The purpose of this study is to clarify the effects of several conditions of human tracing by using a slipper-type RFID reader system, especially we focused attention on the sticking interval and layout of RFID tags laid on the floor and route of walk. And we also verify the availability of this system.
According to the results, "Equilateral Triangle Grid" is more suitable than “Square Grid”, because of "Square Grid" doesn't catch curve movement easily. And also, the trace accuracy of free walking in this system becomes about α=0.8, when we assume the sticking layout to be "Equilateral Triangle Grid", the sticking interval to be "300(mm)", the antenna installation position to be "Heel" and the size of antenna to be "Large".
This was thought to be in the range of practical use, and it was clarified that this system was an effective method for the tracing of human walk.
