Student Perceptions of Superimposed Mixed Reality Anatomy: A Bridge Between the Virtual and Physical

Area of Science:

• Medical Education
• Anatomy Visualization
• Mixed Reality Technology

Background:

• Traditional anatomy education relies on cadavers and 2D diagrams, which have limitations in visualizing 3D structures and muscle attachments.
• Developing innovative pedagogical tools is crucial for enhancing medical student comprehension of complex anatomical relationships.

Purpose of the Study:

• To develop and evaluate a novel mixed reality (MR) learning model for musculoskeletal anatomy.
• To assess the effectiveness of superimposed 3D holograms with tactile feedback for anatomical learning.

Main Methods:

• A prototype MR model was created, integrating 3D holographic musculoskeletal anatomy with a physical skeleton.
• Tactile sensation was incorporated to represent bony attachments of muscles visualized virtually.
• Fifty-three second-year medical students participated in a pilot study, using the MR model for learning.

Main Results:

• The MR model successfully superimposed 3D anatomical holograms onto a physical skeleton.
• Students reported experiencing tactile sensations corresponding to muscle-bone attachments.
• Initial feedback indicated the format's potential as an effective learning modality.

Conclusions:

• The developed mixed reality model offers a promising new method for teaching musculoskeletal anatomy.
• Integrating virtual 3D anatomy with physical models and tactile feedback enhances the learning experience.
• Further research is warranted to validate the long-term educational impact of this innovative approach.
