Title: ENERGY STAR Monitor MOU, v3


1
ENERGY STAR Monitor MOU, v3
  • Introduce Active Power Criterion
  • watts 30 20 megapixels
  • Reduce / Consolidate Sleep ( 4 W)
  • Introduce Off Power ( 2 W)
  • Strongly Recommend UI Standards
  • ENERGY STAR / TCO meeting next week

Overview
  • Background
  • Energy
  • Controls
  • Scope
  • Standard
  • Static
  • Dynamic
  • Future Issues

4
Office Equipment Energy UseAnnual Electricity
(TWh/year)
No Power Management Now (ENERGY
STAR) Potential(100 Enabling)
2.2 billion
1.3 billion
5
Problem
  • Existing Power Management Controls are
  • Hidden, Confusing, Absent
  • Power Management Enabling Rates Low

6
Solution
  • Create broadly similar interfaces for power/power
    management control across all office equipment
    and consumer electronics
  • Accomplish this by creating a voluntary standard
    for interface elements

7
Office EquipmentThe Standby Problem
  • Suspend mode is know as standby mode under the
    Microsoft Windows 98 operating system. For
    systems with ACPI compliance, suspend mode is
    known as sleep mode (Dell)
  • Stand-by mode - Fully ready to copy but not
    copying. (ASTM Copier Test Procedure)
  • Stand-by - an optional operating state of
    minimal power reduction (VESA Standard)
  • Standby power - The lowest power mode in which
    the appliance is plugged in (LBNL-Leaking/Standb
    y Electricity)
  • Standby is the lowest power state where the
    system is responsive to interrupts (PowerPC
    Reference Platform)
  • Suspend is currently ignored under Windows 95/98
    and Windows 2000 because terminology is
    ill-defined (Microsoft)
  • There is no distinction between Suspend in OnNow
    as there was previously under APM definitions
    (Microsoft)

8
Existing power-related ISO/IECGraphical Symbols
For Use On Equipment
Can you identify and define each of these?
9
Overall Plan
  • Assess Existing Devices
  • Develop New Standards (Voluntary)
  • Market these to Institutions
  • Manufacturers (PAC)
  • International Standards Organizations
  • Industry Institutions

10
Topics High Priority, 1
  • Basic symbols and switches buttons
  • Basic indicators
  • Changing power states
  • Transition indicators
  • Underlying archetype of power management
    behavior, including basic terms

11
Topics High Priority, 2
  • Controlled and controlling devices
  • Remote indicators and controls
  • Composite devices and diversity of low-power
    modes
  • Power management schemes
  • Behavior based on wake event type
  • Linked behavior
  • Interactions with non-power modes

12
TopicsMedium/Low Priority
  • Disability
  • Culture
  • Temporary changes
  • System status after power failure
  • Terminology
  • Language
  • Batteries
  • Role of the term ENERGY STAR
  • Self-monitoring
  • Miscellaneous

13
Three Basic StatesOn, Off, Sleep
  • Within a state, device has consistent capability,
    behavior (e.g. state change)
  • May have more states, but all mapped into forms
    of the basic three

14
The Term Power
  • For indicators, switches/buttons
  • Need standard translation
  • Possible international word (voice)

15
Power Symbols
  • Drop as a symbol.
  • Change meaning of from Standby to
    Power
  • Symbols and/or Indicators

16
Indicators
  • Use Green / Amber / Off for On / Sleep / Off
  • Blinking only for transitions or non-power
    meanings
  • Possible standard (optional) audio indications

17
SleepMetaphor and Symbol
  • Sleep is most compelling metaphor, and has
    clear extensions (e.g. waking up).
  • is already common and seems clear

18
Hibernate
  • Hibernate is a form of Off
  • Need a new term

19
PC Sample State Diagram
20
Device Behavior(Dynamic)
  • Taxonomy of device types
  • User expectations
  • Device feedback
  • Consistency
  • Remote controls, indicators

21
Bottom Line for Displays
  • for Power button / indicator
  • Green / Amber / Off for power indicator
  • Blinking for transitions
  • Dimming?
  • Accessibility?

22
Emerging Issues (Displays)
  • Display as portal
  • OLD input ? PC ? Display
  • NEW input ? Display ? PC
  • Multiple PCs
  • Remote PCs (closet)
  • Indicator / Power button on display

23
Emerging Issues (Displays)
  • More input devices in monitor
  • Tablet PCs, etc.
  • Occupancy / Proximity sensors
  • Voice
  • Secondary displays
  • Adjacent
  • Distant
