    Get PDF
    During the past few years the web has changed and something which has been developed primarily for desktop computers can now be accessed from everywhere using portable and mobile devices. However, these new devices have some serious limitations in terms of screen size and computational power, just to mention a few. In order to display web pages designed for desktop-sizes monitors, some small screen web browsers provide different approaches for this problem – however, these approaches have limitations. In this paper, we have performed tests to five different small screen rendering web-browsers (Pocket Internet Explorer, Minimo, NetFront, Opera, Opera Mini) while rendering some relevant web sites.info:eu-repo/semantics/acceptedVersio

    Designing Graphic Design History: Teaching for the 21st Century Classroom undertakes the development of a web-based Graphic Design History interactive timeline (GDHit), intended as a user-generated online database for potentially all graphic design enthusiasts, but specifically faculty and students within the traditional graphic design history course. GDHit seeks to continue the implementation of new media and emerging digital technologies in a traditional, lecture-oriented environment by inviting the user (or audience) to contribute the content for the timeline, while fostering new forms of course engagement for students in this digital age. In keeping with the tenets of the digital age and its inherent spirit of cross-disciplinary collaboration, the author engaged two computer scientists over the thesis development period (academic year 2010-2011). They developed the framework for how content is entered into and filtered within the database, as well as aiding with technical aspects of the interactive timeline

    In recent years there has been a growing interest into the use of multimedia mobile guides in museum environments. Mobile devices have the capabilities to detect the user context and to provide pieces of information suitable to help visitors discovering and following the logical and emotional connections that develop during the visit. In this scenario, location based services (LBS) currently represent an asset, and the choice of the technology to determine users' position, combined with the definition of methods that can effectively convey information, become key issues in the design process. In this work, we present MusA (Museum Assistant), a general framework for the development of multimedia interactive guides for mobile devices. Its main feature is a vision-based indoor positioning system that allows the provision of several LBS, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits according to visitors' personal interest and curiosity. Starting from the thorough description of the system architecture, the article presents the implementation of two mobile guides, developed to respectively address adults and children, and discusses the evaluation of the user experience and the visitors' appreciation of these application

    Testing Responsive Web Pages Using the Consistency of Automated Web Pages

    Get PDF
    The introduction of mobile devices with smaller screens motivates the need for web pages that work correctly across many different devices—referred to as responsive web design. Mobile access is a key feature for companies: both to reach new customers, and also to provide an enhanced service to existing customers. Testing the correct appearance of a responsive web page on different devices is not a trivial task because there are no standard rules for responsiveness, and the layout may need to be significantly rearranged in order to fit on smaller screens. This dissertation describes an investigation into the automated test case generation for responsive web pages. The aim of the project is to develop a novel approach to test responsive web pages for the consistency of their appearance. This thesis develops the idea of consistent web pages which are not identical but provide essentially the same interface to the user. The goal of this project is to develop approach on how to do automated test case generation of the appearance of responsive web page and to evaluate this approach by building a test tool that automate the testing of consistency of responsive web pages against the master copy of the page. Several rules were implemented for comparing web pages displayed on different screens. The results show that the approach taken is an effective way of automating testing for consistency. This dissertation also identifies a number of unanswered research issues to be addressed by future work

    Compact gml: merging mobile computing and mobile cartography

    Get PDF
    The use of portable devices is moving from "Wireless Applications", typically implemented as browsing-on-the-road, to "Mobile Computing", which aims to exploit increasing processing power of consumer devices. As users get connected with smartphones and PDAs, they look for geographic information and location-aware services. While browser-based approaches have been explored (using static images or graphics formats such as Mobile SVG), a data model tailored for local computation on mobile devices is still missing. This paper presents the Compact Geographic Markup Language (cGML) that enables design and development of specific purpose GIS applications for portable consumer devices where a cGML document can be used as a spatial query result as well

