    This claim claims the benefit of the US priority date Provisional Application 61/398, 892, filed July 6, 2010, the contents of which are hereby incorporated by reference. REVELATION FIELD
    This disclosure refers to monitors and, in particular, whiteboards. HISTORIC
    The digital whiteboard, sometimes called an interactive whiteboard, is a large computer screen or a projected image of it on which a teacher can simulate control of a mouse using finger gestures or by moving a special pen or any type of object over the projected image or on the screen. These images and screens generally have large dimensions. A typical digital whiteboard is approximately 1.2 meters high and 1.6 m wide, which results in a screen of approximately 80 inches. In some cases, whiteboards are even larger.
    Digital whiteboards are used in educational environments, where they replace blackboards with chalk and conventional whiteboards.
    One difficulty that arises with digital whiteboards is their limited size. Teachers generally require a minimum of a four meter long board for every half hour of teaching. During this teaching session, the teacher can fill an entire board with notes and observations.
    Conventional whiteboards are limited in size because most computer applications place toolbars on top of the monitor.
    Although accessible on a conventional computer screen, these tools are often beyond the reach of the teacher. As a result, digital whiteboards are often of limited height, typically less than 1.90 meters.
    To keep your margin within the typical range of a teacher, which is about 1.9 meters, a digital whiteboard with dimensions as specified above, would be placed 70 cm from the floor. This placement results in the following difficulties:
    First, most of the whiteboard will be so low that it cannot be seen throughout the classroom.
    Second, many teachers will be standing in front of the projector when writing, and this will cast a shadow. As a result, these teachers will not be able to view their own writing.
    Third, when the teacher turns to face the students, the brightness of the projector's light can be uncomfortable.
    Finally, most teachers find it comfortable to write on a limited part of the whiteboard, typically in a narrow 20-30 cm range at eye level. On a digital whiteboard with the dimensions specified above, the teacher would have only 0.5 square meters of whiteboard area that can be conveniently written. In most cases, this is not enough for a teacher to work.
    The previous difficulties disappear, to a certain extent, when the whiteboard is raised, as shown in FIG. 1. However, when the whiteboard is raised, the teacher cannot write easily about it in the higher course of the same. This difficulty can be avoided by providing several panels with bands that allow upward and downward movement of the panels. However, this option can be expensive and complicated. SUMMARY
    The present invention provides a digital whiteboard interface that allows a digital whiteboard to better simulate a regular whiteboard, but with the addition of a fully functional virtual personal computer interface. This virtual personal computer interface can be moved or resized just like any computer application on this virtual whiteboard.
    In addition, a mouse pointer, which functions as an absolute pointer position or a relative pointer position, can be used. Switching from one to the other can be done by clicking a mouse button, or a virtual button, for example, clicking an icon or gesturing in a specific way. The availability of a mouse is useful for large digital whiteboards where some icons are out of the teacher's reach.
    In one aspect, the present invention features a digital whiteboard system to allow the user to write in a preferred position. Such a system includes a digital whiteboard configured to cooperate with a computer, said digital digital whiteboard, in operation, being divided into a plurality of virtual panels; where the digital whiteboard locates tools and menu bar; where the digital whiteboard is configured to allow the user to move the virtual panel up and down by dragging a continuous scroll bar, and where the virtual panel moves in the same direction as the scroll bar is dragged.
    Realizations of the invention also include those in which the scroll bar divides the virtual panel into rectangles, those in which the scroll bar moves the virtual panel sideways, and those in which the digital whiteboard is configured to display a window in which it is a copy of a computer monitor.
    Among the realizations of the invention are those that also include a mouse that alternates between a working position as an absolute indicator and a working position as a similar relative position of the pointer.
    These and other characteristics of the invention will be evident from the description that follows and the attached figures, in which: BRIEF DESCRIPTION OF THE FIGURES

DETAILED DESCRIPTION
    The present invention includes a digital whiteboard that cooperates with a computer. The digital whiteboard locates tools and the menu bar within reach of the teacher's hands. These tools can be located at the bottom of the screen, or on its sides, or floating on the screen.
    Many conventional whiteboards have multiple panels that move up and down on tracks or tracks. The digital whiteboard described here emulates such whiteboards.
    The teacher can maintain a virtual whiteboard panel at a preferred time for writing by moving the virtual panel up or down. This can be done by dragging a continuous scroll bar that operates opposite to the way in which a scroll bar operates. In particular, the virtual panel moves in the same direction as the scroll bar is dragged, as shown in FIG. 2. The scroll bar itself can be moved to different locations on the whiteboard, so that the teacher can set the scroll bar in an ergonomically preferred position.
