Designers still often create a specific user interface for every target platform they wish to support, which is time-consuming and error-prone. The need for a multi-platform user interface design approach that designers feel comfortable with increases as people expect their applications and data to go where they go. We present Gummy, a multi-platform(More)
When creating applications that should be available on multiple computing platforms, designers have to cope with different design tools and user interface toolkits. Incompatibilities between these design tools and toolkits make it hard to keep multi-device user interfaces consistent. This paper presents Jelly, a flexible design environment that can target a(More)
Storyboards are used in user-centred design (UCD) to clarify a scenario that describes the future use of a system. Although there are many styles of storyboarding, the graphical notation and language are very accessible for all team members of a multidisciplinary team. This papers describes how principles and techniques from comics can facilitate(More)
For the design and development of graphical user interfaces, designers have to take various guidelines, standards and target platform characteristics into account. This is often a hard and time consuming activity because guidelines are spread over multiple documents using different styles, and furthermore it requires considerable effort to verify whether a(More)
Currently, it is difficult for a designer to create user interfaces that are of high aesthetic quality for a continuously growing range of devices with varied screen sizes. Most existing approaches use abstractions that only support form based user interfaces. These user interfaces may be usable but are of low aesthetic quality. In this paper, we present a(More)
Professional video searchers typically have to search for particular video fragments in a vast video archive that contains many hours of video data. Without having the right video archive exploration tools, this is a difficult and time consuming task that induces hours of video skimming. We propose the video archive explorer, a video exploration tool that(More)
As social networks offer a vast amount of additional information to enrich standard learning algorithms, the most challenging part is extracting relevant information from networked data. Fraudulent behavior is imperceptibly concealed both in local and relational data, making it even harder to define useful input for prediction models. Starting from expert(More)
Multi-device user interface design mostly implies creating suitable interface for each targeted device, using a diverse set of design tools and toolkits. This is a time consuming activity, concerning a lot of repetitive design actions without support for reusing this effort in later designs. In this paper, we propose D-Macs: a design tool that allows(More)
Nowadays, there is a growing demand to design user interfaces that run on many devices. However, existing multi-device design approaches are not suitable for domain experts, whose input can be invaluable to come to a suitable user interface for a specific domain. Existing techniques often require the manipulation of high-level models and transformations(More)
