Inspired by their love of retro games, Professor Takayuki Hoshino and his team created the game to provide a real-time demonstration of their advances in nano-mixed reality (Nano MR) &#8211; the seamless integration of virtual objects (the game\u2019s \u201cspaceship\u201d and \u201cbullets\u201d) with extremely tiny, real physical objects (nano-scale polystyrene balls acting as \u201cenemies\u201d). Rather than just being a bit of Space Invaders-inspired fun, this technology has potential for some exciting real-life applications, especially in the field of medical treatment (Source: <a href=\"https:\/\/phys.org\/news\/2025-02-world-smallest-video-game-nanoscale.html\" target=\"_blank\" rel=\"noreferrer noopener\">phys.org<\/a>).&nbsp;<\/p>\n\n\n\n<p>The world\u2019s smallest shooting game is so tiny that it is completely invisible to the naked eye &#8211; in fact, it is nano-sized. For reference, nanoparticles are one millionth of a millimeter in diameter. Even your best pair of glasses is not going to help you get anywhere near to seeing this.&nbsp;&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"\u30ea\u30a2\u30eb\u306a\u30ca\u30ce\u7c92\u5b50\u3092\u81ea\u5728\u306b\u64cd\u4f5c\u3067\u304d\u308b\u4e16\u754c\u6700\u5c0fTV\u30b2\u30fc\u30e0\uff5e\u60c5\u5831\u7a7a\u9593\u3068\u7269\u7406\u7a7a\u9593\u3092\u3064\u306a\u3050\u8907\u5408\u73fe\u5b9f\u30c7\u30a3\u30b9\u30d7\u30ec\u30a4\u3092\u958b\u767a\uff5e\" width=\"1160\" height=\"653\" src=\"https:\/\/www.youtube.com\/embed\/1l1m24Wty00?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>As seen in Nagoya University\u2019s video above, a highly magnified projection was shown on a special display in real-time. The white, round shapes of differing sizes on the screen are actually physical microspheres, nano-sized balls of polystyrene, that are used as enemies. To manipulate these physical &#8220;enemies&#8221;, the researchers used high-speed electron beams. These super powerful beams can be used to generate dynamic patterns of electronic fields or optical images on a display surface.\u00a0\u00a0<\/p>\n\n\n\n<p>For this game, high-speed electron beams were used to form the player\u2019s triangular \u201cspaceship\u201d and its tiny \u201cbullets.\u201d The game controller was used to manipulate the scanning pattern of these electron beams, resulting in a playable game. The player can shoot electron beam \u201cbullets\u201d out of the tip of the ship. The video shows that these bullets have an actual impact on the nanoparticles, causing them to move around.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"1200\" height=\"673\" sizes=\"auto, (max-width: 1200px) 100vw, 1200px\" src=\"https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2025\/03\/20250305-45236-001.jpeg\" alt=\"Worlds smallest video game nano MR\" class=\"wp-image-45240\" style=\"width:670px;height:auto\" srcset=\"https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2025\/03\/20250305-45236-001.jpeg 1200w, https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2025\/03\/20250305-45236-001-380x213.jpeg 380w, https:\/\/automaton-media.com\/en\/wp-content\/uploads\/2025\/03\/20250305-45236-001-768x431.jpeg 768w\" \/><figcaption class=\"wp-element-caption\"><em>Diagram of the world&#8217;s smallest video game (Credit:\u00a0<a href=\"https:\/\/iopscience.iop.org\/article\/10.35848\/1347-4065\/ada707\" target=\"_blank\" rel=\"noreferrer noopener\">Japanese Journal of Applied Physics<\/a>\u00a0(2025).
