Digital applications for clinical cognitive assessement
Digital applications for clinical cognitive assessement
I designed Virtual Reality applications for providing ecological/realistic assessement of cognitive impairments and declines as nearly experienced in real-life settings.
To promote cognitive training at home, I alo worked on online interactive cognitive assessement to catch training outcomes on cognitive and everyday functionnings..
Virtual Bordeaux hospital district
This app successfully assesses spatial orientation and Virtual-Real transfer of spatial learning for a large range of populations (young, older adults, early stage of Alzheimer disease, see publications).
Virtual Apartment
The virtual HOMES test (Human Object Memories from Everyday Scences) provides a clinical Memory assessment as in California Verbal Learning test (learning interference, clustering, false recognition, Free recall and recognition, etc.) while exhibiting a closed relationships with everyday memory complaints in Young, older adults and in Traumatic Brain-injury patients (see publications).
Attention & Memory assessment
(Online) Cognitive test Battery (in collaboration with Onepoint), comprising 6 standardized cognitive tests (MOT serious games: multi-object tracking, enumeration; go/no-go, Corsi (straight; reverse), load-induced blindness, attentional switching task, “memorability” test). Easily deployed as a web application, it can be reused and modified for new experiments. The tool is documented to facilitate deployment and results analysis : https://github.com/flowersteam/cognitive-testbattery
Rather than opting for a commercial solution, we have developed a proprietary platform that gives us total control over its operation, notably for the automation of data cleansing and pre-processing prior to statistical analysis. This tool enables us to be autonomous for all online experiments.
Curiosity-driven Educational technologies
Curiosity-driven Educational technologies
As a result of the CuriousTech associated team, several ET are designed for fostering leaning by curioisity
KidAsks (in collaboration with EvidenceB) is a TE that trains children in divergent thinking through questioning and the invesigation of knowledge on informative texts, with the aim of fostering learning based on epistemic curiosity (Thesis by Rania Abelghani). More information http://curious-kids.herokuapp.com/
KidsReflect (2022) (in collaboration with EvidenceB), a TE in the form of a metacognitive workshop for children aged 9 to 11; it includes, on the one hand, video resources and Quizzes on the 4 metacognitive components linked to curiosity-based learning (identifying uncertainties; generating hypotheses; Investigating by asking questions ; evaluate the value of the information found), and on the other an interactive web application for progressive practice of these 4 metacognitive skills on reading-comprehension tasks with pedagogical support from conversational agents (instructions for carrying out the task, hints and suggested answers) (Thesis R. Abelghani).
Self-determination-driven AT devices for cognitive impairments
Self-determination-driven AT devices for cognitive impairments
Because cognitive impairments are often invisible, they are the poor relation of AT research, and my work seeks to remedy this to promote a greater inclusive society.
HomeAssist platform targeting assistance and monitoring of daily activities for aging in place of the elderly or access to independent living for people with intellectual disabilities. Its originality is to be designed according to self-determination principles. In 2019, this platform led to the creation of the UT4 start-up (Founders: J. Durand & PY Chaussé) with support from INRIA's transfer services, BPI and the Bordeaux UNITEC incubator - 2 associated software licenses.
Aïana. From the principles describe in the MOOC Accessibility for People with disabilities (PWD) project and through co-design sessions with PWD and experts, we developed Aïana, an accessible MOOC player. Aïana has been used in the context of a MOOC on Digital Accessibility available on the national platform FUN (with more than 5600 registered users from 60 different country nowadays). Moreover we observed how learners were using Aïana through activities follow-up and questionnaires that we proposed to them. These measures enabled us to validate two main results : first, in contradiction to “classic” MOOC, percentage of PWD following our MOOC was equivalent to the global population, which is a strong indication of its accessibility. Second, we observed a learning performance at the end of the MOOC equivalent for PWD and other learners while being associated to high self-determination feelings in users. Thus, it has been particularly beneficial for learners with cognitive impairment.
School+/College+ is a digital classroom assistant designed according to self-determination principles. It facilitates the inclusion of pupils with autism spectrum disorders (ASD) in regular classes. The first version of this tool, tested in three secondary schools on 50 students from the Bordeaux regional education authority, showed that it brought real benefits to children with ASD. This application received the academic award for educational innovation in 2014. More information.
ToGather/ TousEnsemble is a digital coeducation assistant. Using participatory methods, it was co-designed with parents, teachers, and medical-social professionals to provide them with interactive services with continuously updated content, including the student’s strengths and weaknesses, a longitudinal tracking of acquired skills, a shared notebook of psychoeducational solutions, shared messaging, and a meeting manager. After conducting an ergonomic evaluation of the proposed interface, the tool was developed and tested under real conditions with about a hundred participants. This field study aims to assess the impacts of using this tool on parent-professional and interprofessional relationships, their communication, and their collaboration practices. More information
Cognitive training for older adults
Cognitive training for older adults
To individualize training difficulty, the ZPDES algorithm designed by Flowers team is implemented for maximizing learning progress to reinforce the learner's intrinsic motivation
Adaptive MOT training is a Intelligent Tutorial System applied to attentional training based on the Multiple Objects Tracking task, which embeds an algorithm (ZPDES) for customizing the learning path according to the hyperparameter (number of targets) and 4 other parameters (speed, target spacing, number of distractors, presentation time) (PhD of Maxime Adolphe).
