In Nintendo Switch™ Sports, players compete against each other in a series of user-friendly motion-controlled sports games using a simple setup: Joy-Con controllers and a screen. One challenge was to make sure that the player’s movements are accurately aligned with the avatar’s on-screen forward-facing position without having to rely on any kind of additional tracking system. Working in close collaboration with the system software and game development teams in Japan, NERD developed a custom sensor fusion algorithm uniquely tailored to the game, allowing players to swing their sword or racket with a higher sense of immersion in sports like Chambara or Badminton.
