Access to recorded interviews: A research agenda

Recorded interviews form a rich basis for scholarly inquiry. Examples include oral histories, community memory projects, and interviews conducted for broadcast media. Emerging technologies offer the potential to radically transform the way in which recorded interviews are made accessible, but this vision will demand substantial investments from a broad range of research communities. This article reviews the present state of practice for making recorded interviews available and the state-of-the-art for key component technologies. A large number of important research issues are identified, and from that set of issues, a coherent research agenda is proposed

New taxonomy of easy-to-understand access services

The Convention on the Rights of People with Disabilities states that access to information through written and electronic communications is essential for personal development and full participation in society. In digital scenarios, media services, such as audio descriptions, subtitles, or sign language, facilitate access to content with a focus on sensory barriers. Still, there are shortcomings in addressing other needs, such as cognitive ones. This article aims to suggest a taxonomy of the emerging easy-to-understand access services that cater for the needs of audiences who struggle with understanding audiovisual content for varied reasons, such as low literacy, reading or learning difficulties, temporary impairments, or insufficient language skills. The taxonomy uses Gottlieb’s (2005) semiotically-based classification to define E2U access services within the landscape of Audiovisual translation and to classify them according to their semiotic identity as compared to the standard access services.La Convención sobre los Derechos de las Personas con Discapacidad establece que el acceso a la información escrita y electrónica es esencial para el desarrollo personal y una participación social plena. En escenarios digitales, los servicios de accesibilidad como la audiodescripción, el subtitulado o la lengua de signos facilitan dicho acceso, especialmente en el caso de barreras sensoriales. Sin embargo, en el ámbito cognitivo aún quedan barreras por salvar. Este artículo presenta una taxonomía de servicios de accesibilidad que usan métodos de simplificación para facilitar el acceso a personas con dificultades de comprensión, ya sea por problemas de lectura, aprendizaje, discapacidad temporal o niveles insuficientes de lengua. La taxonomía presentada utiliza la clasificación semiótica de Gottlieb (2005) para ubicar estos servicios de accesibilidad dentro de la traducción audiovisual y para clasificarlos según su identidad semiótica en comparación con los servicios de accesibilidad estándar.This article has been partially funded by the EU project IMAC grant number 761974, EASIT 2018-1-ES01-KA203-050275, RAD PGC2018-096566-B-I00 and the Catalan Research Council grant number SGR113

Quality assessment technique for ubiquitous software and middleware

The new paradigm of computing or information systems is ubiquitous computing systems. The technology-oriented issues of ubiquitous computing systems have made researchers pay much attention to the feasibility study of the technologies rather than building quality assurance indices or guidelines. In this context, measuring quality is the key to developing high-quality ubiquitous computing products. For this reason, various quality models have been defined, adopted and enhanced over the years, for example, the need for one recognised standard quality model (ISO/IEC 9126) is the result of a consensus for a software quality model on three levels: characteristics, sub-characteristics, and metrics. However, it is very much unlikely that this scheme will be directly applicable to ubiquitous computing environments which are considerably different to conventional software, trailing a big concern which is being given to reformulate existing methods, and especially to elaborate new assessment techniques for ubiquitous computing environments. This paper selects appropriate quality characteristics for the ubiquitous computing environment, which can be used as the quality target for both ubiquitous computing product evaluation processes ad development processes. Further, each of the quality characteristics has been expanded with evaluation questions and metrics, in some cases with measures. In addition, this quality model has been applied to the industrial setting of the ubiquitous computing environment. These have revealed that while the approach was sound, there are some parts to be more developed in the future

