Holographic Transmission Enables Real-time Transcontinental Telementoring and Teleteaching

Two proof-of-concept demonstrations achieved real-time, life-sized 3D holographic communication across continents for telementoring and teleteaching, with no perceptible delay. Barriers remain: high costs, limited infrastructure, and ethical concerns.

• Review and two proof-of-concept demonstrations: transcontinental surgical telementoring (Boston to São Paulo) and large-scale educational transmission (Mayo Clinic to G7 Summit).
• Both achieved seamless bidirectional volumetric communication without perceptible delay, showing immersive copresence for clinical and educational collaboration.
• Key limitations: high implementation costs, latency sensitivity, limited field of view, and digital infrastructure gaps in low-resource regions; not yet widely validated.
