The boom of portable electronics and high-speed wireless networks has brought changes throughout society, including the style of teaching in schools. Modern technologies can, substitute the teacher in the process of teaching to a large extent. Thanks to possibilities of personalization and contextual of current device software equipment it is possible to take into account the individual needs of each...
As mobile devices increasingly incorporate a range of sensors, there is significant potential to apply opportunistic sensing techniques to allow collections of these devices to provide context information to applications. Focussing on a use case involving the use of mobile devices to sense and localize increasing levels of gases in a work environment, we show that the use of application-specific state...
Energy efficient building refers to building with an integrated system that is aware toward energy usage and has an effort to automatically reduce all electrical energy wasting by turning some unused devices off. In order to decide an appropriate decision, such a system needs surrounding contexts, such as location and activity that are obtained from sensors around the environment. We propose a novel...
Map services help people find places they wish to visit. Users input the target address and the system returns that location on a map, with additional information such as nearby points of interest, directions to the location, etc. However, these applications mainly focus on general knowledge, failing to provide personalized information that may help users find/identify a place faster. In this paper,...
“SeMoDesk” is an approach to implement the Semantic Desktop on mobile devices. The idea is to allow users to manage their personal information space using personal ontologies. In this paper, we are presenting our solution to improve location-awareness in this scenario. We have designed a location and sensor ontology as an extension to the personal ontology. This ontology is then used to retrieve relevant...
Ubiquitous computing has gained momentum over the last years with the expansion of mobile devices. One area of pervasive computing is context-aware systems which are applications designed to react to the constant changes in the environment. This paper presents a context aware platform that handles context acquiring, processing and service provisioning management. The platform alleviates the process...
