This paper attempts to improve on SpaceTop, a system proposed by Jinha et al. that combines two-dimensional and three-dimensional operations. In addition, SpaceTop is a large-scale system with depth cameras and other devices installed on walls and ceilings, making it difficult to develop applications as a personal computer for ordinary use. The Laptop SpaceTop proposed in this paper is an inexpensive version of the SpaceTop, and it has been improved so that it can be folded up like a laptop computer and can be used on battery power.
