Abstract:
A force-sensitive input device for receiving user input. The input device can include a contact (e.g., touch) sensor and a plurality of force sensors. By combining the information from a multi-touch event with information from each of the plurality of force sensors, a contact centroid and a force centroid can be determined. Thereafter, by projecting a vector defining the force applied to the input device onto a vector defined between the contact centroid and an individual contact location, a magnitude of force applied at that contact location can be approximated.
Abstract:
An electronic device includes a touch-sensitive surface. The electronic device includes one or more sensors to detect intensity of contacts with the touch-sensitive surface. The device detects a first touch input on the touch-sensitive surface, and, in response to detecting the first touch input on the touch-sensitive surface, determines a first intensity applied by the first touch input on the touch-sensitive surface. The device identifies a first intensity model identifier from a plurality of predefined intensity model identifiers, and, in accordance with the first intensity applied by the first touch input on the touch-sensitive surface and one or more thresholds associated with the first intensity model identifier, determines a first touch characterization parameter. Subsequent to determining the first touch characterization parameter, the device sends first touch information to the first software application. The first touch information includes the first intensity model identifier and the first touch characterization parameter.
Abstract:
An electronic device detects a change in intensity of an input on an input element that includes detecting an increase in intensity followed by a decrease in intensity, and determines whether the first decrease in intensity of the input meets up-click detection criteria, which require that the intensity of the input decrease below a first up-click intensity threshold in order for the up-click detection criteria to be met. The first up-click intensity threshold is time varying, in accordance with the detected intensity of the input during the first decrease in intensity of the input. If the first decrease in intensity of the input meets the up-click detection criteria, first feedback is provided, indicating that the first decrease in intensity of the input was recognized as an up-click, and if the first decrease in intensity of the input does not meet the up-click detection criteria, the first feedback is not provided.

An electronic device provides, to a display, data to present a user interface that includes: a plurality of user interface objects, and a current focus on a first user interface object. The device receives an input that corresponds to a gesture detected on a touch-sensitive surface of a user input device. The gesture includes a movement of a contact across the touch-sensitive surface followed by a lift-off of the contact from the touch-sensitive surface. The gesture includes a characteristic movement distance and a characteristic movement speed. In accordance with a determination that the gesture satisfies coasting criteria, the device moves the current focus in the user interface; and decelerates movement of the current focus across the series of user interface objects at a first deceleration rate that is based on: the characteristic movement distance of the gesture, and the characteristic movement speed of the gesture.

An electronic device displays a user interface of a first software application that includes one or more draggable objects and one or more control objects; and, detects a contact on a touch-sensitive surface at a first location while a focus selector is displayed over a first draggable object and a movement of the contact across the touch-sensitive surface to a second location that corresponds to a first control object. In accordance with a determination that the contact at the first location satisfies object selection criteria, the device moves the first draggable object to the first control object in accordance with the movement of the contact across the touch-sensitive surface to the first control object. In accordance with a determination that the contact at the second location satisfies first intensity criteria, the device performs a first predetermined operation that corresponds to activation of the first control object.
Abstract:
An electronic device detects a first touch input on a first touch region of a touch-sensitive surface, and identifies a first intensity model identifier associated with the first touch region. In response to detecting the first touch input, the device determines a first intensity of the first touch input on the first touch region; determines a first touch characterization parameter; and, subsequently sends to a first software application the first touch characterization parameter. The device also detects a second touch input on a second touch region of the touch-sensitive surface, and identifies a second intensity model identifier associated with the second touch region. In response to detecting the second touch input, the device determines a second intensity of the second touch input on the second touch region; determines a second touch characterization parameter; and, subsequently sends to the first software application the second touch characterization parameter.
Abstract:
An electronic device with a display, a touch-sensitive surface, and one or more sensors that detect intensities of contacts on the touch-sensitive surface displays, on the display, a user interface. While displaying the user interface, the electronic device detects an input that includes a contact on the touch-sensitive surface. In response to detecting the input while displaying the user interface, and while continuing to detect the input on the touch-sensitive surface: If an intensity of the contact satisfies an activation intensity threshold, the electronic device performs a first operation associated with the activation intensity threshold. The activation intensity threshold is determined based on whether or not prior inputs by the user on the touch-sensitive surface exceed a respective intensity threshold. If an intensity of the contact does not satisfy an activation intensity threshold, the electronic device forgoes performing the first operation associated with the activation intensity threshold.
Abstract:
An electronic device provides, to a display, data to present a user interface that includes a plurality of user interface objects, and a current focus on a first user interface object. While the display is presenting the user interface, the electronic device receives an input that corresponds to a movement of a contact across on a touch-sensitive surface. The electronic device, in response to receiving the input and in accordance with a determination that a first axis is a dominant axis, moves the current focus along the first axis by a first amount and along the second axis by a second amount. The amount of movement of the current focus along the second axis is reduced to a first non-zero amount by a scaling factor that is based on one or more inputs received prior to receiving the input.
