This paper studies the usability methodologies for spoken dialogue web interfaces along with the appropriate designer-needs analysis. The work unfolds a theoretical perspective to the methods that are extensively used and provides a framework description for creating and testing usable content and applications for conversational interfaces. The main concerns include the design issues for usability testing and evaluation during the development lifecycle, the basic customer experience metrics and the problems that arise after the deployment of real-life systems. Through the discussion of the evaluation and testing methods, this paper argues on the importance and the potential of wizard-based functional assessment and usability testing for deployed systems, presenting an appropriate environment as part of an integrated development framework.

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.

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.

Usability testing is typically taught with a desktop or mobile device in mind. As new platforms become more commonplace, it is important to master usability testing as applications scale cross-platform (including television, virtual reality, voice user interfaces, and screen readers). For all devices, there are key considerations across study recruitment, selection of the right prototype fidelity, lab research (including lab environment, observing, and recording the participant), and moderated remote research that should be kept in mind. This paper aggregates best practices for all six devices across these various topics.

Online Stores

The volume of the online commerce market is growing steadily; however, the online store conversion remains at a fairly low level. One of the reasons for the low conversion rate of online stores is the lack of the ergonomic design. The interface expert assessment and usability testing allow identifying interface errors of existing sites. The methodology is proposed for testing the ergonomics of the graphical user web interface of online stores based on choosing alternatives and visual analytics. The methodology is based on combining expert assessment of user interfaces with usability testing throughout the design process. Expert assessment is a quick way to find the main ergonomic problems, which is recommended to be used at the stages of developing technical specification, prototyping and final testing. The expert assessment mechanism of ergonomics is improved based on interface checklists and visual analysis of results. Within each of the ergonomics criteria (speed, errors, subjective satisfaction, comprehensibility), uniquely defined characteristics are selected to evaluate the ergonomics of the online store interface. Each ergonomic characteristic is assigned a weighting coefficient that determines its importance. The degree and quality of implementing the characteristics on a 0 to 5 scale are taken into account. Acceptable test results are obtained for the peer review method of the online stores interfaces for comparing the interfaces of Eldorado, M.Video and DNS sites.
