The past decade's computing revolution has delivered parallel hardware to the masses. However, the ability to exploit its capabilities and ignite scientific breakthrough at a proportionate level remains a challenge due to the lack of parallel programming expertise. Although different solutions have been proposed to facilitate harvesting the seeds of parallel computing, most target seasoned programmers...
Through the digitization of text corpora, information previously unavailable has become increasingly common. Among this information, the table of contents and index have been under-utilized for book search. This information can be represented visually, making it easier for the user to analyze the data efficiently and intuitively. By gradually narrowing in focus, from a large repository, to a few books,...
Brain-computer interface (BCI) systems enable humans to communicate with their environment by directly using brain signals. This way, body movement is not explicitly required for communication making this technology especially useful for people with limited mobility. In this study, the system performance and well-being of 38 subjects are investigated using two different layouts of graphical user interfaces...
The architectural Naked Objects Pattern is a promising approach for a rapid software development through productivity increase. Frameworks based on Naked Objects pattern were originally developed for the creation of sovereign posture applications, ie., where the user is treated as a problem solver. However much of the market applications are developed following a transient posture, where the user...
Most image and video retrieval tools used for large-scale media collections present query results as thumbnails arranged in a grid-like display with each thumbnail preserving the aspect ratio of its corresponding source image or video. Often, the outcome of a query is a set of thumbnails with different aspect ratios, thus a varying amount of padding space is used between the thumbnails in the display...
NETSPEAK helps writers in choosing words while writing a text. It checks for the commonness of phrases and allows for the retrieval of alternatives by means of wildcard queries. To support such queries, we implement a scalable retrieval engine, which returns high-quality results within milliseconds using a probabilistic retrieval strategy. The results are displayed as WORDGRAPH visualization or as...
Energy management systems employ a variety of schematic and quasi-geographic presentations in their user interfaces. These are sometimes generated automatically, but more often are hand-drawn and require considerable labor to create and maintain. Most of this labor goes into the arrangement, or `layout' of the power system elements within the overall diagram and when network models are exchanged,...
Meerkat is a tool for visualization and community mining of social networks. It is being developed to offer novel algorithms and functionality that other tools do not possess. Meerkat's features include navigation through graphical representations of networks, network querying and filtering, a multitude of graphical layout algorithms, community mining using recently developed algorithms, and dynamic...
Graphical user interfaces (GUIs) are fundamental part of software systems now days. This provides user with a facility to interact with the system. It is very important to clearly specify and precisely analyze GUI requirements before implementation of any system. Traditionally UML is considered as one of successful languages to model software requirements and specifications. But UML does not provide...
The paper presents WordnetLoom - a new version of an application supporting the development of the Polish wordnet called plWordNet. The primary user interface of WordnetLoom is a graph-based, graphical, active presentation of wordnet structure. Linguist can directly work on the structure of synsets linked by relation links. The new version is compared with the previous one in order to show the lines...
Intelligence analysts in the areas of defense and homeland security are now faced with the difficult problem of discerning the relevant details amidst massive data stores. We propose a component-based visualization architecture that is built specifically to encourage the flexible exploration of geospatial event databases. The proposed system is designed to deploy on a variety of display layouts, from...
Lasso selection tends to be inefficient in many circumstances such as selecting spatially large clusters. ICE-Lasso is a novel technique that infers likely target clusters during an ongoing lasso gesture. It provides efficient gesture-based interaction techniques as shortcuts to select partial, complete, and multiple clusters. Additionally, it is overloaded on the traditional lasso via automatic mode...
The popularity of blogs (as part of online social networking services) has grown dramatically in the last decade. Guided by ethnographic research of these online communities, we have designed a graphical interface for users' exploration and navigation of large scale blog network. In our design, we use the keyword based graph to help users for exploring the relationships in the large connected graph...
This study investigates empirically the use of five different interactive menu conditions: adaptable, adaptive split, adaptive/adaptable highlighted, adaptive/adaptable minimised and mixed-initiative menus. The aim of the study is to compare the usability of these five menus, with regard to task accomplishment time and frequency of error occurrence. It also aims to examine the effects of different...
The general notion of balance in visual design is apparent, but what is lacking is a more precise specification of how that balance is defined in concrete terms and achieved with specific design techniques, the exact location of the tipping point, as it were, between effective and overused colors, forms, and imagery. This paper will report results from an empirical study of restaurant menu design,...
Business Process Execution Language (BPEL) provides the capability of assembling business processes, it is the important technical foundation used by SOA for portfolio of services and service choreography, and developing BPEL business processes needs the support of visual modeling tools. Existing modeling tools are inadequate in supporting automatic layout in a graphical interface. When developing...
A brain-computer interface (BCI) provides the possibility to translate brain neural activity patterns into control commands for computers without user's movement. The brain activity is most commonly measured non-invasively via standard electroencephalographic (EEG) electrodes placed on the surface of the scalp. We propose the evaluation of the Bremen-BCI system based on steady-state visual evoked...
Visualizing large-scale online social network is a challenging yet essential task. This paper presents HiMap, a system that visualizes it by clustered graph via hierarchical grouping and summarization. HiMap employs a novel adaptive data loading technique to accurately control the visual density of each graph view, and along with the optimized layout algorithm and the two kinds of edge bundling methods,...
The modern social and cultural trend is that users themselves produce knowledge, participate in it, and share the knowledge. Under this circumstance, a new technology of visualizing information to help users have access to the knowledge easily and fast is attracting the industry's interest. The emergence of web 2.0 contents and social network service are good examples of such trend. In this paper,...
In this paper, a software framework and database system for biomedical image related to Chinese human genetic resources was proposed and implemented base on web database technique and SOA architecture. Firstly, the image characterization and storage implemented well with the conceived database system. Secondly, the customized imagery retrieval methods and the metadata retrieval approach were introduced...
