Development of IR Marker Positioning System

With recent developments in smartphones, wearable devices, and other consumer technology, efficiently measuring new types of human behavior, such as traffic flow of pedestrians, is possible. Existing indoor position tracking systems pose problems in terms of cost and accuracy. This study develops an indoor position tracking system. We propose a position tracking system that uses simple trigonometry to track the position of infrared markers. In this study, we report tests conducted on a prototype system to evaluate the usefulness of the proposed method. Our prototype could measure position with high accuracy, and the signal ID was always correctly recognized. This indicates that the proposed technique could be useful for obtaining traffic-flow data.
