Smart environments aim to make the life of their inhabitants more comfortable by having context-aware systems continuously work together to assist people with their daily tasks. However, all too often these assistive technologies are naively or optimistically developed assuming that systems can always anticipate what users want. Furthermore, the more these smart systems grow in complexity, the more prone to failure they become. The overall goal of this paper is to define new concepts and methodologies for the development of more reliable smart applications, and propose middleware support to analyze failures in context-aware behavior, culminating in a software-based safeguard that improves robustness against unforeseen human interventions, exceptional circumstances and unexpected events.

In Ambient Intelligence (AmI) systems, the contextual information (time, location, available resources, people behavior, etc.) usually needs to be monitored and analyzed in order to offer pro-active and context-aware functionalities to end users. Therefore, the contextual information should conform to an information model that is commonly devised to capture the specific features of a concrete AmI system. Hence, the incorporation of new functionalities to an AmI system usually involves the modification of the associated information model, which may lead to compatibility and maintainability difficulties. Moreover, the data integration and interoperability at information level between different AmI systems can be limited by the availability of shared concepts in their respective information models. To overcome those problems, this paper presents an information model that can be adapted to the specific data requirements of many different AmI systems, and reused across them. The benefits of the proposal have been validated through the development of a Mobile Forensic Workspace (MFW) for disaster scenarios.

Self-management in smart environments increases dependability of applications, thereby decreasing maintenance costs thanks to the reduced need for user and expert intervention. We define what we call the “self-* properties” of a self-managing system, namely, self-healing, self-protection, self-awareness, self-organizing, self-synchronization and self-configuration, as well as a generic self-* process enabling these properties. We focus on the self-healing property and a scenario in this context, where the states of a smart environment application in a self-healing process as well as functional and non-functional system requirements are identified. Finally, we present metrics, allowing a quantitative evaluation of the proposed self-healing process.

Ubiquitous environments present a series of specific challenges which must be faced in order to obtain the full potential that this kind of environments can provide to assist human beings in many scenarios. Especially, it can be challenging to appropriately manage the context changes. This feature directly affects the availability of the services deployed in the system, among other quality features, and implies additional development efforts from software developers. Service replication models and techniques may help to improve service availability and strengthen the system, e.g., against node disconnections. However, it is necessary to provide SOA with self-adaptive capabilities in order to be able to address a highly dynamic environment, creating and deploying service replicas at run-time and on demand. In this work, an analysis of the main elements involved in the dynamic deployment of service replicas is presented and how they can be combined to provide a self-adaptive software architecture to properly support the software development and dynamic service deployment in ubiquitous environments.
In this paper we will demonstrate how a science fiction storyboard was used as a means for delivering and discussing future technology and design innovations. We present a case in which an illustrated storyboard exemplified the interactions of an experienced-centered technology design concept – a winter caretaking system for a smart city and two devices that could assist its citizens. In the science fiction introduced, the emphasis is on the experience-centered design approach, particularly experiences relating to nurture, sympathy and control.
Science Fiction Prototyping (SFP) has a lot of potential as a tool to help turn patents into innovative marketable products. The underlying assumption of this paper is that many patents from research institutions and corporations alike lie idle when it comes to their actual realization and commercialization as real products. The conceptual paper focuses on patents that are already application-centric and constitute a technology prototype. Despite technological foresight and trend analyses gaining increasing momentum and attention in theory and practice, we anticipate a lack of creativity and future context in opportunity identification following invention. Whereas traditional methods focus on product prototypes and technological foresight, context prototypes gain substantially less attention. The paper derives a conceptual framework that addresses this gap and introduces SFP as a tool to foster commercialization efforts and business innovation. Its contribution is threefold: We explore new ways of how to spot new capitalization opportunities on patents, suggest SFP as a strategic tool to provide a more structured way of creative thinking to seize future market opportunities and aim at supporting SFP as an increasingly sophisticated method in technology forecasting and future science.
With the ever accelerating advances in science and technology, it seems that almost any dream in the science fiction can become true. This paper discusses two topics that are closely related to our daily life; buildings and transportation. Although the paper was inspired by Science-Fiction Prototyping (SFP), rather than using a conventional story based approach I have adopted an essay-style to extrapolate forward my thoughts on current living conditions and trends of technology development, to explore various possibilities for future buildings and transportation For example, I present ideas for an intelligent building concept motivated by the behavior of sunflowers to improve the regulation of natural light and heat absorption in buildings. In addition, I have mused on a possible solution to current traffic congestion problems. The motivation for these ideas is to make our life more convenient and comfortable in the future.
One of humankinds oldest quests has been to find the ‘elixir of life’, a mythical potion that, would grant the drinker immortality (and preferably, eternal youth!). One of the most famous tales of a search for this fabled tonic was that of the first emperor of a unified China, Qin Shi Huang (246 BC. to 210 BC), who, in the latter part of his life, is said to have become preoccupied with finding this illusive concoction. This article is presented at a workshop that is taking place in the heartland of what was Qin Shi Huang's empire (China), and touches on a modern day search for an elixir of life, this time a high-tech approach based on computers and artificial intelligence technology, that goes by the name of ‘The Technological Singularity’. However, as fascinating as a search for an elixir of life may be, the real motivation of this paper is to introduce micro-fiction as a methodology for capturing and communicating visions for scientific, business and societal innovations. To those end, The Technological Singularity is described and used as a means to illustrate the workings of micro SciFi-Prototyping (micro-SFPs).
This paper describes the design of an adaptive intelligent augmented reality serious game which aims to foster problem solving skills in young learners. Studies show that our students lack computational thinking skills in high school, which raises the need to establish new methods to develop these skills in our younger learners. We believe that problem solving skills are the fundamental skills of computational thinking and are critical for STEM, in addition to a broad range of other fields. Therefore we decided to focus on those meta-cognitive skills acquired to foster problem solving, such as strategic knowledge. The game described in this paper provides a unique adaptive learning environment that aims to develop learners' meta-cognitive skills by utilizing augmented reality technology, believable pedagogical agents and intelligent tutoring modules. It offers a great user experience and entertainment which we hope will encourage learners to invest more time in the learning process. This paper describes the architecture and design of the game from the viewpoint of educational pedagogies and frameworks for serious game design.
Interaction between virtual and physical worlds is an area of growing importance as technology increases the amount of virtualization in our lives. However, to-date, most of this work has focused on translating the physical world into a virtual representation, with little attention being paid to instantiating the virtual in the physical world. This paper addresses this latter issue. In particular we examine how a virtual student can be given a presence in a real smart classroom in order to have better interaction with local students within a shared environment. In this ‘’work-in-progress' (concept) paper, we propose a novel augmented-reality based approach that identifies and synchronises the remote and local environmental states (people and environment) so as to provide a more naturalistic mixed reality shared environment.
The Paper is entitled “The Condition of Chinese Architecture: Elaboration of a critical approach.” The object of the research is the contemporary Chinese architecture. In short, the research consists of 3 sections: Nowadays reality, the contemporary architecture studied through the big numbers of its expansion, the size and quantity of projects, the issue of demolition-history, the relationship between the project and the context and the so-called “no context”, the explanation of numbers of the Chinese phenomenon and condition that determines its architecture and the will of the search for identity. Trends Panorama, they are divided between objects mega-structural, landmark buildings and buildings icons, traditional and vernacular architecture. Considerations, the opposite point of views of Rem Koolhaas and Yung Ho Chang, one focused on the understanding of the reality and the current situation in Asia and the other one defining a new type of architecture focused on the quality of the space and the against the formalism.
