Definitions

  • the present invention relates to a method for inputting data via a keyboard, the keys of which are assigned to individual characters of a character set, the number of keys being smaller than the number of characters of the character set, and wherein the character set preferably contains punctuation marks.
  • the mechanical writing has the advantage compared to the handwriting that it is less tiring and the written text can be easily supplemented, corrected, stored, as well as electronically, visually, audibly and tactilely spent and received recognizable.
  • the input is particularly efficient when used with the "blind stop", i. without eye contact with the keys, takes place. Many people make use of machine writing using the PC, but there are many more people who can only partially or not use it. Apart from the fact that the PC has not yet reached the threshold of reduction to an efficient "pocket-size" device, which can be used by anyone on a mobile basis, even though the technical prerequisites exist.
  • sequences of key presses which correspond to sequences of characters that are impossible or unlikely in the context of the data to be entered are used to encode characters or character strings that are not assigned to a key.
  • characters or character strings that are not assigned to a key.
  • character combinations such as ", a”, “, b”, etc. (usually followed by a space after a comma, "qa”, “qb”, etc.) do not occur.
  • the invention also relates to a method for outputting data via a display, an expression or via volatile stimuli, by symbols associated with individual characters of a character set, the number of symbols being smaller than the number of characters of the character set and wherein the character set preferably contains punctuation marks.
  • Volatile stimuli in the above sense refers to a type of output in which pressure or other tactile detectable stimuli are applied to areas of skin of the user in chronological order to represent characters, thus not requiring the user to actively pick up a reading zone.
  • sequences of symbols which correspond to sequences of characters which are impossible or unlikely in the context of the data to be entered are used for coding characters or character strings which are not associated with a symbol.
  • Output symbols meant in this context are characters, for example in the manner of Braille characters. Even ordinary six-point Braille, which allows only a limited set of characters, is difficult to learn for many people, such as the blind. This is even more true for the extended Braille with eight points.
  • the basic idea of the invention It is now applied to the output by limiting the number of symbols used. This may mean that the concept of a 6-point Braille font is retained, but easily forgettable symbols are omitted. However, this can also mean that one type of 4-point Braille is used with a correspondingly reduced supply of symbols. In the same way as typing a larger font onto a small number of keys, the font is now mapped to a small number of symbols in the output.
  • the invention relates to a method for outputting data in the manner described above, in which characters are represented by stimulating different areas of the skin of the user and in which each skin area are assigned a plurality of excitation modes, which are used alternately.
  • the excitation mode is changed over time, for example by spatially dividing the skin area into subregions or excitation points for a specific point. By regular or stochastically controlled variation of the mentioned excitation points a fatigue can be prevented. As a rule, all information points and thus all excitation modes are synonymous with the information content.
  • such an output may be performed, for example, as follows.
  • the five fingers of a user's hand are inserted into corresponding receiving openings, so that the fingertips opposite excitation devices, each consisting of ten extendable needles.
  • the execution of a needle perceived by the respective fingertip corresponds to the output of a point in a 5-point code, with the 32 Characters can be displayed directly.
  • the needles 1 and 8 are activated in the corresponding receiving opening.
  • the needles 2, 3 and 10 are addressed, which corresponds to an alternative excitation mode.
  • this stimulus differs in strength and location from previous ones, which counteracts fatigue.
  • distinctions may be made in the oscillation frequency or the like.
  • the different excitation modes described above are always synonymous.
  • the user may be given an indication by the excitation mode as to whether a particular character combination is a code for a single character or a shorthand code for representing an entire word or portion of text.
  • the typewriter keyboard (PC keyboard, full keyboard, QW E RTZ-Ta stature) makes all characters of the common character set of the respective language ready to be displayed. The entry is made in a single or changeover stop. The characters can be written on the keyboard with both hands and without eye contact with the keys (blind). However, these "blinds" are often not mastered, so write efficiency is low on average.
  • the keyboard forms with the computer, monitor and printer a unit that secures the Internet access and can be networked with other units.
