Assistance à la conduite d’un fauteuil roulant : résultats de tests et travaux futurs Innovation, Robotique et Santé : Assistance à la conduite de fauteuil roulant, Rennes, 9 décembre 2016

Device for semi-autonomous assisted navigation • Invacare wheelchair • Dynamic Controls electronics system • 9 US sensors • 4 IR sensors • visual feedback on PC  mainly used for debugging Objectives • the user sets the main direction • the wheelchair deviates around an obstacle  corridor travelling is eased  passing through a doorway is eased Methodology “potential field” (the wheelchair is “pushed away” by obstacles) 2 Rennes, 9 décembre 2016

Methodology of tests PWC activity  focus on developing a methodology of testing AT Participants: 12 disabled persons in 4 countries Canterbury – UK (March 2015) Vlissingen – The Netherlands (April 2015) Lomme – France (May 2015) Gits – Belgium (May 2015) 3 Rennes, 9 décembre 2016

PWC Activity - Participants • 12 powered chair users – 6 male and 6 female; 2English, 2 Dutch, 4 French, 4 Belgians – Ages: ranging between 17 and 64 – Diagnosis: 3 MS, 2 Brain Injury, 2Duchenne MD, Cerebral Palsy, Left side paralysis following stroke, Tetraplegia – Number of years using a PWC: 1 to 16 – Have they received training to drive the powered chair? • YES: 1 UK/ 0 NL/ 3 FR/ 1 B 4 Rennes, 9 décembre 2016

PWC Activity - Methodology • Step 1 – 2 pre-session questionnaires • Technical questionnaire exploring the user experience of PWC use and their expectations for a driving assistance system • Ethics questionnaire exploring the user view point on – How the use of PWC in a daily life enhances and is compatible with good care – What are their feelings by being ask to participate to the tests 5 Rennes, 9 décembre 2016

PWC Activity - Methodology • Step 2 – The driving session on a simulated indoor test course • Drive with [A] and without [B] Driving Assistance - ABABABAB • Data from Observers • Data from the PWC 6 Rennes, 9 décembre 2016

PWC Activity - Methodology • Step 3 – Semi-structured interview using Post- session technical and ethics questionnaires to provide participant feedback on their experience and to collect ideas on how the driving assistance system and the evaluation process might be improved 7 Rennes, 9 décembre 2016

PWC Activity - Methodology • Step 4 – NASA Task Load Index Questionnaire used after the tests to compare the mental and physical activities, time pressure, performance, effort and frustration between driving the PWC with and without the driving assistance device. 8 Rennes, 9 décembre 2016

User feedback of chair development • A rear-view camera for reversing • Autonomous chair for transfers to and from a bed or chair • Use of the Driving Assistance system as a training aid for experienced users in new environments • Feedback to the user – requires a range of options is necessary to suit each user, a combination is also useful so that the user can focus on driving and then look at a display for more information if so required – the type of feedback has to be adapted to the user’s needs • Detection of kerbs and potholes 10 Rennes, 9 décembre 2016

Ethics questionnaire results • Good care : organised around respect, autonomy, empowerment and communication • Autonomy Communication Item Score Score Item Score Score Before tests After test Before tests After test (/9) (/10) (/10) (/10) Having choice 7 6 Time Giving 7 6 Independance 6 6 Explaining information 7 6 Making decision 4 5 Understanding 4 8 information Being able to make 3 5 Verbal communication 5 1 decision Giving choice 3 2 Non-verbal 5 3 communication Other stakeholders (28 participants) • Having choice • Being able to make decision • Independance 11 Rennes, 9 décembre 2016

PWC Activity - Conclusion • Necessity to use semi-structured interviews  allows to obtain rich feedback from the participants • Necessity to train the interviewer • Ensure that the participants have enough time to finish all the assessments in a relaxed way • Fill-in the pre-session questionnaires the day before the tests • This methodology as well as the questionnaires can now be adapted for the development and assessment of any assistive technology . 12 Rennes, 9 décembre 2016

Future project: EDUCAT Empowerment of Disabled people through the User Coproduction of Assistive Technology (2016-2020)
