Interface and interaction design: How mobile touch devices foster cognitive offloading

Electronic Government (e-Government) systems are intended primarily to deliver governmental information and services through the web. The rapid evolution of mobile technology has triggered the need for conventional web-based e-Government systems to move towards another era known as Mobile Government (m-Government) systems. Although the functionality remains the same, the use of mobile devices in m-Government systems has caused the interface design of such systems to be dissimilar from the conventional web-based e-Government systems. Mobile devices in some ways have limited capacity in terms retrieving and displaying information, which makes their interface design to be quite tricky. This study aims to review the existing interface design frameworks in order to identify and collate the essential design elements that should be considered in designing the interface for m-Government systems. The study analysed qualitatively four m-Government interface design frameworks, namely 7Cs Design Elements, A Functional Design Approach for Mobile Government Website, Adaptive Mobile Government Framework and Framework of information Quality of Mobile Interface e-Government. By using content analysis, the study identified eight design elements from such frameworks. The study also highlighted the limitations of the current frameworks that could be explored further by future studies in interface design for m-Government systems.

Nurses Need Training and Policies to Address Barriers to Use of Mobile Devices and Apps for Direct Patient Care in Hospital Settings

At present, the website construction has become one of the necessary works of any industry. However, among hundreds of millions of websites, interface design is very convenient for people to use, and a small number of fast. The reason, including web interface design, web technology adoption, etc. will influence people to visit a website. Among these reasons, the interactive design of website interfaces and become the primary problem of experience that people visit the website. To address this problem, the current website interface and interactive design were discussed in this article, and try to propose improved method of most common small and medium-sized websites.

The present manuscript-based doctoral thesis addresses the question of how approaches to interaction design can be made more structured. This is an attempt to make it more transparent how one can come to a final design of a user interface starting from the results of foundational user research. The results of this analysis can help designers to work very systematic at times, to better reflect on their own idiosyncratic design process “on the job”, or to learn interaction design in the first place. In user-centered design (UCD) there are lifecycles and methods that already provide a certain degree of structuring with the discrimination of different phases etc. But they leave open some gaps here and there. This work is an attempt to close some of the gaps and bring closer together these individual methods. Interaction design patterns are a way to describe solutions to problems in designing user in-terfaces in a very systematic way. However, pattern libraries usually are far from complete. They mostly lack patterns to support the early phases of interaction design and therefore they do usually not link to the abstract models of conceptual design. The third manuscript describes an organizational scheme for interaction design patterns to support the process of implementing a complete pattern language covering all the different levels of the solution domain. The scheme has been found by analyzing several established UCD lifecycles and it has been evaluated by organizing all the individual patterns of several public pattern libraries into it. The first manuscript describes a process of systematically building up a pattern language alongside of a redesign project of a complex application in a corporate environment. The second manuscript describes how patterns have been evaluated in the aforementioned project, when there were several different solutions for one problem. This is shown with two interaction design patterns for the problem of making required input fields visible to users. The fourth manuscript is an attempt to bring together the idea of a complete pattern language, as a description of the solution domain of interaction design, with the different parts of the problem domain. Therefore, the same UCD lifecycles (as in the third manuscript) have been analyzed to find a universal structure of the problem domain. Then all the mappings between the individual parts of the two domains have been described in order to link the two domains in this direct way. Another way of looking at the gap between the problem domain and the solution domain is by seeing it as a distance of levels of abstraction between results of foundational user research and the final user interface. From this point of view a bridging of the gap can be seen in different intermediate representations (abstract models, sketches, and prototypes) and linking them together in a coherent way. These different ways of bridging the gap between foundational user research and the final design of a user interface can be seen as cognitive artifacts to foster problem solving and learning of interaction designers.

