Abstract: Controlling virtual objects displayed on a display device includes controlling display, on a display device, of multiple virtual objects, each of the multiple virtual objects being capable of movement based on a first type of input and being capable of alteration based on a second type of input that is different than the first type of input, the alteration being different from movement. A subset of the multiple virtual objects as candidates for restriction is identified, and based on identifying the subset of virtual objects as candidates for restriction, a responsiveness to the first type of input for the subset of virtual objects is restricted. The first type of input applied to a first virtual object included in the subset of virtual objects and a second virtual object included in the multiple virtual objects is detected, with the second virtual object being excluded from the subset of virtual objects.

Abstract: Objects displayed on a display component of a multi-touch display device may be assigned to and displayed at various visual layers, with each visual layer corresponding to a different depth relative to a foreground (or background) of the display component of the multi-touch display device. One or more annotations may be generated in response to user interaction with the multi-touch display device, with each annotation being assigned to an appropriate visual layer.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for input classification for multi-touch systems. In one aspect, a method includes receiving data describing a first region of contact with a touch sensitive display, a second region of contact with the touch sensitive display, and a third region of contact with the touch sensitive display, the second region of contact being separate from the first region of contact and the third region of contact being separate from the first region of contact and the second region of contact.

The method includes classifying the second region of contact as incidental touch input provided by a user's resting body part. The method includes classifying the third region of contact as a stylus input.

Abstract: Methods and systems for interfacing with multi-input devices employ various techniques for controlling the window framing of images. Such techniques provide control, including moving, sizing, and orientating, of one or more displayed window frames in which one or more images are displayed.

Abstract: A graphical user interface is rendered on a display screen of a touch screen device. The display screen includes a display area for rendering images, and the graphical user interface of the application is rendered in a portion of the display area. Digital touch data is generated in response to user interactions with a touch-sensitive surface of the touch screen device. the digital touch data into OS touch events and application touch events. The OS touch events, application touch events, and application location information are received at a system hook. The application location information identifies the portion of the display area of the touch screen device in which the graphical user interface of the application is rendered. The system hook filters the OS touch events and the application touch events based on the application location information and provides the filtered OS touch events and application touch events to the application.

Abstract: A display device comprises a display panel including a display region configured to display one or more image objects and an overscan region configured to prevent the display of images within the overscan region, a touchscreen panel overlying the display region and the overscan region configured to detect and generate engagement data indicative of detected engagement, and a computer processor configured to access first engagement data, determine that the first engagement data reflects engagement with at least one portion of the touchscreen panel correspondingly overlapping with the overscan region, identify a first particular engagement input type based on the first engagement data, and instruct the display panel to invoke the display of the one or more image objects in the display region or to change the display of the one or more image objects in the display region.

Abstract: Placement by one or more input mechanisms of a touch point on a multi-touch display device that is displaying a three-dimensional object is detected. A two-dimensional location of the touch point on the multi-touch display device is determined, and the touch point is matched with a three-dimensional contact point on a surface of the three-dimensional object that is projected for display onto the image plane of the camera at the two-dimensional location of the touch point. A change in applied pressure at the touch point is detected, and a target depth value for the contact point is determined based on the change in applied pressure. A solver is used to calculate a three-dimensional transformation of the three-dimensional object using an algorithm that reduces a difference between a depth value of the contact point after object transformation and the target depth value.

The display screen includes a display area for rendering images, and the graphical user interface of the application is rendered in a portion of the display area. Digital touch data is generated in response to user interactions with a touch-sensitive surface of the touch screen device.

Abstract: A multi-touch display device that is configured to display multiple objects concurrently and that provides multi-touch controls for manipulating multiple of the displayed objects with multiple degrees of freedom concurrently but independently is configured to reduce the degrees of freedom provided by the manipulation controls for at least two of the displayed objects in response to detecting that an input mechanism is exerting control over the two displayed objects concurrently.

Abstract: First and second objects are displayed on a pressure-sensitive touch-screen display device. An intersection is detected between the objects. Contact by one or more input mechanisms is detected in a region that corresponds to the first displayed object. Pressure applied by at least one input mechanisms is sensed. The depth of the first displayed object is adjusted as a function of the sensed pressure. The depth of the displayed objects are determined at their detected intersection. The determined depths of the displayed objects are compared. Based on a result of comparing the determined depths, data is stored indicating that one of the displayed objects is overlapping the other. In addition, the displayed objects are displayed such that the overlapping displayed object is displayed closer to a foreground of the pressure-sensitive touch-screen display device than the other displayed object.

Abstract: A three-dimensional data set is accessed. A two-dimensional plane is defined that intersects a space defined by the three-dimensional data set. The two-dimensional plane defines a two-dimensional data set within the three-dimensional data set and divides the three-dimensional data set into first and second subsets. A three-dimensional view based on the three-dimensional data set is rendered on such that at least a portion of the first subset of the three-dimensional data set is removed and at least a portion of the two-dimensional data set is displayed. A two-dimensional view of a first subset of the two-dimensional data set also is rendered. Controls are provided that enable visual navigation through the three-dimensional data set by engaging points on the multi-touch display device that correspond to either the three-dimensional view based on the three-dimensional data set and/or the two-dimensional view of the first subset of the two-dimensional data set.
