摘要： Techniques for identifying an object in close proximity to, but not in contact with, a multi-touch touch-screen device are described. By way of example, a cheek or ear hovering a short distance from the touch-surface (e.g., approximately 1 to 3 centimeters) may be identified and distinguished from physical contacts to the surface.

摘要： 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. In one implementation, a unique technique to reduce the noise in segmented image peripheral pixels.

摘要： A touch sensor panel is disclosed. The touch sensor panel includes a plurality of rows, at least one of the rows being a split row including a plurality of row subsections; and a plurality of columns, at least one of the columns being a split column including a plurality of column subsections. The touch sensor panel is configured with at least one split row and at least one split column located to increase a likelihood that a touch anywhere on the touch sensor panel overlaps with at least one split row and at least one split column. The rows and columns are individually charged electrodes capable of detecting a change in capacitance in a corresponding area of the touch sensor panel.

摘要： Compensation of pixels that generate erroneous readings (so-called “negative pixels”), produced when multiple touch events are generated by the same poorly grounded object on a touch sensor panel is disclosed. To minimize negative pixels, a thicker cover material and/or a lower dielectric constant can be used. Alternatively, narrower drive and sense lines can be employed. To compensate for negative pixels, a predicted negative pixel value can be computed as an indicator of pixels that are likely to be distorted. The negative pixel value for any particular pixel can be computing by summing up the touch output values for pixels in the drive line of that pixel, summing up the touch output values for pixels in the sense line of that pixel, and then multiplying these two sums. The predicted negative pixel value is added to the measured touch output value for the pixel to compensate for artificially negative readings.

摘要： Selection of input of a touch sensing surface is provided. Contacts on or near a surface are tracked to obtain touch information of the contacts. A first gesture is detected corresponding to first touch information of a number of contacts performing an activity, and a first input corresponding to the first gesture is selected. A second gesture is detected corresponding to second touch information of a number of contacts performing an activity. A determination of whether to select a second input corresponding to the second gesture is made. The second input is selected if third information satisfies a predetermined criteria, and the first input is maintained if the third information does not satisfy the predetermined criteria.

摘要： 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.
