Challenges in Implementing Low-Latency Holographic-Type Communication Systems

Area of Science:

• Computer Science
• Human-Computer Interaction
• Telecommunications

Background:

• Holographic-type communication (HTC) promises enhanced user engagement and spatial co-presence.
• Current HTC systems face stringent requirements, including multi-sensory data handling, lightweight processing, and low-latency transmission.
• Achieving realistic avatar embodiment and supporting numerous participants remain significant hurdles.

Purpose of the Study:

• To review and categorize the primary challenges hindering the widespread implementation of HTC systems.
• To propose a conceptual framework addressing key HTC system requirements.
• To enhance realism in human body appearance and dynamics within HTC.

Main Methods:

• Systematic review of current HTC system limitations.
• Categorization of challenges into major groups.
• Development of a conceptual framework for HTC realization.

Main Results:

• Identified key limitations in multi-sensory data, processing, transmission, avatar realism, and scalability.
• Proposed a framework to address low-latency, lightweight processing, and scalability.
• Aimed to improve the realism of human body appearance and dynamics in HTC.

Conclusions:

• Overcoming HTC system challenges is crucial for realizing its full potential.
• The proposed framework offers a pathway towards more efficient and realistic HTC.
• Future HTC development should focus on addressing identified limitations for broader adoption.
