3
Backgrounds and Purpose

• Example of conventional control room with digital
  technologies

4
Background and Purpose

• Example of fully computerized control room with
  minimal analog backup controls

5
Backgrounds and Purpose

• Characteristics of Annunciator-based Tiled Alarms
• Presents Alarms in a Spatially Dedicated Position
• Continuously Visible and Accessible in Parallel
• Allows the Plant Operating Personnel a Rapid
  Detection and Pattern Recognition

6
Backgrounds and Purpose

• Purpose
• To set up some requirements that the tiled-alarm
  display format should have
• To present a new tiled-alarm display method that
  meets those requirements

7
New Tiled Alarm Display Method

• Various Formats of Alarm Display Integration
  Display

8
New Tiled Alarm Display Method

• Various Formats of Alarm Display Message List

9
New Tiled Alarm Display Method

• Various Formats of Alarm Display Hierarchically
  Overlapped Tiled-Alarm Display (HOTD)

10
New Tiled Alarm Display Method

• Requirements of a New Tiled alarm Display Method
• The display method should be assured that the
  only one display page accommodate all the tiled
  alarm information.
• The navigating task of the method  should be done
  with little attention, so operators can
  concentrate the primary task
• The method  should contain a maximum of 50 alarms
  each page.

11
New Tiled Alarm Display Method

• Concept of Elastic Tiled-Alarm Display (ETD)

12
Evaluation for Engineering Judgment

• Cognitive-Perceptual-Motor GOMS (CPM-GOMS)
• one of the four popular variants of GOMS family
  1
• widely recognized as a usability evaluation
  method in HCI
• predicts execution time based on an analysis of
  component activities

13
Evaluation for Engineering Judgment

• Example of CPM-GOMS analysis

14
Conclusion

• Execution Time ETD Vs HOTD
• single alarm acknowledgement task
• Execution Time with ETD 1750msec
• Execution Time with HOTD 1950msec

15
Further Works

• Need Experimental Validation
• Hypothesis
• Elastic Tile Display yields faster performance
  than Hierarchically Overlapped Tiled-Alarm
  Display for alarm acknowledgement  task.
• Elastic Tile Display yields faster performance
  than Hierarchically Overlapped Tiled-Alarm
  Display for situation awareness task.
