5. Key Points
key1.
Recognize the shape of what is shown in Line Drawing, and identify the light and dark areas in Grayscale Image. Then, by feeling color change and same color area in Color Picture, the thing is recognized by stepwise. However, complex images such as natural landscapes can have many lines, so in Line Drawing it is difficult to understand the shape.

key2.
Learn the relationship between voice and sound with touch, and by tracing slowly, you will feel the change in color due to the change in sound. If the same sound continues, it will be the same color area. If you do not understand the color, also touch and listen to the voice.

key3.
Voice and sounds will come out as much as you touch, so it may not correspond to the part you are looking at. Please slowly examine the pictures.

key4.
