As the vision of ubiquitous computing becomes reality, there is a possibility for user interfaces that follow the user through the physical world by jumping between local display devices. This paper presents previous attempts at this functionality and identifies their limitations. Justified by these limitations, we then present our novel method that uses new features of web-based technology. This...
Service Oriented Architectures (SOAs) are composed of distributed services that interact through standard interfaces, and evolve transparently to other services and users. Although such dynamicity makes SOA a promising architectural style, it prevents organizations from having complete knowledge of the SOA and of its (possibly untrusted) services. This constitutes an important restriction to the applicability...
Virtual Reality (VR) systems cannot be promoted for complex applications (involving the interpretation of massive and intricate databases) without creating natural and ”transparent” user interfaces: intuitive interfaces are required to bring non-expert users to use VR technologies. Many studies have been carried out on multimodal and collaborative systems in VR. Although these two aspects are usually...
Context-aware applications do not always adapt their behaviours in ways that users expect due to a variety of reasons. Applications that lack intelligibility are often incapable of offering explanations to users as to why they decided to adapt their behaviours in certain ways, and providing feedback mechanisms for users to take control of any unwanted adaptation. This can lead to loss of user trust,...
Recent rapid advancement in both pervasive mobile computing and cloud service has been driving numerous new applications in the ubiquitous media consumption. To provide mobile user with richer experiences, it is desired for the service providers to offer highly relevant recommendations of media content to the users by exploring user-user, user-media and user-context relationships. Furthermore, contemporary...
We have developed a new version of a pervasive system for monitoring and recording subjective pain experiences. The most important service the system offers to its users is real-time delivery of reported pain values from patients to nurses. Pain experiences are expressed on a six-value scale from "no pain" to "worst possible pain". The system was tested in four sessions with 23...
This paper presents an end-to-end framework to manage user-centric services through daily events. In contrast to existing service discovery, selection and composition approaches, the proposed framework addresses the management issue from a new perspective by firstly learning end-user's intent through daily events, while recommending relevant functionalities to the user; and then enabling the user...
Smart objects are gradually integrating into people's everyday life. While many context-aware solutions for pervasive computing environments do not consider users social aspects, we believe smart objects should be social-aware. So Smart aims at filling the gap in social understanding of the user environment, presenting an ontology based context model to support social context representation and automated...
Context-aware applications adapt their behavior to the user current situation. This paper presents a new architecture named COAST (Context-aware Speech to text translator). Reducing user interaction and selecting the best classifier based on contexts are the primary objectives in COAST and user's privacy rules can be applied too. The contexts are categorized in two sets: system-contexts and classification...
Geospatial technologies in conjunction with wireless grids will offer a context for locating and coordinating team activities in such a way that the nature of each team member's effort may be known and understood by other members. This constructed group knowledge enables teams to respond to unforeseen and emergent contingencies and act in concert through the active interpretation of shared artifacts...
The traditional techniques developed to deal with the issues in business process improvement don't meet the current and future organizations requirements. The existing methods are technology/fixed business process centric and not user-centric. The systems that can recognize the context of the user can bring great benefits especially enabling businesses to run more efficiently from any location. In...
In this paper, a sensing framework suited to intelligent vehicles design for automotive safety is presented. The extraction of the intrinsic parameters of the vehicle collected through the Controller Area Network serial bus (CANbus) is discussed and the implementation of a user interface for data visualization is shown. Algorithms for road lanes detection, vehicles detection and tracking and facial...
We present the first IDE augmented with static detection of inconsistent paths for simplifying the development and debugging of any application involving XPath expressions.
Research into users' resistance to an implemented system is one strand of work that examines users' responses to technology. In this paper, we investigate possible outcomes of user interactions with technology using the work of Louis and Sutton that indicates a wider range of possibilities than merely resistance. This is applied to the information systems context through the concept of appropriation...
This paper presents the results of a questionnaire on user behaviour during searching the Web as part of information gathering tasks. In this study, users' Web activities related to finding information, comparing information, managing information, and re-finding information, using different Web search and navigation tools, used for information gathering tasks are explored. The results indicate that...
The interfaces for human-machine interaction on a public telephone in Malaysian are symbolised by pictograms and icons. This paper attempts to illustrate the effectiveness of the “Phone Card Insert-Eject” pictogram in representing its intended function as an example to the overall study. Subsequently, a new set of pictograms were proposed and evaluated for its comprehension and...
This paper presents an analysis on a literature review findings in Interaction Design Issues Journals from the year 2006 to 2010. Due to the limited literature review reported on Interaction Design Issues, this study is aiming to provide some input on the current topics, methods and theories, interaction design elements and future trends of research in the field of Interaction Design. We employ content...
Smart environments are slowly but surely entering our everyday life. Their design provides many challenges. Not only heterogeneous devices acting and interacting in a dynamic environment but also intentions and activities of humans have to be taken into account. Diverse processes are responsible for achieving unobtrusive and pro-active user assistance. Those can be structured into a pipeline of perception,...
The topic of mobile services has piqued the interest of practitioners. Mobile service providers invest many resources to provide mobile services of higher quality in the hope of gaining more business opportunities and higher customer satisfaction. They often increase the service quality through the use of personalization, i.e., generating customized mobile content for each individual. Despite the...
The paper at hand introduces a new formal approach to user interface modeling. This approach is mainly motivated by a lack of formal methods for modeling interaction logic of interactive user interfaces. Based on formal methods, various verification, validation, transformation and reconfiguration techniques can be applied directly to user interfaces in the context of adaptation as well as usability...
