    摘要： Methods and apparatuses of obtaining user input. A display of an optical tracking grid (110, 804) is initiated (604, 702) on an electronic graphical display (104, 334, 802). Changes are determined (608, 714) among images of at least a portion of the optical tracking grid that are captured by a tracking pen device (120, 122, 318). Based on the determined changes in the images, a movement of a portion of the tracking pen device is determined (608, 716). A data set characterizing movement is produced in response to determining the movement (718).

    摘要： An efficient technique is provided for determining a portion of a document corresponding to a captured image. Areas of a document in which the pattern is at least partially obscured are identified. A reference pixel in the image is selected, and an offset between the pixel and the pattern is determined. A pixel-by-pixel comparison is then made of the image with the document such that the reference pixel is only compared with locations in the document that are both within the identified areas and have the determined offset from the pattern. The comparison with the highest correspondence between the image pixels and the electronic document then identifies the position of the reference pixel relative to the electronic document.

    摘要： A display apparatus includes a plurality of color filters corresponding to subpixels forming pixels of the display apparatus, and a black matrix formed among the plurality of color filters, and the plurality of color filters includes a pattern indicating an absolute location of each pixel of the display apparatus. A pattern indicating a location of a pixel may be formed in subpixels of a display apparatus and inputting may be performed and thus, a display panel may not affect a thickness as opposed to a digital paper, luminance and a contrast ratio of a display screen may be secured, and location information of the pixel may be intensively represented. Accordingly, the display apparatus may be applicable to a display apparatus having a huge size and a high resolution.

    摘要： Disclosed are an optical film and an electronic pen system. The electronic pen system includes: a reflective display configured to display information by using surrounding light; an optical film disposed on the reflective display, and formed with an information pattern including virtual grid lines and a plurality of marks for providing position information by using light reflected from the reflective display; and an electronic pen configured to recognize the information pattern, and transmit a signal for displaying graphic information on the reflective display.
