The touch panel is defined as being touched at the first touch point coordinate or a middle point between the first touch point coordinate and the second touch point coordinate, when the relative distance is less than a predetermined distance. The touch panel is defined as being touched at the first touch point coordinate and the second touch point coordinate, when the relative distance is greater than or equal to the predetermined distance.

  • Patent number: 8913040
    Abstract: A touch sensitive device having circuitry to compensate for crosstalk from the device display to the device touch sensor panel is disclosed. The crosstalk compensation circuitry can include a downsampler and a crosstalk compensator. The downsampler can downsample a display image to a manageable size for transmission and processing and can then send the downsampled image to the crosstalk compensator so as to provide information about the display operation that can be used to estimate the expected amount of crosstalk caused by the display. The crosstalk compensator can estimate the amount of crosstalk based on the downsampled image and can then compensate a touch image captured by the touch sensor panel for the estimated amount, the touch image being indicative of a touch or hover event at the panel.

  • Patent number: 8896561
    Abstract: A method for operating a data processing system to implement a gesture on a touch enabled display is disclosed. The method causes the data processing system to determine a position of a contact object on the touch-enabled display as a function of time. The data processing system provides an offset indicating a distance through which a point shown on the display is to be moved in response to the determined position. The offset has a first value in a normal mode and a second value in a precise gesture mode. The value in the precise gesture mode is less than the value in the normal mode. The data processing system automatically changes from the normal mode to the precise gesture mode in response to changes in the determined position as a function of time. Exemplary changes utilize changes in direction or the speed of motion of the contact object.
