Web Services as Product Experience Augmenters and the Implications for Requirements Engineering: A Position Paper

There is currently little insight into what requirement engineering for web services is and in which context it will be carried out. In this position paper, we investigate requirements engineering for a special kind of web services, namely web services that are used to augment the perceived value of a primary service or product that is itself not a web service. We relate requirements engineering to a common enterprise architecture pattern and derive from this a number of research questions for further study

Keeping an eye on the UI design of Translation Memory: How do translators use the 'concordance' feature?

Motivation – To investigate the usefulness of sub- segment matching (Concordance feature) in a Translation Memory interface and translators' attitudes to new UI developments around such matching. Research approach – An explorative work-in- progress using eye tracking for translation conducted by professional translators, followed by an opinion survey. Findings/Design – The results suggest that the Concordance window is useful for checking terminology and context, but there is some evidence that the translators do not wish to have this feature turned on constantly. Research limitations/Implications – This is an initial work-in-progress study with a limited number of participants. Quantitative and qualitative results are presented. Originality/Value – This is the first empirical research of its kind. Translators are rarely, if ever, consulted about the UI of the tools they have to use. Take away message - The potential productivity and quality gain from sub-segment matches in Translation Memory is not fully realised and may be enhanced with improved UI design derived from focused research on user experience. Keywords Translation technology, Translation Memory (TM), user interface, sub-segment matching, concordance, eye tracking, user experienc

NASTRAN applications to aircraft propulsion systems

The use of NASTRAN in propulsion system structural integration analysis is described. Computer support programs for modeling, substructuring, and plotting analysis results are discussed. Requirements on interface information and data exchange by participants in a NASTRAN substructure analysis are given. Static and normal modes vibration analysis results are given with comparison to test and other analytical results

Social Interaction and Intergenerational Skill Transfer

We explore the relationship between educational attainment and social interaction using individual level data from the British National Child Development Study. To be specific, we analyze whether an intergenerational aspect to this relationship exists by examining the relationship between the educational attainment of children and the degree of formal social activity undertaken by their parents. In accordance with the existing literature, our results support a positive association between education and social interaction. Furthermore, our results suggest that children´s scores in reading, mathematics and vocabulary tests are positively associated with the extent of their parents´ formal social interaction. This relationship is robust to controlling for the degree of intra-family based social interaction and the social activities of the child

Apps and wearables for monitoring physical activity and sedentary behaviour: a qualitative systematic review protocol on barriers and facilitators

International audienceObjective: Monitoring of physical activity and sedentary behaviours by mobile phone applications (apps) and wearable technology (wearables) may improve these health behaviours. This systematic review aims to synthesise the qualitative literature on the barriers and facilitators of using apps and wearables for monitoring physical activity and/or sedentary behaviour in adults.Methods: This review protocol is registered in PROSPERO (CRD42017070194). Scientific databases including CINAHL Complete, MEDLINE, PsycINFO, SPORTDiscus, Cochrane Library and Scopus will be searched for relevant studies published from 1 January 2012 to the date the searches are conducted. Studies will be included if they incorporated adults who used an app or wearable for monitoring physical activity and/or sedentary behaviour; explored the barriers and/or facilitators of using an app and/or wearable; and were published in English. Following duplicate screening of titles and abstracts, full texts of potentially eligible papers will be screened to identify studies using qualitative approaches to explore barriers and facilitators of using apps and/or wearables for monitoring physical activity and/or sedentary behaviour. Discrepancies will be resolved through consensus or by consulting a third screener. Relevant excerpts (quotes and text) from the included papers will be extracted and analysed thematically. The Critical Appraisal Skills Programme Qualitative Research Checklist will be used to appraise included studies.Conclusion: The results of this work will be useful for those intending to monitor physical activity and/or sedentary behaviour using these technologies

Talking About Task Progress: Towards Integrating Task Planning and Dialog for Assistive Robotic Services

The use of service robots to assist ageing people in their own homes has the potential to allow people to maintain their independence, increasing their health and quality of life. In many assistive applications, robots perform tasks on people’s behalf that they are unable or unwilling to monitor directly. It is important that users be given useful and appropriate information about task progress. People being assisted in homes and other realworld environments are likely be engaged in other activities while they wait for a service, so information should also be presented in an appropriate, nonintrusive manner. This paper presents a human-robot interaction experiment investigatingwhat type of feedback people prefer in verbal updates by a service robot about distributed assistive services. People found feedback about time until task completion more useful than feedback about events in task progress or no feedback. We also discuss future research directions that involve giving non-expert users more input into the task planning process when delays or failures occur that necessitate replanning or modifying goals

A model for the control mode man-computer interface dialogue

A four stage model is presented for the control mode man-computer interface dialogue. It consists of context development, semantic development syntactic development, and command execution. Each stage is discussed in terms of the operator skill levels (naive, novice, competent, and expert) and pertinent human factors issues. These issues are human problem solving, human memory, and schemata. The execution stage is discussed in terms of the operators typing skills. This model provides an understanding of the human process in command mode activity for computer systems and a foundation for relating system characteristics to operator characteristics
