Claim:
1. A method of operating a touch-screen device, the method comprising: detecting, by one or more processors, a first moving touch on a touch-screen, wherein the touch-screen is able to detect a presence of the first moving touch but is not able to detect an amount of pressure being applied by the first moving touch; detecting, by one or more processors, a second moving touch on the touch-screen, the detected second moving touch occurring simultaneously with the first moving touch on the touch-screen, wherein the first moving touch is applied by a first finger of a user and the second moving touch is applied by a second finger of the user; detecting, by one or more processors, a line being drawn on the touch-screen by the first moving touch; calculating, by one or more processors, a calculated pressure for the first moving touch based on a distance on the touch-screen between the first moving touch and the second moving touch while the line is being drawn on the touch-screen by the first moving touch; adjusting, by one or more processors, a thickness of the line being drawn on the touch-screen by the calculated pressure for the first moving touch; displaying, by one or more processors, the line with an adjusted thickness on the touch-screen, wherein the adjusted thickness is based on the calculated pressure for the first moving touch; and further adjusting, by one or more processors, the adjusted thickness of the line being drawn on the touch-screen according to an additional pressure level determined by: where A is a predefined maximum number of fingers involved in drawing the line on the touch-screen, B is a quantity of fingers used to further adjust a thickness of the line drawn on the touch-screen, and C is a quantity of fingers used to draw the line on the touch-screen.
