Contemporary software systems focus on usability and accessibility from the point of view of effectiveness and ergonomics. However, the correct usage of the domain dictionary and the description of domain relations and properties via their user interfaces are often neglected. We use the term domain usability (DU) to describe the aspects of the user interface related to the terminology and domain. Our experience showed that poor domain usability reduces the memorability and effectiveness of user interfaces. To address this problem, we describe a method called ADUE (Automatic Domain Usability Evaluation) for the automated evaluation of selected DU properties on existing user interfaces. As a prerequisite to the method, metrics for formal evaluation of domain usability, a form stereotype recognition algorithm, and general application terms filtering algorithm have been proposed. We executed ADUE on several real-world Java applications and report our findings. We also provide proposals to modify existing manual usability evaluation techniques for the purpose of domain usability evaluation.

AbstractIn this paper we design novel techniques for manual domain usability evaluation. Domain usability is the aspect of a particular user interface that relates to its terminology, hierarchy of terms, feature descriptions and icons, used language and consistency. However, domain usability is often neglected not only by software developers, but also by many researchers. The design of formal means to evaluate existing user interfaces would aid the development of better, domain-usable user interfaces. We designed six qualitative evaluation techniques and one formal evaluation technique based on System Usability Scale (SUS). To show the viability of the designed techniques, we demonstrate each of them in the domain of gospel music. Two of the techniques were used to experimentally verify the impact of specific domain usability aspects on usability and user experience. In this paper we also focus on the equality of the domain usability aspects with the goal of designing domain usability metrics. The preliminary design of the metrics is also presented in this paper and areas of future research are suggested.

This paper proposes a concept of a new approach to the development of speech recognition systems using multi-agent neurocognitive modeling. The fundamental foundations of these developments are based on the theory of cognitive psychology and neuroscience, and advances in computer science. The purpose of this work is the development of general theoretical principles of sound image recognition by an intelligent robot and, as the sequence, the development of a universal system of automatic speech recognition, resistant to speech variability, not only with respect to the individual characteristics of the speaker, but also with respect to the diversity of accents. Based on the analysis of experimental data obtained from behavioral studies, as well as theoretical model ideas about the mechanisms of speech recognition from the point of view of psycholinguistic knowledge, an algorithm resistant to variety of accents for machine learning with imitation of the formation of a person’s phonemic hearing has been developed.

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.

In the last decade the component technologies have evolved from object-oriented to serviceoriented ones. Services are seen as utilities based on a pay-for-use model. This model requires providing and guaranteeinga certain Quality of Service (QoS). However, QoS and even a service itself can be defined and understood in many different ways. It is by far not obvious which of these approaches and in what extent they should be used when developing service-oriented software systems. This paper analyzes the notion of QoS namely from this point of view.

The Web

Many of the world’s natural history collections are creating high resolution digital images of their specimens. They often make these available on the web through some form or zoomable viewer. For historical reasons, a hotchpotch of technologies are used to achieve this. This diversity has lead to two issues. Firstly, maintenance becomes costly as technologies need replacing. Secondly there is little chance to share data between institutions or provide a unified user experience. A researcher visiting four different virtual collections may have four very different experiences. Similar issues exist in the archives and libraries disciplines. They also need to share high resolution, annotated images of the physical objects in their care. In response to this issue many have coalesced around the International Image Interoperability Framework (IIIF). IIIF is a set of shared application programming interface (API) specifications for interoperable functionality in digital image repositories. It separates the notion of a viewer, which may be used as part of a website or other application, and the web services that feed data to that viewer. By using a common API for serving data about images, different viewers can be used to view the same images, thus providing an upgrade path that does not require replacement of viewer and server software at the same time and allows different viewers to be used for the same image data. Potentially more importantly, it facilitates the construction of applications that view data from different collections as if they were in the same place. From the researcher’s point of view, the experience could be the same whether the virtual specimen is hosted locally or in a museum on another continent. There is one important thing that has been deliberately omitted from the IIIF standard. This has both enabled its rapid adoption but also makes it incomplete for building research applications. IIIF transmits no semantic data about the subject of the images, only labels. The IIIF data therefore needs to be bound to semantically rich data about the specimens being viewed, in some uniform way. Consortium of Taxonomic Facilities (CETAF ) specimen identifiers are now widely adopted by natural history collections in Europe. Each individual collection object is designated by a URI chosen and maintained by the institution owning the specimen (Groom et al. 2017, Güntsch et al. 2018, Güntsch et al. 2017, HYAM et al. 2012). Under Linked Data conventions, content negotiation is used at the server so that users accessing an object using a web-browser are redirected to a human-readable representation of the object, typically a web-page, whilst software systems requiring machine-processable representations are redirected to an RDF-encoded metadata record. CETAF specimen identifiers are therefore ideal partners for IIIF representations of specimens. But how should we join the two together in a semantically rich way that will be generally understandable? SYNTHESYS+ is a European Commission funded programme that facilitates collaboration and network building among European natural history collections. It is concerned with both physical and virtual access to the 390 million specimens of plants and animals housed in participating institutions. Under Task 4.3 of this project, we have been working to create a reliable way to link between the RDF metadata about specimens and images of those specimens in IIIF as well as from images of specimens back to metadata of those specimens. By January 2021, we aim to have ten exemplar institutions publishing IIIF manifest files linked to CETAF identifiers for a few million specimens and for this to act as a catalyst for wider adoption in the natural history community. This presentation gives an update on the rollout of these implementations, paying particular attention to the challenges of semantically annotating specimens with images.

Usability Evaluation Methods

Usability is a fundamental quality characteristic for the success of an interactive system. It is a concept that includes a set of metrics and methods in order to obtain easy-to-learn and easy-to-use systems. Usability Evaluation Methods, UEM, are quite diverse; their application depends on variables such as costs, time availability, and human resources. A large number of UEM can be employed to assess interactive software systems, but questions arise when deciding which method and/or combination of methods gives more (relevant) information. We proposeCollaborative Usability Evaluation Methods, CUEM, following the principles defined by the Collaboration Engineering. This paper analyzes a set of CUEM conducted on different interactive software systems. It proposes combinations of CUEM that provide more complete and comprehensive information about the usability of interactive software systems than those evaluation methods conducted independently.

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.
