Article
Ambient Intelligence (AmI) focuses on creating environments capable of proactively and transparently adapting to users and their activities. Traditionally, AmI focused on the availability of computational devices, the pervasiveness of networked environments, and means to interact with users. In this paper, we propose a renewed AmI architecture that...
Conference Paper
This paper introduces a novel system to enhance the spatio-temporal alignment of human abilities in agent-based workflows. This optimization is realized through the application of Linked Data and Semantic Web technologies and the system makes use of gaze data and contextual information. The showcased prototype demonstrates the feasibility of implem...
Article
Head-mounted Augmented Reality (AR) displays overlay digital information on physical objects. Through eye tracking, they provide insights into user attention, intentions, and activities, and allow novel interaction methods based on this information. However, in physical environments, the implications of using gaze-enabled AR for human activity reco...
Article
The increasing number of objects in ubiquitous computing environments creates a need for effective object detection and identification mechanisms that permit users to intuitively initiate interactions with these objects. While multiple approaches to such object detection -- including through visual object detection, fiducial markers, relative local...

Head-mounted Augmented Reality (AR) displays overlay digital information on physical objects. Through eye tracking, they allow novel interaction methods and provide insights into user attention, intentions, and activities. However, only few studies have used gaze-enabled AR displays for human activity recognition (HAR). In an experimental study, we...

Terms of use of a digital service are often framed in a binary way: Either one agrees to the service provider's data processing practices, and is granted access to the service, or one does not, and is denied the service. Many scholars have lamented these ‘take-it-or-leave-it’ situations, as this goes against the ideals of data protection law. To ad...

Conference Paper
The industrial domain offers a high degree of standardization, a variety of very specialized use cases, and an abundance of resources. These characteristics provide perfect conditions for Digital Companion systems. A Digital Companion is a cognitive agent that assists human users by taking on three roles: as guardians, assistants or mentors, and pa...

Mobile technologies have increased the interest of industry and academia in providing users with information and services anytime and anywhere. Some services are customized according to the users’ characteristics, attempting to create ubiquitous environments that enable such users to share and discover resources. However, research that addresses th...
Article
A Contextual Graph is based on the Contextual Graph formalism, which allows experts to realistically model the possible ways a task can be realized (i.e., practices). The power of Contextual-Graphs relies on their capability of considering the situation-dependent data (i.e., contextual information) that characterizes a task realization. Through suc...
Article
Semantic applications can help commercial applications perform quickly and reliably by improving ecosystem interoperability. Converting and integrating current standards specifications to OWL models could support the adoption of semantic models, as well as machine-processable standards compliance and data interoperability.
Conference Paper
Semantic technologies are a powerful tool able to give meaning to flat data by creating ontologies that link information systems that live separately, but which complement each other in order to provide a common understanding of a domain. However, these technologies are also often seen as difficult to profit from due to their limited availability t...
Conference Paper
Full-text available
Humans and machines work closer together as never before. Whether it is about sensors to expand humans' sensorium, exo-skeletons augmenting physical capabilities, augmented and digital worlds breaking with physical boundaries, or curated digital memories: the value of all these technologies rises and falls with their ability to synchronize with the...
Conference Paper
Full-text available
In a vast range of domains, decision makers have taken advantages of the benefits of the Contextual-Graph (CxG) formalism for representing the way(s) an actor(s) executes a real-world task. For this purpose, the CxG software formalism provides actors with edition tools that help them create and explore contextual graphs in an intuitive manner. Howe...
Conference Paper
Full-text available
Through successfully applying the Contextual-Graph formalism in many fields (e.g. medicine, transport, and military), the need for an alternative visualization was recurrently encountered. Decision makers require: (1) a visual representation that clusters all the contextual information needed to develop a practice, and (2) a representation that all...
Conference Paper
Full-text available
The Contextual-Graphs formalism has been conceived to represent task realizations in the way they are actually performed. The objective is to provide decision makers with a clear panorama of the different ways a task can be realized (i.e. practices), and the implications of choosing one way or another. The Contextual-Graphs formalism has been succe...
Conference Paper
The current available technologies have not been fully exploited to assist collaborators to perform activities that are considered as time/effort wasting and tedious, but which cannot be omitted. A person working in an organization can be in need of a resource they do not own at any moment, but in a place consisting of multiple buildings that are f...
Article
Most of the semantic matchmaking algorithms have been developed for the search of Web Services, since there is a huge need for tools that help taking advantages of services that already exist, but which most of the times are under exploited because their existence remains unknown; thus to promote their usage, matchmaking algorithms are build. Howev...
Conference Paper
Dynamic collaborative environments enabled with multiple computational devices, software and files have always had difficulty sharing these resources in a practical way. Traditionally, people involved in environments like those are forced to waste time and energy trying to locate a resource they do not even know if it exists inside the organization...
Article
Full-text available
The detection of scars in the cerebral cortex usually involves a manual process performed by radiologists, who have to face multiple troubles. For example, the bad calibration of the equipment used to get images of the cerebral cortex can cause spacial and geometrical distortions in the MRI (Magnetic Resonance Imaging) sequences. Owing to the advan...
Conference Paper
Full-text available
Service Discovery Protocols have been developed for applications to take advantages of services shared over networks. Each protocol provides a way for applications to ask for the type of services they need. In return, applications receive information about services that could fulfill their needs. However, such protocols do not supply enough support...
Conference Paper
We propose an access control method based on the combination of two biometric recognitions: voice and face. In particular, our face recognition algorithm aims at determining a person's identity when he/she is involved in situations in which his/her face is rotated in a shoulder to shoulder trajectory, which is a common behavior on people with a ste...
Conference Paper
Full-text available
Most of the working environments offer multiple hardware and software that could be shared among the members of staff. However, it could be particularly difficult to take advantages of all these resources without a proper software support capable of discovering the ones that fulfill both a user’s requirements and each resource owner’s sharing prefe...
Conference Paper
In this paper, we propose an access control method based on the combination of two biometric recognitions: voice and face. This method can be integrated into several systems, as it has been developed as a Web application, so it is highly multi-platform. In particular, our face recognition algorithm aims at determining a person's identity when he/sh...
Conference Paper
Full-text available
Nowadays, the detection of scars in the cerebral cortex usually involves a manual process performed by neurologists and radiologists. It is a difficult task to carry out, since multiple troubles have to be overcome, from bad calibration of the equipment used to get the cerebral cortex images to several errors, such as spacial and geometrical distor...
Article
Nowadays, organizations include a large number of physical resources (e.g., meeting rooms, classrooms, and auditoriums) and computing ones (e.g., scanners, plotters, and handheld devices) distributed among different offices and buildings. Typically, these resources have to be shared among colleagues, because it is impossible for each collaborator t...
Conference Paper
The majority of the solutions proposed in the domain of service discovery protocols mainly focus on developing single-user applications. Consequently, these applications are unaware of third-party interventions supposing that nobody interferes nor observes. This paper describes a system for discovering sharable resources in ubiquitous collaborative...
Conference Paper
An intelligent area integrates both Internet and Intranet software/hardware supports (from small embedded sensors to powerful and dynamic computing devices) to provide information about each artifact state (e.g., a power failure of the refrigerator) without user intervention. This technological sophistication can be achieved by means of service dis...
Conference Paper
Most research works in ubiquitous computing remain in the domain of mono-user systems, which make assumptions such as: “nobody interferes, observes and hurries up”. In addition, these systems ignore third-part contributions and do not encourage consensus achievement. This paper proposes a system for managing availability of distributed resources in...
