Couples in long-distance relationships (LDR) want to keep in touch, share emotions and feel connected despite the geographical distance. Current approaches to solve this problem include dedicated objects, common communication channels and mobile applications (apps). To combine the advantages of all three approaches, this paper introduces a hybrid approach(More)
Physical computing empowers people to design and customize electronic hardware tailored to their individual needs. This often involves "tinkering" with components connections, but due to the intangible nature of electricity, this can be difficult, especially for novices. We use a multistage design process to design, build and evaluate a physical prototyping(More)
We introduce StoryFaces, a new composition and storytelling tool for children to explore the role of emotional expressions in children's narrative. StoryFaces invites children to record emotional expressions that become part of storybook illustrations. As children watch the story being told, they see their faces bring the story to life; then they can "go(More)
In this paper we present <i>inTUIt</i> experience prototyping approach to investigate different simple identification techniques for tangible user interfaces (TUI) on digital surfaces. We have developed four different experience prototypes, proposing alternative approaches to the establishment of temporary ownership of digital content and TUIs in public(More)
We want to investigate the benefits of interactive surfaces for guiding novices in the learning process of physical computing. As interactive surfaces can augment physical objects with digital information, we utilize these to foster the learning experience in three ways: (1) by supporting multiple users for collaborative learning, (2) providing in-place(More)
User Experience (UX) is increasingly being recognized as an important factor for the commercial success of digital products. In fact, it has become a buzzword, which is interpreted differently by different parties. This lack of common understanding inevitably leads to misunderstandings and inefficiency in industrial practice. We therefore propose a(More)
We introduce <i>StoryFaces</i>, a new composition and storytelling tool for children to explore the role of emotional expressions in children's narrative. StoryFaces invites children to record emotional expressions and then automatically composes these recordings in storybook illustrations. After children watch their faces bring a story to life, they can(More)
WUENIC is a rule-based system implemented as a logic program, developed by WHO and UNICEF for estimating global, country by country, infant immunization coverage. It possesses many of the characteristics of rule-based legislation, facilitating decisions that are consistent, transparent and replicable. In this paper, we focus on knowledge representation and(More)
