WEARCOMP

• Constancy is both interactional and operational:
• Interactional Constancy:
  • Screen over one or both eyes at all times
  • keypad or the like conveniently accessible at any time.
• Operational Constancy:
  • Apparatus always ready.
  • may have ``sleep modes'' but it never ``dead''.
  • responds quickly to user-input
  • amenable to ephemeral bursts of thought, inspiriation, or the like
  • Example: offhand reference to word in dictionary
  • Example: sudden urge to grab snapshot picture of something seen in the last 30 seconds.
• Differs strongly from laptop computer which must be taken out, turned on, and booted up.
