At initializing the multi-line or calibration the single-line dynamic virtual keyboard is defined the individual user layout of the virtual keys of the basic line of dynamic virtual keyboard as reference points simultaneously by placing at least three fingers of left hand and/or right hand to pick up the touch screen in the individual lines. By releasing of all initialization fingers the dimensions of the keys, their topological location and slope of the vector model of the dynamic virtual keyboard are determined. Calibration of dynamic multi-line virtual keyboard constitute a keyboard layout model of of dynamic virtual keyboard where the fingers pull the touchpad sensing direction from the top down or from the center to the sides, or in opposite directions, whereby occurs calibration activation and by releasing the finger its ending. In doing so it leads to set the reference points and reference vectors, which represent key distribution of the top and bottom row of the kinds of dynamic virtual keyboard, followed by redefining the relative position vector of all other keys, according to the parameters obtained from calibration of the tensile reference vectors. |
