Dot matrix character and other information collection

1. Invisible calculation realization (blind typing without feedback),
2. Dot pixel realization,
3. Characters,
4. Chinese characters,
5. Chinese information system.

Directly from the two tools of the screen and the keyboard, like two mirrors, indirectly looking at the mainboard. This mirror has colors, and the colors have basic colors, and dot pixels belong to the basic color dots. The sequence relationship between dot pixels and characters. Using dot pixels as the basis for describing everything, and then realizing the secondary pixel realization of dot pixels based on the character standard. Tending to give priority to dot pixels over character pixels. The difference between keyboard digital input and character input, established through fixed digital pixels first, and then other characters are constructed on the basis of digital characters. The content of human actively using physical properties and the agreement and cooperation between people.

Input realization,
Output realization,
Calculation realization,
Dot pixel realization,
Character realization.

Considering the range of dot matrix size relative to human eye recognition requirements, and dot matrix or vector that should change with the screen size. Eyes of children, children, teenagers, young people, middle-aged people, elderly people, eye weakness, eye defects. Normal range of human eyes, auxiliary magnification range of human eyes, comfortable and beautifying range of human eyes, multi-dimensional information auxiliary range of human eyes' five senses (each character emits the sound of the dictionary, and can be selected to play repeatedly for recognition).

Characters and strokes, mathematical characters and foreign characters are also classified as stroke content. Totems, oracle bone inscriptions and the problem of stroke decomposition, the problem of the whole and the decomposed individuals. All Chinese characters are counted by strokes, which belong to a combination of stroke quantities, and some even have the same number of strokes, with different genetic blueprint differences.

Symbol graphics intermediate character set. Phonetic character set. Pinyin character set (including future more abundant pinyin extensions). Chinese character set. Chinese information system character set. Universal layer construction is carried out between character sets and digital coding, the connection of human concepts between character sets is established, and digital coding is connected with binary and level hardware.

Driverless display?
Driver-based display

The relative relationship between the screen and the character unit, size, vertical and horizontal coordinates, and spatial position.
The relationship between characters and dot pixels, the same standard.
The relationship between the screen and dot pixels.
The recognition standard of the computer mainboard for the display (graphics card driver?).
The total amount of performance energy for full screen display and full dynamic, the energy saving efficiency based on the total amount, graphic characters, integrated hardware characters.

The order of characters in rows, columns, up, down, left, right, inside and outside, pure text mode characters. Full-screen characters combined in multiple lines. Multi-screen spatial and temporal book mode.


Location input method
Erbi input method (not knowing pinyin or not knowing the pronunciation of a character is a problem)
Wubi input method
There should also be an input method that directly inputs GB18030 sixteen-bit Chinese characters.

Zhengma input method, maybe its experience and knowledge have a learning effect, but do not rely on its patented software. (60 yuan, built-in in WIN7)
There is a need for continuous emergence of input method updates without patents or that are cheap, accurate, simple and fast.

The largest character is as big as the screen,
the smallest character is invisible,

According to the relationship between distance and vision, we know that when a person measures vision at 2 meters, 1.5 vision can see the orientation of 0.5 cm letters. Converted to 100 meters, 1.5 vision should be able to see the orientation of 25 cm letters.

According to this calculation method, you can multiply the letter size at 0.7 in the vision measurement table by 50 to get the data you want.

The computer is a little upward, keeping a 50 cm distance from the eyes.

2 meters
200 cm / 50 cm = 4 times the range
1.5 vision sees 0.5 letters
0.5 cm / 4 times = 0.125 cm
The character is in the range of 0.125 cm

Uniform grid, the center intersection points of respective diagonals, one or two types of connecting rods between intersection points.

Connecting characters of wood or circuit board.

Intersection patches, connections between adjacent intersection points.
