Real-time Interaction and Motion Tracking in VR for Telerehabilitation (MoVE)

December 4, 2019 updated by: Qin Zhu, University of Wyoming

Developing Real-time Interaction and Motion Tracking in Immersive VR for Telerehabilitation

Current technology for telerehabilitation is limited to be audio- or video- based interaction without an objective and accurate measure of motor functions. A technology integrating motion tracking with 3D immersive virtual reality has been developed by an interdisciplinary team to shift the paradigm of telerehabilitation. We aim to take the significant step to develop the patient-centered telerehabilitation that will feature real-time patient-therapist interaction with functions of tele-monitoring, tele-diagnosis, and tele-therapy. Such an interactive telerehabilitation is expected to increase patient adherence to therapy and minimize the existing health disparities.

Study Overview

Detailed Description

By innovatively integrating the 3D motion tracking with 3D immersive virtual reality (VR), the real-time user interaction and simultaneous motion tracking and analysis in the immersive VR environment were made possible. We now propose to customize this technology for telerehabilitation. The ultimate goal is to build a VR-based interactive tele-rehab system that is patient-centered, with augmented feedback and tele-presence of therapist to assist rehabilitative exercises and recovery of motor functions in both real and virtual environment. To achieve this goal, we are specifically tackling three problems.

  • 1: Cross validating the precision of motion data captured in VR. We will modify our current software (Unity-based) so that it can work simultaneous with two motion tracking systems (Optical tracking and Magnetic tracking) to capture motion data in a 3D VR environment. The recorded data in our software will be compared and correlated with those data recorded by the two motion tracking systems in 3D for examination of accuracy.
  • 2: Building and testing the network code for remote data transmission and interaction. We will write network code to enable the remote transmission of motion tracking data between two sites. The latency of data transmission will be tested to determine the minimum speed of internet for implementing such a tele-rehab system.
  • 3: Designing and implementing a VR interaction task for remote monitoring and diagnosis. A 3D interactive VR task will be built for real-time local interaction and the remote monitoring, assessment and intervention.
