    Abstract: An electronic device may include a touch screen electronic display configured to offset and/or shift the contact locations of touch implements and/or displayed content based on one or more calculated parallax values. The parallax values may be associated with the viewing angle of an operator relative to the display of the electronic device. In various embodiments, the parallax value(s) may be calculated using three-dimensional location sensors, an angle of inclination of a touch implement, and/or one or more displayed calibration objects. Parallax values may be utilized to remap contact locations by a touch implement, shift and/or offset displayed content, and/or perform other transformations as described herein. A stereoscopically displayed content may be offset such that a default display plane is coplanar with a touch surface rather than a display surface. Contacts by a finger may be remapped using portions of the contact region and/or a centroid of the contact region.

Run-time signals are acquired from X-Y nodes across the panel at the time of a touch event. One or more run-time signal values may be substituted into the panel characteristic model to determine a distance between an X-Y node most strongly associated with the run-time touch event and a point-of-projection of the touch event location onto the path.

After the pixel of the original image is copied to the pixel of the destination image, the height of the pixel of the original image is decremented. The pixel of the original image is copied in the rightward direction to pixels of the destination image until the height of the pixel of the original image becomes 0 or until a height of the pixel of the destination image becomes lower than that of the pixel of the original image. The same processes are performed on each pixel of the original image, and thereby the left-eye image is generated.

  • Publication number: 20140160085
    Abstract: In various aspects a host processor and a touchscreen controller may concurrently process a signal sent by a touch transducer when a touch is detected. A touch signal sent directly from a touch transducer may be formatted into a calibrated touch signal that the host processor can process. The calibrated touch signal may allow the host processor to receive and process touch signals from transducers and touchscreens from various manufacturers. The touchscreen controller and the host processor may each independently assess the touch-processing state. The touch-processing state may be set to one of a plurality of “states,” and the plurality of states may have rules for transitioning between the states. In various aspects, a host processor and a touchscreen controller may dynamically set, among other things, the scanning rate and resolution of a touchscreen panel based on the touch-processing state.

  • Publication number: 20140160086
    Abstract: Disclosed is a display device. The display device includes a timing controller temporally dividing one frame period and driving a display panel such that a display mode for displaying an image in the display panel and a touch mode for sensing a user's touch are alternately driven, and a touch sensing unit detecting the user's touch with a touch raw data difference between adjacent touch sensing blocks in the touch mode. In the display mode, the touch sensing unit generates a display compensation value for compensating for an error of the touch raw data due to a differential of display data applied to the adjacent touch sensing blocks to detect the user's touch.

  • Patent number: 8729411
    Abstract: When a user holds an optical scanning device to scan a micro dotmap on a displaying medium, a coordinate of a frame center of a retrieved frame on the displaying medium is calculated according to a decoding method for the micro dotmap in advance. A moving vector corresponding to a difference between difference frames scanned by the optical scanning device at different moments is calculated so that an instant location of the frame center on the displaying medium can be calculated anytime. Therefore, a large number of calculations brought by frequent decoding may be saved since merely a few calculations are required in calculating the moving vector. By further decoding the coordinate of the frame center at moments spaced with constant or variable intervals, errors brought by vibrations of the displaying medium are instantly fixed. Accumulated errors are avoided in the calculated instant locations of the frame center anytime.
