All of them involve varying degrees of depth. All this can be recorded with SignWriting, but not with English gloss. Written English uses abstract symbols to record sound. SignWriting writes a visual language in a visual way. It is directly connected to what you see when you sign, so it is easily learned by children.
Children have enough problems learning to read and write English correctly.
English gloss systems can confuse the picture by trying to explain one language with the other. With SignWriting for ASL, and English for English, the two languages are whole and pure. It is our experience that children learn to read English better when they have both languages written on paper correctly. Please feel free to write if you have questions.
