This paper presents the results of a case study examining prototyping as a method in re-designing a user interface (UI). In the case presented, a web-based room booking was re-designed. Running on a university web site, the existing system has caused much critique amongst its users. Their expectations for a new UI were increased ease of use, less effort required, and less time consumed. We prot...

User interfaces (UIs) are essential components of most software systems, and significantly affect the effectiveness of installed applications. In addition, UIs often represent a significant proportion of the code delivered by a development activity. However, despite this, there are no modelling languages and tools that support contract elaboration between UI developers and application developer...

Currently, user interfaces are defined by single applications but workflows may span multiple ones. In the result, users have to work with separated programs in parallel and deal with separated interfaces to fulfill their tasks. In desktop computing with extensive screens, working with several opened windows might not be eligible but bearable. For mobile devices with very restricted interaction...

In pursuit of the goal to make recorded speech as easy to skim as printed text, a variety of methods and user interfaces have been suggested in the literature, involving time-compressed audio, speech segmentation and recognition, etc. We propose a new user interface, the elastic audio slider, which makes navigation in speech documents similar to video navigation or text scrolling. The approach ...

In this work, we present a pen-based user interface (UI) that makes manual geometry decomposition easier and helps reduce user time spent on geometry decomposition for hexahedral meshing. This paper presents the first attempt to apply a pen-based UI for geometry preparation for mesh generation. The proposed UI is more natural, intuitive, and easier to use than existing interfaces such as Window...

Linked Data brings numerous RDF Knowledge Graphs to the Web, and as a result, the Linking Open Data (LOD) cloud comprises several independent – but linked – graph datasets. Faceted Browsing is a popular type of User Interface (UI) to explore the knowledge in these RDF graphs. Due to the distributed and linked nature of RDF graphs, exploring more than one graph at a time is a common interaction ...

With the help of rich web client technologies, developers are creating rich internet applications in response to end users' growing demand in richer web experiences. However, most of these technologies are fat client based. That is, to enable rich user interfaces, application code, whether binary or script, must be downloaded and executed on the client side. In this paper, we propose a thin cli...

A lot of research and work has been done in the past, to develop XML based user-interface definition languages. Also languages to describe graphics and animations were created. In an attempt to combine two of those languages with model-based user-interface generation, we demonstrate an idea of how a specific toolset, originally developed to support UI-Pattern based development, can be used to c...

This paper describes a design approach for creating generic computer user interfaces with spatial auditory displays. It proposes a structured depiction process from formulating mode independent descriptions of user interfaces (UIs), to audio rendering methods for virtual environments. As the key step in the process a semantic taxonomy of user interface content is proposed. Finding semantic clas...
