  It is difficult to design a visually appealing layout for common users, which
takes time even for professional designers. In this paper, we present an
interactive layout design system with shadow guidance and layout retrieval to
help users obtain satisfactory design results. This study focuses in particular
on the design of academic presentation slides. The user may refer to the shadow
guidance as a heat map, which is the layout distribution of our gathered data
set, using the suggested shadow guidance. The suggested system is data-driven,
allowing users to analyze the design data naturally. The layout may then be
edited by the user to finalize the layout design. We validated the suggested
interface in our user study by comparing it with common design interfaces. The
findings show that the suggested interface may achieve high retrieval accuracy
while simultaneously offering a pleasant user experience.
