Switching on my ears

by Shane Morris, at UX New Zealand.

Designing a hand-held device presents a number of challenges. Designing that device for use by folks with impaired physical abilities introduces another layer of complexity. Ensuring that the experience is appropriate for an audience from five year-old kids to ninety five year-old retirees controlling one of their senses is just downright difficult. Shane recently worked with Australian innovator and international success story Cochlear to design device to help bionic ear implant recipients monitor and control their hearing. The design represented an evolution to a simpler more usable device.

  1. Switching on my ears: Designing a hand held device for

    bionic implant recipients Shane Morris, Automatic Studio Matt Morphett, Amberdew Interaction Design
  2. The cochlear ear implant is the first and only device

    produced by mankind which effectively restores the use of one of the human senses. Professor Gustav Nossal, University of Melbourne
  3. A Lifetime Journey.... Lifetime Needs Service and Repair Service and

    Repair Upgrades Upgrades Troubleshooting Troubleshooting Habilitation Habilitation Programming the implant Programming the implant 6
  4. Scalability Cochlear ™ Nucleus ® 5 System Nucleus CP810 sound

  5. The Business Requirement Existing Requirements • Suit wide range of

    users / hearing configurations • Cater for many more features than there are buttons • Be smaller than a mobile • More useful than a credit card sized remote New Requirements • Demonstrably (testably) Better Than Existing UI • Minimise Change Management • Maintain Backwards Compatibility • Establish Extensible Platform – Start With Scalability Suite ? ? 23
  6. Deliberately Unstructured Research Recipient Appointments With Audiologists Sat in on

    Clinical Trials With CI Recipients • Cochlear Implant Forums & Blogs • Followed Twitter Accounts for the Deaf Community • Downloaded iPhone Rehabilitation Apps • Wore the Cochlear Test Rig Around for a Day • Spoke to the Support-Line Manager • Looked Outside the Industry • Undertook Usability Testing • Taught Preschoolers About Cochlear Implants. 24
  7. Who Are Our Users? Secondary Personas • Parents • Carers

    Primary Personas Elderly Adult Young Person Tertiary Personas • Clinicians Timid Adventurous 25 MM1
  8. What Do Users Need To Do? Adjust their hearing •

    Select a Program • Change Volume • Telecoil Check that everything is OK • Battery levels • Sound coming in • Identify / Troubleshoot Issues Establish their own hearing configuration ... + Dozens of other things 26 MM2

  16. Training Audiologists as Testers How 1. Wrote 1st Protocol &

    Materials 2. Conducted 1st Round Testing 3. Bought Steve Krug’s Book 4. Observed 2nd Round Testing 5. Mentored 6. Left them to rounds 3, 4 and 5 7. Were very responsive to results Benefits • SMEs Become UX Evangelists • Impartial Validation • …yet still tight, respectful relationship 37
  17. Reflection • Much of our experience and techniques from screen-based

    design translated well to devices But device design, and medical device design, is different • Prototype, prototype, prototype – To scale • Enlist client staff as testers • Accept unreasonable constraints, demonstrate value, then loosen constraints over time • Don’t take on a medical device project because you think it will be good for your portfolio 38
