Definitions
- the present invention relates to cursor control devices used in conjunction with computers, and particularly personal computers.
- the invention relates in particular to a device with which any two-dimensional or three-dimensional object selected on the computer screen by pressing a function key without prior determination of a pivot point and without the aid of the keyboard, that is to say by the device's sole movement on a flat surface
- the pad can be rotated continuously in the X / Y plane of the screen and moved in a converging manner.
- software options can be executed by selecting appropriate graphical representations displayed on the screen of a monitor. Such graphical representations are usually referred to as "icons”.
- a specific software option stands for example for a task or a program that can be executed by the computer system. By selecting one or more software options, this can be done Operate the computer system in the desired way.
- a specific software option can now be selected by a line or area on the screen or the arrow shown in the arrow is moved so that it is on the corresponding icon.
- the selected software option is then executed by the computer system with an execution command.
- the user can move the cursor on the screen with the four “arrow” keys attached to conventional keyboards, that is, the cursor can be moved up or down with two keys and left or right with two keys.
- the execution command can be given with the "Enter” key.
- cursor control devices such as a mouse or a trackball have been developed.
- a typical computer mouse contains a freely rotatable ball that rotates when the mouse is moved over a surface, such as a desktop surface or a flat surface.
- the sphere is assigned transmission means or transducers which emit electrical signals which in turn control the position of the cursor on the screen.
- the ball and the transducers are usually located in a housing that has an opening from which the ball partially protrudes.
- the ball rolls on the base, which changes the signals emitted by the transmission means.
- These electrical signals are converted by the computer into a corresponding position of the cursor on the screen. So the cursor can be shown on the screen by a move the mouse accordingly on the surface.
- the button on the housing of the mouse the user can finally run a software option.
- a trackball has a construction similar to a mouse. However, the user does not move the housing, but rotates the ball, while the housing carrying the ball remains stationary, for example is attached to the computer housing.
- Devices of the aforementioned type also serve to generate graphic representations with the computer, to mark them on the screen, to change them and / or to move them within the X / Y plane of the screen.
- the rotary movements of the mouse ball are converted into electrical signals by the transducers mentioned, which the computer transforms into X / Y position coordinates for the cursor on the screen. Since the screen is two-dimensional and the predominant number of possible uses requires two dimensions, it is sufficient in many cases to be able to move the cursor as a point in the X / Y plane. With the known devices, however, difficulties arise when, within a two- or three-dimensional graphic, entire objects are not only to be shifted, but are also to be rotated in the X / Y plane at the same time.
- the object of the present invention is to develop a device for cursor control which overcomes the above-mentioned difficulties with a cost-effective construction and using known components.
- FIGS. 1 to 3 The structure and mode of operation of the device with its features characteristic of the invention are shown in FIGS. 1 to 3 and are explained below.
- FIG. 1 shows the schematic side view of a computer mouse 1 according to the invention
- FIG. 2 is a schematic view of the mouse underside and FIG. 3 shows a graphic representation of an image shift which can be carried out by means of the mouse according to the invention.
- the two conventional roller balls 4 and 5 are embedded in the underside 2 of the housing 3 at a distance d from the radius r and are held in such a way that they are set in rotation by moving the device on the flat base 6.
- the rotary movements mentioned are converted into electrical impulses by known transmission means, which are described in more detail below and which are not visible in the drawing.
- the latter are fed to the computer via the cable connection 7.
- Each trackball 4, 5 generates its own relative coordinates X 4 / Y 4 or X s / Y 5 , based on their local coordinate system.
- the numbers of the roller balls 4 and 5 are therefore used below as indices for the coordinates of the local coordinate systems.
- the value Y 4 of the front track ball 4 is selected to be identical to Y 5 of the rear track ball.
- the difference between the relative coordinates X 4 and X 5 of the front and rear trackball and the known distance d can therefore be used to determine the relative angle of rotation d ⁇ of the connecting straight line between the centers of the track balls 4, 5 , or their points of contact with the base 6 to calculate:
- the position of the trackball 4 is thus calculated, as in the conventional mice, from the relative X 4 and Y 4 coordinates.
- the device according to the invention is thus optimally compatible with the known computer mice.
- the conventional mouse function keys 8 are arranged on the top of the housing 3.
- the pressure or slide switch 9 on the side wall makes it possible to put the trackball 5 out of operation if necessary, so that the device according to the invention can then be used like a conventional mouse.
- switch 9 is only important if the software used does not automatically ignore the electrical signals emanating from the trackball 5 and transmitted to the computer.
- FIG. 2 shows a schematic representation of the underside of the device 2.
- the above-mentioned virtual straight line g runs through the center points (or points of contact with the flat base 6) of the roller balls 4 and 5.
- FIG. 3 shows a graphical problem on the screen of a computer, which consists in that the object 10 is to be seamlessly attached to the matching counterpart 11 simply by moving the mouse 1 according to the invention.
- the cursor corresponding to the trackball 4 represented by the star symbol (*)
- the computer places the virtual straight line g in the object 10 and thereby detects it as a whole.
- the line g as well as the cursor point representing the trackball 5, symbolized by a triangle ( ⁇ ), can be either visible or invisible to the user.
- the object 10 By intuitively moving the mouse 1 on the flat base 6, the object 10 can now be moved and rotated along the line 12 or along any other line until it is seamlessly attached to the matching counterpart 11.
- roller balls 4, 5 of the mouse 1 according to the invention preferably consist of the same material and have the same radii. Furthermore, the distance between the two roller balls 4, 5 preferably corresponds to at least four times the radius r of a ball.
- the transmission means of the aforementioned roller balls 4, 5 can include first and second transducers, with each ball 4, 5 being assigned two such transducers.
- the transducers are designed, for example, as rollers that are in frictional contact with the ball and have axes that are perpendicular to one another, as is already known in conventional computer mice.
- An advantage of the present invention is undoubtedly that the mouse 1 is compatible with all application programs hitherto on the market.
- the invention makes a significant contribution to greatly increasing the user-friendliness of existing and still to be expected applications, in particular drawing programs.
- the device according to the invention can not only have roller balls with associated transmission means, but also other displacement devices, for example those with two mutually associated wheels held at an angle.
