    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: Pre-stored no-touch or no-hover (no-event) sensor output values can initially be used when a sensor panel subsystem is first booted up to establish an initial baseline of sensor output values unaffected by fingers or other objects touching or hovering over the sensor panel during boot-up. This initial baseline can then be normalized so that each sensor generates the same output value for a given amount of touch or hover, providing a uniform response across the sensor panel and enabling subsequent touch or hover events to be more easily detected. After the initial normalization process is complete, the pre-stored baseline can be discarded in favor of a newly captured no-event baseline that may be more accurate than the pre-stored baseline due to temperature or other variations.

    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: 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 detection of finger pinch, rotate, and tap gestures along with a translation and optionally liftoff motion to initiate certain actions is disclosed. To detect both the gesture and the translation, a certain amount of gesture scaling speed can be detected along with a certain amount of translation speed and distance traveled. For a finger pinch gesture, the scaling speed can be computed as the dot product of the velocity vectors of two or more fingers coming together. For a finger rotation gesture, the scaling speed can be computed as a cross product of the velocity vectors of the rotating fingers. The translation speed of a gesture can be computed as the average of the velocity vectors of any fingers involved in the gesture. The amount of gesture scaling speed and translation speed needed to trigger the recognition of a combined gesture with translation can be a predetermined ratio.

    Abstract translation: 公开了手指捏合，旋转和敲击手势以及平移以及可选地提升运动以发起某些动作的检测。 为了检测手势和翻译，可以检测一定量的手势缩放速度以及一定量的平移速度和旅行距离。 对于手指捏捏手势，缩放速度可以计算为两个或更多个手指的速度矢量的一部分的积积。 对于手指旋转手势，缩放速度可以被计算为旋转手指的速度矢量的交叉乘积。 手势的翻译速度可以计算为手势中涉及的任何手指的速度向量的平均值。 触发识别组合手势所需的手势缩放速度和平移速度的量可以是预定的比例。

    Abstract: The use of multiple stimulation frequencies and phases to generate an image of touch on a touch sensor panel is disclosed. Each of a plurality of sense channels can be coupled to a column in a touch sensor panel and can have multiple mixers. Each mixer in the sense channel can utilize a circuit capable generating a demodulation frequency of a particular frequency. At each of multiple steps, various phases of selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the multiple mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the selected frequencies. After all steps have been completed, the demodulated signals from the multiple mixers can be used in calculations to determine an image of touch for the touch sensor panel at each frequency.
