Description
Technical field
The utility model relates to a kind of ten button set keyboards, belongs to computer fittings apparatus field.
Background technology
Keyboard is as one of input equipment of computer, and utilization rate is very high, can realize fast word input and the control function to main frame after keyboard is connected with main frame; Our conventional keyboard key-position used in everyday is numerous, needs continuous moveable finger position during use, can cause the fatigue of finger and wrist after long-time use, even can cause wrist disease.In recent years also produce a series of keyboards and take ergonomics as basis, the facility of finger key when adaptation user uses.The design of existing keyboard is used more difficult for disturbance people.Current traditional keyboard adopts the mode of operation of an input signal of a key now, the quantity that increases every grade of defined input signal just must increase bond number, so not only increased keyboard area, also increase its keystroke used time coefficient, also increased the difficulty of memory key mapping and operation simultaneously.Although traditional keyboard need not separately be remembered a set of symbol, memorize mechanically the key mapping of each symbol, even if remembered key mapping, reach skilled operation degree also much more difficult for disturbance people.
Tradition input method is for twenty-twenty popular crowd's design, and therefore traditional inputting character code pattern and input method system function are not considered dysopia user's demand.What most of blind persons learnt when learning Chinese characters is the braille system for blind person's design, do not understand the literary style of each Chinese character yet, therefore spelling and the button rule in traditional input method all needs disturbance people to relearn, and can cause the great learning curve of blind person user.Secondly, tradition input method system always presents the Search Results after input according to the outward appearance of Chinese character, and blind person while using computer adopt more read to shield software, thereby blind person is when using conventional input method and conventional keyboard and often without any suggesting effect, cannot distinguish phonetically similar word homonym.Braille is a kind of word system that is shown, touched for finger knowledge by salient point designing for blind person's feature.This word system is to be invented by French blind person L. Blair in 1824, after obtain internationally recognized, and with Blair's naming.Braille is comprised of 63 coded characters, and each character is arranged in a rectangle that has 6 some positions by a little of 1～6 projection.In order to confirm 63 different point types or Braille, during several somes position, be 1-2-3 from top to bottom from left to right, 4-5-6 from top to bottom from right to left then.The every trade braille of these projections on ground paper, can touch and read gently with finger.< < Blair character list > > can show the formation of each character and its simplest meaning.Hand-written braille first will a standby metal or the braille letter stencil made of plastics and special-purpose vertebra pen.Paper is placed in the middle of letter stencil, with the first letterweight of stylus, in the alveole on lower plywood or become salient point, or becomes embossment shape, by Blair's character, write from right to left; Paper is turned over, and point just upward, is read from left to right.Braille also available special machine is produced.The new braille that China announced in nineteen fifty-three, belongs to phonetic system, has used for reference 6 systems of Blair's embossment.From the design arrangement of Blair's braille system, there are three large features: be first between letter character, mutual contact, contributes to memory on a position; Next is to represent a conventional word or monogram with a symbol, has shown the essence of the symbol of word, and phoneme is a kind of means; That punctuation mark wherein, various designated symbol and dummy suffix notation are all to belong to the letter symbol of expressing the meaning again.
In sum, information age blind person using computer network exchanges and learns is very important demand, the existing conventional input equipment for normal visual acuity user is also not suitable for blind users use, there is no at present the effective keyboard input technology for blind person user yet, the invention is inspired by Braille, aim to provide the keyboard for blind person of a kind of button and braille systems compliant, button can provide the word inputs such as Chinese character.In addition conventional keyboard takes up space larger, the general corresponding 1-2 function of button of conventional keyboard, portable poor, in fact can realize with the alternative conventional button of a small amount of button by formulating the rule of combination of button, the set keyboard of this small amount of button also can be used for the input control in special occasions etc.
