Feedback is commonly used to explain what happened in an interface. What if questions, on the other hand, remain mostly unanswered. In this paper, we present the concept of enhanced widgets capable of visualizing their future state, which helps users to understand what will happen without committing to an action. We describe two approaches to extend GUI toolkits to support widget-level feedforward, and illustrate the usefulness of ...

Supershapes are used in Parametric Design to model, literally, thou-sands of natural and man-made shapes with a single 6 parameter formula. However, users are left to probe such a rich yet dense collection of supershapes using a set of independent 1-D sliders. Some of the formula’s parameters are non-linear in nature, making them particularly difficult to grasp with conventional 1-D sliders alone. VR appears as a promising setting for Parametric ...

Feedback and feedforward are two fundamental mechanisms that support users' activities while interacting with computing devices. While feedback can be easily solved by providing information to the users following the triggering of an action, feedforward is much more complex as it must provide information before an action is performed. For interactive applications where making a mistake has more impact than just reduced user comfort, correct ...

People often access the same information on a variety of devices such as laptops, mobile phones and tablet PCs. On every device, this information is accessed through a user interface that is speci cally designed for this device. Currently, designers have to create these multi-device user interfaces manually, which is time consuming and implies switching across a lot of di erent, often mutually exclusive, design tools. Furthermore, designers need ...

Adaptive Systems and Pervasive Computing change the face of computing and redefine the way people interact with the technology. Pioneers pursue a vision that technology is seamlessly situated in peoples life and adapts itself to the characteristics, requirements, and needs of the users and the environment without any distraction at the user side. Adaptive Systems research mostly focuses on individual applications that can alter their interface, ...

Purpose: Mashups have been studied extensively in the literature; nevertheless, the large body of work in this area focuses on service/data level integration and leaves UI level integration, hence UI mashups, almost unexplored. The latter generates digital environments in which participating sources exist as individual entities; member applications and data sources share the same graphical space particularly in the form of widgets. However, the ...

The mashup era has emerged in response to the challenge of integrating existing services, data sources, and tools to generate new applications. The mashups are usually realized either through a seamless integration, in which only the resulting application is known by the end-users, or through integration of original applications, data sources, and tools, particularly in terms of widgets, into the same graphical space, in which participating ...

This paper covers PaperPulse [3], a design and fabrication approach that enables designers to produce standalone interactive paper artifacts by augmenting them with electronics. With PaperPulse, users overlay visual designs with widgets provided in the design tool. PaperPulse provides different families of widgets, designed for smooth integration with paper, for a total of 20 different interactive components. We also contribute a demonstration ...

At Ghent University, we have built a course curriculum on integrated photonics, and in particular silicon photonics, based on interactive Jupyter Notebooks. This has been used in short workshops, specialization courses at PhD level, as well as the M.Sc. Photonics Engineering program at Ghent University and the Free University of Brussels. The course material teaches the concepts of on-chip waveguides, basic building blocks, circuits, the design ...

Education in architecture requires access to a broad range of learning materials, so as to develop flexibility and creativity in design. The learning material is comprised of textual and visual media including images, videos, descriptions of architectural concepts or projects, i.e. digital artifacts on different aggregation levels. Until now, repositories storing such information have not been interrelated and have not provided unified access. ...
