Ubiquitous inference of mobility state of human custodian in people-centric context sensing
People-centric sensing using people's smartphones offers new research opportunities for large case studies. It presents many challenges, e.g., efficient capture of person's mobility, understanding of context changes and preservation of user privacy. We propose an accurate and energy-efficient method able to capture user's mobility, thus the context changes, while...

Deriving Connectivity and Application Usage Patterns From Longitudinal Mobile Phone Usage Data
In this paper, based on the Mobile Data Challenge data obtained from the Lausanne data collection campaign, our research aims first to derive network connectivity (e.g., WLAN, 3G) and its Quality of Service (QoS) and mobility patterns of the mobile users, as this connectivity and QoS relate to the user's application activity. Second, we aim to understand how these patterns...

Estimating People Perception of Intimacy in Daily Life from Context Data Collected with Their Mobile Phone
Nowadays, personal context is extensively used in personalized mobile services. However, gathering this kind of information may compromise the privacy of the user. Moreover, the number of services that collect and share the personal context with others is growing. Yet, the users are not able to easily control what information is shared and with whom. An important step towards this...

Phone in the Pocket: Pervasive Self-Tracking of Physical Activity Levels
Mobile (smart)phones prevail in our daily life activities, and in our research we aim for it to provide pervasive services for wellness. Therefore, we assess the phone's feasibility to unobtrusively, continuously and in real-time track its user's physical activity and the resulting energy expenditure (EE). Activity Level Estimator (ALE) is an Android OS application...

Video games as a complementary therapy tool in mental disorders: PlayMancer, a European multicentre study
Background: Previous review studies have suggested that computer games can serve as an alternative or additional form of treatment in several areas (schizophrenia, asthma or motor rehabilitation). Although several naturalistic studies have been conducted showing the usefulness of serious video games in the treatment of some abnormal behaviours, there is a lack of serious games...

Factors influencing quality of experience of commonly used mobile applications
Increasingly, we use mobile applications and services in our daily life activities, to support our needs for information, communication or leisure. However, user acceptance of a mobile application depends on at least two conditions; the application's perceived experience and the appropriateness of the application to the user's context and needs. Yet, we have a weak...

Abstract information visualization in interactive 3D virtual environments: conceptualization and usability evaluation
Abstract information refers to information that a user can't directly obtain just by visualizing the spatial information of objects in a 3D virtual environment (3DVE). This thesis first reviews the state of the art on interactive 3DVEs development, abstract information visualization techniques and the evaluation of interactive 3DVEs. Then, this thesis presents a conceptual model...

Opérations sur des ressources hétérogènes dans un entrepôt de données à base d’ontologie
Le nombre croissant d’ontologies disponibles sur le web a justifié l’apparition d’entrepôts d’ontologies. Cependant, peu d’entre eux intègrent également des ressources hétérogènes de type ontologique, textuelle, linguistique et terminologique. De plus, ils ne fournissent pas un ensemble complet d’opérateurs permettant la gestion et le traitement de ces ressources. Dans nos...

The Emotional Economy for the Augmented Human : 2nd Augmented Human International Conference
Happiness research findings are increasingly being taken into account in standard economics. However, most findings are based on a posteriori surveys trying to infer how happy people have been. In this paper, we argue that the advances in wearable computing, especially brain-computer interfaces, can lead to realtime measurements of happiness. We then propose a new kind of economy...

Using digital Phase-Locked Loop (PLL) technique for assessment of periodic body movement patterns on a mobile phone
This paper applies digital PLL (Phase-locked loop) approach to the body movement classification problem. PLLs have been used efficiently in telecommunication to retrieve modulated signals from the background noise. Acceleration sensor signal processing often require the same kind of noise tolerance and the relevant movement patterns are frequently periodic, e.g. walking. The paper...

Mobile User Experience Beyond the Laboratory: Towards a Methodology for QoE-QoS Evaluation in Natural User Environments (A Position Paper)
Inevitably, mobile applications and services on a growing scale assist us in our daily life situations, fulfilling our needs for leisure, entertainment, communication or information. However, user acceptance of a mobile application depends on the application's perceived quality of experience (QoE) and it also includes the criticality of the application to the user's context...

Testing the Usability of Information Visualization Techniques in Interactive 3D Virtual Environments: a Toolkit
Augmenting 3D virtual environments (3DVEs) with additional abstract information, with different data types (such as numbers, texts, images and videos) amplifies and enhances the user's spatial cognition and understanding of geometrical objects in order to perform specific tasks which require both abstract information and a 3D scene. Many interactive information visualization...
