Now, a newly published patent filed by Nintendo seems to confirm that feature and describes how it will work.The international patent was filed with the World Intellectual Property Organization in January 2023, but it was only published on WIPO's website on Thursday. The Japanese-language patentwhose illustrations match what we've seen of Switch 2 Joy-Con preciselyfeatures an English abstract describing "a sensor for mouse operation" that can "detect reflected light from a detected surface, the light changing by moving over the detected surface..." much like any number of optical computer mice. Schematic drawings in the patent show how the light source and light sensor are squeezed inside the Joy-Con, with a built-in lens for directing the light to and from each.

In mouse mode, as described in the patent, the user cradles the outer edge of the controller with their palm and places the inner edge "on, for example, a desk or the like."In this configuration, the user's thumb can still access the analog stick (which is now pointing horizontally) while the index and middle fingers are positioned so the two shoulder buttons "can be operated as, for example, a right-click button and a left-click button," according to the patent. The patent describes this configuration as "easy to hold" or "easy to grip." It also goes to great lengths to explain how the shoulder buttons wrap around the curved top corner of the controller and thus are "easy to press" by pushing either downward or closer to horizontally with a finger.According to the patent, two Joy-Cons can be used simultaneously as mice, with one in each hand, or one can be used as a mouse while the other is held vertically as a more traditional Switch Joy-Con. Intriguingly, the patent suggests that the mouse mode might work when the controller is hovering up to 1 cm above the flat surface being used, which would put it at the higher end of usable lift-off distances used in PC gaming mice.

For instance, the patent makes no mention of the stabilizing mounts that were shown clicking onto the edge of the Joy-Con before a mouse-like sliding section of the hardware's first-glimpse trailer last month.That said, the patent serves as strong evidence of just how the Switch Joy-Cons could emulate computer mice. We expect more details will be shared when Nintendo releases a Switch-focused Direct video on April 2.Kyle OrlandSenior Gaming EditorKyle OrlandSenior Gaming Editor Kyle Orland has been the Senior Gaming Editor at Ars Technica since 2012, writing primarily about the business, tech, and culture behind video games.
