A brave new world of Ambient Intelligence in the casinos of Macau: reality or fiction?

The article scrutinizes the brave new world of ambient intelligence in the casinos of the Macau, Special Administrative Region of People´s Republic of China, chiefly in regards to the (candent) issue of privacy of the casino patrons. Moreover, this scientific article provides an overview about the secondary use of big data of the casino patrons for law enforcement purposes

An Opportunistic Reconfiguration Strategy for Environmentally Powered Devices

Environmental energy is becoming a feasible alternative to traditional energy sources for ultra low-power devices such as sensor nodes and smart watches. Moreover, the increas- ing need for exibility and recon gurability of such devices makes its energy management even more challenging. As a result, to e ciently exploit the potentially unlimited envi- ronmental energy, new adaptation strategies are required. In this paper we present a novel system recon guration strat- egy that exploits the intrinsic unpredictability of environ- mental energy to opportunistically recon gure the device. To assess the e ectiveness of the proposed recon guration strategy we rst perform a theoretical evaluation using sta- tistical energy pro le distribution and then we evaluate its energy e ciency on a prototype device in the presence of bursty energy pro les that we emulate using a programmable energy source

Wearable and Implantable Wireless Sensor Network Solutions for Healthcare Monitoring

Wireless sensor network (WSN) technologies are considered one of the key research areas in computer science and the healthcare application industries for improving the quality of life. The purpose of this paper is to provide a snapshot of current developments and future direction of research on wearable and implantable body area network systems for continuous monitoring of patients. This paper explains the important role of body sensor networks in medicine to minimize the need for caregivers and help the chronically ill and elderly people live an independent life, besides providing people with quality care. The paper provides several examples of state of the art technology together with the design considerations like unobtrusiveness, scalability, energy efficiency, security and also provides a comprehensive analysis of the various benefits and drawbacks of these systems. Although offering significant benefits, the field of wearable and implantable body sensor networks still faces major challenges and open research problems which are investigated and covered, along with some proposed solutions, in this paper

Application Domain-Driven System Design for Pervasive Video Processing

International audiencePervasive video processing in future Ambient Intelligence environments sets new challenges in embedded system design. In particular, very high performance requirements have to be combined with the constraints of deeply embedded systems, frequently changing operating modes, and low-cost, high-volume production. By leveraging upon the key properties of the application domain, we devised a computation model, a hardware template, and a programming approach which provide a natural mapping from application requirements to a complete system solution. Our approach enables the direct exploitation of concurrency and regularity in achieving the combined challenge of adaptability, performance, and efficiency
