NHK「WORLD-JAPAN」さんのインスタグラム動画 - (NHK「WORLD-JAPAN」Instagram)「🏄‍♂️Learning how to surf? Trouble standing up? Kazme Egawa, a once-discouraged surfer and student of computer science at the University of Tokyo graduate school, is developing a surfboard, called a jellyboard, that he hopes will help beginners stick with learning how to surf. Built-in sensors detect the board’s movements, triggering flashing LED lights that tell surfers if they’re gaining/losing speed, when to stand and which direction to go. He’s hoping it will put a spotlight on Japanese surfing at the 2020 Olympics.🏄‍♀️ See more: NHK WORLD-JAPAN - News. . . #surf #surfing #LEDlights #japaneseinvention #letsgosurfing #learningtosurf #surftech #grommet #surfinginjapan #surfboard #2020olympics #japan #instagramjapan #nhkworld #nhkworldnews #nhkworldjapan #nhk」6月27日 17時34分
