: Lessons from LionVu Usability Assessment within Pennsylvania, United States

Focus of Presentation LionVu, a web-based mapping tool using Leaflet JavaScript, was recently redesigned to better meet the needs of clinical, educational, and epidemiological audiences within Pennsylvania, United States, containing publicly available health-related and demographic data sets. In addition, the LionVu Usability Assessment, a 50-question online survey, was conducted to assess whether LionVu’s functionality and improved interface met the needs of its intended audiences. The aim of this qualitative data analysis was to assess the themes of the open-ended questions of the LionVu Usability Assessment to improve the tool. Findings Invitations to the LionVu Usability Assessment were sent in Spring 2020 (n = 123), with 23 who began (55% female), but only 10 completed the survey. The 23 participants were from academia (n = 10), professional settings (n = 10) or missing (n = 3). Six themes emerged as critical to improve LionVu’s functionality: improving documentation and training materials, enhancing map customizability, including tabular displays below the maps, adjusting the colour schema, saving outputs as files, and displaying maps side-by-side. Conclusions/Implications LionVu fills a niche in the health community by giving clinical, educational, and epidemiological audiences the ability to visualize and utilize health data at various levels of aggregations and geographical scales (i.e., state, county, zip code, etc.). Novel applications like LionVu can serve data for future purposes such as mapping and graphing in epidemiology. Key messages The usability study of LionVu provided important feedback for its future development. Lessons and best practices on developing comparable WebGIS applications, for clinical, educational, and epidemiological audiences, are addressed.

Remote Usability Assessment of Topic Visualization Interfaces with Public Participation Data: A Case Study

Citizen participation often faces challenges of transparency and accountability. Visualizations’s usability becomes key for public consultation activities. The tree map is frequently used to disseminate data and to give it back to the population. The purpose of this study is to understand how tree maps and stacked barcharts differ in terms of effectiveness, efficiency, and satisfaction in tasks, like solving topic categorization and comparison analysis tasks. An experimental design was used to examine user performance based on a task-based usability test. 34 participants interacted remotely with data visualizations from an open 2016 participatory constitution-making process. The ANOVA showed that stacked barcharts work significantly better for comparison tasks than the tree map, but there are no significant differences in regards to categorization tasks. Public participation initiatives should first determine what cognitive operations their users perform before deciding which visualization interfaces will be more useful for the intended public.
