Definitions
- the keyboard mentioned is limited to four operating states.
- only 256 different signals can be transmitted with an 8-bit code and an additional bit for parity control.
- Keyboards for transmitting signals of all kinds can be used in many different ways. It is an object of the present invention to present an input device which can be used in an extended range of applications without the fast, perfect, blind, rhythmic operation of the keyboard being significantly disturbed with ten fingers.
- the solution to the task presented here is based on the fact that working on display devices and other locations for keyboards can be concentrated in individual work sessions.
- Keyboards can be used for very different purposes, for example to write business letters, enter computer programs in different programming languages, create computer graphics works of art, write poems, bilingual texts or, scientific texts (language science, mathematics, physics, chemistry ect. ) to write, to operate robot control systems, machine tools to control entire industrial plants and the like.
- a working day of a business scientist on a screen device could therefore begin with a work session in which he types in several business letters, followed by a work session in which he enters a computer program for controlling a scientific instrument and can see it end with a working session in which he works on a scientific text for his clientele.
- the assignment of key functions can be optimized differently.
- the digits usually play a subordinate role when editing a linguistic text, while they become much more important in programming replacements or when writing certain business letters. It should therefore be aimed at in the 2 additional new operating states of the keyboard made accessible by the second shift key 41 again and again to make new, cheap groupings of key functions, partly in repetitions of certain functions in a geometrically advantageous position, differently accessible again and again to be able to optimally support certain types of work tasks on the screen.
- the input device should be portable and can be connected anywhere in order to enable it to be used in various work sessions that are spatially far apart (example: repair service from a computer specialist).
- Input devices should be personal property in order to enable an optimal configuration for each individual.
- the input device can only be transported and meaningfully connected to different devices if the signal code is unique and self-identifying, so that the conventional consideration of the spatial design of the key assignments when interpreting the code signals by the computer can be completely dispensed with.
- An 8-bit bus (plus 1 bit parity control) is therefore not sufficient here and an expansion to a larger bus width is necessary.
- the object of this invention is to provide an input device for a data processing system in which the keyboard can be preconfigured in a simple manner by the user before starting work, in order to operate the keyboard undisturbed, quickly, completely, blindly, rhythmically at ten Enable fingers during a work session in an optimized way; this is to be done by preselecting the assignment of key functions for each individual key that are contained in the two key fields, by making the individual keys connectable to several different groups of coding units.
- a simply designed work station which is suitable for accomplishing the task of this invention can comprise a personal computer with screen, central unit, two keypads and, for example, a wall-mounted switch board, as shown in FIGS. 15 and 16.
- Switchboards are added to the left and right keypads and can be installed in a common housing with the keypads. Such a structure is shown in supervision for the left hand in Figure 1 and for the right hand in Figure 2.
- the device shown in top view in FIG. 1 is referred to below as the left sub-device; the device shown in top view in FIG. 2 is referred to below as the right sub-device. Together, the left and right sub-devices form the input device, according to claim 1. Should the left and right keypads be mentioned together below, they are referred to as the keyboard, which represents part of the input device.
- the terms signal lines and signal lines are used synonymously and mean metallized lines or lines on an electronic circuit board (electronic card) which can carry electronic circuits and circuits and not only on at least one front and one rear side but also in intermediate layers ( Sandwich) can carry metallized lines or lines, so when crossing bundles of several Signal lines can be dispensed with if possible. However, individual bridges are possible, as at the position indicated by B1 in FIG. 17, where two 9-bit buses cross.
- Si gna l lines (630-632) in Fig. 17 connect the two sub-devices, so that a signal from one of the switch boards can change a configuration in both sub-devices at the same time; in another version of the inventions, the signal lines (630-632) are separated, however, so that the configuration can be carried out separately in each subunit.
- the input device is powered by the central processing unit of the computer (46008). In contrast, in a preferred embodiment of the invention, the input device will have its own network connection.
- Fig. 16 shows for execution forms of the invention, in which many electronic circuit boards are used, an additional box (46016) of the input device, which can accommodate these circuit boards.
- the additional box has its own connection cable (46023) to a socket (46017) of the public network.
