A machine translation of the full text of the patent describes the controller as "a novel input device that can be used as a mouse and other than a mouse." 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."

Interestingly, the patent also seems to conceive of a mouse mode for a more traditional controller. While the design of the device is rudimentary and still split in two like a Joy-Con, it is clearly one-half of a traditional gamepad with an optical sensor on the inside surface.
