En 2002
Charles Gouin-Vallerand est professeur agrégé en technologie de l’information au Département de systèmes d’information et méthodes quantitatives de gestion de l’Université de Sherbrooke. Par le passé, il était professeur agrégé en informatique à la Télé-Université du Québec (TÉLUQ) à Montréal (2012-2019) et, auparavent, boursier postdoctoral au Human Computer Interaction Institute de l’Université Carnegie Mellon (2011-2012).
Les expertises du professeur Gouin-Vallerand sont dans l’interaction homme-machine (réalité augmentée, informatique mobile, gérontechnologies), l’informatique omniprésente et les systèmes contextuels. Il est particulièrement intéressé par l’utilisation des informations contextuelles dans des environnements intelligents tels que les maisons intelligentes, les villes intelligentes et les espaces intelligents ouverts, pour fournir de nouvelles façons d’aider les utilisateurs et de reconnaître les activités humaines.
Il s’intéresse également aux technologies de réalité mixte et augmentée pour soutenir les tâches ou les activités quotidiennes dans les scénarios industriels et de santé (par exemple, les personnes atteintes de troubles neurocognitifs).
Les villes et maisons intelligentes, avec leurs capteurs et leurs appareils sont de bons environnements technologiques dans lesquels il est possible de déployer des systèmes sensible au contexte et où de grandes quantités d’informations peuvent être collectées afin de supporter la reconnaissance de l’activités et la livraison de services d’assistance. Le premier axe du programme de recherche de Prof. Gouin-Vallerand est donc de concevoir des stratégies et des algorithmes pour analyser l’information contextuelle et en extraire des modèles ou des informations telles que les activités en cours ou les habitudes.
Ces stratégies et algorithmes doivent gérer plusieurs contraintes : l’hétérogénéité des données, les limites du matériel ou l’analyse en temps quasi réel des données. Dans ses travaux récents, Prof. Gouin-Vallerand a développé des algorithmes de reconnaissance de l’activité pour des utilisateurs mobiles en milieu urbain basés sur des systèmes hybrides. Ses activités de recherche intègrent donc la poursuite de ces travaux sur la reconnaissance de l’activité humaine en milieu urbain, en élargissant la gamme des activités reconnues (activités simples ou complexes), en reconnaissant les activités multiutilisateurs et en élargissant l’utilisation de la logique temporelle.
Le deuxième axe de son programme de recherche inclut des travaux de recherche interdisciplinaires en informatique diffuse et en interactions humain-machine et se subdivise en deux sous-objectifs : (a) la conception et l’évaluation d’orthèses cognitives logicielles en réalité augmentée qui prennent en compte l’activité courante et le contexte des utilisateurs pour mieux assister les utilisateurs dans leurs tâches et activités; (b) la conception et l’évaluation de techniques d’interaction multimodale en réalité augmentée afin de permettre aux utilisateurs de mieux interagir avec les orthèses cognitives proposées et de tenir compte des limitations des utilisateurs (e.g. physique ou lié à la tâche). Apporter de l’assistance cognitive et à la tâche en réalité augmentée comporte plusieurs défis du point de vue facteur humain et technologique, tels que l’orientation et l’interaction 3D, les interactions multimodales, la charge mentale, etc.

abstract = {Background: Mixed reality is an emerging technology allowing to "blend" virtual objects in the actual user's environment. A way to realize this is by using head-mounted displays. Many recent studies have suggested the possibility of using this technology to support the cognition of people with neurodegenerative disorders. However, most studies explored improvements in cognition rather than in independence and safety during the accomplishment of daily living activities. It is therefore crucial to document the possibility of using mixed reality to support the independence of older adults in their daily life.
Objective: This study is part of a larger user-centered design study of a cognitive orthosis using pure mixed reality to support independence of people living with neurodegenerative disorders (NDs). The objectives were to explore: (1) What are the main difficulties encountered by older adults with NDs in their daily life to ensure that the pure mixed reality meets their needs; (2) What are the most effective interventions with this population in order to determine what types of assistance should be given by the pure mixed reality technology; (3) How should the pure mixed reality technology provide assistance to promote safety and independence at home; and (4) What are the main facilitators and barriers for the use of this technology. Methods: We conducted a descriptive qualitative study with 5 focus groups with experts of the disease and its functional impacts (n = 29) to gather information. Qualitative data from the focus groups was analyzed through an inductive thematic analysis.
Results: The themes emerging from the analysis will provide clear guidelines to the development team prototyping a first version of a cognitive orthosis based on pure mixed reality.
Conclusions: The cognitive orthosis that will be developed in the light of this study will act as a proof of concept of the possibility of supporting people with neurodegenerative disorders using pure mixed reality.},

abstract = {The current Internet of Things (IoT) development involves ambient intelligence which ensures that IoT applications provide services that are sensitive, adaptive, autonomous, and personalized to the users' needs. A key issue of this adaptivity is context modelling and reasoning. Multiple proposals in the literature have tackled this problem according to various techniques and perspectives. This chapter provides a review of context modelling approaches, with a focus on services offered in Ambient Assisted Living (AAL) systems for persons in need of care. We present the characteristics of contextual information, services offered by AAL systems, as well as context and reasoning models that have been used to implement them. A discussion highlights the trends emerging from the scientific literature to select the most appropriate model to implement AAL systems according to the collected data and the services provided.},

The keycube comprises 80 keys equally disposed on 5 faces. In this paper we investigate keycube text entry performances and the potential typing skill transfer from traditional keyboard. Using prototype implementations, we conducted a user study comparing different cubic layouts and included a baseline from traditional keyboards. Experiments show that users are able to attain about 19 words per minute within one hundred minutes of practice with a QWERTY-based cubic layout, more than twice the speed of an unknown-based cubic layout with similar error rate, and about 30% of their speed with a traditional keyboard.},