- the additional box contains the conventional means for voltage conversion, which provide at least + 5V-, + 12V, + 24V for the power supply of the boards also to the sub-devices should.
- a power supply for the input device that is independent of the computer to be connected also has the significant advantage that the input device can be transported to various computer systems, even if its electronic components require unusual power supplies.
- the partial keyboard of FIG. 1 shows a control key (410), the function of which is either that of a repeat key or that of a second shift key in addition to key 41.
- the electronic circuits for supporting the control key and the other keys on the keyboard are shown in FIGS.
- FIGS. 11 and 12 See, which also show that both sub-units contain a first (83) and second (84) switching device, which are identical to the first and second switching device of Fig. 5, wherein the electronic switching device for switching device (83) in Fig. 7 and the switching device switching circuit (84) is shown in FIG. 8. The following can be seen in FIGS. 11 and 12:
- Power supply cables (20120, 20124) to ground; Cables (20123, 20127) to + 5V; Lines (20121, 20125); to a conventional electronic clock for generating a square wave adjustable frequency; Cables (20122, 20126) to + 12V or + 24V to support special units such as Schmitt triggers, monostables Mu lt ii brators and the like for generating a special + 5V pulse of higher power, with the advantage that such special units and connected widened signal lines for key actuation signals need only be assigned to individual keys.
- special units such as Schmitt triggers, monostables Mu lt ii brators and the like for generating a special + 5V pulse of higher power
- Schmitt trigger monostable le Mu lt i vi bratoren or similar pulse-forming units of lower or increased output are lei stung in means (2000) whose Heidelbergbi ld in an Au 's enclosuresform for low power in Figure 13 is shown. (2086) is a derivative.
- buttons can be used in the present keyboard. Peculiarities of the shape of the button head are irrelevant for a blind user. However, if the quality of the conventional keys is different, it is important to ensure that the key mechanism does not affect the speed of the finger movement.
- the feedback device for the key head which usually comprises one or more mechanical springs or spring systems, can withstand the repetition speed of a master's fingers.
- Each two-stage button is connected to a double switch; the button is depressed in a first step to a first mechanical resistance level, so a first electrical contact is closed in the double switch; if the button is pressed even further down to a second mechanical resistance level, a second electrical contact in the double switch is closed and the first contact is opened.
- FIG. 14 The electronic circuit diagram for double switches (2001) of FIGS. 11 and 12 is shown in FIG. 14; (20109, 20110) are bleeder resistors, which have similar tasks as (2086) in Fig. 13.
- Two level keys have the advantage over single level keys that they make a repeat key superfluous. Therefore, each double Ischa tter must also be connected to a signal line that can deliver a periodic square wave signal.
- Simple switches (2002, 2003) are shown for individual buttons; The switch (2002) does not need to be coupled to a device (2000); The switch (2003) must be coupled to a device (2000).
- FIG. 11 shows that the control key can take over the function of a second shift key, so that together with the key (41) a second shift key can be operated from both sub keyboards.
- the output signal lines of the switch device (84) from both keypads can be coupled so that both second switch buttons are effective in both sub-devices (the first switch buttons must be effective in both sub-devices); however, the effectiveness of the two second switch buttons can be separate for both sub-devices; for this case, separate signal lines (94100, 94101) are shown in FIGS. 21A, 21B for the right-hand subunit.
- connections (22102-22105) can be connected to the connections (21102-21105) on the back of an electronic card; also (22167-22169, 22410) with (21167-2169, 21410).
- connections (2101-2111) are individually assigned to the corresponding buttons (1-11); the following assignments also apply: (2113-2117) to (13-17), (2119-2124) to (13-17); in the right keypad (2125-2140) to (25-40), (2142-2148) to (42-48), (2150) to (50), (21411-21 12) to (411-412). All connections together or groups of connections can be connected to a single connector or several plug connections can be combined so that bundles of signal lines for key actuation signals in cables combined in a partial device can be routed from a first electronic card, which carries the parts described for FIGS. 11 and 12, to a second electronic card.
