Description

Two-finger gesture text input method Technical field:

The invention relates to a two-finger gesture text input method. Background technique:

With the popularity of touch screen technology in the field of electronic products, software virtual keyboards using touch screen technology, also known as soft keyboard text input methods, have also been widely used. However, the soft keyboard input method is currently known to have a poorer experience than a conventional mechanical keyboard. Specifically, since there is no tactile sensation of the traditional mechanical keyboard keys, the soft keyboard user cannot blindly play only by hand when inputting characters, and the visual accuracy must be ensured by the visual, and the user needs to pay attention to the text editing area which is far away from each other. And the position of each key position of the soft keyboard, the input efficiency is low. Especially for tablet computers, because the user often uses two hands-held grips in the absence of a support such as a desktop, when the user inputs text in a double-handed manner, the thumb has an excessive operating distance during the input process. This also reduces input efficiency.

For example, the computer input method of a text of the application (patent) No. CN95111187. 6 and the corresponding keyboard are characterized in that the one-dimensional order of the keyboard plane is sorted by the syllable consonant alphabet or the number of strokes from the radical side. For the order, another dimension of the keyboard plane is in the order of the number of vowels or the number of syllables or the number of strokes.

For example, the application (patent) number is a handwritten text input method of CN94109513. 4, when handwriting input text, it is decomposed into sub-characters of a~f, and adjacent sub-characters of sub-characters a~f The specified number is combined and recognized as 1 text. In the handwriting character input method for detecting the handwriting features of each stroke of the character input by the handwriting, and the handwritten character input method for recognizing the subcharacter by using the detected feature amount and combining the subcharacters, a line cutting rule and a sub-character cutting rule are provided. When the stroke is drawn, the input line is judged according to the feature of the stroke, the sub-character and the line cutting rule, and when the input line is the same line as the previously input line, according to the feature of the stroke, the sub-character and the sub-character The cutting rule is used to judge the above sub-characters.

For example, the application (patent) number is a method of inputting an external letter character of CN99101082. 5, which can easily and quickly input a text input method and a device for specifying a foreign letter by performing character conversion on the input predetermined letter. In the method and apparatus thereof, a predetermined alphabetic letter desired in a predetermined alphabetic character that can be directly input is input. At least one predetermined foreign alphabetic character combined with the desired predetermined alphabetic character input as described above in the predetermined foreign alphabetic character that cannot be directly input is called. Select one of the predetermined foreign alphabet characters desired in the at least one predetermined foreign alphabet. The character conversion from the desired predetermined alphabetic character input as described above to the selected desired foreign alphabetic character is performed. For example, the application (patent) number is CN03112279. 5 digital keypad and pinyin text input method, and belongs to the technical field of input method of computer numerical keypad of pinyin text. The all-in-one numeric keypad includes alphanumeric keys, symbol keys, and function keys. Several alternate keys are provided to arrange convenient keys or touch the mouse and its left and right keys, which can replace the current English large keyboard. Among them, the letter in the alphanumeric key is a variable part, which will assign each letter to the corresponding number key according to the letter code of different characters, to satisfy any kind of text for computer numerical input, and the keyboard arrangement format is vertical And horizontal. The coding method in the pinyin text input method includes three parts: letter coding, word coding, and word coding.

However, none of the above patents and technologies solve the technical problem of single-finger text input. Summary of the invention:

In order to overcome the problem that the known soft keyboard experience is poor and the input efficiency is low, the present invention provides a two-finger gesture text input method, and the user only needs to indicate the single-finger gesture in two active areas that are convenient for single-finger operation. The different characters are determined and input by the difference in the direction and distance of the single-finger swipe. The present invention includes the following steps:

(1) Assigning three numerical variables, such as the angular range value, the distance range value, and the active area number, to the corresponding characters in the font; each character in the font corresponds to a corresponding set of angular range values and distance ranges. The value and the activity area number are three numerical variables; the angle range value is a relative angle between the finger lifting starting point coordinate and the finger pressing point coordinate; the distance range value is between the finger lifting starting point coordinate and the finger pressing point coordinate Relative distance; the active area number is the number of the active area where the finger presses the point;

(2) When the user's finger is pressed in the active area on the touch screen, the coordinates of the pressed point and the number of the active area of the pressed point are obtained;

(3) When the user's finger is lifted by a distance on the touch screen and raised, a lifting point coordinate is obtained;

(4) When the following three values are used: the relative angle between the finger lift start point coordinate in step (3) and the finger press point coordinate in step (2), the finger lift start point coordinate and step in step (3) ( 2) The relative distance between the coordinates of the finger press point and the number of the active area of the finger press point in step (2) match the one of the characters in the font that has been set in step (1). Enter the character for the range of values required.

The present invention and the existing soft keyboard text input need to visually determine the exact position of the button. The invention replaces the fixed key position with the relative direction and distance, which greatly reduces the requirement of the text input on the user's operation precision and text input skill. It simplifies the process of text input, and can realize fast input by hand, which greatly improves the efficiency of text input, has wide application range, and has strong practical value.
