Using Project Starline, two people in a distant place are communicating

　The PROJECT STARLINE: A HIGH-FIDELITY TELEPRESENCE SYSTEM published by Google Research research teams in the United States, "PROJECT STARLLINE SECTEM" announced in "Google I/O 2021" in May 2021.It is written in detail the mechanism.Project Starline is a system that acquire each other's upper body and keeps displaying in real time on the opponent's display away as a 3D model.[Image] At the beginning of the appearance of the prototype appearance, it became a hot topic that communication could be communicated with a high realism as if the opponent was in front of you.The paper also describes it as "displayed as if a person in a remote location is physically present."The author is 17, and it can be said that Google's effort is high.The biggest feature of Project Starline is that it uses a flat display as an extension of the video conference, not the VR / AR space.Eliminates the discomfort of wearing HMD and headphones, and can participate in a natural body like conventional physical meetings.The chair is fixed and the two are seated so that the eyes are met.The distance between the opponent's eyes is on the border between personal and social space 1.It is 25m.Simply displaying the upper body on the display will break the lower body and the tip of the arm at the bottom of the display, giving a sense of incongruity over the screen.So, 0 in front of the display.A desk -like shelf (written as Middle Wall) was installed at a 59m position so that the bottom of the display was invisible.In this method, the display has alleviated and the depth has increased.Hardware is a display, camera, speaker, microphone, lighting fixtures, computers, and other "display unit", and "backlight unit" equipped with infrared backlights and benches where people sit.Configure with devices.The main sensors to be maintained in the display unit are as follows.At the top of the display is a monochrome tracking camera, an infrared light, an infrared projector, a stereo camera, and a color camera.On the side of the display is a monochrome tracking camera and speaker.The lower part of the display (Middle Wall) is equipped with a color camera, a stereo camera, an infrared projector, and a microphone.
