Current implementations of spatially-aware multi-surface environments rely heavily on instrumenting the room with different tracking technologies (e.g. Microsoft Kinect, Vicon Cameras). Prior research, however, has shown that real-world deployment using such approaches leads to feasibility issues and users being uncomfortable with the technology in the environment. In this work, we attempt to a...

Walking underwater reduces joint impacts, enhances stability and lowers the net body weight of patient during rehabilitation. It is a recent rehabilitation method few suitable methods exist to study gait kinematics. We propose an inertial measurement (IMU) system analogous those used in land-based investigate The objective this was test validate proposed two human trials by evaluating knee angl...

We propose a new position regulation strategy for VTOL-UAVs using IMU and GPS measurements. Since there is no sensor that measures the attitude, our approach does not rely on the knowledge (or reconstruction) of the system orientation as usually done in the existing literature. Instead, IMU and GPS measurements are directly incorporated in the control law. An important feature of the proposed s...

In recent years, security of autonomous vehicles is emerging as popular research topics. Especially, autonomous vehicles are equipped with many sensors such as GPS, IMU, wheel encoders and some of them are vulnerable to the attack, such as spoofing. Our objective is to detect and classify attacks of the right encoder sensor by using variables of GPS, IMU, two wheel encoder sensors. We also anal...

This research studies the reduction and the estimation of the noise level within a redundant configuration of low-cost (MEMS-type) inertial measurement units (IMUs). Firstly, independent observations between units and sensors are assumed and the theoretical decrease in the system noise level is analyzed in an experiment with four MEMS-IMU triads. Then, more complex scenarios are presented in wh...

The Department of Mechanical Engineering and Avionics Engineering Center at Ohio University are developing an electromechanical system for the calibration of an inertial measurement unit (IMU) using global positioning system (GPS) antennas. The GPS antennas and IMU are mounted to a common platform to be oriented in the angular roll, pitch, and yaw motions. Vertical motion is also included to te...

This paper introduces a method for the robust estimation of foot clearance during walking, using a single inertial measurement unit (IMU) placed on the subject's foot. The proposed solution is based on double integration and drift cancellation of foot acceleration signals. The method is insensitive to misalignment of IMU axes with respect to foot axes. Details are provided regarding calibration...

Techniques are described in the following paper to incorporate a GPS with an IMU sensor to produce more accurate positions and attitude dynamics for geo-reference images of roadways. An Extended Kalman Filter (EKF) provides the possibility to integrate values from the two sources whilst minimizing errors to provide an accurate trajectory of the vehicle. Preliminary tests have shown that the use...

A smart munition revolves by 2~3Hz when it flights. Before guidance starts, the roll estimation of a smart munition is an important factor to improve the navigation performance. The roll estimation algorithm is already known using IMU and GPS. But GPS can’t be available as a measurement under GPS jamming environment. This paper explains how to estimate the roll angle of a smart munition under j...