The design of mobile device interfaces is an area that has started to be addressed in the human computer interaction (HCI) community during the past few years. While previous work on handheld interface design has focused on overall usability aspects, security related design issues have only been minimally addressed. An example of a security interface is an authentication interface as used by electronic commerce (e-commerce) web sites. The paper opens with a review of prior research on secure interface design. Results of a usability evaluation targeting authentication interfaces as accessed on mobile devices is presented. To illustrate design aspects of an authentication interface, a discussion of the eBay authentication interface is then discussed. Recommended guidelines are proposed for designing authentication interfaces as accessed via mobile devices.

In this panel, we propose to figure out how requirements engineering and interaction design can be usefully combined. In particular, some people argue that scenarios/ use cases should be concrete, as in story-telling. Others argue for use of essential use cases as a methodological approach to interaction and user-interface design. Somewhat in the middle, it is argued that use cases should help acquiring the requirements in the first place. What should the practitioner believe and, in particular, do, in order to develop useful and usable software and systems? Software development and interaction design require different skills and different methods and are typically done by different people. Still, scenario-based design is proposed for several activities relevant for both tasks, such as requirements elicitation, software design, and interaction design. Symbolic modeling in this spirit is actually common to various fields. However, scenario-based approaches vary, especially with regard to their use, e.g., employing abstract use cases or integrating scenarios with functions and goals in a systematic design process. So, the key issue to be raised at the panel is how to combine different approaches, e.g., in scenario-based development, so that the interaction design as well as the development of the user interface and of the software internally result in an overall useful and useable system.

Usefulness of Mobile Devices in Learning Process for Residents of Pediatric Surgical Specialties

Purpose – This paper aims to identify systematic ways of linking club members’ behavioral and demographic characteristics to their use of mobile devices in clubs. While the traditional private club experience is characterized by intensive personalization and face-to-face interactions, clubs are increasingly deploying information technology (IT) tools to optimize some of their internal processes and offer a better value proposition to their members. Design/methodology/approach – Based on data from 737 actual club members from the USA, this research used a series of logistic regressions to reveal the manner in which a series of behavioral and demographic variables can be used to predict the likelihood of use of mobile devices in clubs for specific club-related tasks. Findings – This research revealed that there are differences between the two main types of clubs (i.e. golf/country and city/athletic), as well as differences among club members residing in different regions of the USA in the manner in which members use mobile devices for club-related tasks. Research limitations/implications – This research offers a number of notable theoretical contributions. This research uses actual mobile device use data from actual club members in the USA. In addition, this research offers a comprehensive operationalization of the actual mobile use behaviors in clubs, and offers a methodological blueprint for predicting mobile device user behavior using easily collectable variables. Practical implications – This research provides specific suggestions to pinpoint the mobile technology deployment in clubs according to behavioral and demographic profile criteria. Social implications – This research could lead to feasible segmentation procedures and explicates the increasing role of mobile devices within the contemporary society. Originality/value – This research addresses a novel research topic in an industry characterized by a grave lack of research on IT.

The increasing use of mobile devices among health sciences students presents both opportunities and challenges to problem-based learning (PBL) in face-to-face tutorials and during self-directed learning. The purpose of the present study was to find out how common the use of mobile devices is among students in PBL, how they are used, and whether some general recommendations can be made to help students make more effective use of mobile devices during PBL. Based on the findings of focus interviews of students and facilitators (Chan et al., 2015), the authors developed a self-administered online questionnaire to examine students’ usage of mobile devices in PBL. The students from three healthcare professional programmes in a university in Hong Kong were invited to take part in the online survey. A total of 346 students (response rate of 31.89 %) completed the online questionnaire. It was found that almost all of them (99 %) own one or more mobile devices. Most of them (98 %) used their mobile devices in PBL, usually for educational purposes, such as the search and synthesis of information and the use of specific software on these devices, especially those for the visualization of knowledge (like atlases or software for creation of concept maps). There was a small percentage of students who never used mobile devices in PBL. The reasons included the facilitators’ explicit discouragement of their use, and the desire to focus on the discussion instead of searching for information. Based on the findings of the survey, the authors arrived at four recommendations aiming at more effective use of mobile devices in PBL: students should be free to choose to use mobile devices; mobile devices should be used for educational purposes only, such as the search for factual information or multimedia files; PBL tutorial time should mostly be spent on discussion, instead of searching for information; students should be encouraged to use cloud-based services for collaborative activities such as note-making and concept mapping in PBL.

