Definitions
- the present invention relates to a device for simplifying the use of a computer system.
- a computer system such as a microcomputer comprises a central microprocessor unit and a keyboard forming a control and data entry member.
- the object of the invention is to provide a device which, intended to simplify the use of a computer system by implementing a touch keyboard on the screen, is of simple design and allows the appearance of on-screen control windows superimposed on the current application, without modifying this application.
- the device which it relates to, by generating windows superimposed on the current application, intended for control by a touch screen covering the screen of the computer, is characterized in that '' it comprises at least a central microprocessor unit associated with its RAM and ROM memories, a window position RAM memory, a data RAM memory to be displayed in the windows, a keyboard interface intended to be connected to the keyboard connector of the computer, a peripheral circuit for managing the tactile keyboard and in that an electronic switching system allows it to be inserted between the screen connector of the computer and the screen itself so as to be able to select in real time the source of the data to display, keyboard or touch keyboard.
- This device allows a display window to be superimposed on the display screen of said computer system completely independently of the application in use, without having to modify or intervene in any way on system hardware computer or the application software running on said system.
- the window embedded by the device according to the invention can also be broken down into multi-windows, each corresponding to the display part of the device. This or these windows can, for example, be used for the simultaneous display of an application taking place parallel to the main application in progress on the computer system to which the device is connected.
- the overlay mode will always be graphic, i.e. the overlay does not depend on the display mode used by the system on which the device is connected (character mode or graphic mode).
- the device according to the invention therefore allows the sharing of a display screen of a computer system authorizing the running of two software applications generated by two independent electronic systems and displaying their results and / or their information on the same screen, without the main application being aware of this screen sharing.
- the device therefore makes it possible to superimpose, on a standard application, a parallel application making it possible to intervene on the main application while preserving the integrity of the latter.
- the device is able to simulate, towards the computer system on which it displays its windows, the entry of information as if it were entered on the keyboard of the computer system (simulation of input device).
- the device allows the addition of a simple input method, of the tactile keyboard type, covering the screen of the computer system and acting as a substitute for the mechanical keyboard and / or other input and / or pointing devices (mouse, ball of travel, etc.) usually connected to these computer systems.
- Computer systems always have screen, keyboard and data bus access in the form of connectors or not.
- the device according to the invention uses these accesses and no modification is necessary on the existing one.
- the device can be the subject of an independent box with its own power supply.
- the device can be inserted into an existing system (as a bus expansion card).
- the method can also be used during the design phase of a computer system of the host microcomputer type or the like.
- touch keyboard is considered here as an example of a possible device which can be effectively combined with the user-friendliness of applications, and that any other input device could be cited instead, such as a micro mouse. -informatics, a digitizing table, a displacement ball etc.
- Each of these peripherals can be taken into account by the device, the latter transforming the actions of all types of peripherals by pressing the keyboard towards the host microcomputer.
- the technique of the method therefore essentially consists in the description of the inlaying of the windows, the rest arising therefrom in the form of software for emulating a keyboard making it possible to transform the information coming from various peripheral tools into infor ⁇ the host computer simulating the physical presence of the keyboard.
- this device comprises a touch keyboard management unit, a keyboard interface to the host computer and that the central unit transforms the touch keyboard support information into standard keyboard data. to the computer.
- the microprocessor part is able to generate consecutive pre-programmed sequences of keyboard presses towards the computer.
- the touch keyboard covering the computer screen the central unit part is able to link the display windows of the device, pressing on the touch keyboard and the corresponding keyboard support sequences. dantes, generated to the computer.
- the invention will be clearly understood, with the aid of the description which follows, with reference to the appended schematic drawing representing, as a non-limiting example, an embodiment of this device:
- Figure 1 is a schematic view
- Figure 2 is a view of three screens, respectively, without inlay and with two types of window inlay
- Figure 3 is a schematic view of a screen without device and then with device according to the invention.
- FIG. 1 represents a device according to the invention in which the signals mainly used coming from the screen connector 102 of the computer are:
- - Data validation 9 validates the data present on the data bus 8 - Data bus: data to be displayed on the screen.
- Block 1 represents an electronic switch making it possible to select for display on the screen:
- This switch can be materialized in the form of standard buffers (type 244 for example).
- Block 2 represents the video RAM (memory) in which the data to be embedded is stored.
- Block 3 represents a RAM (memory) containing the image of the position of the window or windows to be superimposed on the screen, the corresponding data bits actuating the switching of block 1.
