From the beginning history of having paper, people have applied paper in the light of its

aesthetic and functional characteristics to achieve the works and technique of folk paper

art. The artistic charm contained in the folk paper art affected the artists. The artists

then made use of paper to be the media of performance. It has been ceaselessly created and

applied till now and produced the modern artistic paper art. The early animations used

paper art to be the procedure of display and development. Such paper art including

traditional background and cultural dimensions displayed more features with the combination

of digital techniques. The creation “Invisible Loneliness” took latchkey children as the

subject matter to display the latchkey children’s fear and loneliness in their hearts while

they were alone. It used the techniques of computer animation combined with the style of

paper art to create. Hopefully the audience could value and concern the children’s

psychological problems through surveying themselves after being busy all day.
