A Virtual and Interactive Light-Art-Like Representation of Human Silhouette

Abstract

Light art represents various objects by a light stroke drawn in the air. It takes about 10 to 30 seconds to create a light art picture. We could create a light art movie by binding a set of pictures; however, it is a time-consuming task because we need a large number of frames to create a movie and difficult because a person would need to author a sequence of temporally consistent frames. To solve this problem, we are developing a virtual and interactive light-art-like system. This system extracts edges of human bodies from depth information and then applies a point-to-curve algorithm to mimic hand-drawn figures. Finally, the system applies neon-like drawing and a visual effect on the figures and displays them in real-time. This paper also introduces our artwork produced with this system, and a user evaluation that shows that the artwork conveyed happiness and excitement to the audience.
