Spatial Memory as an Aid System for Human Activity in Intelligent Space

This paper presents the spatial memory that aids human activities in a working environment. The spatial memory enables humans to store computerized information into the real world by assigning a 3-D position as the memory address. By storing computerized information into the real world, users can manipulate the information in similar ways as physical objects. Consequently, we can retrieve stored knowledge by indicating the point using our own arms, which we name "human indicator." This paper shows a prototype of the spatial memory system, which has potential to enhance desk work. The implemented system is evaluated through two types of experiments by using human subjects. Experimental results verify the efficiency and the effectiveness of our spatial memory framework based on a statistical test
