Abstract:
Apparatuses and methods for an electronic device to control the application of friction to a rotary input control with a shaft. In one example, the apparatus may include a spring bar member having a first surface and a second surface, the first surface positioned adjacent to the shaft; and a movable tension member positioned to engage the second surface of the spring bar; wherein as the tension member engages the spring bar, the spring bar engages the shaft and applies a frictional force to the shaft. In this manner, the apparatus can controllably apply a friction force of a desired amount to the rotary input control.
Abstract:
The computing system includes a primary display, memory, and a housing at least partially containing a physical in put mechanism and a touch screen adjacent to the physical input mechanism: displays, on the primary display, a first user interface, the first user interface comprising one or more user interface elements; and identifies an active user interface element among the one or more user interface elements that is in focus on the primary display. In accordance with a determination that the active user interface element that is in focus on the primary display is associated with an application executed by the computing system, the computing system displays a second user interface on the touch screen, including: (A) a first set of corresponding to the application; and (B) at least one system-level affordance corresponding a system-level functionality.