    Using Scrum in a side project with distributed teams

    Get PDF
    Scrum is the most popular agile software development methodology in use today (VersionOne, 2013), (West & Grant, 2010), (Begel & Nagappan, 2007). Many of the Scrum teams work in virtual distributed formations (VersionOne, 2013). The distributed work model introduces multiple burdens, like communication issues, matter of trust, time zones and cultural differences to the teams, which can severely affect performance (Deemer, s.a.). As a result, dislocated Scrum teams have a considerably lower success rate than collocated ones according to various surveys (Ambler S. W., 2008), (Ambler S. W., Agility at Scale Survey 2012, 2012), (Cohn, 2010). This paper researches the topic of “Using Scrum in a side project with distributed teams” and consist of three main parts: theoretical background, methods and results. In the theoretical background we cover the different software development methodologies, agile methodology in particular. We take a deeper look into Scrum; it's history, roles in Scrum, Scrum artifacts and ceremonies. We also briefly discuss virtual teams theory. In the methods we cover the online contract bridge card game development, Lean Startup and Business Model Generation as part of business development, background info on contract bridge, validating the idea, the design and development tools used to build the minimum viable product and the methods of data collection for Scrum. In the results we describe our implementation of Scrum, the building of the minimum viable product, and research made into other early stage startup teams to support our own findings.http://tartu.ester.ee/record=b2656166~S1*es

    iRead: An Application for enhanced reader navigation on e-reading tablet devices

    As the digital world is becoming more and more a part of people\u27s daily lives, the publishing industry has begun to evolve. The traditional print codex form of the book has been challenged by new technologies that have brought traditional books into the digital world--e-books. Reading has become evermore digital. Many of the current technologies for e-reading, whether it is the devices or the applications, are lacking navigation tools which limit the reader\u27s experience in comparison to reading a printed book. The goal of this thesis project was to design an application for reading e-books, to be used on tablet devices such as the iPad, focusing on solving the issues of user wayfinding and orientation for readers of all ages. To solve the problems of user wayfinding and orientation in e-reading applications research was focused on typography, book design, digital publishing and e-books, e-reading devices, and application design. All aspects related to books, both traditional and digital, as well as application design and user navigation were taken into consideration in order to come up with the most effective solution possible. A survey about e-reading applications was conducted to find out what readers would want when using an e-reading application. The project entailed three phases-graphic design, interactive design, and website design. A two column layout was developed to help users better understand what they were viewing as they navigated through the demonstration. The left column provides a project description and guides users through each section of the project. The project was broken down into four main sections-iPad, iRead, Library, and Book. The right column is a demonstration of the iRead application prototype where users can click on all icons, menus, and options to test how the application would work. I have designed iRead, a prototype for an e-reading application for the iPad. User testing proved the application prototype to be successful. The iRead application allows readers to navigate through an e-book in a manner that is parallel to that of reading a printed book

    Distributed D3: A web-based distributed data visualisation framework for Big Data

    Get PDF
    The influx of Big Data has created an ever-growing need for analytic tools targeting towards the acquisition of insights and knowledge from large datasets. Visual perception as a fundamental tool used by humans to retrieve information from the outside world around us has its unique ability to distinguish patterns pre-attentively. Visual analytics via data visualisations is therefore a very powerful tool and has become ever more important in this era. Data-Driven Documents (D3.js) is a versatile and popular web-based data visualisation library that has tended to be the standard toolkit for visualising data in recent years. However, the library is technically inherent and limited in capability by the single thread model of a single browser window in a single machine, and therefore not able to deal with large datasets. The main objective of this thesis is to overcome this limitation and address possible challenges by developing the Distributed D3 framework that employs distributed mechanism to enable the possibility of delivering web-based visualisations for large-scale data, which also allows to effectively utilise the graphical computational resources of the modern visualisation environments. As a result, the first contribution is that the integrated version of Distributed D3 framework has been developed for the Data Observatory. The work proves the concept of Distributed D3 is feasible in reality and also enables developers to collaborate on large-scale data visualisations by using it on the Data Observatory. The second contribution is that the Distributed D3 has been optimised by investigating the potential bottlenecks for large-scale data visualisation applications. The work finds the key performance bottlenecks of the framework and shows an improvement of the overall performance by 35.7% after optimisations, which improves the scalability and usability of Distributed D3 for large-scale data visualisation applications. The third contribution is that the generic version of Distributed D3 framework has been developed for the customised environments. The work improves the usability and flexibility of the framework and makes it ready to be published in the open-source community for further improvements and usages.Open Acces
