Joy-Con 2 Mouse/Gyro Mode Switching and Gyro Correction

Patent publication US 20260288257 describes the mouse/gyro mode switching and gyro correction for Joy-Con 2.

  • Gyro switching to mouse (img below): the mouse sensor hole is blocked AND the long axis is roughly horizontal
Drawing from patent publication US 20260288257: FIG. 5 illustrates a first example according to an exemplary embodiment
  • Mouse switching to gyro (img below): the mouse sensor hole is unblocked AND the long axis tilts to 30°
Drawing from patent publication US20260288257: FIG. 8 illustrates a second example according to the exemplary embodiment
  • During mouse operation, gyro drift may accumulate; so when switching to gyro mode, the cursor may not align with the controller’s pointing direction (img 1 below)
  • Thus, a gyro correction is performed when switching from mouse to gyro (img 2): rotate forward axis to match long axis, and flatten the pointing direction
Drawing from patent publication US 20260288257: FIG. 7 illustrates a non-limiting example of a case in which gyro correction is not performed in the first example according to the exemplary embodiment
Drawing from patent publication US20260288257: FIG. 12 shows a non-limiting example of a flowchart of information processing.
