This paper presents a sensor fusion algorithm based on an unscented Kalman filter (UKF)
designed for robust estimation of position and orientation of a freely moving target in surgical …

Optical tracking provides relatively high accuracy over a large workspace but requires line-of-
sight between the camera and the markers, which may be difficult to maintain in actual …

Virtual Reality is widely regarded as an extremely promising solution for industrial training
purposes, as it allows to perform simulated hands-on activities in a controlled and safe …

This paper proposes an approach for velocity and position estimation through acceleration
measurements. In this approach, the noises of acceleration signal are removed through a …

Surgical navigation systems can overlay medical images on the patients and help surgeons
obtain surgical information in operations through motion tracking and fusion display. To …

Head tracking is primarily linked to the motion of the head and employed to locate and
update the coordinates of the head positions. Locating a point in 3-D requires both position …

Immersive Virtual Environments are extremely powerful tools; they allow to build worlds
whose only limit is the imagination. They are not only useful to artists letting their creativity …

With more and more autonomous mobile robots being used for the tasks constrained by
uncertainties, there is a need to utilize the on-board sensors to estimate the robot's states to …

In this paper, we propose a robust position tracking method using information fusion of an
optical sensor and inertial sensor. The proposed method is developed for tracking of …
