Embodiment 1

[0035] This embodiment provides a formula input method, which includes the following steps:

[0036] The voice input signal is obtained through the voice input unit.

[0037] The speech recognition unit is used to obtain formula elements matching the speech input signal from the prestored formula element table, wherein the formula element is the content unit used in the formula, and the formula element table stores the corresponding relationship between the formula element and the speech input signal.

[0038] Input the acquired formula element to the cursor position.

[0039] In the formula input method of this embodiment, formula elements are formed by voice input, so as long as it can "speak" the formula to be input, no special learning is required, it is convenient and easy to use, simple to operate, and has high input efficiency. High, good accuracy, and the input formula is given directly, the result is intuitive, easy to modify, does not need to use handwriting input d...

Embodiment 2

[0041] This embodiment provides a formula input method, such as figure 1 As shown, it includes the following steps:

[0042] S01, preferably, construct the formula element table, store the corresponding relation of formula element and voice input signal in this formula element table, and formula element is the content unit used in the formula; That is to say, as shown in table 1, collect Various content units (formula elements) commonly used in the formula, and a database is established to correspond these content units with certain voice input signals.

[0043] Table 1. Schematic diagram of the corresponding relationship in the formula element table

[0044]

[0045]

[0046] Among them, "formula element" includes any content unit that is more commonly used in scientific and technological formulas. Table 1 lists only a few examples; formula elements can be letters, numbers, symbols, graphics, trigonometric functions, units of measurement, chemical formulas, structural ...

Embodiment 3

[0087] The present embodiment provides a formula input system, which includes:

[0088] The voice input unit is used to acquire voice input signals; it can be a conventional device such as a microphone.

[0089] The speech recognition unit is used for recognizing speech input signals.

[0090] The formula element obtaining unit is used to store the formula element table, and according to the recognition result of the speech recognition unit, obtain the formula element matching the speech input signal in the formula element table, wherein the formula element is the content unit used in the formula, the formula element The table stores the correspondence between formula elements and voice input signals.

[0091] The formula element input unit is used to input the obtained formula element to the position of the cursor.

[0092] Preferably, the formula input system of this embodiment may also include a mode switching unit, which is used to switch the formula input system between...

Abstract

The invention provides a formula input method and system, belongs to the technical field of input type setting, and can solve the problems that a conventional formula input technology is difficult to grasp, results are not straightforward, the operation is troublesome, the efficiency is low, the accuracy is low, or the formula input technology depends greatly on other factors. The formula input method includes that a voice input signal is obtained by a voice input unit; a voice recognition unit is used for obtaining a formula element which is matched with the voice input signal from a pre-stored formula element table, wherein the formula element is a content unit which is used in a formula, and a corresponding relation between the formula element and the voice input signal is stored in the formula element table; and the obtained formula element is input to the position of a cursor. The formula input system comprises function units corresponding to the steps in the formula input method. The formula input method and system can be used for imputing formulas into electronic devices, in particular to an RIA (rich internet applications) system based on HTML5 (hypertext markup language 5).

Description

technical field [0001] The invention belongs to the technical field of input typesetting, and in particular relates to a formula input method and system. Background technique [0002] With the popularization of electronic equipment, Internet education technology, etc., the operation of inputting formulas into electronic equipment is becoming more and more common. Since formulas often use many special contents (such as Δ, ≌, ±, etc.) and formats (such as the horizontal fractional line divides the content into upper and lower parts), and these special contents are numerous, it is difficult to input directly with the keyboard, etc., so to The operation of inputting formulas in electronic equipment is much more complicated than that of inputting conventional linear texts (such as Chinese characters, English words), and special methods are required. The existing formula input methods include the following three: [0003] The first is a script command input method, that is, a sp...
