Abstract: A convenient method of inputting information into a palmtop computer device, a sticker keyboard and a computer device with this sticker keyboard are proposed, whereby the user may alternatively input information either by writing predetermined strokes like characters and numerals in a handwriting input area, or by acting (using predetermined handwriting actions) on smaller input areas arranged on the sticker keyboard, wherein the screen space available for displaying information is not reduced and the user does not have to swing from one area of the display screen/digitizer pad to another while inputting information.