  • the PC keyboard is also used in laptops, as well as in small versions, where the blind stop is not possible because of the small size of the keys. Speech impaired mobile communication devices with voice output, LCD display and strip printers are offered, whose keys are arranged in alphabetical order.
  • E2 VIRTUAL KEYBOARD BENCHES (Fig. 2C):
  • the bottom of the [B b ] control panel contains the virtual keyboard levels [B vl ] [B v2 ] [B v3 ] [B v4 ]. They support their virtual levels. If they are not needed for this, they are also available to the operating block [B b ].
  • Mentally below the primary character block [P b ] is the capital letter block [G b ], the calculation block [R b ], function block [F b ], cursor block [C b ] and any other.
  • the characters on the blocks may be called "flying" (see alternative stops), temporarily or permanently on the upper keyboard level, such as the capitalized capital block [G b ] for continuous capitalization or the computational block [R b ] for performing arithmetic operations ,
  • the substitute input can be written in a variety of ways, with reference to destination input, to make it as easy as possible for users to access text input.
  • the replacement input for the [?] E.g. be the word [question mark] or a mnemonic cutback such as [question, frz, or fr].
  • a secondary character is required for a replacement input, such as a [ü] for [five]
  • the replacement input can also be written incorrectly, such as [five] or as [finf].
  • the variants defined a priori with which the replacement entries are "allowed" are stored with their common destination input in a large file. If a written variant matches a defined variant, the destination input will be entered in the respective input file.
  • the specified variants of the replacement input must be unique, which requires a corresponding labeling. The distinguishing marks between natural and artificial.
  • B2 ARTIFICIAL CHARACTERS, hereafter referred to as [eee], are set by the users during the writing process.
  • the marks [ k ] can be an integral part of the substitute entry [ k eee, eee k , e k ee] or stand alone [ k _eee].
  • a substitute entry may have one or more identifiers of the same or different type [ k ee k e] [ k2kl eee].
  • the labels may be lower case [ b ], numeric codes [ ⁇ c ], alphanumeric codes [ ac ], as well as punctuation and special characters [ s ]. Markings also occur through stops on non-character keys [ t ⁇ ].
  • B3: COMMON LETTERS are only qualifiers if they are presented as they would normally never be encountered, for example as [c, j, w] at the end of a word or as [ßfß, czz].
  • RARELY LETTERS such as [q, x, y] are very useful as labels. Especially if the license plate is unmistakable.
  • SYMBOLS The comma are used as marks in those places where they are not normally used, such as [_, eee] [e, ee] [eee, z]. Other punctuation marks are very good if they are rare.
  • acoustic and textual editing functions are provided, which can also complement each other.
  • the other editing functions such as search, copy, cut, paste (and the like), the functions of the toolbar (PC) and the parameter settings of the icon of the screen (PC) with input of the word of the function, with mnemoischen word cutbacks of the same or coded (acoustically or textually) "directly" be called.
  • the real upper keyboard level [RO] of the one-hand keyboard consists of the primary character block [P b ] (BO to C3), which consists of the 10 character keys and the operator block [B b ] with the keys Fig. 1 and Fig. 2.
  • Primary characters (as stated) can also be used for the operating keys and for carrying out operating functions also the primary characters.
  • Other blocks Function Block [F b], the cursor block [F b] and any further.
  • (C) DREIFINGER KEYBOARD The keyboard of Fig. 4A has three horizontally arranged keys which are struck with the three middle fingers of one hand. With a stop 7 (without zero stop) with two stops 49 different signs can be entered.
  • FIG. 4B The keyboard of Fig. 4B has three triangularly arranged keys on which 49 characters (as in Bl) can be inputted with double strokes of the thumb.
  • BRAILLE Named after its inventor Louis Braille (1809-1852, Frenchman, blind) font is the only Braille used worldwide. It shows the characters with semicircular raised dots on paper or other transparencies, on a matrix of 6 or 8 dots, so that they can be perceived as they pass over the tip of the reading finger ( Figure 5C).
  • the matrix of the 6-point Braille consists of 2 columns and 3 rows, on which 64 different characters (63 without zeros) can be represented with single points or point combinations.
  • the dot combinations [p3 + p6] are used as an announcement character.
  • Braille is used in German as a full font, shorthand, stenography and computer braille. Braille is displayed permanently and temporarily, as well as expired. Permanent Braille is printed with recorders and printers on special 160g paper: Patrices press the raised dots into the underside of the paper, making them hemispherical on the surface of matrices. Modern printers duck the majesty on both sides.
  • a Braille module (FIG. 5A) is provided in a matrix-compatible manner. By juxtaposing modules, the braille lines (Fig. 5B) are formed. Longer lines have 80 modules, average about 40 and small 20 modules and less. The modules have at the interfaces of the trix round openings in which round-headed pegs (pins) with a hemispherical tip are raised with piezoelectric elements to represent the characters and lowered after the reading operation (FIG. 5C). After reading one line, the next is called by pressing a key on the line.
  • Volatile Braille is emitted in communication with deafblind, see point (C) below. 92% to 93% of the blind have no access to the Braille. This is because the knowledge of tactile typing and the PC, which are taught to the blind at a young age, in most cases can no longer be taught to the late blind, who make up the majority of the blind. Especially not if they do not have sufficient knowledge of machine writing.
  • Deafblinds are also users of Braille, although in this document they also communicate hand-to-hand with others. In doing so, the transmitter uses his fingers to press the Braille characters onto the fingers of the receiver, as if his fingers were a 6-point Braille keyboard. The printing is repeated several times (tumbled) so that the character can be unambiguously received. In some countries, the forms invented by Hieronymus Lorm (1821-1902) are also used to communicate with deafblind people. With this, the transmitter writes the signs with a finger of his hand in the hand of the receiver. Similar fugitives exist in other countries as well.
  • EFFICIENT WRITING INSTRUMENTS For entering text, blind electronic devices are also available, as well as comprehensive workstation equipment with PC or laptop, voice output, Braille display, Braille printer and other hardware and software. These devices have a full keyboard, whereby the written in normal writing can be converted into Braille. Efficient inputs are also provided by the Braille-Organizers and Braille-NoteBooks with similar features, but Braille keyboard (Fig. IA and Fig. IB). These devices usually can not be used by the later blind.
  • the keyboard has the capacity of a small computer (organizer), with which also the multimedia connection can be made.
  • the text written in plain text can be converted into tactile text, as with the PC.
  • a supplemental insert speech output text-to-speech
  • a tactile display for strongly visually impaired a display intended for large font representation.
  • TACTILE PRINTS The simple Braille writers are also printers. When the keys are touched, the patterns stored on racks are pressed against the inserted paper. As the pressure continues, the paper presses the paper into the die, where the raised points are hemispherically shaped.
  • the actual Braille printers are stand-alone devices, which are available in different versions. All modern printers can print texts on two sides, some of them also tactile graphics. The largest of them are run by blind institutions. They are predominantly used to print books. Moon does not have its own printers, but the moon marks in dotted lines can also be printed using Braille printers.
  • Bl CONVENTIONAL BRAILLE ROWS (Fig. 5B): Efficient writing without the use of a braille line is unthinkable today, since the speech output is not sufficient even for qualified scribes to produce texts in appropriate quality.
  • Braille lines are used in the PC as a full line with 80 modules or as a half line with 40 modules, in LapTops mostly with 40 modules, as well as Braille notebooks and Braille Organizers with 20 and fewer modules. Braille lines have opened the blind to the Internet and thus to the information society, greatly reducing the need for Braille printouts. Their importance is therefore not high enough to evaluate.
  • B2 NEW ENDLESS BRAILLE DISPLAY ( Figure 6): In a novel endless display, the Braille modules are located on a covered rotating disc. As you rotate the disc, the characters are moved to the display area for reading with your finger. The function keys are also used to set the rotation speed.
  • the advantage of the display is that it can display an unlimited amount of text and that the reading finger does not have to cover wide reading distances, but can remain stationary. It is, in principle, an ideal reading device in which the texts are transiently output. It is thus in competition with the Braille expression.
