Abstract: Techniques for identifying and discriminating between different types of contacts to a multi-touch touch-screen device are described. Illustrative contact types include fingertips, thumbs, palms and cheeks. By way of example, thumb contacts may be distinguished from fingertip contacts using a patch eccentricity parameter. In addition, by non-linearly deemphasizing pixels in a touch-surface image, a reliable means of distinguishing between large objects (e.g., palms) from smaller objects (e.g., fingertips, thumbs and a stylus) is described.

Abstract: Negative pixel compensation in a touch sensor panel is disclosed. The panel can compensate for a negative pixel effect in touch signal outputs due to poor grounding of an object touching the panel. To do so, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and compute a composite image from the captured image and the reconstructed image to replace the captured image. In addition or alternatively, the panel can reconstruct a captured touch image to remove negative pixel values indicative of the negative pixel effect and replace the captured image with the reconstructed image.

Abstract: Techniques for identifying and discriminating between different input patterns to a multi-touch touch-screen device are described. By way of example, large objects hovering a short distance from the touch-surface (e.g., a cheek, thigh or chest) may be identified and distinguished from physical contacts to the surface. In addition, rough contacts due to, for example, ears and earlobes, may be similarly identified and distinguished from contacts due to fingers, thumbs, palms and finger clasps.

Abstract: A method for performing multi-touch (MT) data fusion is disclosed in which multiple touch inputs occurring at about the same time are received to generating first touch data. Secondary sense data can then be combined with the first touch data to perform operations on an electronic device. The first touch data and the secondary sense data can be time-aligned and interpreted in a time-coherent manner. The first touch data can be refined in accordance with the secondary sense data, or alternatively, the secondary sense data can be interpreted in accordance with the first touch data. Additionally, the first touch data and the secondary sense data can be combined to create a new command.

Abstract: The selective rejection of touch contacts in an edge region of a touch sensor panel is disclosed. In addition, by providing certain exceptions to the rejection of edge contacts, the functionality of the touch sensor panel can be maximized. Contacts in edge bands around the perimeter of a touch sensor panel can be ignored. However, if a contact in the edge band moves beyond a threshold distance or speed, it can be recognized as part of a gesture. To accommodate different finger sizes, the size of the edge band can be modified based on the identification of the finger or thumb. Furthermore, if contacts in the center region of a touch sensor panel track the movement of contacts in the edge band, the contacts in the edge band can be recognized as part of a gesture.

Abstract: “Real-world” gestures such as hand or finger movements/orientations that are generally recognized to mean certain things (e.g., an “OK” hand signal generally indicates an affirmative response) can be interpreted by a touch or hover sensitive device to more efficiently and accurately effect intended operations. These gestures can include, but are not limited to, “OK gestures,” “grasp everything gestures,” “stamp of approval gestures,” “circle select gestures,” “X to delete gestures,” “knock to inquire gestures,” “hitchhiker directional gestures,” and “shape gestures.” In addition, gestures can be used to provide identification and allow or deny access to applications, files, and the like.

Abstract: Gestures for converting from a position control mode to a motion continuation mode are disclosed. A position control mode can be invoked when the user simultaneously places two or more fingers upon a sensor panel. The fingers can then be moved around to effect position control. A motion continuation mode can be invoked when one or more fingers are lifted off (but at least one finger remains in contact with the sensor panel). If the motion continuation mode is invoked, a virtual control ring can be generated, and scrolling of the viewable area or dragging of the cursor or object can continue in a particular direction specified by a velocity vector pointed in the direction of finger movement at the time the motion continuation mode is invoked, and having a magnitude proportional to the velocity of the finger at the time the motion continuation mode was invoked.

Abstract: The dynamic adjusting of the conditions for identifying inputs as touching a touch-sensitive device is discloses. In some examples, in addition to using a signal density make threshold to identify an input patch as touching the surface, a signal density stability threshold can be used to identify the input patch as touching the surface. In some examples, a weighted average of peak signal density contributions from recent identified touches can be computed to dynamically adjust the make threshold for new input patches. In other examples, a new input patch identified as associated with the same path as an earlier touch can have its “make” threshold dynamically adjusted based on the earlier touch without computing a weighted average.

Abstract: Embodiments are related to user input devices that accept complex user input including a combination of touch and push (or pick) input. Embodiments of the invention provide for selective ignoring or rejection of input received from such devices in order to avoid interpreting unintentional user actions as commands. Furthermore, some input signals can be modified. The selective rejection or modification can be performed by the user interface device itself or by a computing device that includes or is attached to the user interface device. The selective rejection or modification may be performed by a module that processes input signals, performs the necessary rejections and modifications and sends revised input signals to higher level modules.