    Alternatively, or in addition to a vertical scroll bar, the digital whiteboard can also display a horizontal scroll bar. The horizontal scroll bar can help the teacher organize the board. Using appropriate pre-defined gestures, the teacher can place a scroll bar anywhere on the digital whiteboard. As a result, a teacher can move on a virtual panel in the same way that he moves on a panel on a real moving whiteboard.
    On a 2.4 x 1.6 meter digital whiteboard, scroll bars can divide a panel into 1.2 x 0.8 meter rectangles. By dragging the vertical scroll bars, the teacher can define the virtual panel at the best time. By dragging a horizontal scroll bar, if possible, the teacher can adjust the lateral position of the panel.
    In general, the top end of the digital whiteboard can be as high as 2.2 meters in height, or more, above the floor. As a result, it will be impossible for a teacher to operate most computer applications displayed in a conventional manner, such as an image projected on the whiteboard, as the menu that extends across the top of the whiteboard would be out of reach.
    To solve the above problem, you can provide a mouse that can switch between being an absolute pointer, such as a standard pointer on a digital whiteboard, and being a relative pointer, similar to a standard pointer on a computer. To switch between the two modes of operation, the user interface on the digital whiteboard provides an icon on the menu bar or toolbar or anywhere else on the digital whiteboard. If the teacher acts on this icon, the mouse changes from one mode to another. This switching function can also be implemented by a button on the pointer.
    When used as an absolute pointer, the teacher can, for example, easily write notes or control tools that are nearby. On the other hand, when used as a relative pointer, a teacher can reach, with the pointer, an icon that would normally be out of reach just by moving the mouse on a virtual mouse pad nearby, just as he would on a computer interface conventional. In any case, the status of the mouse down can be done by a gesture, for example, touching the digital whiteboard twice in the same place.
    Another way to provide the teacher with the necessary reach would be to provide an icon that, when pressed, causes a new window to appear. This new window shows a copy of the computer screen, without the whiteboard interface. The teacher can then access the virtual computer screen and all its functions. This includes moving the mouse pointer around this virtual screen and controlling the computer's functionality.
    The virtual screen of the previous computer can be moved by the digital whiteboard, as well as resized like other windows on the computer. Teachers can then play videos or show presentations on the digital whiteboard as they take notes near the virtual computer screen. For example, a teacher can copy a map from this virtual computer and paste it on the digital whiteboard, as shown in FIG. 5.
    On a dual screen, as shown in FIG. 6, a digital whiteboard application appears on a secondary screen and the virtual computer, which is a copy of the main screen with an invisible layer adjusted over it to control the position of the mouse, appears on the main screen. The digital whiteboard system allows the use of both previous solutions, so that the teacher can choose his favorite solution.
    As an example, the image (1) in FIG. 7 shows a proposed system for a 2.5 x 1.6 meter digital whiteboard. The scroll bar is located on a vertical line that divides the whiteboard into two 0.8 x 2.5 meter rectangular panels. A copy of the menu or toolbar is located on the right side, one on each rectangular panel.
    In the image (2) of FIG. 7, a virtual computer screen was added to the digital board. Images (3), (4) and (5) of FIG. 7 show how a panel can be moved up or down.
    FIG. 8 shows how a digital whiteboard can be mounted on a classroom wall. The outer frame is the border of the whiteboard. The internal structure is the limit of the image projected on the digital whiteboard. The height of this limit can be adjusted by changing the angle of the projector.
    In most cases, the main cost of a digital whiteboard system is the electronics implicit in the whiteboard itself. The cost of this framework is therefore proportional to its area. Using a system as described here provides a means of reducing this cost. In particular, since the teacher will not need to use the mouse pointer in the absolute position, nor will he be able to write across the board, and because more than one digital whiteboard is out of a teacher's reach, anyway , those areas out of reach of a whiteboard do not need to have any implied electronics. As a result, it becomes possible to produce a larger digital whiteboard without increasing its price.
    FIG. 9 shows how the digital whiteboard system described here reduces the area of shadow cast by a teacher on a digital whiteboard as a consequence of frontal projection.
    FIG. 10 presents a more detailed view of the digital whiteboard system that shows the menu and toolbar in more detail.
    The present invention can be implemented in other specific ways without departing from its spirit or essential characteristics. The described achievements should be considered in all aspects only as illustrative and not restrictive. The scope of the invention is therefore indicated by the appended claims and not by the preceding description. All changes that are generated within the meaning and scope of equivalence of the claims must be included within its scope.
