Project Task  Improve the life of our client  Provide higher autonomy  Combine two wheelchairs 4

Project Progress Usability testing Construction Design Requirements analysis 5

Background: Client  Nahuel ; 13 years old  Dystonic, SpasticTetra Paresis  In buggy wheelchair, strapped  Muscle excercises with physiotherapist 6

Introduction movie client 7

Background: Clients Abilities Cognitive Physical No control Learning by body & facial time movements Acknowledge No speech differences Reacts to Little/No emotions strength 8

Buggy Wheelchair ‘ EASys ’ from Thomashilfen  Seating construction is used  Ergonomic benefit 9

Electric Wheelchair ‘ Power Picco ’ from Meyra  Bottom part is used  Stability benefit 10

Requirements Company • Realistic Product; Meets standards • Indoor usage Client • Fits user’s capabilities • Contributes to social and physiological al benefits Supervisor • Documentation • Effective teamwork • Low budget 11

Project Overview Universal Seating Adjustment Handles Steering System 12

Why a new Seat Fixture System? Problem • Combine chassis of electric wheelchair and seat • Keep each advantages How to solve it? • Designing different solutions for fixing the seat • Evaluating the convenience 13

Design: Universal Seat Fixture Universal Stable Secure 14

Project Overview Universal Seating Adjustment Handles Steering System 15

Why adjust the Handles? Problem • The seat covers the fixing place • Handles are too short for the pusher How to solve it? • Designing a new solution • Enlargement and addition of a steel block to move the fixing place 16

Design: Handles 17

Project Overview Universal Seating Adjustment Handles Steering System 18

Why a new Steering System? Problem • Actual solution not accessible • Not enough grip in hands How to solve it? • Research on steering systems • Comparing steering approaches • Evaluation of convenience for the client 19

Which Steering Systems are on the market? Joystick Chin Sip-n-Puff Head Voice Tongue Eye Gaze Brain 20

Which System meets the requirements of the client? 21

Which Steering System is the most convenient? Steering Systems 10 Chin 8 6 4 Head 2 Brain 0 -2 Sip-n-Puff Eye-Gaze -4 Joystick Voice -6 Tongue 22

Why Chin Control? - + Less space for head Safe system movements Less Short Not integrated in communication technical develop- system barriers ment time Intuitive steering 23

Design: Steering System Accessible Adjustable Economical Convenient 24

From Joystick to Chin Control 25

Final product 26

Usability & user interaction 27

Usability for the client - + Quick Still needs understanding help to steer Easy to learn Improve his new Easy capabilities interaction with the others 28

Wheelchair carriage - + Steering System can Does not be fold unmounted Easy Heavy transport of the buggy 29

Costs Estimated Project Costs 300 € 250 € 200 € Costs in € 150 € 100 € 50 € 0 € Pushing Steering Seating system Total handles System Materials 13 € 6 € 28 € 47 € Human labour 35 € 65 € 120 € 220 € 30

Conclusion Develop a psychological Challenging benefit Project Opportunity to have autonomy Nahuel will feel happier about the interaction with others 31

Future work Last adjustments Implementation of the steering of a safety system system 32
