Esses três conceitos em conjunto abrangem aspectos relacionados a inclusão, à qualidade do uso das aplicações móveis e as emoções que os usuários têm quando interagem com essa aplicação. Sendo assim, a utilização destes aspectos em conjunto se torna importante para garantir a aceitação deste tipo de aplicação por Pessoas que possuem um determinado nível de Deficiência Visual. O uso de tecnologias como diretrizes, abordagens, heurísticas que integram a Acessibilidade, Usabilidade e UX durante as fases iniciais do desenvolvimento tornam-se um importante aliado para melhorar o design de aplicações móveis para as Pessoas com Deficiência Visual. Através de um Mapeamento Sistemático da Literatura (MSL) realizado nesta pesquisa, apenas uma tecnologia de design apresentou de forma unificada os conceitos de Acessibilidade, Usabilidade e UX em conjunto, de forma a auxiliar os designers. No entanto, esta tecnologia identificada possui como foco o design apenas de dispositivos híbridos (como Smart TV). Além disso, um estudo exploratório com Pessoas com Deficiência Visual utilizando diferentes aplicações foi realizado com o intuito de identificar quais problemas de Acessibilidade, Usabilidade e UX as Pessoas com Deficiência Visual enfrentam ao longo de sua interação com a aplicação móvel. A partir dos resultados do MSL e do estudo exploratório, foi proposta uma técnica chamada Usability, Accessibility and User eXperience Design Guidelines about Visual Impairment (UAUDG-VI), contendo diretrizes para auxiliar o design de aplicações móveis para Pessoas com Deficiência Visual com os conceitos de Acessibilidade, Usabilidade e UX de forma unificada. Foram realizados estudos experimentais com o propósito de analisar e avaliar a viabilidade de uso da técnica proposta, investigando se a mesma permite ou não projetar estes três conceitos de qualidade de forma conjunta durante a fase de design de aplicações móveis para Pessoas com Deficiência Visual. Os resultados indicaram que a técnica auxiliou os participantes a criarem protótipos de aplicações móveis, considerando a Acessibilidade, Usabilidade e UX para Pessoas com Deficiência Visual. Os resultados também sugerem oportunidades para aprimoramento, e avanços da técnica e próximas etapas para a integração da Acessibilidade, Usabilidade e no contexto de design de aplicações móveis.Abstract: Accessibility, Usability and User eXperience (UX) are software quality concepts that directly impact the use of mobile applications by users who have a disability, such as visual impairment. These three concepts together cover aspects related to inclusion, the quality of use of mobile applications and the emotions that users have when interacting with this application. Therefore, the use of these aspects together becomes important to guarantee the acceptance of this type of application by Visually Impaired People (VIP). The use of technologies such as guidelines, approaches, heuristics that integrate Accessibility, Usability and UX during the early stages of development becomes an important ally to improve the design of mobile applications for VIPs. Through a Systematic Mapping Study (SMS) carried out in this research, only one design technology presented in a unified way the concepts of Accessibility, Usability and UX together, in order to help designers. However, this identified technology is focused on the design of only hybrid devices (such as Smart TV). In addition, an exploratory study with VIPs using different applications was carried out in order to identify which Accessibility, Usability and UX problems the VIPs face during their interaction with the mobile application. Based on the results of the SMS and the exploratory study, a technique called Usability, Accessibility and User eXperience Design Guidelines on Visual Impairment (UAUDG-VI) was proposed, containing guidelines to help design mobile applications for VIPs with the aspects of Accessibility, Usability and UX in a unified way. Experimental studies were carried out with the purpose of analyzing and evaluating the feasibility of using the proposed technique, investigating whether or not it allows designing these three quality aspects together during the design phase of mobile applications for VIPs. The results indicated that the technique helped the participants to create prototypes of mobile applications, considering Accessibility, Usability and UX for VIPs. The results also suggest opportunities for improvement, and technical advances and next steps for the integration of Accessibility, Usability and in the context of mobile application design

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Service Futures, Proceedings of the fourth Service Design and Service Innovation Conference

ServDes2014 explores how Service Design is contributing to ‘Service Futures’ and how it is developing as a field of research and practice. We have witnessed how the concept and role of services in the economy and society have come a long way since its first definitions and studies. Services have moved from being a peripheral activity in a manufacturing - centred economy; to an engine for growth and society driven innovation. This transformation has been fully recognised with a flourishing of service innovation and service research studies aimed at deepening understanding; and at supporting the development of services both as a sector and as a concept. We suggest that Service Design is closely following this transformation. Starting from its initial focus on service interactions and experiences; Service Design research and practice have entered more strategic and transformational roles; dealing with issues of organisational change; system design; sustainability and social change; amongst others. Increasingly; Service Design is considering ways to integrate and collaborate with other service related disciplines. Also; questions are emerging on the future of this field; considering the growing areas of application and the expansion of the concept of service itself. ServDes2014 has brought these recent discussions and transformations to the fore and offered an ideal place to collectively reflect on and imagine that future. ServDes.2014 ran over three days: The first day was dedicated to practical explorations of Service Design with eight workshops led by both practitioners and academics; The second day was mostly focused on (long and short) papers presentations organised in three parallel sessions and two extra workshops; The third and final day was partly dedicated to papers presentation and came to an end with three parallel forums exploring the future of Service Design Research and Education and their relationship with Social Innovation. Working at the boundaries of Service Design; Digital and Social Innovation; the keynote speaker Dominic Campbell (Futuregov); projected novel spaces and responsibilities for Service Design in relation to complex societal transformational challenges; while Prof. Pelle Ehn (Malmö University); positioned it within a historical retrospective of Participatory Design in a constant search for more democratic (service) design practices. The conference was organised around five main themes which are reflected in the proceedings structure: Emerging Directions for Service Design; Design for Service Innovation and Transformation; Service Design and Implementation; Novel Service Design Frameworks and Tools; Service Design Across Organisations. Thanks to everyone who contributed and participated to this conference; and we look forward ServDes.2016 further developments and ideas

A COMPARISON BETWEEN MOTIVATIONS AND PERSONALITY TRAITS IN RELIGIOUS TOURISTS AND CRUISE SHIP TOURISTS

The purpose of this paper is to analyze the motivations and the personality traits that characterize tourists who choose religious travels versus cruises. Participating in the research were 683 Italian tourists (345 males and 338 females, age range 18–63 years); 483 who went to a pilgrimage travel and 200 who chose a cruise ship in the Mediterranean Sea. Both groups of tourists completed the Travel Motivation Scale and the Big Five Questionnaire. Results show that different motivations and personality traits characterize the different types of tourists and, further, that motivations for traveling are predicted by specific —some similar, other divergent— personality trait
