Enhanced location tracking in sensor fusion-assisted virtual reality micro-manipulation environments

Abstract

Virtual reality (VR) technology plays a significant role in many biomedical applications. These VR scenarios increase the valuable experience of tasks requiring great accuracy with human subjects. Unfortunately, commercial VR controllers have large positioning errors in a micro-manipulation task. Here, we propose a VR-based framework along with a sensor fusion algorithm to improve the microposition tracking performance of a microsurgical tool. To the best of our knowledge, this is the first application of Kalman filter in a millimeter scale VR environment, by using the position data between the VR controller and an inertial measuring device. This study builds and tests two cases: (1) without sensor fusion tracking and (2) location tracking with active sensor fusion. The static and dynamic experiments demonstrate that the Kalman filter can provide greater precision during micro-manipulation in small scale VR scenarios.

Research on the functional game industry expandable based on VR realistic technology

“…Industrial integration refers to the dynamic development process in which different industries or different industries within the same industry interpenetrate and intersect with each other, eventually merging into one and gradually forming new industries [17][18][19]. Industrial fusion is a form of industrial innovation, and the proliferation of this industrial innovation method drives the adjustment and upgrading of the related industrial structure [20][21][22][23].…”
