- Accessibility Solutions for Visually Impaired Persons: A Digital Platform ConceptualizationPublication . Oliveira, Rita; Prata, Alcina; Miranda, José Carlos; Abreu, Jorge Ferraz de; Almeida, Ana MargaridaThis chapter aims to address a study in which it is intended to conceptualize, develop, and evaluate an aggregation platform of accessible solutions target to Portuguese people with visual impairment, incorporating not only an information layer but also a training layer using, for example, explanatory videos and tutorials. The platform contents will be nourished through a logic of volunteering and be available through an interactive television (iTV) application and a web/mobile application accessible to visually impaired users. In this chapter, a state-of-the-art survey is made to identify types of digital solutions target to visually impaired users. Based on this survey, an analysis is made to understand what features and functionalities the proposed platform can integrate and how it can become a powerful solution for people with visual impairment. In addition to the state-of-the-art survey and its analysis, the chapter includes the identification and description of the system architecture that will support the proposed platform.
- Comparative WebGIS Software Study: How to Support Users Decisions on the Best Solution to Their OrganizationsPublication . Ventura, Sandra; Prata, AlcinaThe rapid evolution of information and communication technologies (ICT) has supported many changes in many areas over the last decade. One of the most successful ICT technologies to emerge was geographic information systems (GIS). These systems allow people to see the world differently, mapping the position and quantity of things, mapping the density of people and objects, and mapping any changes that occur. GIS also allows us to find out what is happening within a specific area or nearby. They can be used in various ways and across diverse areas thus becoming an important area of research. Regarding this chapter, the advantages and disadvantages involved in the use of GIS, especially WebGis or geoportals, were explored and presented, as well as a detailed comparative study in what concers to the main WebGis software solutions in terms of characteristics and functionalities. The main goal of the chapter was to provide users with a list of important recommendations that could help them in the process of choosing a WebGIS software, both in terms of free and proprietary solutions.
- Interactive TV as Part of Crossmedia Systems in Order to Enhance Informal Learning: The eiTV Case StudyPublication . Prata, Alcina; Chambel, TeresaCrossmedia systems are becoming the trend due to technological advances, better interfaces design, and changes in user habits. Due to the use of different devices as part of the same crossmedia system, which allow supporting a multiplicity of contexts of use, useful when considering learning scenarios, new research opportunities and challenges have arisen in the design of these systems. This chapter addresses the effective design of crossmedia systems and interfaces with a particular emphasis on iTV, PC, and mobile devices, through the eiTV application, designed and developed to illustrate and explore this paradigm, based on cognitive and affective aspects that influence user experience. The eiTV application is capable to create, access, and share personalized informal learning environments (created as additional information to the video being watched), via iTV, PC, and mobile devices (the preferred or most adequate device in each context of use).
