Close to the secret of the tiny ○ × △ □ engraved on the PS5 controller and accessories

On the surface of DualSense, which is a dedicated controller for PS5, 40,000 PlayStation symbols called ○ × △ □ are engraved. Since the symbol ○ × △ □ is a fine unevenness on the surface of the controller, it also contributes to 'ease of grip'.
At first glance, you can't find ○ × △ □ other than the button part, but ...
If you look closely at the white part of the controller, you can see the tiny ○ × △ □ icons lined up as shown in the picture below.
Two people, Yuto Morisawa and Ken Igarashi, who were the chief designers of PS5 and Dual Sense, told The Verge about this impressive design. The ○ × △ □ icons are three-dimensionally engraved, and the icons are not evenly spaced. The reason is that the base design is hand sketched.
According to Mr. Morisawa, texture design started with handwritten sketches, digitized, mockups were created, prototypes were created, and the final product version was completed. During this process, the development team repeated the tests until they found a satisfactory balance. This 'convincing balance' seems to be the density and tactile sensation of ○ × △ □ in the texture design, and it seems that adjustments have been made to make the texture look good, comfortable and non-slip. ..
As for which texture to use, not only the appearance but also the feel was emphasized, so it seems that the process of touching and confirming the actual prototype was emphasized.
Also, even with the same texture, by creating about 4 patterns of engraving height, the one with the best feel is pursued.
The surface texture of DualSense is divided into two layers, which cannot be seen with the naked eye. When you actually check the surface of the controller with a microscope, it looks like this. The icon is engraved on the icon, and you can see that the icons with slightly different heights are arranged so that they overlap.
However, The Verge cites 'easy to get dirty' as a drawback of the texture.
The white plastic parts with the texture are injection molded. In other words, the mold for injection molding is engraved with fine irregularities of ○ × △ □. In order to accurately engrave the shape of ○ × △ □ on the entire curved surface, the mold is engraved using a laser, and according to Mr. Igarashi, 'a high-end multi-axis laser engraving machine that is difficult to obtain' It seems that the mold was processed using it.
The texture of ○ × △ □ is used not only for DualSense but also for PS5 exclusive accessories such as PS5
