Determination and evaluation of web accessibility
The Web is the most pervasive collaborative
technology in widespread use today; however,
access to the web and its many applications cannot
be taken for granted. Web accessibility encompasses
a variety of concerns ranging from societal,
political, and economic to individual, physical, and
intellectual through to the purely technical. Thus,
there are many perspectives from which web
accessibility can be understood and evaluated. In
order to discuss these concerns and to gain a better
understanding of web accessibility, an accessibility
framework is proposed using as its base a layered
evaluation framework from Computer Supported
Co-operative Work research and the ISO standard,
ISO/IEC 9126 on software quality. The former is
employed in recognition of the collaborative nature
of the web and its importance in facilitating
communication. The latter is employed to refine and
extend the technical issues and to highlight the need
for considering accessibility from the viewpoint of
the web developer and maintainer as well as the web
user. A technically inaccessible web is unlikely to be
evolved over time. A final goal of the accessibility
framework is to provide web developers and
maintainers with a practical basis for considering
web accessibility through the development of a set of
accessibility factors associated with each identified
layer
Usability dimensions in collaborative GIS
Collaborative GIS requires careful consideration of the Human-Computer Interaction (HCI) and Usability aspects, given the variety of users that are expected to use these systems, and the need to ensure that users will find the system effective, efficient, and enjoyable. The chapter explains the link between collaborative GIS and usability engineering/HCI studies. The integration of usability considerations into collaborative GIS is demonstrated in two case studies of Web-based GIS implementation. In the first, the process of digitising an area on Web-based GIS is improved to enhance the user's experience, and to allow interaction over narrowband Internet connections. In the second, server-side rendering of 3D scenes allows users who are not equipped with powerful computers to request sophisticated visualisation without the need to download complex software. The chapter concludes by emphasising the need to understand the users' context and conditions within any collaborative GIS project. © 2006, Idea Group Inc
Designing an interface for a digital movie browsing system in the film studies domain
This article explains our work in designing an interface for a digital movie browsing system in the specific application context of film studies. The development of MOVIEBROWSER2 follows some general design guidelines based on an earlier user study with film studies students at Dublin City University. These design guidelines have been used as an input to the MOVIEBROWSER2 system design. The rationale for the interface design decisions has been elaborated. An experiment has been carried out among film studies student, together with a one-semester trial deployment. The results show positive feedback and a better performance in the studentsâ essay outcome with higher perceived satisfaction level
COMMONALITIES AND CONTRASTS: AN INVESTIGATION OF ERP USABILITY IN A COMPARATIVE USER STUDY
In recent years, several user studies have examined specific usability problems in the field of Enterprise Resource Planning (ERP). These studies focused on different branches, various usability aspects, and several user groups. In spite of this diversification, some common and essential usability problems have become apparent, which are related to system complexity and difficulties in finding required information. However, these findings are based on the situation in a specific country, a singular ERP system and few data samples. Therefore, this paper aims at complementing the related work by results from a comparative user survey from two different European countries: Germany and Latvia. The survey is based on 184 ERP users from Germany and 24 ERP users from Latvia. The results indicated that both countries have several contrasts, but also diverse commonalities in industry, ERP market and culture. However, users in both countries are very homogenous with regard to the assessment of usability problems in their ERP interfaces. This paper investigates elementary usability problems derived from the related work and examines to which extent they are valid in both countries today. The main hypothesis claims that diverse national characteristics do not necessarily lead to a different assessment of usability problems in ERP systems
Enterprise Experience into the Integration of Human-Centered Design and Kanban
he integration of Human-Centered Design (HCD) and Agile Software Development (ASD) promises the
development of competitive products comprising a good User Experience (UX). This study has investigated
the integration of HCD and Kanban with the aim to gain industrial experiences in a real world context. A
case study showed that requirements flow into the development process in a structured manner by adding a
design board. To this end, the transparency concerning recurring requirements increased. We contribute to
the body of knowledge of software development by providing practical insights into Human-Centered Agile
Development (HCAD). On one hand, it is shown that the integration of HCD and Kanban leads to a product
with a good UX and makes the development process more human-centered. On the other hand, we conclude
that a cross-functional collaboration speeds up product development.Ministerio de EconomĂa y Competitividad TIN2013-46928-C3-3-RMinisterio de EconomĂa y Competitividad TIN2015-71938-RED