- Block 4 is a central unit based on a microprocessor associated with its working memories RAM and its strong memories ROM, and allows the management of the device and in particular: - the calculation of the address of the screen to which be displayed the current data on the data bus. This address is calculated from the frame sync and line synch information - The filling of memories 2 and 3 - The management 6 of the touch keyboard 101 - The management 5 of the keyboard connection 100 to the computer.
- An LCD screen can have various types of resolution, for example 640 dots in horizontal resolution and 200, 400, 480 dots in vertical (not exhaustive).
- the process works regardless of the screen resolution, the horizontal and vertical screen resolution settings being programmable in the process in manual or software form by the process microprocessor.
- a screen is also characterized by its "multiplexing rate": this parameter allows you to know how the screen will be refreshed: either in single screen, or in two half-screens.
- a final parameter is the width of the data bus of the screen: in general for screens of sufficient resolution (640 * 200), the data bus is 4 bits wide or 8 bits wide broken down into two 4-bit bits if the multiplexing rate is half the vertical resolution.
- the microprocessor will position its logic circuits according to the type of screen used. But whatever this type, the operating principle of the device will remain the same.
- a 640 * 400 resolution screen having a multiplexing rate of 1 / 400th (thus refreshing in a linear fashion) and having a data bus of 8 bits wide.
- the first value appearing on the data bus 8 and validated by the data validation signal 9 corresponds to the first eight pixels at the top left of the screen.
- the following values will therefore scan the entire screen, line by line.
- the device will be able to embed windows placed on the screen at a position multiple of eight pixels in the horizontal direction.
- the position resolution of the window (s) would be four pixels in the horizontal direction, the resolution of placement in vertical always remaining the pixel.
- the device waits for the synchronization signal generated by the frame synchronization signal, signifying the start of a complete refresh of the screen.
- This frame syncho top initializes a counter in block 4 whose purpose is to transform the number of "data validation" signals appearing from this frame synchronization top into a binary value.
- the binary value (fifteen bits for the current example) enters on the window RAM block 3 as well as on the data RAM block 2.
- RAM 2 and 3 will have been previously programmed by the device microprocessor as follows:
- the values of X for the current screen example with an eight-bit data bus, must therefore be multiples of 8, for 640 horizontal pixels, between 0 and 79.
- the values of Y are, for this screen, between 0 and 399 (400 pixels of vertical resolution).
- RAMs 2 and 3 are organized like the values of the data on the screen: for RAM 2, containing the values of the data to be displayed in overlay mode on the screen, these values are programmed in the RAM to addresses corresponding to the place where they must be displayed: the first value to be displayed being in position X1Y1 of the screen, the address at which this value will be found in RAM 2 will be: (X1 * 80) + Y1.
- the command 7 of the electronic switch 1 is done by the data contained at this same address in the RAM 2 (here for example, 1 to switch the block n ° 1 towards the data socket in the RAM 2).
- the RAM block 2 will be programmed as follows:
- RAM 3 will contain bits at 1 allowing switching by block n ° 1 between the screen and the contents of RAM 2 when these addresses are accessed by block 4, addresses created by the screen control signals and therefore corresponding to the position of the data on the screen being taken into account.
- the device according to the invention can be used with a PC type microcomputer (not limiting).
- the device according to the invention is connected to the microcomputer via the keyboard 100 and screen 102 connectors of said microcomputer.
- An analog tactile keyboard covering the screen of the microcomputer, is connected at 101 to the device.
- the device takes the information from the microcomputer keyboard and the tactile keyboard and transmits it back to the microcomputer as if only the keyboard of the host microcomputer was connected.
- the touch keyboard management unit 6 comprises a digital analog converter with two input channels allowing the conversion of the analog values on the x axis and on the y axis supplied by the tactile keyboard into numerical values usable by the central unit 4.
- the central unit deduces by simple calculation the position of the support in absolute coordinates.
- a correspondence table internal to the central unit then allows the software of the central unit to send the corresponding keypad codes to the computer.
- the device can:
- FIG. 3 shows schematically in D the traditional use of a computer system and in E the use of the same system with implementation of the device according to the invention.
- the device has a memory allowing it to record the associations "screen zones - touch screen zones - corresponding keys or key sequences.
- one or more of the windows generated by the device includes the design of the keyboard keys, the device then generating when pressing this or these "virtual keyboard” the same sequences as the keyboard of computer, which eliminates the need for an external mechanical keyboard.
