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

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)

Existing power-related ISO/IECGraphical Symbols
For Use On Equipment
Can you identify and define each of these?

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
