Detect (3-Axis) Measure Transfer (Wireless) Low Energy Consumption Precision! Software Compatibility Performance No Magnetic/Visual Interference Accommodate Range of Patients Firmly Attachable Compatible Interface Has Mechanical Zero Lightweight/Portable Reliable/Robust Physical 9

 Current Task: establish direction Find multiple solutions for a single problem  Work with team I to develop SENSOR only  Work in team II with 2 subdivisions Integrate sensors into past project  Project Goals: Regarding most urgent Nazareth needs Consider applicability in multiple fields 10

 Scope! General project objectives  How does software fit in?  Weight regarding:  Focus of project  Software vs Hardware  Team Members  Need to confer with SE/EE Departments 11

Make product accessible for people with various conditions do not impede patient's natural movement built to fit all sizes of people easy procedures Patient Use repairs possible by person without technical expertise easy procedures provide helpful feedback to PT (not a jumble of numbers) Therapist Use 13

 Motion tracking sensor/other electronics attachment methods  Integration of improved attachment methods into an improved Motion tracking system 14

 Primary Concerns No feedback control for winch  Create a system to prevent future winch failures Pedal resistance  Jumpy  Not enough resistance  Patients refuse to use bike  Design a more reliable pedal resistance system Handlebars  Awkward, uncomfortable position  Reposition handlebars to be comfortable for all patients 16

 Secondary Concerns Handlebars  Design handlebars to move and mimic a normal bike Display  Obscured for some patients  Not big enough  Redesign the display for all patients to be able to view  Tertiary Concerns Display  Redesign display to give a more valuable feedback to patient and physical therapist  Audio feedback to patient and physical therapist Pedal  Easily adjustable pedal resistance 17

Background ResearchProject PlanningConcept Development 19

 Common Themes Ease of use Accuracy and reliability Incomplete aspects 20

 Overview Provide a review of past MSD project at the clinic Identify common themes of success and failure Develop a theory of design for clinic projects 21

 Goals Improve the design process and design experience Improve the outcomes of projects for the clinic 22

 Market Considerations Not a marketable product Will benefit clinic and MSD program 23

 Compile customer needs (In progress) Previous projects A lot of information  Hard to organize and analyze 24

 Conduct Stakeholder Interviews (planning) Identify new or general themes  Stakeholders Clinic Patients MSD Program  MSD Leadership  MSD Teams  Faculty Guides 25

 Organize, Analyze and Prioritize Determine best approach  Affinity Diagrams  One for each stakeholder  Use house of quality to determine relative importance of needs  Affordance based design? 26

 Stakeholders  Faculty Industrial and Systems Engineering Industrial Design  Publications ASME – Design Theory and Methodology Conference Text 27
