Being involved in the development of a high standing Web site without having the necessary amount of money, we came to the idea of creating a set of basic features that Web sites should inevitably have in order to meet customers quality basic expectations. The paper reports on the development of the methodology created to face the research question. The result is an innovative methodology calle...

In recent years, Internet banking has made dramatic progress across the world. In this paper, the nature and business rationale of Internet banking are briefly reviewed and analysed. Then a multiple regression model is proposed to study the relationship between electric connectivity (PC, Internet and Mobile) and customers’ adoption of Internet banking. Empirical results are obtained and analyse...

The paper discusses the use of computer interactive visualisations to develop a system that allows the sharing of a concept space for information discovering. The proposed system presents a 3D interactive visualisation using direct manipulation techniques to support a shared construct based in a structured description of a concept space as an extension of a semantic map. The system design is br...

The thesis of this paper is simple: that understanding both the construction and the interpretation of algebras is useful not only as a speciication technique for the implementation of interactive systems, but also as providing fundamental insights into the design and use of such systems in a general way. This is in contrast rstly to state-oriented speciication techniques like Z and VDM , which...

Object alignment is one of the basic operations in drawing programs. Current solutions provide mainly three ways for carrying out this operation: either by issuing an alignment command, or by using direct positioning with the help of gravity active points, or by making use of constraints. The first technique has limited functionality, and the other two may be mysterious for a novice. We describ...

The ability of educational applications to adapt to individual students has been a sought-after feature for more than a decade. The difficulty of developing this kind of software and the lack of adequate tools that facilitate this endeavor have hindered the participation of instructors and teachers in the elaboration of adaptive applications. In this paper we describe an authoring tool, ATLAS, ...

Information disclosure in games influences behavior by affecting the players’ beliefs about the state, as well as their higher-order beliefs. We first characterize the extent to which a designer can manipulate players’ beliefs by disclosing information. Building on this, our next results show that all optimal solutions to information design problems are made of an optimal private and of an opti...

The paper analyzes the ongoing urban transformation and delineates an underlying rationale which enables the comprehension of the current dual character of the Arab city with particular reference to the case of Eastern Province of Saudi Arabia. The re-reading of city form is mainly based on the critical interpretation of the mechanisms of urban morphology in relation to both global economic imp...

The term prototyping has in recent years become a buzzword in both research and practice of system design due to a number of claimed advantages of prototyping techniques over traditional specification techniques. In particular it is often stated that prototyping facilitates the users' involvement in the development process. But prototyping does not automatically imply active user involvement! T...

The manipulation of three dimensional (3D) objects is a task frequently needed in different computer applications, especially in the context of computeraided design (CAD). In a typical desktop computing environment the user however has no direct access to the 3D-object, and it has to be controlled and manipulated using interaction mechanisms with a limited number of degrees of freedom (DoFs). M...
