Nowadays, numerous journals and conferences have published articles related to context-aware systems, indicating many researchers' interest. Therefore, the goal of this paper is to review the works that were published in journals, suggest a new classification framework of context-aware systems, and explore each feature of classification framework. This paper is based on a literature review of context-aware systems from 2000 to 2007 using a keyword index and article title search. The classification framework is developed based on the architecture of context-aware systems, which consists of the following five layers: concept and research layer, network layer, middleware layer, application layer and user infrastructure layer. The articles are categorized based on the classification framework. This paper allows researchers to extract several lessons learned that are important for the implementation of context-aware systems.

The role of prototypes is well established in the field of HCI and Design. A lack of knowledge, however, about the fundamental nature of prototypes still exists. Researchers have attempted to identify different types of prototypes, such as low- vs. high-fidelity prototypes, but these attempts have centered on evaluation rather than support of design exploration. There have also been efforts to provide new ways of thinking about the activity of using prototypes, such as experience prototyping and paper prototyping, but these efforts do not provide a discourse for understanding fundamental characteristics of prototypes. In this article, we propose an anatomy of prototypes as a framework for prototype conceptualization. We view prototypes not only in their role in evaluation but also in their generative role in enabling designers to reflect on their design activities in exploring a design space. We base this framework on the findings of two case studies that reveal two key dimensions: prototypes as filters and prototypes as manifestations. We explain why these two dimensions are important and how this conceptual framework can benefit our field by establishing more solid and systematic knowledge about prototypes and prototyping.

This tutorial introduces strategies how the knowledge of people's and devices' proxemic relationships can be applied to interaction design. The goal is to inform the design of future proxemic-aware devices that -- similar to people's natural expectations and use of proxemics -- allow increasing connectivity and interaction possibilities when in proximity to people, other devices, or objects. Towards this goal, the tutorial introduces strategies how the fine-grained knowledge of proxemic relationships between entities can be exploited in interaction design for digital surfaces (e.g., large interactive displays, or portable tablets).

Sketchnoting is a form of visual note taking where people listen to, synthesize, and visualize ideas from a talk or other event using a combination of pictures, diagrams, and text. Little is known about the design space of this kind of visual note taking. With an eye towards informing the implementation of digital equivalents of sketchnoting, inking, and note taking, we introduce a classification of sketchnote styles and techniques, with a qualitative analysis of 103 sketchnotes, and situated in context with six semi-structured follow up interviews. Our findings distill core sketchnote components (content, layout, structuring elements, and visual styling) and dimensions of the sketchnote design space, classifying levels of conciseness, illustration, structure, personification, cohesion, and craftsmanship. We unpack strategies to address particular note taking challenges, for example dealing with constraints of live drawings, and discuss relevance for future digital inking tools, such as recomposition, styling, and design suggestions.

Sketchnote Components, Design Space Dimensions, and Strategies for Effective Visual Note Taking

Trace figures are contour drawings of people and objects that capture the essence of scenes without the visual noise of photos or other visual representations. Their focus and clarity make them ideal representations to illustrate designs or interaction techniques. In practice, creating those figures is a tedious task requiring advanced skills, even when creating the figures by tracing outlines based on photos. To mediate the process of creating trace figures, we introduce the open-source tool Esquisse. Informed by our taxonomy of 124 trace figures, Esquisse provides an innovative 3D model staging workflow, with specific interaction techniques that facilitate 3D staging through kinematic manipulation, anchor points and posture tracking. Our rendering algorithm (including stroboscopic rendering effects) creates vector-based trace figures of 3D scenes. We validated Esquisse with an experiment where participants created trace figures illustrating interaction techniques, and results show that participants quickly managed to use and appropriate the tool.

When designing novel user experiences, paper-pencil sketches can support the design thinking process and are valuable for communicating design ideas to others. This hands-on course will demonstrate how to integrate sketching into researchers' and interaction designers' everyday practice -- with a focus on applying the techniques to the design of novel user experiences. Participants will learn fundamental sketching strategies, apply these in practice during many hands-on exercises, and learn the various ways of using sketches as a tool when designing interactive systems.

In everyday life, our interactions with objects on real tables include how our fingertips feel those objects. In comparison, current digital interactive tables present a uniform touch surface that feels the same, regardless of what it presents visually. In this video, we demonstrate how tactile interaction can be used with digital tabletop surfaces. We present a simple and inexpensive device -- the Haptic Tabletop Puck -- that incorporates dynamic, interactive haptics into tabletop interaction. We created several applications that explore tactile feedback in the area of haptic information visualization, haptic graphical interfaces, and computer supported collaboration. In particular, we focus on how a person may interact with the friction, height, texture and malleability of digital objects.
