Modern research directions in smart environment include analysis of factors that influence overall human Quality of Life (QoL). Context influence factors (CIF) are unavoidable within smart environment research. In this paper, we address indoor air quality (IAQ) as one of the main CIF. The major contaminants of indoor air are CO2 and volatile organic compounds (VOCs). There are still no satisfactory...
The rise of pervasive computing presents unique opportunities due to increasing availability of smart devices such as mobile phones and tablets equipped with various sensors enabling Near Field Communication (NFC) technologies. The growth of mobile computing has led to an increase in access to digital music. With the growth of digital music, the development of music information sharing services for...
We describe an agent based approach to control a heterogeneous and dynamic device ensemble. The resulting controller provides pro-active assistance to the users of the environment. For this, roles defining the functionality are attached to dynamically constructed agents. Those roles are assigned based on the current situation, that is the accessible state of all devices and the currently assigned...
We present and discuss a context aware publish subscribe system. This allows for efficient communication between different components within distributed environments. For this we introduce context-awareness into the subscription handling. Our middleware allows to attach context properties to event subscriptions. Only if those properties are satisfied by the current state of the world, the events are...
Ambient intelligence (AmI) considers responsive environments in which applications and services adapt their behavior according to the user's needs and changing context. One of the most challenging aspects for many applications in AmI environments is location and orientation of the surrounding objects. This is especially important for effective cooperation among mobile physical objects in such smart...
Smart environment is defined here as a number of devices that can share information and services independently of their physical location. Smart environments based on ubiquitous computing open new possibilities to various aspects of human activities. The paper proposes an approach to emergency situation response that benefits of the ubiquitous computing. The approach is based on utilizing role profiles...
Smart environments are slowly but surely entering our everyday life. Their design provides many challenges. Not only heterogeneous devices acting and interacting in a dynamic environment but also intentions and activities of humans have to be taken into account. Diverse processes are responsible for achieving unobtrusive and pro-active user assistance. Those can be structured into a pipeline of perception,...
This work describes innovative smart environments with embedded context-awareness technologies, enabling new business models and consequently the creation of new services. The context-awareness framework presented in this paper is taken from the results of an EU Framework Programme (FP) 7 Information and Communications Technologies (ICT) project. Major novelties include a business shift from traditional...
In this paper we present the design of a decentralized vision-based object search system that can be used for elder care in a smart environment. In our approach, each autonomous search agent maintains separate estimates of the probability density function (PDF) of the object location and makes independent decisions about its search process. Asynchronous cooperative search is achieved by transmitting...
Mobile navigation service is one of the most important location based services. With the rapid advances in enabling technologies for ubiquitous computing, more and more active or passive devices/sensors are augmented in the indoor environment, indoor environment has become smarter. This paper proposes that by introducing the notions of smart environment and ambient intelligent, a ubiquitous indoor...
