  1. Chapter 5by Judith A. Effken Improving the Human Technology Interface

  2. Objectives • Describe human-technology interface. • Explore human-technology interface problems. • Reflect on the future of the human-technology interface.

  3. Key Terms Defined • Cognitive Task Analysis • Cognitive Walkthrough • Cognitive Work Analysis • Ergonomics • Field Study

  4. Key Terms Defined • Gulf of Evaluation • Gulf of Execution • Heuristic Evaluation • Human-Computer Interaction • Human-Computer Interface

  5. Key Terms Defined • Human Factors • Human-Technology Interaction • Human-Technology Interface • Situational awareness • Task analysis

  6. Key Terms Defined • Usability • Workaround

  7. Human Technology Interface • The help of hardware/software • Human-technology interfaces in healthcare • Examples of human-technology interfaces • Human interfaces differ

  8. Human Technology Interface • How information is presented • What telehealth allows • What human-technology interfaces present • The use of large databases

  9. Human Technology Interface Problem • Up to 87% of all patient monitoring incidents are a result of? • When does human error occur?

  10. Improving Human Technology Interface • What we can learn from other fields • The focus of users • What does a good design consist of? • When should formal evaluation take place?

  11. Improving Human Technology Interface • Task Analysis • Cognitive Task Analysis • Cognitive Work Analysis • Five types of analysis

  12. Improving Human Technology Interface • Principles and techniques of developing human-technology interface • Presenting clinical data • A “transparent” interface • How does an interface become “transparent”?

  13. Improving Human Technology Interface • How to have an easy interaction? • Usability • Evaluation of new human-technology interfaces • Typical usability indicators

  14. Future of Human Technology Interface • Improving human-technology interface • Advances in anesthesia machines • Anesthesiologists working to improve computer interface

  15. Future of Human Technology Interface • What was the cause for a drop in anesthesia related deaths? • Is informatics there yet?

  16. Thought Provoking Questions You are a member of a team that has been asked to evaluate a prototype PDA-based application for calculating drug dosages. Based on what you know about usability testing, what kind of test (or tests) might you do and why?

  17. Thought Provoking Questions Is there a human-technology interface that you have encountered and you think needs improving? If you were to design a replacement, what of the analysis techniques you read about would you choose? Why?
