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.

Proxemic interaction is a vision of computing that employs proxemic relationships to mediate interaction between people and ensembles of various digital devices. In this chapter, we focus on aspects of peripheral interaction in proxemic interactions. We illustrate how to facilitate transitions between interaction outside the attentional field, the periphery, and the center of attention by means of the Proxemic Flow peripheral floor display. We summarize and generalize our findings into two design patterns: slow-motion feedback and gradual engagement. We propose slow-motion feedback as a way to draw attention to actions happening in the background and provide opportunities for intervention, while gradual engagement provides peripheral awareness of action possibilities and discoverability and reveals possible future interactions.

The ability of sensing breathing Is becoming an increasingly important function for technology that aims at supporting both psychological and physical wellbeing. We demonstrate ThermSense, a new breathing sensing platform based on smartphone technology and low-cost thermal camera, which allows a user to measure his/her breathing pattern in a contact-free manner. With the designed key functions of Thermal Voxel Integration-based breathing estimation and respiration variability spectrogram (RVS, bi-dimensional representation of breathing dynamics), the developed platform provides scalability and flexibility for gathering respiratory physiological measurements ubiquitously. The functionality could be used for a variety of applications from stress monitoring to respiration training.

The emerging Internet of Things (IoT), through which billions of everyday objects are becoming embedded with the abilities to sense their environment, compute data, and wirelessly connect to other devices, has been widely recognized as the new disruptive technology of our time. The predicted ubiquity of connected devices indicates that IoT technologies are quickly becoming an important part of the digital fluency curriculum, however, no research yet exists on suitable pedagogical approaches for teaching children about the IoT. The current research explores the design and deployment of a pedagogical approach and associated tangible toolkit, ConnectUs, that will enable 10-13 year old children to explore and design for the Internet of Things.

Many physical user interfaces are best viewed as an interacting collection of remotely-located distributed hardware and software components. The problem is that current physical user interface toolkits do not normally offer distributed systems capabilities, leaving developers with extra burdens such as device discovery and management, lowlevel hardware access, and networking. Our solution is Shared Phidgets, a toolkit for rapidly prototyping distributed physical interfaces. This toolkit offers programmers several ways to easily access remotely located hardware components, including a powerful distributed model-viewcontroller object model. Network communication and lowlevel access to the device hardware are transparently handled, regardless of device location. The programmer can also create new abstract devices by transforming and aggregating low level hardware device capabilities.

Sketchnoting is the process of creating a visual record with combined text and imagery of an event or presentation. Although analogue tools are still the most common method for sketchnoting, the use of digital tools is increasing. We conducted a study to better understand the current practices, techniques, compromises and opportunities of creating both penp trade-offs with flexibility; choice paradox and cognitive load; matters of perception, accuracy and texture; issues around confidence; and practicalities. We discuss those findings, the potential and limitations of different methods, and implications for the design of future digital sketchnoting tools.
