ABSTRACT:
This invention relates to a digitizer system including a pointer (e.g. stylus, puck, or the like) for movement over or along a corresponding tablet. More particularly, the system functions to change the pointer's cursor shape being portrayed on a corresponding display screen as a function of the position of the pointer within the menu area of the tablet. This application also relates to a digitizer tablet including physical or mechanical structure (e.g. bump(s), aperture(s), step(s), etc.) proximate the work surface of the tablet for indicating to the user the presence or location of the menu area.
BACKGROUND OF THE INVENTION
For many years digitizing, writing, or graphics tablets have incorporated menu strips. These are usually a series of square or rectangular blocks along the top edge of the drawing area. Clicking on one of the blocks in the menu strip with the pointing device executes a command or changes a tablet operating parameter. The problem is that the operator has to look away from the screen to the tablet in order to locate the desired menu area or subitem block. This is undesirable.
It is apparent from the above that there exists a need in the art for a digitizer system wherein the user is efficiently informed or made aware of the location of the pointer (e.g. stylus, mouse, or puck) within a menu area of the tablet, so that the user knows in which portion of the menu area the pointer is located without having to look downward from the screen toward the tablet. There is also a need in the art for a digitizer system wherein the user can feel the presence of the menu area of the tablet without having to look down at the tablet during drawing/writing operations.
It is a purpose of this invention to fulfill the above-described needs, as well as other needs in the art which will become more apparent to the skilled artisan once given the following disclosure.
SUMMARY OF THE INVENTION
Generally speaking, this invention fulfills the above-described needs in the art by providing a digitizer system comprising:
a digitizer tablet having a menu area and a plurality of different menu items therein;
a pointer (e.g. stylus or puck) for movement over the tablet and over the menu area; and
means for providing an on-screen cue on a corresponding display which indicates to a user which menu item in the menu area the pointer is proximate.
This invention further fulfills the above-described needs in the art by providing a method of changing a shape of a cursor being portrayed on a display screen as a function of a position of a pointer within a menu area of a digitizer tablet, the method comprising the steps of:
providing a digitizer tablet having a menu area with a plurality of menu items therein for selection;
providing the pointer for movement over the tablet and for selection of menu items;
providing a display which is in communication with the tablet, wherein a cursor shape is portrayed on the display in a location determined by the position of the pointer on the tablet; and
adjusting the cursor shape being portrayed on the display when the pointer is moved in the menu area from one menu item to another menu item so that the user can determine which menu item the pointer is over without having to look at the tablet.
This invention further fulfills the above described needs in the art by providing a digitizer tablet system wherein the tablet includes physical structure on or proximate the tablet surface in a menu area thereof, so that the user can physically feel (either directly, or indirectly through a pointer) the presence or location of the menu area without having to look down at the tablet.
This invention will now be described with respect to certain embodiments thereof, along with reference to the accompanying illustrations wherein:
