A method and system implementing menus for touch screens. A touch screen shows at least one menu that can be touched with a probe, which is the user's finger, for example. When the touch time of a menu reaches a predetermined time limit, a user is preferably given feedback indicating that the content of the menu will be varied. Feedback may be visual, audible, or haptic. There are basically two ways to vary the content of a menu. The menu can be enlarged from its default size, so that it contains a greater number of menu options. Alternatively, the content of the menu can be varied so that the size of the menu is constant but at least one of the menu options shown is replaced by another menu option. |
