Definition - The Gulfs - Intro to the Design of Everyday Things

  • 0:00 - 0:03
    Two sources of difficulty, when using your
  • 0:03 - 0:06
    product, are due to the lack of discoverability
  • 0:06 - 0:09
    and feedback, knowing what to do, then
  • 0:09 - 0:13
    wondering what happened. These two difficulties result from
  • 0:13 - 0:18
    the huge gulf between a person's goal and the means of achieving them, this is
  • 0:18 - 0:21
    called the gulf of execution. There's also the
  • 0:21 - 0:25
    gulf between assessing the state of the world,
  • 0:25 - 0:28
    and trying to determine if that state
  • 0:28 - 0:31
    matches the initial goal, and this is called
  • 0:31 - 0:34
    the gulf of evaluation. Figuring out what
  • 0:34 - 0:39
    actions are possible, during the gulf of execution,
  • 0:39 - 0:42
    is all about discoverability. And knowing what
  • 0:42 - 0:45
    just happened during the gulf of evaluation is
  • 0:45 - 0:51
    about feedback. Ever buy a new product and then not know how to work it?
  • 0:51 - 0:55
    Well, likely because it lacks discoverability. Ever
  • 0:55 - 0:58
    stand at an elevator or pedestrian traffic light?
  • 0:58 - 1:00
    Pushing the button, but not knowing if the
  • 1:00 - 1:03
    system noticed, so you push over and over
  • 1:03 - 1:08
    again, that's because of lack of feedback. The role of the designer is to help
  • 1:08 - 1:11
    people bridge the two gulfs, making the possible
  • 1:11 - 1:15
    actions discoverable and providing feedback along the way.
