Combined People Position and Compass Detection for Context-aware Service Provision

2006

A novel technique is discussed for people identification and position sensing in augmented reality by the use of two cooperating technologies. People are provided with RFID tags for localization and context definition, and then visually investigated for identity checking and compass detection. The two technologies are discussed within an implementation of a case study dealing with context aware service provision for students in a campus.

Presenting the Past: A Framework for Facilitating the Externalization and Articulation of User Activities in Desktop Environment

2006

Work processes are conducted in various contexts and they involve different tasks, interruptions, activities and actions. In all of these, tacit knowledge plays a part. Some part of that tacit knowledge can be externalized and articulated by continuously monitoring the user’s activities. Because the desktop environment is an integral part of almost any office work context, we chart the demands the unstructured and discontinuous nature of work puts on the management of desktop working context. We discuss possibilities to augment the user’s awareness of his/her desktop working environment by providing a context-aware application that can act as a map-like resource for the user’s past activiti…

From information to conversation

2000

We support the calls from many commentators to include human interaction in the web, rather than as an extra outside the web. We suggest a generic model of awareness, and some specific interpretations: action-event couplings to call a receiver; general awareness of known others; and local awareness of all others. We then consider extensions to the web into mobile and domestic appliances, and suggest that an underlying awareness service will be needed there as much, or more than in classic desktop web access.

Bridging Sensing and Decision Making in Ambient Intelligence Environments

2009

Context-aware and Ambient Intelligence environments represent one of the emerging issues in the last decade. In such intelligent environments, information is gathered to provide, on one hand, autonomic and easy to manage applications, and, on the other, secured access controlled environments. Several approaches have been defined in the literature to describe context-aware application with techniques to capture and represent information related to a specified domain. However and to the best of our knowledge, none has questioned the reliability of the techniques used to extract meaningful knowledge needed for decision making especially if the information captured is of multimedia types (image…

Interactive evolution for cochlear implants fitting

2007

International audience; Cochlear implants are devices that become more and more sophisticated and adapted to the need of patients, but at the same time they become more and more difficult to parameterize. After a deaf patient has been surgically implanted, a specialised medical practitioner has to spend hours during months to precisely fit the implant to the patient. This process is a complex one implying two intertwined tasks: the practitioner has to tune the parameters of the device (optimisation) while the patient's brain needs to adapt to the new data he receives (learning). This paper presents a study that intends to make the implant more adaptable to environment (auditive ecology) and…

Semantic Trajectory Modeling for Dynamic Built Environments

2017

This paper presents a data model to capture moving and changing objects in the context of dynamic built environment. Building elements are subject to change which represents semantic trajectories crossing trajectories of users. These semantic trajectories in dynamics built environment permit to capture fine-grained activities and behaviors of users and objects. The data model is based on ontology and description logics to capture logic constraints on semantic trajectories.

Browsing the information highway while driving: three in-vehicle touch screen scrolling methods and driver distraction

2012

Distraction effects of three alternative touch screen scrolling methods for searching music tracks on a mobile device were studied in a driving simulation experiment with 24 participants. Page-bypage scrolling methods with Buttons or Swipe that better facilitate resumption of visual search following interruptions were expected to lead to more consistent in-vehicle glance durations and thus, on less severe distraction effects than Kinetic scrolling. As predicted, Kinetic scrolling induced decreased visual sampling efficiency and increased visual load compared to Swipe, increased experienced workload compared to both Buttons and Swipe, as well as decreased lane keeping accuracy compared to ba…

Lobsters and dolphins are adapted to aquatic life whereas the green woodpecker and the fly are adapted to aerial life. The way in which these organisms are constructed allows them to execute certain functions within certain environments. This is a first, simple definition of adaptation which describes:The evolutionary process of adjustment of an organism to its environment. This historical aspect will be discussed in subsequent chapters.The result of this process — the state of adaptation — or the form of an organism at a certain point in its history. This functional-structural aspect will be dealt with here.

Automating statistical diagrammatic representations with data characterization

2017

The search for an efficient method to enhance data cognition is especially important when managing data from multidimensional databases. Open data policies have dramatically increased not only the volume of data available to the public, but also the need to automate the translation of data into efficient graphical representations. Graphic automation involves producing an algorithm that necessarily contains inputs derived from the type of data. A set of rules are then applied to combine the input variables and produce a graphical representation. Automated systems, however, fail to provide an efficient graphical representation because they only consider either a one-dimensional characterizat…
