Hall of Shame

• Cluttered display and lack of color makes it
  difficult to decipher the display
• Labels are not obvious
• Trying to fit too much info in small area

6

• Poor feedback on display, icons not explained
• Mapping is not clear, though car diagram is
  there, not much is used around the picture except
  trunk and hood, the car is more of just a picture
• There is a large gulf of evaluation, determining
  the state is difficult because of the unclear
  labels

A dialogue

  Tell me your four-digit delivery number or enter
  it on the keypad.
• Caller 4-8-3-3
• System 4-8-3-3 Is that right?
• Caller Yes.
• System OK, hold on(logs into system)What's
  your status? You can say arrived, departed or
  delayed.
• Caller I'll be delayed two days. There's a big
  storm.
• System Oh, sorry to hear that! Let me confirm. I
  have delivery number 4-8-3-3 delayed for 48 hours
  due to weather. Is that right?
• Caller Yes it is.

Categorizations of error

  edFinal2004-10-30.pdf
• clues the system gives the user (intentionally or
  otherwise) that a recognition error may have
  occurred. There are six of these explicit
  confirmation, implicit confirmation, reject, aid,
  non sequitur, and system repeat.
