Immersive video interaction system:a surveyOA

As communication technologies undergo rapid evolution,human interaction technologies have become increasingly efficient and accessible.Videoconferencing,for example,facilitates real-time,face-to-face communication worldwide,providing unprecedented convenience.Nevertheless,traditional two-dimensional(2D)videoconferencing systems frequently fall short of delivering a fully immersive experience,as they lack the ability to convey physical presence,depth perception,and natural interaction—key elements that are of particular significance in replicating the subtleties inherent in in-person communication.This disconnection leaves users yearning for the rich,multi-sensory experiences that real-life interactions can offer.In response,significant research efforts have been dedicated to the development of immersive video interaction systems(IVISs).This paper introduces the concept of IVISs and reviews a spectrum of systems advanced by researchers and industry innovators,each of whom contributes unique insights into the evolution of this field.A comparative analysis of the characteristics of current IVISs is provided,offering insights across multiple dimensions.This survey concludes with a discussion of potential future research directions and the challenges that remain in enhancing the IVIS technology.Through a comprehensive analysis,this work aims to foster further exploration and innovation in immersive communication technologies.
