Sustainable memory system using global and conical spaces

We present a concept and implementation of a computational support for spatial memory management and describe its temporal evolution. Our essential idea is to use an immersible globe that consists of a global space and a conical space, thereby providing arbitrary memory space for humans. We developed a sustainable knowledge globe (SKG) for constructing a memory space, and proposed a system called Contents Garden to expand the SKG into immersive space. We carried out the user study of SKG to evaluate its effectiveness. We also proposed and discussed three perceptual operations on Contents Garden to improve the operativity of the SKG.
