Embodiment 1

[0017] refer to Figure 1A , which depicts a portable electronic device 100 suitable for the present invention, which is equipped with a touch screen. The touch screen includes a user input area 101, an area 103 for displaying stroke sequences that have been input, and an area 104 for displaying candidate characters (words). First, the user presses the touch point (with a finger or a touch pen) in the area 101 and moves laterally and then releases it, and the trajectory is 110 . Tracks can be displayed on the screen or not.

[0018] When the user releases the touch point, the system can determine that the stroke corresponding to this input is horizontal by detecting the track of the touch point. In the present embodiment, be divided into horizontally, vertically, cast aside, dot (or press down), fold five kinds of strokes altogether. There are many ways to judge strokes. For example, analyze the starting point and end point of the trajectory and the trajectory it has experi...

Embodiment 2

[0023] In this embodiment, handwritten strokes can be combined with pinyin input. When the pinyin input has many candidate words with repeated codes, the handwritten strokes can be used to quickly filter the candidate words. When a user encounters a word whose pinyin is not known, he can directly write the word with a stylus without switching input methods or interfaces.

[0024] first reference Figure 2A , which depicts a portable electronic device 200 using the present invention, which is equipped with a touch screen. In the upper half of the screen is a text input area 202, and in the lower half of the screen a soft keyboard 201 is displayed. In this embodiment, the soft keyboard 201 has a single-key Qwerty layout, and each key represents a letter. The user inputs pinyin by clicking each key on the touch screen. It is worth mentioning that in other embodiments of the present invention, other keyboard layouts can also be used, such as the 9-key layout of a traditional m...

Abstract

The invention relates to a method for inputting and filtering characters by handwritten strokes on a touch screen, which comprises the following steps of: analyzing the input as stroke input by detecting a contact moved by a user on the touch screen; rapidly filtering a candidate word list generated by other previous input methods; and helping the user to rapidly find candidate words.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to the technical field of electronic equipment information input, and specifically refers to a method for realizing handwritten stroke input on a touch screen. Background technique [0002] In modern life, with the continuous development of integrated circuit technology, various touch screen electronic devices have appeared, such as mobile phones, PDAs, navigators and so on. These touch screen electronic devices can perform more and more user functions. For example, sending and receiving emails, reading and editing documents, surfing the Internet, etc. With the continuous improvement of functions, these electronic devices have become more and more important tools in people's lives. However, how to input text quickly and efficiently on these devices has become a big challenge. [0003] For Chinese input, this challenge is particularly obvious. Because the repetition rate of mo...
