Abstract: Electronic devices may use touch pads that have touch sensor arrays, force sensors, and actuators for providing tactile feedback. A touch pad may be mounted in a computer housing. The touch pad may have a rectangular planar touch pad member that has a glass layer covered with ink and contains a capacitive touch sensor array. Force sensors may be mounted under each of the four corners of the rectangular planar touch pad member. The force sensors may be used to measure how much force is applied to the surface of the planar touch pad member by a user. Processed force sensor signals may indicate the presence of button activity such as press and release events. In response to detected button activity or other activity in the device, actuator drive signals may be generated for controlling the actuator. The user may supply settings to adjust signal processing and tactile feedback parameters.

Abstract: Improved capacitive touch and hover sensing with a sensor array is provided. An AC ground shield positioned behind the sensor array and stimulated with signals of the same waveform as the signals driving the sensor array may concentrate the electric field extending from the sensor array and enhance hover sensing capability. The hover position and/or height of an object that is nearby, but not directly above, a touch surface of the sensor array, e.g., in the border area at the end of a touch screen, may be determined using capacitive measurements of sensors near the end of the sensor array by fitting the measurements to a model. Other improvements relate to the joint operation of touch and hover sensing, such as determining when and how to perform touch sensing, hover sensing, both touch and hover sensing, or neither.

Abstract: Devices having one or more sensors located outside a viewing area of a touch screen display are disclosed. The one or more sensors can be located behind an opaque mask area of the device; the opaque mask area extending between the sides of a housing of the device and viewing area of the touch screen display. In addition, the sensors located behind the mask can be separate from a touch sensor panel used to detect objects on or near the touch screen display, and can be used to enhance or provide additional functionality to the device. For example, a device having a sensor located outside the viewing area can be used to detect objects in proximity to a functional component incorporated in the device, such as an ear piece (i.e., speaker for outputting sound). The sensor can also output a signal indicating a level of detection which may be interpreted by a controller of the device as a level of proximity of an object to the functional component.

Abstract: User interface changes related to moving items in a user interface are disclosed. An operation (e.g., a drag operation) can be initiated on selected items by moving a cursor or pointing device in the user interface, and an animation can be presented illustrating representations of the selected items moving from their respective original locations toward a current location of the cursor or pointing device and forming a cluster in proximity to the current location of the cursor or pointing device. As the cluster of items is moved over a container object in the user interface, the representations of the items can adopt the appearance style defined by that container object. The representations of the items can also be shown to depart from the cluster and move toward anticipated locations of the items in the container object as a preview of a drop operation into the container object.

Abstract: Touch and hover switching is disclosed. A touch and hover sensing device can switch between a touch mode and a hover mode. During a touch mode, the device can be switched to sense one or more objects touching the device.

In response to detecting the gesture, when the contact has an intensity above the selection intensity threshold, the device selects at least a portion of the content in accordance with the movement of the focus selector over the content.

Abstract: While in a first mode, a first electronic device displays on a touch-sensitive display a first application view that corresponds to a first application. In response to detecting a first input, the electronic device enters a second mode, and concurrently displays in a first predefined area an initial group of application icons with at least a portion of the first application view adjacent to the first predefined area. While in the second mode, in response to detecting a first touch gesture on an application icon that corresponds to a second application, the electronic device displays a popup view corresponding to a full-screen-width view of the second application on a second electronic device. In response to detecting one or more second touch gestures within the popup view, the electronic device performs an action in the second application that updates a state of the second application.

Abstract: Detecting a signal from a touch and hover sensing device, in which the signal can be indicative of concurrent touch events and/or hover events, is disclosed. A touch event can indicate an object touching the device. A hover event can indicate an object hovering over the device. The touch and hover sensing device can ensure that a desired hover event is not masked by an incidental touch event, e.g., a hand holding the device, by compensating for the touch event in the detected signal that represents both events. Conversely, when both a hover event and a touch event are desired, the touch and hover sensing device can ensure that both events are detected by adjusting the device sensors and/or the detected signal. The touch and hover sensing device can also detect concurrent hover events by identifying multiple peaks in the detected signal, each peak corresponding to a position of a hovering object.
