FR2566326A1 - Device for the consistent redistribution of data processing keyboards - Google Patents

Abstract

The invention relates to a device capable of maximising the typing capability of the two index fingers. For this purpose, the number of rows is increased from 4 to 5, allowing the superimposition: group of 5 letters - finger column - colour. The essential logistic support is the "ESTA" order of decreasing frequency of the 26 letters and of their 5 groups of 5. The layout has been arranged in columns parallel with the "pyramid" in the centre of the figure containing numbers, mathematical signs and punctuation marks. Left index finger, Consonants, 52%. Right index finger, Vowels 41%. Total 93%. The device according to the invention is applicable to all keyboards.

Description

 The present invention relates to the organization of the canvas of mechanographic cellars.

 For a century, we kept to the QWERT "retarder keyboard", created in 1873 for this very purpose. It was a question of limiting as much as possible the congestion, réaetes, at the point of impact, which swallows for origin the fact that the instantaneous recoil of the hitting lever was not under control. When it was, the need for reformation was overshadowed by the "Methods", which in the meantime had been able to restore a certain balance, allowing speed to gain ground.

With the accelerated penetration of microcomputers, the same Methods can no longer meet demand, and, at school and even family level, a more suitable tool, would make even more followers @
With the "Clavier Marsan" (Cf: "Le Monde" 17.9.79) a first step was taken: asymmetry of the two hands, on the left the vowels, on the right the consonants (arrangement contrary to the "sense of writing") . The general plan in "bird wings" is similar to the Stenotypy (while the rectangular diagram keeps the possibilities of extension intact).

 The device according to the invention tends to promote a coherent canvas, easy to use, safe, fast, consequence of a rational, logical, functional, design (colors) redistribution.

 Assimilation is immediate, without any other preferential remedy.

 The whole @ of the restructuring was aimed at maximizing the "index positions", namely: two columns for each, on either side of the "pyramid", figure center.

Thus, the digital functional degradation (handicap of all keyboards), will be compensated by the magnitude of the typing capacity conferred on the same indexes: 93 93% of the "traffic", the "pyamide" in addition
FIG. 1 represents a configuration brought to 5 rows of all, arranged in columns, parallel to the "pyramid".

The consonants are on the left, the vowels on the right, because the keyboard must conform to the "sense of writing", which, eight times out of ten, involves consonant syllables - vowel, in order.

Figure 2 represents the rigorous integration of the "ESTA" Order
What? It was imperative that the distribution of the canvas (which should no longer be called into question), rests on an irrefutable logistical support, namely the decreasing periodicity rank of the 26 letters.

The combined standards, although imprecise so far, have the value of statistical data, for the percentage assigned to each letter, from a
text in French which has 2,080, with, in addition, 1,955 of its translation into English, for a total of 4,035 (more extensive criterion).

E.S.T.A. : these are the first 4 letters (40%) of the mixed sequence E.S.T.A.N.I.R.O.L.U. or 5 main vowels and S consonants (77%).

Average percentages range as follows * ESTANIROLU * * CRPDM * * FGBVN * * QXKJZ * * Y * 15 8.5 8.5 8 7.5 7 7 6.5 5 4 3 3 3 3 3 1 1 1 1 1 - 2.5 - 0.5
The alphabet is invariably divisible into 5 groups of 5 letters (+ Y) * EAIUO 40% ** STNRL 37% ** CHPDM 15% ** FGEVW 5% ** QXKJZ (Y) 3%
To have a consistent principle recognized, the number of rows. was raised from 4 to 5, so as to make all the elements coincide: *** group of 5 letters ** columns ** finger *** color = marker ***
Another derivative, the "Index cover" will have 4 key augments, that is 20 globally and 10 for each of them, for 2 allocated columns: a first, then a second position deviating from the "pyramid".

These privileged positions had to be occupied by the 10 priority letters "ESTANIROLU", as follows, in strict decreasing order: * 10 positidn left index: .5 main consonants STNRL = 37%, * l position right index : the .5 "true" vowels.. EAIOU = 40%,
*** Mnemotechnics: the 10 predominant letters gSTANIROLU = 77 Z.

* 20 position index left: the .5 secondary consonants CHPDM - 15 X, * 20 position index right: -Y- (consonant) -Q- (inseparable from U) = .1 X,
*** Total index capacity, exceptional, indiscountable = 93%.

*** Arrangement of the last two groups of consonants
* left = FGBVW (5%): major; XKJZ (2%): annular.

 Figure 1 also represents the organization of the "pyramid (which kept the alignment in rows, in order to break with the columns).

 Firstly, the numbers from # to 9 were introduced, as well as the mathematical signs directly associated, in a wider range.

 There was also room in the last row for the punctuation set.

 The canvas also shows other elements grouped together, the accents - all dissociated - located next to the vowels.

 With "all purpose" bars. the essential-of the keyboard confines to its claimed limits. It is advisable to leave to the local specificities, the latitude of the option according to the linguistic zone concerned.

 With this in mind, the proposed outline prefigures the "European Keyboard" with the peculiarities of its piilingilingualism.

 The device according to the invention is particularly intended to replace all existing keyboards. (Extension: useful toy).

Claims (6)

 1) Device likely to promote the "Ideal Keyboard" for use by the New Generation, which will thus have a logical, rational, functional, design tool, easy to use, fast, immediate.  The aim of all the restructuring was to maximize the "index positions", ie two columns for each, on either side of the "pyramid", in the center. Result: 93% of "traffic", the pyramid more  2) Device according to claim 1, characterized by a pasdé keyboard from 4 to 5 rows, scheduled in columns, parallel to the "pyramid".  3) Device according to claim 1, characterized by the positioning of consonants on the left hand and vowels on the right hand, in accordance with the "sense of writing", which interests 8 out of 10 syllables.  4) Device according to claim 1, characterized by the rigorous integration of the Order "E.S.T.A.. ', With indication of the decreasing percentages assigned both to the letters themselves and to their groups of 5. A consistent principle justifies the 5 rows: coincidence between *** group of 5 letters *** column *** finger *** color = marker ***  5) Device according to the invention characterized by the extent of the Index coverage, increased to 20 keys) or 10 for each of them, in two degraded positions away from the "pyramid". The first of the two, preferred, anticipates the 10 priority letters ESTANIROLU (77%). with, on the right the 5 vowels E.A.I.O.U. (40%), on the left the 5 main consonants S.T.N.R.L. (37 7), all in descending order provided.  As for the second position2, it received - on the left - the 5 secondary consonants C H P D M (15%), - on the right - Y and Q (1%), in all 16%.  *** Opportunities: H has been placed in the center of its "associates", for faster typing of the graphemes CH ... TH (English) ... PH, SH.  Consequently, the "index positions" bring together i7 + 16 = 93%! Same reflection for -Q-, inseparable from U. -Y- is vowel i consonant.  This same position is completed by all the accents, dissociated.  6) Device according to claim 1, characterized by the inclusions first of the last 2 groups of consonants2 FGBVW and XKJZ, respectively in left major and annular, then elements grouped in the "pyramid" (numbers, mathematical signs, punctuation), finally, the bars (for all uses complementary to those existing).  the proposed canvas, outside of its claimed standards, prefigures the "European Keyboard", with its own linguistic particularities.  ***, The claim has its limits: in fact, it cannot prevent, by option, the introduction of local specificities.
