Transcript

  • 1. Kari Rice Human Factors Engineer
  • 2. Experience • Nine years experience in user research, user interface design, and usability • Experience with: – All phases of Product Development – Variety of development processes – Mobile Devices, PC Applications, Handheld Devices – User Research, Product Definition, Use Interaction Design, Human Factors Analysis, User Guides – Medical, Consumer
  • 3. Zeno Collaborated with local design firm on next generation of acne treatment device. Worked closely with industrial designer to create physical prototype with functioning user interface. Planned, created, and conducted customer interviews and usability testing. Provided feedback and recommendations for hardware and software design to improve the ease of use of the device.
  • 4. NeuroVista Consulted for a local company developing an implantable epilepsy device. Conducted heuristic evaluation of wearable device including hardware and software. Planned, created, and conducted usability evaluation of device and provided recommendations for improving usability and ergonomics of device.
  • 5. Stent Graft Consulted with local design group to redesign an aortic stent graft in a compressed schedule. Added new features but improved ease of use by considering the user, workflow, and ergonomic guidelines.
  • 6. Northstar Programmer The programmer used for Northstar’s clinical trials was confusing and error-ridden. Each user needed a significant amount of training to successfully operate the programmer and the number of complaints reported to Northstar was unacceptable. I redesigned the programmer using a user centered process and significantly improved the user experience, decreased complaints to the company, and eliminated the need for individual training.

  • 10. Tegic Communications Planned, created, and executed extensive benchmark test. Results were used by marketing, sales, and development. Created specification for ideal T9 implementation to be used as a guideline for future development efforts.
  • 11. SonoSiteiLook The iLook was a completely new concept for SonoSite. Previous products were hand carried but iLook was designed to be handheld. Additionally, iLook was designed for non-traditional users with little to no ultrasound experience. I conducted extensive user research to identify user needs and requirements. These needs and requirements were used to drive the design. A thorough ergonomic evaluation was completed and extensive usability testing was conducted to optimize comfort during use. I worked closely with industrial design and mechanical engineering to create a form factor that was comfortable for all users.
  • 12. Evolution of iLook Form Factor
  • 13. SonoSiteiLook User Interface While working on the form factor, I was also developing the user interface. I conduced several tests to determined the input method, created the screen layout, determined the interaction model, and created low-fidelity prototypes. Early integration of the hardware and software was prototyped by using a wood model with a flip-chart user interface. This was evaluated during usability testing.
  • 14. iLook Final Design
  • 15. FiatLux Imaging Conducted user research to establish user requirements for next generation product. Created design standard to ensure consistency across designs. Conducted heuristic evaluation of existing software to identify strengths and weaknesses.