- the signal lines are combined on the second electronic card and on a number of further electronic cards, which are connected one behind the other by means of cables and plugs, to form a bus.
- this bus is common to both keypads, shown in simplified form as four lines which emanate from four key switches (60-63). 17-20, the bus is also shown in simplified form by means of four lines.
- FIGS. 21A, 21B show the left version of this bus for key actuation signals, and FIGS.
- FIG. 17 shows a simplified Circuit which is present exactly once in each sub-t, whereby only one configuration device (4570) is present in each sub-device, the electronic circuit diagram of which is shown in FIG. 28.
- the configuration device comprises at least three bistable pins or flip-flops (615-617) (one pin for each configuration of the keyboard), diodes (633-638), and AND gates (618-621, 6181, 6201, 6211) .
- the symbolic connections (6110-6113, 6171) indicate that the configuration unit can be expanded if more pins, diodes and AND gates are added.
- the connections (630-632) from both subunits are connected via a cable, so that the entire keyboard can be configured together from just one switchboard (4601) in one subunit, or from two switchboards that are distributed across both subunits .
- the separation of the cable connections (630-632) enables the two sub-units to be configured separately, whereby the alphabet must be repeated.
- the electronic circuit for the coding units (70-73) is shown in FIG. 9.
- the units (4710) comprise conventional means for Independent storage of 9-bit signals and for re-reading the stored signal as long as button (410) is depressed.
- the presence of two data busses (74-82) and (74A-82A) has certain advantages for the connected computer in that a partial IDecoding of the code signals is made possible by the division of the bus in advance.
- code signals for an alphabet and the digits 0-9 appear on bus 74-82, while on the second bus more heterogeneous code signals, for example for computer controls and rare characters, also appear a repetition of the digits 0-9 if this is the working session favored by an individual.
- the bus control units (4710) can additionally have conventional 9-bit gates, which can receive an ' open signal ' through a selector switch (not shown) in the bus control unit, so that both buses can be connected to one another. Furthermore, both bus control units (4710) can still have conventional means for sequencing the 9-bit code signals.
- FIG. 17 shows an electronic circuit for an expanded version of this invention. While in FIG. 17 the key combinations are always changed over to coding units in every reconfiguration process for all operating states of the second switching device (84), it is also possible according to FIG. 18 to ensure that only individual parts of the keyboard have a certain reconfiguration echani smus are subordinate.
- FIG. 18 shows an electronic circuit for an expanded version of this invention. While in FIG. 17 the key combinations are always changed over to coding units in every reconfiguration process for all operating states of the second switching device (84), it is also possible according to FIG. 18 to ensure that only individual parts of the keyboard have a certain reconfiguration echani smus are subordinate.
- switch boards (4601), (4602) and (4603) are therefore shown as subunits, from which the user can reconfigure individual parts of the keyboard. These switch boards are each coupled to a configuration device (457). The circuit for the configurator shown in Fig. 26.
- the number of coding units that can be coupled in an operating state of the configuration devices depends on the internal structure of the configuration devices; Devices (4570) can each make 4 coding units couplable at the same time, while devices (457) can only make two coding units coupled together. Those coding units that are made couplable at a certain moment in accordance with the set operating state of the configuration devices are referred to as the configured set of coding units.
- Only one of the coding units of the configured set is kept open for signals on the bus for key actuation signals by the second switching device (84), depending on the operating state of the second switching device, depending on which switching buttons (12 ), (18), (410), (41), (49) if the configured set comprises 4 units. However, if the configured set only comprises two units, then a coding unit of the set is only kept open in two operating states of the second switching device.
- the control board (4602) in FIG. 18 includes a group of coding units which can predominantly generate code signals for various alphabets (Latin, Cyrillic, Arabic, etc.).
- the configured sentence of the group contains two units and is able to generate code signals for a complete alphabet, whereby one unit for the large and the other unit for the small letters generates the code signals (in alphabets with large and small letters).
- Switchboard (4602) configures a group of coding units that correspond to the keys (1-11), (13-17), (19-24), (25-29), (31-35), (37-40) , (43-47) and (50) can be coupled (according to sub-claim 4.)
