  1. Wearable Computing Gail Greene Lessner, RN

  2. Objectives • Describe Wearable Computing • List hardware used • Describe one type of hardware used • List software used • Describe one type of software used • Evaluate Usability of Software • Describe Information System used with trend

  3. Objectives (continued) • Evaluate review of information system described • Describe Advantages and Disadvantages • List any legal/ethical issues • Describe necessary Informatic Competencies • List functions and responsibilities of Informatics Nurse • Summarize wearable computing

  4. Wearable Computing • Computer devices that can be attached at the point-of-care • Allow users to work with programs on the go • No delay in inputting or retrieving information

  5. History of Wearable Computing • Idea dates back to the 1960’s (Groen,2010) • Early models not feasible because of large, bulky size • 1966 Ivan Sutherland created first head mounted computer • 1977- Vest and Headset developed to aid the blind • 1980’s general purpose wearable computers developed 1960 1970 1980 1990 2000 2010

  6. History (continued) 1960 1970 1980 1990 2000 2010 • In 1990’s wearable computing swiftly progressing • Carnegie Melon University, Massachusetts Institute of Technology, and Georgia Tech sponsored international symposium on “Wearable Computing” in 1997 • Today, computer fibers being woven in clothing fibers

  7. Wearable Computing Hardware • Motherboard worn in clothes connects all the components • Components placed in different parts of body as needed • Display and Microphone either on wrist or headset • WiFi, Global Positioning System, and Bluetooth Modules • User input can be voice driven or sensed from body motion

  8. Wrist Display • 3.5 inch screen display • Weight 10 ounces • 320 X 240 color display • Touch screen • Backlit Keyboard • Velcro wrist strap

  9. Wearable Computing Software • Augmented Reality Application • Speech Recognition Software • Handwriting and Keyboard Software • Gesture Input Applications • Two Networks required

  10. Speech Recognition Software • Spoken words are made up of 44 possible sounds called phonemes. • Once spoken, the computer splits the overall word sound into its component phonemes • It then identifies what letter sounds each phoneme represents. • Statistical pattern recognition techniques are also incorporated into the software. • The software contains grammatical structure of language to identify which sorts of sentences make sense. • Contain built in dictionaries

  11. Axiom 2 Axiom 3 Axiom 1 Usability of software evaluation • Software is user centered. • Some allowance for evaluation and corrections, but limited • Heuristic evaluations as well as cognitive walkthrough used to develop and evaluate speech recognition software before it is marketed

  12. Meditech(Medical Information Technology) • Captures stores and displays data • Includes patient care documentation • Utilizes customized status boards • Multidisciplinary

  13. Review of Meditech components • Clinical Information System • For use by any Healthcare Clinician • Functions include documentation and processing • Used in a variety of configurations • HL-7 Clinical Document Architecture (CDA) • Utilizes Nursing Minimum Data Sets (NMDS) (Meditech,2010)

  14. Advantages • User friendly, easy to learn • Computer moves with you • Patients data easily obtained • Eliminates unnecessary charting • New technology appeals to net generation

  15. Disadvantages • Small display • Smaller keyboard • Different ways to enter data • Need to enter data while interacting • New technology intimidating

  16. Ethical/Legal Issues • Information can be seen by anyone • Need for careful monitoring • Potential for HIPAA Violations (Groen,2005)

  17. Informatic Competencies • Healthcare provider must be fitted for unit • Provider must be trained on software use • User must maintain an annual competency

  18. Functions and Responsibilities • Informatics nurse specialist must monitor data • INS will provide frequent in-services • INS will help to train staff members • INS will monitor quality assurance

  19. Summary • Wearable Computing fast emerging technology • Patient care and charting become one • Less time spent sitting at desk charting • Better ways to monitor patients