Legibility in typeface design for screen interfaces

This thesis explores the considerations related to the design of a typeface specifically for the use in interface typography. The genre of interface typefaces is outlined and essential attributes and requirements of this category of typefaces are inspected from the viewpoints of legibility, readability and type design practices. The research is based on the analysis of interface typeface samples, interviews with type designers as well as empirical findings documented by designers. These trade practices and design artefacts are contrasted with findings from cognitive psychology and legibility research. Furthermore the author’s design of the «Silta» typeface and its creation process are used to scrutinize and validate these observations. Amongst the crucial factors in the design of interface typefaces the legibility of confusable characters is extensively analysed. Furthermore, the rasterized on-screen rendering of outline based fonts is identified as a major contributing factor requiring special attention in the design, technical production and testing phases of modern fonts. Additionally, the context and use of interface typography and how users interact with interfaces are identified as the cornerstones influencing the design decisions of a typeface for this use. Finally, the aesthetics of interface typography and the motivations for developing specific interface typefaces are touched upon. As evident from the reviewed material, branding and visual identity often appear to be a driving force in the creation of new interface typefaces. However, the necessity for technological innovation and its demonstration equally inspire new design solutions. While technological limitations stemming from digital display media are increasingly becoming of less importance, the changes in reading behaviour and adaptive typography drive current development

Improving the translation environment for professional translators

When using computer-aided translation systems in a typical, professional translation workflow, there are several stages at which there is room for improvement. The SCATE (Smart Computer-Aided Translation Environment) project investigated several of these aspects, both from a human-computer interaction point of view, as well as from a purely technological side. This paper describes the SCATE research with respect to improved fuzzy matching, parallel treebanks, the integration of translation memories with machine translation, quality estimation, terminology extraction from comparable texts, the use of speech recognition in the translation process, and human computer interaction and interface design for the professional translation environment. For each of these topics, we describe the experiments we performed and the conclusions drawn, providing an overview of the highlights of the entire SCATE project

Agencia Canaria de Investigación, Innovación y Sociedad de la Información (TESIS2020010113).In recent years, the use of video call or video conference tools has not stopped increasing, and especially due to the COVID- 19 pandemic, the use of video calls increased in the educational and work spheres, but also in the family sphere, due to the risks of contagion in face-to-face meetings. Throughout the world, many older people are affected by hearing loss. Auditory functional diversity can make it difficult to enjoy video calls. Using automatic captions might help these people, but not all video calling tools offer this functionality, and some offer it in some languages. We developed an automatic conversation captioning tool using Automatic Speech Recognition and Speech to Text, using the free software tool Coqui STT. This automatic captioning tool is independent of the video call platform used and allows older adults or anyone with auditory functional diversity to enjoy video calls in a simple way. A transparent user interface was designed for our tool that overlays the video call window, and the tool allows us to easily change the text size, color, and background settings. It is also important to remember that many older people have visual functional diversity, so they could have problems reading the texts, thus it is important that each person can adapt the text to their needs. An analysis has been carried out that includes older people to analyze the benefits of the interface, as well as some configuration preferences, and a proposal to improve the way the text is displayed on the screen. Spanish and English were tested during the investigation, but the tool allows us to easily install dozens of new languages based on models trained for Coqui STT.Open Access funding provided thanks to the CRUE-CSIC agreement with Springer NatureCanary Islands Agency for Research, Innovation and Information Society of the Ministry of Economy, Knowledge and Employment and by the European Social Fund (ESF) Integrated Operational Program of the Canary Islands 2014–2020, Axis 3 Priority Topic 74 (85%)PERGAMEX ACTIVE project, Ref.

Towards an aspect weaving BPEL engine

This position paper proposes the use of dynamic aspects and the visitor design pattern to obtain a highly configurable and extensible BPEL engine. Using these two techniques, the core of this infrastructural software can be customised to meet new requirements and add features such as debugging, execution monitoring, or changing to another Web Service selection policy. Additionally, it can easily be extended to cope with customer-specific BPEL extensions. We propose the use of dynamic aspects not only on the engine itself but also on the workflow in order to tackle the problems of Web Service hot deployment and hot fixes to long running processes. In this way, composing aWeb Service "on-the-fly" means weaving its choreography interface into the workflow
