Nintendo’s Welcome Tour transforms system setup into sensory wizardry. The opening “Controller Lab” uses magnetic field sensors in the new Joy-Con (dubbed “Mice”) to detect micro-movements (0.1mm precision). Rotate them to assemble virtual Switch 2 components in 3D space, feeling HD Rumble 2.0 simulate screw tension and connector clicks. “Each interaction teaches hardware literacy,” says Lead UX Architect Kenji Yamamoto. The lab runs at 4K/120fps in docked mode – showcasing the Tegra T239’s ray-traced reflections on metallic parts.