To examine the prevalence of mobility device use in U.S. community-dwelling older adults including older adults with cancer history ("survivors") and to estimate mobility disability noting variation by cancer history, cancer site, and other factors to improve early detection of mobility limitations. Cross-sectional analysis from the 2011 National Health and Aging Trends Study. In-person interviews in the homes of study participants. Nationally representative sample of community-dwelling Medicare beneficiaries, aged 65 and older (n = 6,080 including 1,203 survivors). Participants were asked about cancer history, pain that limited activity, mobility device use (eg, canes, walkers, wheelchairs, and scooters), history of falls, and medical conditions plus they were assessed for approximate mobility disability using a 3-m gait speed test. The results were scored on a scale of 0 to 4 (0 = lowest, 4 = highest) using criteria from the National Institute on Aging. A total of 19% of older adults and 23% of survivors reported using one or more mobility device, most commonly a single-point cane. Approximately 10% of breast, 6% of prostate, and 3% of colorectal cancer survivors reported using two or more devices in the past month. Survivors had lower mean gait speed scores (2.27) than adults without cancer history (2.39). In regression models, survivors were 18% less likely than adults without cancer history to score high on the gait speed test (odds ratio = .82; P < .05). Prior mobility device use, history of multiple falls, unhealthy weight, Black race, multimorbidity, and pain that limited activity were associated with lower gait speed scores in all participants (all P < .05). A greater proportion of older survivors used mobility devices than adults without cancer history. Mobility device use varied by cancer site and was highest in survivors of breast, colorectal, and gynecological cancer. Survivors were also more likely to show signs of mobility disability, based on gait speed, compared with adults without cancer history. These indications, although modest, suggest that older survivors may require special attention to functional changes in survivorship.

The use of metaphor is essential in user interface design, particularly for the mobile landscape, as the visual environment continues to be populated with more and more mobile electronic devices. A metaphor allows us to understand one concept in terms of another. Although considerable research has gone into the mobile technology, little attention has been paid to mobile interface metaphor, which is the key to user interaction. This paper explores the role of metaphor in interfaces in facilitating user interaction with mobile devices. It presents a classification of metaphors. It also proposes a framework with salient factors in relation to visual communication with metaphors. It also offers some thoughts on the use of new metaphors.

Mobility devices are crucial in enhancing activities and participation for individuals with mobility disability, particularly among the rapidly expanding population of older adults worldwide. This paper explores patterns of mobility device use among a nationally representative cohort of community-dwelling older adults in the United States, using data from the National Health and Aging Trends Study (NHATS) waves 1–9 (2011–2019). Our descriptive analysis focuses on the characteristics of incident mobility device use, its influencing factors, and related user experiences, aligning with the NHATS late-life disability framework. Mobility devices were categorized into walking aids (WAs), wheeled and seated mobility devices (WSMDs), and mixed use of both. We identified 2,943 incidents of mobility device use among 2,591 participants, spanning 47,722 person-years in community settings, yielding an incidence rate of 61.7 per 1,000 person-years. Over half (51.3%) of mobility device use ended in 1 year, with WAs being the predominantly used (63.8%). About one-third (30.5%) of these incidents involved a change in device combinations, with a notable shift towards WSMDs and mixed use over time. We found that older adults using WSMDs or changing their device combinations were in a more vulnerable state, while those using mixed devices or changing their device combinations experienced poorer user experiences. This study advocates for the implementation of rental and recycling programs, the involvement of NGOs and professional associations, and the adoption of flexible policies responding to the dynamic patterns of mobility device use among community-dwelling older adults. It also recommends expanding services to better serve vulnerable subgroups.