  • deafblinds also communicate with each other hand-to-hand, using their fingers to press (drumming) the Braille characters onto the recipient's fingers as if they were whose fingers are a 6-point Braille keyboard.
  • This principle of "volatile" output of Braille is also applied to a deaf-blind communication device. It has a 6-point Braille keyboard on which the characters are written and transmitted to the user electronically. Underneath the buttons are 6 troughs with vibrating buttons. In these the scribe intervenes with his fingers to receive the response to his message (in Braille).
  • Example 1 Stored Text: [If I had a computer, I could write 1000 poems!]; Retranslation: [If I had a ccomputer, I could write ajjj gge Why call sign].
  • Example 2 Stored Text: [I nonetheless believe that the train will come today]; Retranslation [i believe that it will come today].
  • a primary character set of 24 tactile characters can save 62% of all 6-dot Braille characters, which makes it easier to learn and recognize the characters, because the 24 characters have fewer dots and a smaller matrix than the 6-dot Braille can be represented.
  • A4 PUNK REGISTER WITH 4- PU N KT MATRIX (Fig. HD): This version has a perfect matrix with two columns and two rows. On it 16 point combinations can be displayed easily readable. It is suitable for displaying alphabetic, numeric and alphanumeric codes. A primary character set of so few characters is possible in principle if use is made of several announcement marks (see point 4.1). (6) NEW TACTICAL EXPENSES
  • Braille reading is an active process that places intellectual and physical demands on users. Reading on the endless display, however, makes the physical effort easier, as the finger remains stationary while reading.
  • the volatile Braille output on the deafblind communication device (see point 4.3C) makes use of the braille but does not show any possibilities for extending the principle. Our invention deals with it.
  • (C) IRONING CONCEPT Our visionary output of volatile tactile information provides stimulus modules comparable to Braille display modules. On these are one or more stimuli that move the stimuli.
  • the stimulus bodies are comparable to the plungers (pins) in the Braille display.
  • Our stimuli can also be pins, bolts, wheels, pliers and any other objects.
  • the stimuli exert the stimuli with pressure, vibration, friction, impact, scratch or any other movements. It is unknown whether stimuli can be applied with electricity (possibly even subcutaneously), with air pressure or temperature. If such possibilities are shown, they too are part of our invention, so they meet the requirements of this.
  • the stimuli are predominantly exercised with several partial stimuli to enhance the stimulus effect. They can be directed to any stimulus positions of the body.
  • our invention also provides parameter settings for the stimuli, which focus on the speed and intensity of the stimuli and partial stimuli, the number of partial stimuli that make up a stimulus, on the intervals between the partial stimuli, the length of the partial stimuli, the direction of the partial stimuli and the like.
  • a [a] can have several meanings in context, so it is up to the user to establish the connection to the right word with his shorthand knowledge. This knowledge is not required if the user knows the rules of stimulus differentiation.
  • the subject area "geography” could have a special stimulus characteristic, so that [s] means a city and [1] a country. As a result, the city of New York could be communicated with [sy] and the country Austria with [Ia].
  • G2 INTEGRATED DISPLAYS ( Figure 7C): These displays are permanently connected to organizers and any other devices.
  • G3 CONTINUOUS DISPLAY DISPLAYS WITH THE USER ( Figure 9): Displays are provided on finger cots, gloves, cuffs, tapes, or any other devices to read longer texts, to continuously control written texts, and to communicate with others for extended periods of time. You are permanently connected to the receiving points of the reader.

Abstract

L'invention concerne un procédé de saisie de données sur un clavier dont les touches sont associées à certains caractères d'un jeu de caractères. Le nombre des touches est inférieur au nombre de caractères du jeu de caractères et le jeu de caractères contient de préférence des signes de ponctuation. On obtient une amélioration de la convivialité du fait que des séquences de frappe de touches correspondant à des séquences de caractères, qui sont impossibles ou improbables dans le contexte des données à saisir, sont utilisées pour le codage de caractères ou de séquences de caractères qui ne sont pas attribués à une touche.
