How Apple Watches Use a Rotating Dial to Navigate Menus
A method for using a physical rotating dial on a device to scroll through lists and menus while providing audio feedback for accessibility.
Original patent title: “Screenreader user interface”
A method for using a physical rotating dial on a device to scroll through lists and menus while providing audio feedback for accessibility. Granted to Apple Inc in 2019 with 63 claims and 8 forward citations.
Key facts
Coverage
What does this patent actually cover?
This patent describes how a physical rotating input mechanism, like the Digital Crown on an Apple Watch, interacts with a software interface. When a user turns the dial, the device moves a visual highlight between items in a list and simultaneously plays a sound associated with the new item. A key feature is the non-linear relationship between the dial's movement and the menu scrolling; turning the dial faster can skip more items than turning it slowly. The system also distinguishes between when this navigation mode is active and when it is not, ensuring the dial only controls the menu when specifically intended.
The gap
What does this patent NOT cover?
- Does not cover touch-based scrolling that does not involve a physical rotating mechanism.
- Does not cover navigation systems that use linear sliders or buttons instead of a rotatable dial.
- Does not cover volume control gestures that do not involve the specific rotary navigation mode described.
- Does not cover voice-command-only navigation interfaces.
These exclusions are unique to PatentBrief — derived from the actual claim language, not patent-office boilerplate.
What made this novel
The system maps the physical rotation of a dial to a non-linear software response, allowing for both precise, item-by-item navigation and rapid scrolling depending on the speed of the user's input.
