Description

a text input keyboard

Technical field

The invention relates to a character input keyboard, in particular to a text input keyboard with regular arrangement of alphabet keys and ergonomics of keys and keypads. Background technique

The layout of the keyboard stems from the English typewriter that existed about 300 years ago. It is conducive to Western Pinyin input. It was originally invented for the use of Pinyin texts such as English. As we all know, the letters of the computer keyboard are arranged as QWERTY... simply because the early English typewriters were forced to be arranged for technical reasons, and the invention of the computer has caused the original "technical reasons" to cease.

A prior art text input keyboard includes a housing, a circuit board mounted within the housing, wires connected to the output circuitry on the circuit board, and a plurality of keys disposed on the front side of the housing.

The arrangement of the keys on the keyboard, in terms of its function, the keys on the keyboard can be divided into four key areas, or four key areas, respectively: typewriter keypad, positioning editing keypad, numeric keypad area and function keys Area, see Figure 1 prior art keyboard and keypad.

In the typewriter keypad, the keyboard letters are arranged, such as the following three lines of letters:

Q W E R T Y U I 0 P

A S D F G H J L Z X C V B N M

This is the order in which all computer keyboard letters or English typewriter keyboard letters are arranged. It is difficult to remember and difficult to master the 26 characters in this random arrangement. In the 1870s, Shores was the largest manufacturer of typewriters at the time. Because the mechanical process was not perfect at the time, the rebound speed of the word key after the hitting was slow. Once the typing speed of the typist was too fast, the two word keys were easily twisted together, and the hand must be carefully They are separated, which seriously affects the speed of typing. One engineer suggested: The reason for the typewriter's twisting is that on the one hand, the word key rebounds slowly, and on the other hand, the typist is too fast. Since it is impossible to increase the rebound speed, why not reduce the typing speed? There are many ways to reduce the speed of a typist. The easiest way is to upset the 26-letter order and put the more common letters under the clumsy fingers, for example, the letters "0", "S", 〃A" It is very frequently used, but it is hit by the most clumsy right-hand ring finger, left-hand ring finger and left-hand little finger. The lower-frequency ' 'v', Ί "IT and other letters are responsible for the most flexible index finger. This "QWERTY..." combination keyboard was born and gradually finalized. Later, due to the development of material technology, the word key bounce speed was much faster than the typist keystroke speed, but the keyboard alphabetical order was not changed.

There have been several major changes in the keyboard. Every change in the keyboard is accompanied by system software. Developed and developed. In 1995, the advent of Windows 95 marked the arrival of the operating system era of the graphical interface. The 101-key standard keyboard was also transformed into a 104-key "Win95 keyboard". Four years later, the keyboard changed and became The 107 button, also known as the "Win98 keyboard". However, the 104 keyboard is good, the 107 keyboard is also good, in addition to a few more optional key functions, the overall layout of the Dos era 101 keyboard layout concept.

At present, the typewriter keypad of the keyboard, the alphabetic keys are arranged as described above, and are divided into three rows and ten columns. Each row contains ten keys, and ten keys per row are arranged side by side. From top to bottom, in order is the first line: QWERTYUI 0 P from left to right, including ten letter keys; Second line: ASDFGHJKL from left to right, contains a total of nine letter keys, the tenth key by The punctuation key complements ten keys, the punctuation key is the tenth key from left to right; the third line: from left to right, ZXCVBNM contains seven alphabetic keys, and the eighth, ninth, and tenth keys are complemented by punctuation keys. Ten keys, punctuation keys are used from left to right for the eighth, ninth and tenth keys. Each column is bottom-up, tilted to the left, and each column contains three letter keys.

In the prior art keyboard input, referring to Fig. 1, the typewriter keypad of the keyboard can be further divided into a left-hand letter keypad and a right-hand letter keypad. The basic keys of the keyboard are the F and J keys located in the typewriter keypad. During the letter input process, the left thumb, the ring finger, the middle finger and the index finger are first placed on the ASDF letter keys of the typewriter keypad, and the right index finger, middle finger, ring finger and little finger are respectively placed in the JKL letter key of the typewriter keypad and located on the right side adjacent to the L. The letter key is on the punctuation key. Bottom-up, the left-handed little thumb is responsible for the ZAQ three-letter key, the left-hand ring finger is responsible for the XSW three-letter key, the left-hand index is responsible for the CDE three-letter key, the left-hand index finger is responsible for the VFR (fourth column) three-letter key and BGT (fifth Column) three-letter key, left-hand index finger is responsible for six-letter key; right-hand index finger is responsible for NHY (sixth column) three-letter key and MJU (seventh column) three-letter key, right-hand index finger is responsible for six-letter key, The right middle finger is responsible for one punctuation key and KI two letter keys, the right hand ring finger is responsible for one punctuation key and L 0 two letter keys, and the right hand little thumb is responsible for two punctuation keys and P-letter keys. It can be seen that, according to the current letter key distribution mode of the keyboard typewriter keypad, during the keyboard input process, the left hand is responsible for the left hand letter keypad containing fifteen letter keys, and the right hand responsible right hand letter keypad contains eleven letters. The key and the four punctuation keys. From the perspective of the letter key, the left and right hand letter divisions are extremely unbalanced. Usually, the right hand is more flexible than the left hand, while the relatively inflexible left hand is responsible for more than the flexible right hand. The responsible letter key, the ratio of the left-handed letter key to the right-handed letter key is 15: 11, the imbalance of the left and right hand-key divisions will greatly affect the letter input rate.

In addition, the "Back" button is in the upper right corner of the keyboard typewriter keypad, which is inconvenient in the backspace deletion operation and affects the input rate.

In addition, in the prior art keyboard, the distance between the right and left hands is too close, the operating posture makes the chest unable to stretch, and the long-time operation is liable to cause a feeling of poor breathing and fatigue.

Therefore, the prior art text input keyboard has an irregular arrangement of alphabetic keys, which is difficult to remember. Recalling is difficult to be skilled; the left and right hand letter keys are unbalanced, which greatly affects the letter input rate; and the back key is unreasonable, affecting the input rate and the distance between the right and left hands is too close, which may cause defects such as poor breathing and fatigue. .
