In order to make optimal educational use of social spaces offered by thousands of international communities in the second generation web applications termed Web 2 or Social Web, ICT competences as well as social skills are needed for both teachers and learners. The paper outlines differences in competence structures of Net Natives (who came of age in the 21st century) and the Net Generation of ...

Young people’s interaction online is rapidly increasing, which enables new spaces for communication; the impact on learning, however, is not yet acknowledged in education. The aim of this exploratory case study is to scrutinize how students frame their interaction in social networking sites (SNS) in school practices and what that implies for educational language teaching and learning practices....

There is a need in emerging smart lighting concepts for a high-speed sensing capability to enable adaptive lighting (smart spaces) and visible light communication. One approach to address this need is to design and manufacture a novel complementary-metal–oxide– semiconductor (CMOS) compatible, cost-effective detector array and readout circuit (ROIC) that incorporates integrated waveguide detect...

Design of the physical environment is increasingly recognized as an important aid in caring for people with dementia. This article reviews the empirical research on design and dementia, including research concerning facility planning (relocation, respite and day care, special care units, group size), research on environmental attributes (noninstitutional character, sensory stimulation, lighting...

The first applications for smart environments targeted well-scoped spaces and appliances. These applications were strong drivers to advance Wireless Sensor Networks (WSN) and the Internet of Things (IoT). With the evolution of the technological base, more complex environments became the new targets. The concept of cooperating objects (CO) enables further advancement of IoT and helps to grasp th...

This paper presents a new data structure for light field rendering, which resembles a Star Trek holodeck in form and function. The grid on a holodeck section acts as a fourdimensional rendering target for a ray tracing algorithm, whose goal is to update an interactive display. A holodeck server coordinates separate ray evaluation and display processes, optimizing disk and memory usage. Holodeck...

The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...
