  • Publication number: 20190034032
    Abstract: An image jaggedness filter is disclosed that can be used to detect the presence of ungrounded objects such as water droplets or coins, and delay periodic baseline adjustments until these objects are no longer present. To do otherwise could produce inaccurate normalized baseline sensor output values. The application of a global baseline offset is also disclosed to quickly modify the sensor offset values to account for conditions such as rapid temperature changes. Background pixels not part of any touch regions can be used to detect changes to no-touch sensor output values and globally modify the sensor offset values accordingly. The use of motion dominance ratios and axis domination confidence values is also disclosed to improve the accuracy of locking onto dominant motion components as part of gesture recognition.

  • Patent number: 10185432
    Abstract: This relates to a method of extrapolating proximity information to generate a border column or row of touch nodes (also known as touch pixels) and then fitting an ellipse to the contact patch including the extrapolated border touch nodes. Additionally, a contact can be identified as a thumb based on both its major axis and its distance to an edge of the touch sensing surface.

  • Patent number: 10175805
    Abstract: The application of a watershed algorithm to pixels and their touch values obtained from a scan of a touch sensor panel to determine patches corresponding to images of touch is disclosed. Prior to applying the watershed algorithm, background pixels having little or no touch values can be eliminated. A primary merge algorithm can then merge adjacent patches together when the saddle point between them is shallow as compared to the peak represented by the patches. However, if two candidate patches for merging have a total number of pixels below a certain threshold, these two patches may not be merged under the assumption that the patches might have been caused by different fingertips. Conversely, if two candidate patches for merging have a total number of pixels above a certain threshold, these two patches can be merged under the assumption that the patches were caused by a single thumb or palm.

  • Publication number: 20180299938
    Abstract: This relates to an event sensing device that includes an event sensing panel and is able to dynamically change the granularity of the panel according to present needs. Thus, the granularity of the panel can differ at different times of operation. Furthermore, the granularity of specific areas of the panel can also be dynamically changed, so that different areas feature different granularities at a given time. This also relates to panels that feature different inherent granularities in different portions thereof. These panels can be designed, for example, by placing more stimulus and/or data lines in different portions of the panel, thus ensuring different densities of pixels in the different portions. Optionally, these embodiments can also include the dynamic granularity changing features noted above.

  • Publication number: 20180275820
    Abstract: The use of multiple stimulation signals having one or more frequencies and one or more 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 one or more 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 one or more selected frequencies can be used to simultaneously stimulate the rows of the touch sensor panel, and the one or more mixers in each sense channel can be configured to demodulate the signal received from the column connected to each sense channel using the one or more selected frequencies. After all steps have been completed, the demodulated signals from the one or more mixers can be used in calculations to determine an image of touch for the touch sensor panel at each of the one or more frequencies.

  • Publication number: 20180150152
    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.

  • Publication number: 20180059928
    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.

  • Publication number: 20180024693
    Abstract: The rejection of undesired touch events on a touch surface is disclosed. A weighted meta-centroid of all touch events can be computed. In some examples, touches can be weighted inversely to their size and distance to the nearest neighboring touch. In some examples, touches can be weighted based on the size of their minor radii. A meta-ellipse can be fit to the weighted touch events. In some examples, the major axis of the meta-ellipse can be used to determine the orientation of a user's hand to reject undesired touches. In other examples, touches within the meta-ellipse can be rejected.

  • Patent number: 9874975
    Abstract: Reconstruction of an original touch image from a differential touch image is disclosed. Reconstruction can include aligning columns of the differential touch image relative to each other and aligning the image to a baseline DC value. The column and baseline alignment can be based on the differential image data indicative of no touch or hover, because such data can more clearly show the amount of alignment needed to reconstruct the original image. The reconstruction can be performed using the differential image data alone. The reconstruction can also be performed using the differential image data and common mode data indicative of the missing image column average.

  • Patent number: 9870137
    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.
