Larger display surfaces are becoming increasingly available due to multi-monitor capability built into many systems, in addition to the rapid decrease in their costs. However, little is known about the performance benefits of using these larger surfaces compared to traditional single-monitor displays. In addition, it is not clear that current software designs and interaction techniques have been properly tuned for

Sensory innovation in the flavor industry is a pro- cess that relies heavily on user involvement to carry out critical sampling trials at a high cost. We are interested in how recommender systems, in par- ticular, have an important role to play in view of addressing some of their key challenges and con- straints. We describe a purpose-built sensory rec-

PLACE-Hampi provides a framework for a new approach to the rendering of the cultural experience, whose aesthetic and representational features gives the general public a dramatic new appreciation of the many layered significations of such historical, archaeological, and architectural spaces. While PLACE-Hampi embodies a single user interaction model, the autonomous narrative scenarios that populate each of the panoramic scenes with

In this paper, we introduce the concept of a transactional pattern for specifying flexible and reliable composite Web services. A transactional pattern is a convergence concept between workflow patterns and advanced transactional models; thus it combines workflow flexibility and transaction reliability. Designers can simply connect together transactional patterns to define a composite Web service. In relation, we provide techniques to ensure control and transactional consistency of such services.

Powerful computers and affordable digital media appliances result in a rapid growth of possibilities in the field of multimedia applications. There has been a significant increase in creation and use of multimedia content. Nowadays everybody can be treated as a potential creator and user of multimedia content. In order to deliver multimedia services to end-users, many parties are integrated and a series of Web services is accessed. A Web service in the composition can become unreachable by a number of circumstances, which requires run-time actions to replace it by another compatible Web service. A Web service can also perform less well than guaranteed, which also requires action in order to fulfill QoS requirements. To answer these requirements, we designed a broker middleware offering dynamic selection and composition of Multimedia Content Delivery services and automatic load balancing of these services over the available application servers. Since users want fast and reliable conn...

Automated segmentation of the esophagus in CT images is of high value to radiologists for oncological examinations of the mediastinum. It can serve as a guideline and prevent confusion with pathological tissue. However, segmentation is a challenging problem due to low contrast and versatile appearance of the esophagus. In this paper, a two step method is proposed which first finds the approximate shape using a "detect and connect" approach. A classifier is trained to find short segments of the esophagus which are approximated by an elliptical model. Recently developed techniques in discriminative learning and pruning of the search space enable a rapid detection of possible esophagus segments. Prior shape knowledge of the complete esophagus is modeled using a Markov chain framework, which allows efficient inferrence of the approximate shape from the detected candidate segments. In a refinement step, the surface of the detected shape is non-rigidly deformed to better fit the...

Figure 1: JECRIPE- a game for children with special needs Abtract There are not many initiatives in the area of game development for children with special needs, specially children with Down syndrome. The major purpose of our research is to promote cognitive development of disabled children in the context of inclusive education. In order to do so, we address aspects of interaction, communication and game design in stimulating selected cognitive abilities. By using a Human-Computer Interaction method based on the Inspection of Evaluation, it was possible to study and understand user interaction with the interface and thus examine the positive aspects as well as the communicability problems found with the JECRIPE game- a game developed specially for children with Down syndrome in pre-scholar age.

In this paper we discuss a new architecture to reduce unsolicited e-mail messages. We propose a system architecture that introduces two classes of messages-trusted e-mail and e-mail from untrusted sources. Trusted e-mail messages are signed with an S/MIME signature. To address usability problems that occurred previously with S/MIME signatures, outgoing e-mail messages are automatically signed on the e-mail server without

Online auction, shopping, electronic billing etc. all such types of application involves problems of fraudulent transactions. Online fraud occurrence and its detection is one of the challenging fields for web development and online phantom transaction. As no-secure specification of online frauds is in research database, so the techniques to evaluate and stop them are also in study. We are providing an approach with Hidden Markov Model (HMM) and mobile implicit authentication to find whether the user interacting online is a fraud or not. We propose a model based on these approaches to counter the occurred fraud and prevent the loss of the customer. Our technique is more parameterized than traditional approaches and so,chances of detecting legitimate user as a fraud will reduce.

Query formulation is a key aspect of information retrieval, contributing to both the efficiency and usability of many semantic applications. A number of query languages, such as SPARQL, have been developed for the Semantic Web; however, there are, as yet, few tools to support end users with respect to the creation and editing of semantic queries. In this paper we introduce a graphical tool for semantic query construction (NITELIGHT) that is based on the SPARQL query language specification. The tool supports end users by ...

Usage data logged from user interactions can be extremely valuable for evaluating software usability. However, instrumenting software to collect usage data is a time-intensive task that often requires technical expertise as well as an understanding of the usability issues to be explored. We have developed a new technique for software instrumentation that removes the need for programming. Interactive Usability Instrumentation (IUI) allows usability evaluators to work directly with a system's interface to specify what components ...

The lack of realistic and interactive use in social media applications is the main problem. We will try to solve it by using Augmented Reality. An innovation in development, Augmented Reality is a new sort of technology that superimposes virtual objects into "Reality" by use of a smartphone, optical device, or tablet screen. We will be using this technology to make application, which will be used as a replacement for traditional text based social and data sharing applications. People are using Social media, forums and other communication Medias tremendously from past few years. We noticed that all such applications and resources are basically in text format and this trend is followed by all the applications until now. Using Augmented Reality in such cases will change the definition of such media applications. That is why we decided to follow this concept and make a project using it. This Paper is about file sharing, information sharing and social media. Which will drive daily life of people with AR integrated experience. It is one-step ahead towards Hyper Reality, which can be used for private as well as public purpose. Augmented Reality (AR) will make things more realistic and interactive.

Le domaine du luxe est indiscutablement dépendant de comment la marque est perçue par ces clients. Les entreprises de ce milieu sont généralement des entreprises avec des démarches centrées utilisateur, ce qui veut dire qu’elles prennent en compte des données parvenues lors de l’analyse des consommateurs dans leur processus de conception, cela pouvant être même à travers leur participation dans des phases de créativité ou d'évaluation de concept. Il existe aussi d'autres profils dans ce domaine, des entreprises de luxe avec des démarches plutôt centrées nouvelles technologies. Ces entreprises intègrent des dimensions liées aux utilisateurs dans leur processus d'innovation de produits de manière intuitive, par des analogies sur leurs expériences passées avec des produits lancés ou en observant la concurrence et les réactions du marché (nombre de ventes, retour consommateurs, etc.). L'étude proposée dans cet article est focalisée sur les entreprises de produits de luxe dites "centrées nouvelles technologies". Cette étude est menée autour de l'intégration de méthodes centrées utilisateur dans les phases amont des processus d'innovation de produits pour la proposition de nouveaux concepts ou pour estimer la pertinence des concepts existants, à travers de l'analyse de l'interaction entre utilisateur et produit.
