Telepresence has the potential to assist older adults to stay socially connected and to access telehealth. Telepresence was initially created for office use, thus the usability of telepresence for older adults remains unknown and there is a lack of design recommendations, particularly those with an emphasis on users’ age-related needs and limitations. To bridge the gap, this study assessed two telepresence user interfaces (UIs). One UI was designed to mimic common features founds in commercially available telepresence systems. Another UI was designed based on design guidelines for older adults. Each UI was integrated to a virtual driving environment created via Unity. To assess the usability of both UIs, thirty older adults participated in usability testing. Questionnaires and semi-structured interview were administered following each UI test sessions. Results of this study provide insight on what usability features are critical for the aging population to use telepresence, such as high color contrast, automated controls, and consistent icons.

Context: Widgets are reusable User Interfaces (UIs) components frequently delivered in Web applications.In the web application, widgets implement different interaction scenarios, such as buttons, menus, and text input.Problem: Tests are performed manually, so the cost associated with preparing and executing test cases is high.Objective: Automate the process of generating functional test cases for web applications, using intermediate artifacts of the web development process that structure widgets in the web application. The goal of this process is to ensure the quality of the software, reduce overall software lifecycle time and the costs associated with tests.Method:We elaborated a test generation strategy and implemented this strategy in a tool, Morpheus Web Testing. Morpheus Web Testing extracts widget information from Java Server Faces artifacts to generate test cases for JSF web applications. We conducted a case study for comparing Morpheus Web Testing with a state of the art tool (CrawlJax).Results: The results indicate evidence that the approach Morpheus Web Testing managed to reach greater code coverage compared to a CrawlJax.Conclusion: The achieved coverage values represent evidence that the results obtained from the proposed approach contribute to the process of automated test software engineering in the industry.

Methodological Guidelines

User interfaces of computer applications encompass a number of objects such as navigation links, buttons, icons, and thumbnails. In this chapter, these are called interface signs. The content and functions of a computer application are generally directed by interface signs to provide the system’s logic to the end users. The interface signs of a usable application need to be intuitive to end users and therefore a necessary part of usability evaluation. Assessing sign intuitiveness can be achieved through a semiotic analysis. This study demonstrates how a semiotic assessment of interface signs’ intuitiveness yielded a number of benefits. For instance, (i) it provides an overall idea of interface signs’ intuitiveness to the end users to interpret the meaning of interface signs, (ii) it assists in finding usability problems and also in (iii) recommending possible solutions, (iv) provides background for introducing guidelines to design user-intuitive interface signs, (v) helps in constructing heuristic checklist from semiotics perspective to evaluate an application, (vi) no additional resource and extra budget are needed. This study also presents a list of methodological guidelines to obtain the perceived benefits of integrating semiotic perception in usability testing for practitioners.

In the 21st century, the ability of citizens to participate in online democracy is a key issue for governments in the developing nations because of its attendant benefits. Information and Communications Technology (ICT) facilities support the establishment of electronic interaction between citizens and the various organs of government. Towards this, a variety of efforts have been made, and many systems have been developed, but few attempts have been made to combine more than one mode of access for e-Democracy system. It is difficult for people with visual impairment to be involved in issues of governance and communicate with government representatives such as public office holders. For these people, having access to an electronic means of communicating with these representatives is necessary as a way of enhancing participatory democracy among the citizens. In this chapter, the authors propose an access method for e-Democracy system using Multimodal SMS, Voice and Web (Multi-SVW) system. The system was implemented using VoiceXML and PHP for the user interfaces and MySQL as the database. The system was evaluated using cognitive walkthrough strategy. The results of the usability evaluation suggest that the prototype Multi-SVW application presented in this chapter has “good usability” based on the total mean rating. The system provides accessibility options to citizens who are able-bodied and citizens who are blind or vision impaired as a way of promoting digital citizenship.

This chapter presents the state-of-the-art in usability issues and methodologies for VoiceWeb interfaces. It undertakes a theoretical perspective to the usability methodology and provides a framework description for creating and testing usable content and applications for conversational interfaces. The methodologies and their uses are discussed as well as certain technical issues that are of specific importance for each type of system. Moreover, it discusses the hands-on approaches for applying usability methodologies in a spoken dialogue web application environment, including methodological and design issues, resource management, implementation using existing technologies for usability evaluation in several stages of the design and deployment. Finally, the challenging usability issues and parameters of the emerging advanced speech-enabled web interfaces are presented.

AbstractProgramming environments have evolved from purely text based to using graphical user interfaces, and now we see a move toward web-based interfaces, such as Jupyter. Web-based interfaces allow for the creation of interactive documents that consist of text and programs, as well as their output. The output can be rendered using web technology as, for example, text, tables, charts, or graphs. This approach is particularly suitable for capturing data analysis workflows and creating interactive educational material. This article describes SWISH, a web front-end for Prolog that consists of a web server implemented in SWI-Prolog and a client web application written in JavaScript. SWISH provides a web server where multiple users can manipulate and run the same material, and it can be adapted to support Prolog extensions. In this article we describe the architecture of SWISH, and describe two case studies of extensions of Prolog, namely Probabilistic Logic Programming and Logic Production System, which have used SWISH to provide tutorial sites.

This chapter presents the WDP (Web Design Perspectives-based Usability Evaluation), an inspection technique specifically designed to assess the usability of Web applications. This technique combines Web design perspectives and the heuristic evaluation method proposed by Nielsen (1994b). In addition to describing the components of the WDP technique this chapter also illustrates its use in practice by means of an industrial case study where the technique is applied to inspect a real Web application. In this case study, developers and requirement assessment staff applied the WDP technique to evaluate the usability of modules developed from scratch for a Web application. The results of this case study indicate the feasibility of performing usability inspections with the participation of a software project’s stakeholders, even when stakeholders are not usability experts.

This chapter presents the state-of-the-art in usability issues and methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. It is planned to unfold a theoretical perspective to the usability methodology and provide a framework description for creating and testing usable content and applications for conversational interfaces. Main concerns include the problem identification of design issues for usability design and evaluation, the use of customer experience for the design of voice-web interfaces and dialogue, and the problems that arise from real-life deployment. Moreover, it discusses the hands-on approaches for applying usability methodologies in a spoken dialogue web application environment, including methodological and design issues, resource management, implementation using existing technologies for usability evaluation in several stages of the design and deployment.