User interface design requires good visual design of metaphors, mental models, navigation, appearance, and interaction to represent data, functions, tasks, roles, organizations, and people. Techniques of simplicity, clarity, and consistency can improve the communication effectiveness of user interfaces for the Web, mobile devices and information appliances, and performance (productivity) tools. In particular, the use of appropriate typography, layout, color, animation, and symbolism can assist developers to achieve more efficient, effective communication to more diverse user communities.

BackgroundHealth care provider usage of mobile devices is increasing globally; however, there is little understanding of patient perceptions on this behavior in a health care setting.ObjectiveThe aim of this study was to assess patients’ attitudes toward mobile device usage by health care providers in the emergency department and to identify predictors of these attitudes.MethodsThe study was carried out at the emergency department of a large academic tertiary care medical center in Lebanon. A cross-sectional survey design was adopted by administering a questionnaire to medically stable adult patients who presented to the emergency department with an emergency severity index of 3, 4, or 5 between January 2017 and March 2018. The questionnaire collected relevant patient demographic information and included questions related to their mobile device usage along with those evaluating attitudes for the use of mobile devices by health care providers with respect to six major domains: role in health care, distraction potential, impact on communication, empathy, privacy, and professionalism. The attitude toward mobile device usage by health care providers in the emergency department was the main outcome variable. A stepwise logistic regression model was used to assess the association between the outcome variable and the demographic and attitude-related independent variables.ResultsAmong the 438 eligible patients, 338 patients responded to the questionnaire for a response rate of 70.0%. Overall, 313/338 (92.6%) respondents agreed that mobile devices improve health care delivery, whereas 132/338 (39.1%) respondents were opposed to their usage by health care providers in the emergency department (95% CI: 34.0-44.4). The majority (240/338, 71.0%) of patients agreed that mobile devices are a source of distraction to health care providers in the workplace. Females (odds ratio [OR]=1.67, 95% CI: 1.00-2.78) as well as all patients (OR=2.54, 95% CI 1.36-4.76) who believed that mobile devices were a source of distraction, reflecting a lack of professionalism (OR=2.77, 95% CI 1.59-4.82) and impacting the provider’s ability to relate to the patient (OR=2.93, 95% CI 1.72-4.99), were more likely to agree that mobile devices should not be used in the emergency department.ConclusionsPatients’ negative attitude toward mobile device use in the emergency department is largely driven by patient gender (females), patient perception of the distraction potential of the devices, and their negative impact on the health care provider’s empathy and professionalism. The findings of this study shed light on the importance of encouraging stakeholders to impose a digital professionalism code of conduct for providers working in acute health care settings.

It is not enough to get information technology (IT) users to adopt a secure behavior. They must also continue to behave securely. Positive outcomes of secure behavior may encourage the continuance of that behavior, whereas negative outcomes may lead users to adopt less-secure behaviors. For example, in the context of authentication, login success rates may determine whether users continue to use a strong credential or switch to less secure behaviors (e.g., storing a credential or changing to a weaker, albeit easier to successfully enter, credential). Authentication is a particularly interesting security behavior for information systems researchers to study because it is affected by an IT artifact (the design of the user interface). Laptops and desktop computers use full-size physical keyboards. However, users are increasingly adopting mobile devices, which provide either miniature physical keypads or touchscreens for entering authentication credentials. The difference in interface design affects the ease of correctly entering authentication credentials. Thus, the move to use of mobile devices to access systems provides an opportunity to study the effects of the user interface on authentication behaviors. We extend existing process models of secure behaviors to explain what influences their (dis)continuance. We conduct a longitudinal field experiment to test our predictions and find that the user interface does affect login success rates. In turn, poor performance (login failures) leads to discontinuance of a secure behavior and the adoption of less-secure behaviors. In summary, we find that a process model reveals important insights about how the IT artifact leads people to (dis)continue secure behaviors.
