Observation of Human Activities Based on Spatial Memory in Intelligent Space

Abstract

Intelligent Space (iSpace) we propose as an intelligent environment provides information and physical services to users via intelligent agents such as mobile robots, computer devices, and digital equipment. A suitable human interface is needed to enable users to operate agents in iSpace. For this, we previously proposed spatial memory. Here, we have improved system functions to make it more widely applicable. Specifically, we present four spatial memory problems and discuss solutions, focusing on user authentication, for which we propose a new procedure using spatial memory. By introducing the spatial human interface in iSpace, we also observe human activity in the environment via the history of human interface use involving several experiments.
