Area of Science:

  • Medical Informatics
  • Computer Science
  • Human-Computer Interaction

Background:

  • Extended Reality (XR) technology offers potential for enhancing telemedicine.
  • Transferring 3D patient data enables more immersive virtual reality (VR) and augmented reality (AR) experiences.

Purpose of the Study:

  • To propose an XR-based telemedicine collaboration system utilizing 3D patient avatars.
  • To improve remote clinical collaboration by creating shared XR spaces.

Main Methods:

  • Developed an XR system with AR (Microsoft HoloLens 2) and VR (HTC Vive Pro) clients.
  • Implemented 3D patient avatar creation using 3D body pose estimation from camera input.
  • Utilized WebRTC for audio and video streaming.

Main Results:

  • The system successfully creates a 3D patient avatar without complex 3D body reconstruction.
  • Clinicians can interact with the avatar and perform 3D annotations.
  • Performance evaluation demonstrated high frame rates and acceptable processing latency.

Conclusions:

  • The proposed XR telemedicine system effectively uses 3D body pose estimation for avatar creation, simplifying the technology.
  • The novel architecture reduces system complexity and resource requirements.
  • The system facilitates enhanced collaboration between local and remote clinicians.
