With various connectivity and communication protocols, it is conceivable that all raw data from sensor devices can be made available in the Internet. However, this imposes a significant intricacy when dealing with the amount of information and the management of the devices. To alleviate the problem, this paper presents a design and implementation of a prototype IoT gateway framework that exposes high-level...
Complex adaptive systems are in the heart of smart city operations. Developing such systems is very challenging. Current user-driven techniques for modeling the system domain are not sufficient for supporting the development of such systems. Additionally, in the majority of cases, existing work focused on user interface adaptation without considering content personalization. In this paper, we propose...
The use of Information and Communication Technology (ICT) has touched various aspects in the domain of transport engineering and logistics (TEL). As the development of TEL tends to be more complex in operation and large in scale, recent practices start to pay more attentions on improving system robustness and reliability. In addition, current ICT innovations (such as WSN and IOT) could record and...
People use reminders to recall tasks to-do. But sophisticated enough tools are unavailable. Context-Awareness in mobile computing is more engaging area in gathering information about the user's current situation and would be ideal to integrate with the reminders to generate context-aware reminder where rich context is used to identify when a reminder should be presented to its recipient. Here we have...
Adapting application to diverse/dynamic domains is required to enlarge pervasive computing use, to satisfy people demand in terms of continuity of services. In addition, the proliferation of smart devices, ubiquitous services motivate the need for a quick development of applications that support people in dynamic domains. Inappropriately, this quick development is often associated a discard of domain...
The new Information, communication, and mobile technologies empower the users to learn anywhere and anytime. They also need conversational systems that could be aware of their mobile context in order to adjust it dynamically. The actual research field is focusing on adaptive conversational systems, especially in the case of Mobile-learning. This paper presents a comparative study of some related works...
Systems enabling smart city operations are highly adaptive complex systems that pose great challenges in their development and operation. Current user-driven techniques for system domain modeling and requirements engineering are not adequate for supporting the development of such systems. In this paper, we propose a development process and an environment-driven modeling approach for the Requirement...
Context-awareness plays an important role to offer an intelligence in terms of provision of user-centric features in Internet of Things (IoT). Web of Objects (WoO) has been introduced to support a framework to simplify application deployment, maintenance and operation of IoT service infrastructure by classifying and integrating objects on the World Wide Web. The semantic ontology is applied on a WoO...
Future Internet is foreseen to fully handle a wide range of multimedia services allowing their access trough diverse computing devices such as laptops, TVs, PDAs and 3G mobile phones interconnected via different wire-line and wireless networking technologies. Such a diversification in the computational context reinforces the need of personalized and adaptive media services towards better end-user...
Even though personal working processes run into business processes and access the same databases, human working processes and business processes in most cases are moving into opposite directions. Hence, individual knowledge and process-related knowledge are two aspects that are still very separated from each other. This leads to the result that most of the organizational knowledge base is not used...
In order to ensure accessibility of user interface, it is highly recommended to elaborate a generic solution which is compliant to disable user requirements and best accommodates their particular needs. Therefore, we propose, in this paper, a generic MDA-based solution of adapting application's interface to accessibility context. It consists of generating, automatically, accessible adapted User Interfaces...
Over the last decade, contextual modeling has gained on importance due to the wide spread introduction of ubiquitous and mobile computing. Common to these systems is that they integrate contextual information to improve situated cognition and awareness as well as stakeholders' usage experience with these systems. While domains such as the next generation of the Web - Web 3.0, which shares many commonalities...
With the growing production and access of resources managed by sensor-rich ubiquitous devices, such as photos, videos, and services, critical issues arise from access control point of view. Sensor-rich devices offer users new opportunities for creating, accessing, and sharing resources from anywhere and at anytime, interacting dynamically with other surrounding devices, users, and the environment...
The informational flow in modern technological systems is intensive due to multiple embedded devices, which leads to informational overload for users, causes time lost and decreases the reliability of the performance of a human-machine system. There is a need for efficient managing of information in order to display it to a particular user accordingly to his/her current needs. This paper presents...
Today smartphones and tablet PCs are gaining more popularity due to cutting edge technology added on top of wearability, thus creating the scene for context-aware applications that are capable to sense and actively use context to provide the user with valuable information whenever and wherever is needed, even while on the move. In this paper we describe CAPIM, a platform designed to support the construction...
Modern buildings are equipped with multiple systems, which are dedicated to improve quality of living for inhabitants and to facilitate performance of daily duties for maintenance personnel. Yet the variety of the systems causes the bulky informational flow, which may result informational tense to the user, time lost and increase of errors. To make life comfortable in a smart house, the inhabitants...
Automation industry is moving towards more complex systems which are posing new challenges for operation from both machine and human perspectives. A group of challenges is related to management of the overwhelming information flow and to usability of the systems, and context-aware solutions have been recently introduced to the automation field in order to cope with challenges of this kind. The context...
Advanced mobile devices increasingly provide innovative services and applications that can be accessed anywhere and anytime. The actual challenge is to take into account the dynamically changing conditions of the heterogeneous resources (equipments, data sources, services, etc) required for providing in ubiquitous environments an optimized, self-adaptive and personalized task management according...
This paper proposes a service automaton to proactively provide services to users in a context aware pervasive system. First, a context space (CSP) model is proposed based on conceptual space theory, and this model deals with context, situation, services and user preferences in a unified way. In CSP, situation is used to depict the specific scene faced by a user; user preferences can be deemed as a...
The intelligent home environment is a well-established example of the Ambient Intelligence application domain. A variety of sensors and actuators can be used to have the home environment adapt towards changing circumstances and user preferences. However, the complexity of how these intelligent home automation systems operate is often beyond the comprehension of non-technical users, and adding new...
