  1. PT Kinection An Augmented Reality Based At-Home PT Facilitator Using Xbox Kinect EDIT 732 – Group 3

  2. Background and Problem • Physical therapy can help patients avoid surgery, reduce chronic pain, prevent permanent damage and recurring injury through rehabilitative exercises and intervention • For best results, most patients are prescribed a home-exercise program in addition to office visits • Noncompliance can negatively impact patient recovery • As many as one third to two thirds of patients are noncompliant with exercises (Sluijs, Kok, and van der Zee, 1993)

  3. Prior Analyses

  4. User Data Target Audience Learner Needs Any time access Visual representation of the exercise Audible instructions Immediate feedback • Physical therapy (PT) patients • Wide range of ages • Variety of reasons for therapy • Congenital • Degenerative • Sports-related, etc. • As diverse as the general population

  5. Learning/Technology Gaps • No confirmation of proper form • No realistic model of behavior • Lack of sufficient communication methods • Lack of motivation

  6. Summary of Findings • Patients and physical therapists need to improve communication • Physical therapist need a way to hold patients accountable • Patients need immediate feedback • Patients are not motivated to complete their exercises • The target audience is relatively technology savvy

  10. Objectives and Solution System Performance Learning Objectives Desired Performance of Solution System Confirm proper form Display realistic model behavior Provide unconventional means of communication with PT Motivate patient Provide immediate visual and audible feedback Be accessible any time • Motivate patients to regularly practice prescribed at-home exercises • Educate patients between regular home exercise program and better recovery outcomes • Empower patients to be confident in their skill at performing the home exercise program • Improve patient accountability for exercises

  11. Proposed Solution System Xbox 360 Kinect • A hybrid device that generates AR using a color (RGB) camera • A depth sensor • A microphone array • A tilt sensor • Skeletal tracking • Gesture Recognition

  12. Benefits to Potential Patients • Simplifies communication with PT • Increases patients’ compliance • Motivates and encourages patients • Provides a realistic example of performance • Provides any-time access to resources

  13. Benefits to Physical Therapist • Monitor patients’ progress • Simplifies communication • Ensures that patients have access to a realistic example of performance • Motivates patients to perform prescribed exercises • Encourages patients to overcome barriers • Ensures patients’ continued visits to PT office

  25. General Design Notes • Exercise screens generally divided into three areas • Mentor area in upper left • “Active” work area • Toolbar/menu at bottom • Elements can be “hidden” to reduce distractions and expanded when needed • Repeated elements (round buttons, rounded edges, etc) lend themselves toward sense of unity • Rounded edges for approachability, but mindful to not appear too juvenile • Blue tones chosen to indicate health or wellness • Colors differentiate PT Kinection from other Xbox system menu colors (green, red) • San Serif font for easier readability

  42. Summary • Briefing Report – Determined that there is a problem, defined barriers and drivers, and proposed an augmented reality-based solution system • Needs Analysis – Performed a thorough investigation of the target audience, determined task order, and further outlined the consideration of AR using Xbox Kinect as a solution for identified learning and technology gaps • Personas – Defined potential patients/users and their PT experience and the affects on health, and PT distribution of home exercise prescriptions, and user affects on health • Prototype – Developed a preliminary prototype, gathered comprehensive feedback from potential users, defined changes, and made corrections resulting in a final prototype that addresses the original learning problem, the defined learning objectives, technology and learning gaps, and potential users’ wants and needs
