Abstract: A finger-mounted device may include finger-mounted units. The finger-mounted units may each have a body that serves as a support structure for components such as force sensors, accelerometers, and other sensors and for haptic output devices. The body may have sidewall portions coupled by a portion that rests adjacent to a user's fingernail. The body may be formed from deformable material such as metal or may be formed from adjustable structures such as sliding body portions that are coupled to each other using magnetic attraction, springs, or other structures. The body of each finger-mounted unit may have a U-shaped cross-sectional profile that leaves the finger pad of each finger exposed when the body is coupled to a fingertip of a user's finger. Control circuitry may gather finger press input, lateral finger movement input, and finger tap input using the sensors and may provide haptic output using the haptic output device.

Abstract: An electronic device with a touch-sensitive surface, a display, and tactile output generator(s) displays a user interface including a moveable component representing a plurality of selectable options. The device detects a scroll input directed to the moveable component including movement of a contact followed by a lift-off. In response to detecting the scroll input: the device moves the moveable component through moving a first selectable option and a second selectable option, where the movement of the moveable component gradually slows down after the lift-off of the contact. As the first moveable component moves through the first selectable option with a speed: the device generates a tactile output and an audio output. As the moveable component moves through the second selectable option with a slower speed: the device generates a different tactile output in a first property but is the same in a second property and generates a different audio output.
