Overview

• Nintendo submitted WIPO patent applications on Aug. 7–8 for Joy-Con 2 attachments featuring a crank accessory and a clickable wheel.
• The crank design uses a rotary disc tracked by the Joy-Con 2’s optical sensor through a window and mounts to the controller with two magnets.
• Rotation of the clickable wheel is captured by the mouse sensor via a gear train, with its primary click mapped to the SL button and a second button triggering the SR input.
• These filings extend earlier Joy-Con 2 mouse-mode sensor patents and echo mechanical ideas such as the Playdate handheld’s crank accessory.
• Nintendo has not indicated any commercial plans for the attachments, leaving their potential release and gameplay applications purely speculative.
