“…The SCOUT framework by Woensel et al [9], aimed at easing the development of context-aware mobile applications, shares several similarities with our approach. However they specifically focus on the concept of nearby entities in the user environment, which can be discovered to provide relevant information and services to them.…”

Mobile phones enable us to carry out a wider range of tasks every day, and as a result they have become more ubiquitous than ever. However, they are still more limited in terms of processing power and interaction capabilities than traditional computers, and the often distracting and time-constricted scenarios in which we use them do not help in alleviating these limitations. Context-awareness is a valuable technique to address these issues, as it enables to adapt application behaviour to each situation. In this paper we present a context management infrastructure for mobile environments, aimed at controlling context information life-cycle in this kind of scenarios, with the main goal of enabling application and services to adapt their behaviour to better meet end-user needs. This infrastructure relies on semantic technologies and open standards to improve interoperability, and is based on a central element, the context manager. This element acts as a central context repository and takes most of the computational burden derived from dealing with this kind of information, thus relieving from these tasks to more resource-scarce devices in the system.

“…Besides research projects, there exist also a variety of application that are used for gathering information about context from mobile devices, like SDCF [5], AWARE 1 , JCAF [7], SCOUT [33], ContextDriod [32], Gimbal 2 . These are mostly concerned with low-level context data acquisition from sensors, suitable fur further context identification.…”

Abstract. Research in the area of context-awareness has recently been revolutionized by the rapid development of mobile devices like smart phones and tablets, which became omnipresent in daily human life. Such devices are valuable sources of information about their user location, physical and social activity, profiles and habits, etc. However, the information that can be obtained is not limited to the hardware sensors that the device is equipped with, but can be extended to every sensor that is available in a communication range of a device. Although the concept of multiple sensors and devices, exchanging information and working together as one big pervasive system is not new, there is still a lot of research that has to be done to allow building such systems efficiently. In this paper the prototype of a rule-based inference engine for mobile devices is described and evaluated. The most important challenges connected with migration from desktop to mobile environment were defined, and a comparison of Prolog-based platforms, as a portable environments for mobile context-aware systems were presented. We consider implementation using a portable Prolog compiler on Android platform.

“…Semantic Context-aware Ubiquitous Scout (SCOUT) (Woensel et al, 2009) is a framework for building context-sensitive applications for mobile devices. SCOUT allows mapping real world entities (e.g., people, places, objects) into virtual entities on the Web, so that the resources/services provided by these entities become location-specific and accessible when users are close to them.…”
