Automatic human Activity Recognition (AR) is an important process for the provision of context-aware services in smart spaces such as voice-controlled smart homes. In this paper, we present an on-line Activities of Daily Living (ADL) recognition method for automatic identification within homes in which multiple sensors, actuators and automation equipment coexist, including audio sensors. Three ...

The convergence of sensors, smart objects, wearable devices, communications (Internet, wireless, mobile), intelligent information processing (filtering, feature extraction, feature selection), and information fusion/detection technologies, has given birth to a new field of study and applications, called Internet of Things (IoT), Smart Planet, Cyber Physical Systems (CPS), Smart Sensing or 物联网 (...

Activity recognition in smart homes aims to infer the particular activities of the inhabitant, the aim being to monitor their activities and identify any abnormalities, especially for those living alone. In order for a smart home to support its inhabitant, the recognition system needs to learn from observations acquired through sensors. One question that often arises is which sensors are useful...

The Internet of Things (IoT) is the widely accepted technology that connect everyday objects to the internet for providing ease and various functionalities and the Smart Grid (SG) is defined as the power grid integrated with a large network of ICT. The SG is the combination of billions of smart objects: smart appliances, smart meters, actuators and sensors etc. This paper analyse the various ac...

Sensors (e.g., light, gyroscope, accelerometer) and sensing enabled applications on a smart device make the applications more user-friendly and efficient. However, the current permission-based sensor management systems of smart devices only focus on certain sensors and any App can get access to other sensors by just accessing the generic sensor API. In this way, attackers can exploit these sens...

INTRODUCTION In the last years, an increasing number of environments have been enhanced with smart sensors and have become more and more smart and self-organizing [1]. Situational awareness (SA) in these wide areas covers a huge range of topics and challenges [2]. As matter of fact, understanding activities for situation assessment cannot be achieved locally but it requires to widen as much as ...

In this article we critically discuss the challenge of integrating contextual information, in particular spatiotemporal contextual information, with human and technical sensor information, which we approach from a geospatial perspective. We start by highlighting the significance of context in general and spatiotemporal context in particular and introduce a smart city model of interactions betwe...

The study investigates the development of sensors, in particular the use of thermo-fluidic sensors and occupancy detectors, to achieve smart operation of air conditioning systems. Smart operation refers to the operation of air conditioners by the reinforcement of interaction to achieve both thermal comfort and energy efficiency. Sensors related to thermal comfort include those of temperature, h...
