Claim Text:
1. A method of operating a touch-screen device, the method comprising: detecting, by one or more processors, a first touch at a location on a touch-screen, wherein the touch-screen is able to detect a presence of the first touch but is not able to detect an amount of pressure being applied by the first touch; detecting, by one or more processors, a second touch on the touch-screen, the detected second touch occurring simultaneously with the first touch on the touch-screen, wherein the first touch is performed by a first hand of a user touching the touch-screen, wherein the second touch is performed by a second hand of the user touching the touch-screen, wherein the first hand of the user draws a line on the touch-screen, wherein the second hand of the user controls a thickness of the line drawn on the touch-screen by the first hand; calculating, by one or more processors, a calculated pressure for the first touch based, at least in part, on a value corresponding to a feature of the detected second touch; adjusting, by one or more processors, the thickness of the line drawn on the touch-screen according to the pressure level determined by: where A is a chosen maximum number of fingers involved on either the first hand or the second hand in drawing a line on the touch-screen, B is a quantity of fingers from the second hand used to adjust a thickness of the line drawn on the touch-screen, and C is a quantity of fingers from the first hand used to draw a line on the touch-screen; and generating, by one or more processors, a touch-screen output according to the location of and calculated pressure for the detected first touch.
