TL;DR: It is shown that contextual frames, as phenomenological abstractions of context, can help designers of context-aware systems systematically explore and model the relation of context with behavior and with technology supporting behavior.
Abstract: Tools for self-care of chronic conditions often do not fit the contexts in which self-care happens because the influence of context on self-care practices is unclear. We conducted a diary study with 15 adolescents with Type 1 Diabetes and their caregivers to understand how context affects self-care. We observed different contextual settings, which we call contextual frames, in which diabetes self-management varied depending on certain factors - physical activity, food, emotional state, insulin, people, and attitudes. The relative prevalence of these factors across contextual frames impacts self-care necessitating different types of support. We show that contextual frames, as phenomenological abstractions of context, can help designers of context-aware systems systematically explore and model the relation of context with behavior and with technology supporting behavior. Lastly, considering contextual frames as sensitizing concepts, we provide design direction for using context in technology design.

TL;DR: This work proposes a reusable context ontology model that is based on two levels: a generic level and a domain specific level and proposes an adaptation strategy to guarantee the adaptation of applications to context.
Abstract: With an increasing diversity of pervasive computing devices integrated in our surroundings and increasing mobility of both users and hardware, it is important for computer systems and applications to be context-aware. Lots of works have already been done in this direction on how to capture context data and how to carry it to the application. Among the remaining challenges are to create the intelligence to analyze the context information and deduce the meaning out of it, and to integrate it into applications. Our work focuses on these challenges by defining generic context storage and processing model and studying its impact on the application core. We propose a reusable context ontology model that is based on two levels: a generic level and a domain specific level. We also propose an adaptation strategy to guarantee the adaptation of applications to context. Our case study shows that our context model and application adaptation strategies provide promising service architecture

TL;DR: This work presents a contextual access architecture for personalization and recommendation of interactive multimedia content captured in an instrumented instrumented environment that takes into account context information, user preferences and presentation constraints in order to personalize the access experience, tailoring it to users' needs.
Abstract: Multimedia capture and context awareness are two relevant subjects in ubiquitous computing research. While the former results in large amounts of digital media (e.g., video, audio, slides, text comments) being automatically produced, the latter offers the proper means to integrate and access such content. By merging the two concepts, users may benefit from tools that allow them to retrieve, view and interact with the captured media artifacts. In this paper, we present a contextual access architecture for personalization and recommendation of interactive multimedia content captured in an instrumented ed- ucational environment. Our approach takes into account context information, user preferences and presentation constraints in order to personalize the access experience, tailoring it to users' needs.

TL;DR: The main objective of this paper is to investigate the construction collaboration tools along with the concepts of cloud computing and context-awareness, and proposes a fresh vision of construction industry integration and collaboration in an efficient way that will eventually maximize productivity and enhance the efficiency and effectiveness of the construction industry.
Abstract: The construction industry has been characterised by fragmentation, lack of integration and complexities in processes and activities. These characteristics could threaten the delivery of project objectives which could ultimately have a negative impact on construction project success. The construction industry is associated with numerous activities, processes, organisations and individuals. Improving the collaboration between the parties within the construction industry will enhance productivity whilst maximising efficiency and effectiveness. Providing the construction industry parties with access to accurate and up-to-date information along with efficient communications via a reliable, competent and appropriate network is frequently a challenge. The main objective of this paper is to investigate the construction collaboration tools along with the concepts of cloud computing and context-awareness. The findings in this research are based on a thorough review of the comprehensive literature on IT, computing and construction. Accordingly, this study presents and develops the concepts and potential of innovative collaborative tools, such as Context-Aware Cloud Computing Information Systems (CACCIS). Implementing CACCIS in the construction industry will facilitate the construction supply chain processes, relations and networks along with increasing the opportunities for enhancing competitive advantages. Firstly, it is hoped that this study will contribute to improvements in construction industry collaboration which could ultimately improve and enhance its competitive advantages. Secondly, it proposes a fresh vision of construction industry integration and, most significantly, collaboration in an efficient way that will eventually maximize productivity and enhance the efficiency and effectiveness of the construction industry.

TL;DR: A generic context acquisition engine which is capable of context capturing, composition and broadcasting is developed which is deployed on a mobile device and disseminated to various context aware applications running on the same device.
Abstract: Smart phones show increasing capabilities for context-aware applications. The development of such applications involves implementation of mechanisms for context acquisition and context adaptation. To facilitate efficient use of the device's resources and avoid monitoring the same context changes from multiple points, it is necessary that applications share the context acquisition mechanism. In this paper, we intend to develop a generic context acquisition engine which is capable of context capturing, composition and broadcasting. By deploying the engine on a mobile device, context changes are monitored from single point and disseminated to various context aware applications running on the same device. As a proof of concept, the context acquisition engine has been implemented on the Android platform.
