The metaverse is expected to evolve into an immersive environment based on photorealistic stereoscopic imaging to integrate real and virtual worlds. To transition from flat images to immersive stereoscopic images, such as light fields and holograms, a continuous cycle of technological development should be reached in media, content, and device technologies, ranging from acquisition and generation to transmission and synthesis as well as reproduction and interaction. Additionally, owing to the multitude of components involved in the metaverse, proper service realization will be challenging without concurrent advancements in computing and communication technologies that facilitate the integration of such components. We introduce research and development trends in media, contents, and devices at the Electronics and Telecommunications Research Institute toward the next generation of stereoscopic images.
