Spatial memory for collaboration support system in intelligent space -User identification based on spatial memory-
Mihoko Niitsuma, Hideki Hashimoto · 2007
This paper presents an implementation of the spatial memory system for supporting collaboration activity in Intelligent Space. in this paper, a design of the new spatial memory system is described based on three requirements for a collaboration system: (1) sharing information for multi-users and multi-terminals, (2) access privileges for SKTs and (3) user identification. User identification method is one of the most important fuctions for sharing information systems. Therefore, this paper proposes a new user identification method by using the spatial memory system. More specifically, users create their own key-Spatial-Knowledge-Tags (SKTs) as passwords to use the spatial memory system. The new user identification method is evaluated through user experiments. Experimental results show high effectiveness of the method.
