    PAS TECHNOLOGY CONFERENCE

    Presented by:

    A HIGH PERFORMANCE HMI

    #ptc2013 | 1

    Hector R. Perez HMI Product Manager

  • Technology Conference 2013

    AGENDA HMIs Past and Present

    Common but Poor HMI Practices

    Justification for HMI Improvement

    High Performance HMI Principles and Examples

    Proper and Improper Use of Color

    Depicting Information Rather Than Raw Data

    The Power of Analog

    Trend Deficiencies and Improvements

    Depicting Alarm Conditions

    Display Hierarchy and the Big Picture

    The High Performance HMI Development Work Process

    Obstacles and Resistance to Improvement

    Cost-effective Ways to Make a Major Difference

    #ptc2013 | 2

  • Technology Conference 2013

    THE HMI OF THE PAST

    Numbers sprinkled on a screen Improper use of color No trends No condition information

  • Technology Conference 2013

    Poor HMIs can Kill ! Early, numeric-entry-and-display-based Flight Management Systems were complex to program

    FMS input error: American Airlines Flight 965 collides with a mountain in South America.

    Korean Airlines flights KAL 902 (in 1978) and KAL 007 (in 1983) were both shot down by the Soviets due to navigation input errors.

    Lack of situation awareness is common in fatal aircraft accident reports.

    Speed Altitude Position Course

    Time Enroute Time to next

    Waypoint Time to

    Destination

    Fuel Remaining Proximity to Ground Proximity to Rising

    Terrain Nearby Airports

    Positions of nearby aircraft

    Real-time weather & lightning

    Glide Radius

    Engine diagnostics Data on Available

    Services at Airports

    ALARMS AND SITUATION AWARENESS

    #ptc2013 | 10

    Alarm Management

    Alarm system is reliable

    Operators have a high degree of

    confidence in the alarm system

  • Technology Conference 2013

    YOUR ALARMS ARE NOW UNDER CONTROL

    #ptc2013 | 11

    Alarm Priority = Critical

    Description = Waldo is

    on the loose

    Critical Alarm = SEVERE consequences requiring IMMEDIATE action

  • Technology Conference 2013

    FIND WALDO

    #ptc2013 | 12

    The system will shut down in seconds 7 6 5 4 3 2 1 0

  • Technology Conference 2013

    LETS GO TO GREY SCALE

    #ptc2013 | 13

  • Technology Conference 2013

    THERE HE IS

    #ptc2013 | 14

  • Technology Conference 2013

    APPROPRIATE USE OF COLOR

    Color is an attention getter.

    Use for the abnormal, not the normal.

    #ptc2013 | 15

  • Technology Conference 2013

    COLOR-BLIND VIEW

    ~6% of males in the US have certain amount of color blindness

    Can you tell which valves are open/closed?

    #ptc2013 | 16

  • Technology Conference 2013

    I SEE WALDO

    Reserve bright colors for abnormal situations.

    Which other measurement is getting close to alarm?

  • Technology Conference 2013

    CHECKPOINT

    Alarm Management alone is not enough for increased Human Reliability

    Graphics that support alarm management efforts are required

    Converting graphics to grey scale alone is not enough either

    High Performance Objects alone are not enough either

    Objective based design is a MUST for High Performance HMI

    High Performance HMI Development Work Process

    #ptc2013 | 45

  • Technology Conference 2013

    THREE PHASES OF AN HMI PROJECT

    Step 1: HP HMI Philosophy and Style Guide

    Step 2: Assess and benchmark existing graphics

    Step 3: Determine specific performance and goal objectives for the control of the process, for all modes of operation

    Step 4: Perform task analysis to determine the control manipulations needed to achieve the performance and goal objectives

    Step 5a: Design/sketch high performance graphics

    Step 5b: Build the designed graphics in the DCS

    Step 6: Install, commission, and provide training on the new HMI

    Step 7: Control, maintain, and periodically reassess the HMI performance

    #ptc2013 | 46

    Phase 1

    Phase 2

    Phase 3

  • Technology Conference 2013

    CHALLENGES

    Resistance to Change

    Graphics are usually designed in-house

    Defensive emotional responses

    Engineers are often unaware of deficiencies

    Operators are used to the old graphics

    Costs

    #ptc2013 | 47

    1990s

    June 29, 2007

  • Technology Conference 2013

    COST EFFECTIVE WAY TO MAKE A BIG DIFFERENCE

    DO ALL LEVEL 2 and LEVEL 1 Graphics first. Implement them, leaving the other existing graphics on the system.

    Consider all existing graphics as Level 3. Leave them but alter the navigation paths.

    Phase in any new Level 3 and 4 graphics over time as desired

    This is inconsistent and non-optimum but will accomplish a lot of the possible improvement.

    #ptc2013 | 48

  • Technology Conference 2013

    SUMMARY

    Traditional HMIs have been cited as contributing factors in industrial accidents

    Proper HMIs improve safety, reliability and production performance

    Benefits of High Performance HMI:

    Brings information in context to the console operators where they work

    Provides at a glance situational awareness

    Reduces training requirements

    Enables proactive intervention

    Minimizes shift variation

    Minimizes operator fatigue

    Increases Human Reliability

    Is now practical and achievable
