Biography

Research program

The ubiquitous computing in our societies invades large areas of human activity, including the search for information, the organization of daily life, entertainment and communication with friends. But elderly people and people with cognitive disorders due to illness or trauma do not benefit as much as they can from the use of new technologies to make it easier to stay at home and stay in touch with their loved ones.

The purpose of my research is to identify the guidelines that applications must meet in order to be accepted and used by people with specific needs. In previous research, I designed assistance technologies using participatory design and a multidisciplinary approach. These technologies include technologies that facilitate the organization of schedules and technologies accompanying complex activities, whether on mobile devices or integrated into a smart apartment.

Research questions are at various levels of design

• how is the acceptability of assistive technologies built and evaluated throughout the participatory design?
• how is the interaction with assistive technologies anchored in a familiar environment with modalities providing pleasure and emotion?
• how to introduce assistive technologies so that people with cognitive impairments easily take ownership of it?
• how do technologies offer assistance to people with cognitive impairments and facilitate support from those around them?

The analysis frameworks of my research are thus user-centered design, participative design, instrumental approach, diffuse computing and tangible interfaces. My current research focuses on the design of pleasant and emotional interaction through a virtual agent, multi-layer interfaces to facilitate learning and integration of assistive technologies in intelligent habitat to make more effective reminders of activities.

Publications

My research focuses on cognitive assistance in intelligent housing to support home support. I rely on the domains of human machine interfaces and diffuse computing. My research is interdisciplinary and emphasizes participatory design to ensure a meaningful and enjoyable cognitive assistance for people and their caregivers.

This article presents a co-design research in which people with head trauma and their caregivers participated in design groups of an application offering calendar and budget management. An evaluation at home showed the benefits of this application.

DOI: 10.1080/09602011.2016.1172491

This article presents a research on the effects of a timetable application specifically designed for people with Alzheimer's. It follows a research in co-design with computer scientists and a neuropsychologist and shows the need to associate an appropriate method of learning to people with Alzheimer's to integrate in their daily life this alternative to the maintenance at home.

This article presents the methodology for the integration of a useful, emotional virtual agent in the Amelis interactive calendar conceived in co-conception with 35 elderly Quebecers and French people. The emotional model is based on the Big Five theory of personality and is inspired by the SIMPLEX model.

This article discusses how multilayer interfaces make learning a calendar easier for someone with neurodegenerative disease. By adding features as the previous features are acquired, the person selects the information better and lives more success.
