Observation: 3D projection and 'displays everywhere'

Readers may say that it is out of date. The author is paying attention to this form of '3D projection' recently. After watching the live performance 'ISAM Live' (video) performed by Amon Tobin using 3D projection mapping in the fall of 2012, I can't help but be impressed by the possibilities of this form of expression. 3D projection is a method of projecting images according to the shape of three-dimensional objects such as buildings, so that the three-dimensional objects present a deformation effect. By only letting the outline of the three-dimensional object shine, or changing the color and pattern, an image experience that is completely different from that of flat projection can be achieved. In Japan, the light show 'TOKYO STATION VISION' held at Tokyo Station Marunouchi Station Building in September 2012 made 3D projection widely known. I am a little embarrassed to say that I only learned about 3D projection at that time. For the current 3D projection, including detecting the accurate shape of the three-dimensional object as the projected object, adjusting the output of the projector according to the shape, etc., it is very important to perform settings and adjustments meticulously in advance. But I think that the idea of u200bu200b'feeding back the shape of the projected object to the output of the projector' can be used for various purposes. One of them is 'displays everywhere.' Portable projectors and short-throw projectors may bring about an era where display screens are everywhere. If they are combined with the idea of u200bu200b3D projection, the quality of the experience may be greatly improved. If the projector can have the following functions: (1) Use distance image sensors and other devices to detect the accurate shape of the projection object; (2) Detect the position of the user’s point of view; (3) Combine the shape of the projected object and the position of the user’s point of view to adjust the output ( Which color is projected to which pixel), for the user viewing the image, the world in which the entire space is like a display screen is close at hand. If you can use the camera to detect the color and surface state of the projected object, and adjust the color of each pixel output, the image quality may be further improved. To make it a reality, there are still many technical problems to be solved, and the demand for 'displays everywhere' is uncertain. However, like the 'Transparent Prius' developed by Masahiko Inami, a professor of the Graduate School of Media Design at Keio University, applications that need to use natural methods to project images on ordinary objects are constantly emerging. I believe that one day, a world where 'adaptive projectors' equipped with cameras, distance image sensors and advanced image processing functions will be used in various scenarios will come.
