Ruge’s Summary of Foxlin’s Shoe-Mounted Sensors
Pedestrian Tracking with Shoe-Mounted Inertial Sensors
This article discusses the procedures and uses for a proprietary location sensor. The sensor used is installed in/on a users shoe, and utilizes foot movements and orientation combined with various other sensors to not only gain a user’s current location, but track the operators movement as well. This is accomplished by using common orientation and momentum sensors in tandem with multiple other possible sensors and combining the data-sources together. The paper discusses the advanced math and probably concepts that are involved such a task.
The most applicable portions of this paper were the methods used to integrate technology. The author understands that no one solution is the best for tracking movement. GPS has high error rates and low accuracy, mounted sensors often are uncomfortable and inhibit the users dexterity, and RF and sonic systems often require preinstalled infrastructure. The NavShoe is designed to integrate with software capable of taking information from GPS, the environment, or logical motion paths to correct and improve the accuracy of the information gathered from the device. The same concept and even some of the technical details for this product could be reapplied to many other concepts and Augmented Reality applications. Perhaps they may be applied to integrate other tools as well, such as range finding, multiple GPS, or even WiFi connections to assist in the information tracking. The paper also didn’t discus integrating multiple sensors on multiple feet to better predict strides and resting legs.
