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
1960 1970 1980 1990 2000 2010

• Idea dates back to the 1960s (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
• 1980s general purpose wearable computers
  developed

6
History (continued)
1960 1970 1980 1990 2000 2010

• In 1990s 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

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
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
