Tracking of users using systems like GPS has many useful applications. However it also suffers from issues like inaccuracy in exact positioning and uncertainty of the exact path being and to be followed by the user. The paper discusses an approach towards pedestrian tracking using shoe-mounted inertial sensors. The NavShoe concept performs robust tracking with […]
Pedestrian Tracking with Shoe-Mounted Inertial Sensors InterSense developed NavShoe, which can track the user wearing a shoe on which a small inertial sensor is adapted, on the contrary to previous devices that required a specific environment. Thus, the location and the orientation of the user can be known. The usual problem is the horizontal acceleration […]
Pedestrian Tracking Tracking a person is a challenging problem especially in outdoor environments that have to previous preparation. This capability would prove very useful for things like search and rescue, as well as tracking emergency response workers (like firefighters). The NavShoe is a concept attempting to address this problem by using a small motion sensor […]
In this paper, the author describes NavShoe, a novel shoe-mounted inertial sensor system that is capable of tracking 6-DOF in an un-instrumented environment. The proposed system builds on the prevalent MEMS gyroscopes that report 3-DOF (orientation in space) by also providing highly accurate position estimates. Un-instrumented inertial tracking is made feasible by the identification of alternating stationary and moving […]
In this paper, the author introduces a navigation system called NavShoe, developed by InterSense. Currently, orientation tracking is not very challenging because earth’s gravity and geomagnetic field can help sensors make good judgement. However position tracking is not that simple. It has to rely on radio-navigation aids or some other infrastructure. The appearance of NavShoe […]
The author starts the paper with stating the needs for tracking with Shoe-Mounted sensors. The main issue with traditional tracking framework is that it required the system to be instrumented to result in a tracking with reasonable error. To effectively track without prepared instruments, the author came up with an inertial tracking system called NavShoe. […]
NavShoe is a position tracking system, small enough to truck into shoe laces. It is much more accurate than head mounted inertia orientation tracker because the higher foot acceleration enables the use of transfer alignment from GPS. InterSense InertiaCube3 was used to get multisensory data such as gyro, accelerometer, and magnetometer. Calibration of sensors is […]
The paper describes a navigation system, NavShoe, that tracts the location of a person with a device that is small enough to be tucked under the shoelaces of a shoe. A system like this would be extremely useful in many different applications such as emergency responders. Two categories of experiments were done to test the […]
The paper highlights the problems faced by modern day navigation and tracking systems. They then introduce NavShoe a device that provides accurate tracking as well as orientation feedback. The major hurdle faced by such trackers is to maintain the accuracy with both orientation and position. Position tracking is based on inertial sensing but it is […]

The paper highlights some of the existing issues with location based tracking systems in a real world MR and wearable systems, that it requires the objects in the environment to be pre-mapped or marked thus not making the system extensible and robust. Computer vision tracking poses a lot of challenges and requires complex algorithms and […]
Navshoe is new kind of tracking technology that is used to track motion of a user in the real world. The basic design is small device with various sensors is placed in the shoe of the user. The device is GPS capable but by now means requires GPS to function. It combines a few different […]
The current GPSs cannot track the real position without prepare the environment with markers or instrument. The NavShoe device can overcome this problem by providing an inertial sensing. The NavShoe allows to correct the velocity error by applying a zero velocity into an EKF navigation error corrector when a foot is in stance phase. A […]
