Instructions

The following activity will demonstrate how visual content can supplement text to create a better experience for users, including those with cognitive disabilities.

  1. 找一张空白的纸。
  2. If it isn't already perfectly square, cut off one edge of the paper until it is perfectly square.
  3. Fold the paper in half diagonally.
  4. Lay the paper down in front of you so that the longest edge is facing you.
  5. Take the bottom left corner and fold it over the main area of the piece of paper so that the corner touches the opposite edge, and so that the top of the newly folded edge is parallel with the bottom of the piece of paper.
  6. Do the same thing to the right corner, folding it across the main area of the piece of paper until it touches the opposite edge. The top edge of this fold should be exactly on top of the top edge of the previous fold.
  7. Take the outer layer of the very top corner and fold it down until the corner touches the spot where the bottom of the other two folds meet. You should see a pattern in the shape of an "X."
  8. Do the same thing to the other layer, but in the opposite direction.
  9. 将两层分开在顶部,轻轻推动侧面。
  10. You made an origami cup! (Or did you?)

Questions and Discussion

  • 你在执行任务时如何成功?
  • Were you able to make anything resembling a cup?
  • Are you sure that you performed the task correctly? Perhaps you made a mistake or two, whether you know it or not.

Here's what your origami cup should look like:

How closely does your origami cup match the one pictured above? Is it even close? If not, why not?

Although you may have been able to complete the task by simply reading the instructions, you may have become confused at some point. The instructions may have seemed ambiguous or poorly written. Perhaps you misunderstood an instruction without realizing it.

  • 在开始任务之前,它是否有助于在最终目标的图片?
  • Would it have helped to see someone perform the task, or an illustration of how to perform the task?

Note

The following example presents visual content that will not be of use to people who cannot see it, but we have provided a brief discussion of this material in theNote About Visual Disabilitiessection.

将书面说明与视觉指令进行比较:

  • Example 1: Simple step-by step instructions on how to fold an origami cup, illustrated with arrows and other visual cues showing how to fold the paper.

After looking at the above visual methods of giving instructions on the task:

  • Is it easier to perform the task?
  • Which instructional method did you like best?
  • Can you think of other instructional methods that may be even better?

如何涉及认知残疾人

Visually-oriented readers were at a cognitive disadvantage when trying to fold an origami cup with nothing more than written instructions. Individuals with learning disabilities, reading disorders, or more profound cognitive disabilities often feel similarly disadvantaged when trying to understand concepts that are difficult for them.

内容需要清晰准确,有时以多种格式,为这些人完全理解。在折纸杯的示例中,插图和动画是特别有用的。利用其他类型的信息,音频内容可能更合适。

Important

In many cases, the techniques for making web content accessible to people with cognitive disabilities are nothing more than techniques for effective communication.

Understanding this principle, making content accessible to people with cognitive disabilities becomes less mysterious, albeit challenging. Designing for people with cognitive disabilities isn't so much an art or a science, but a craft: We are applying creativity to create a tool that widest audience will use to accomplish a task.

Note About Visual Disabilities

Keep the needs of both people with visual disabilities and people with cognitive disabilities in mind. If illustrations are provided for people with cognitive disabilities, add alternative text for users with visual disabilities. Likewise, videos need accessible captions and transcripts. In the case of the origami cup, more detailed instructions would probably need to be written for a blind person to be able to perform the task. These detailed instructions would be the "text alternative" to the illustration format. With both illustrations and detailed textual instructions, both audiences would receive what they need.
