Most of the answers given by job seekers are: I close my eyes and feel it, pretending to be a blind person to describe to myself, as long as I can understand yellow, blind people will understand; tell him that yellow is the warm feeling of the sun on the body; Give him bananas and tell him that bananas are yellow...
In fact, if you think about it carefully, you will find that the title only gives half of the user's identity: invisible items. The other half is not clear: Congenital blind or acquired blind?
If he is born blind, it means that he has never seen yellow, let alone what yellow looks like; if he is acquired blind, he has known yellow before, but he has forgotten about yellow after becoming blind.
The difference between the two is: the former has never seen yellow and can only feel it through his senses; the latter can ask him which yellow objects he has an impression of, and help him awaken his memory by describing the objects.
Therefore, be sure to identify the user before answering the question. Only by first determining who to solve the problem can we better understand their needs and provide them with solutions.
Second, clarify the needs
Suppose the user is congenitally blind and has never seen yellow. Before you describe it for him, you need to clarify the second thing: why does he want to know about yellow? In what situations does he need to know about yellow? That is what we often say: needs and scenarios.
I assumed three requirements:
He wants to know which items are yellow
He wants to know about colors
he needs to identify yellow
Requirement 1: Want to know which items are yellow
The world of the blind is colorless, or that all objects are one color—black. They have no concept of color, they don't even know what color is.
But he may wish he was using Latest Mailing Database certain objects with color. For example, the next time he eats fruit, he will know that the bananas he eats and the oranges he peels are two colors. For such needs, the yellow items can be "classified" and then relayed.
The yellow of fruit, the yellow of sunlight, the yellow of autumn leaves, the yellow of gold medals, the yellow of grain, the yellow of flowers, the yellow of land... Although they are all yellow, the meanings expressed and the messages conveyed are different. "Category description" can make the other party's feelings about things more clear and accurate.
Just like the example mentioned above, if you tell him that sunflowers are yellow, the next time someone mentions sunflowers, he will know in his heart: oh ~ it is a yellow plant; if you tell him that corn is also yellow, he will think: oh ~ Grain the same color as sunflowers.
Requirement 2: Want to know about color
If he is just curious about colors and wants to know about colors, yellow is just one of them. The question then becomes: how to describe colors to blind people.
You can use other senses to let him experience different colors (including yellow), or you can use the "comparison" method to let him know that the world is colorful, and let him know that different colors feel different.
For example, the feeling brought by yellow:
Like a ray of sunshine in winter, warm and comfortable
Like a royal crown, noble and atmospheric
Like seeing the flickering lights in the distance in the desert in the middle of the night, it is hope and inspiration
It is also like stepping on the streets sprinkled with maple leaves in autumn, the sound of clack clack
Or the feeling of the autumn breeze blowing through the wheat fields
It's like the egg tart left on the corner of a child's mouth, sweet and crispy
It is also the softness of desert sand
Another example is the feeling brought by red:
It's like holding the hand of a sweetheart for the first time, and the little heart is thumping
It is also like the Spring Festival couplet posted in front of the gate of the New Year's Eve
It's like eating a chili pepper
Requirement 3: Need to identify yellow
There are fewer but more typical scenarios where blind people need to distinguish yellow, such as traffic lights.
