Embodiment 1

[0031] see figure 1 , the present embodiment provides a method for determining candidate words based on sliding tracks, the method comprising:

[0032] 101: Extract the positional feature h(i) of the standard sliding trajectory of the word at each sampling feature point i;

[0033] Among them, h(i) is a two-dimensional coordinate point, representing the abscissa and ordinate of each sampling feature point of the standard sliding track of the word on the soft keyboard.

[0034] Wherein, the words may be English words in a lexicon, or pinyin letters corresponding to Chinese characters, and the pinyin letters may be full spelling letters or simplified spelling letters corresponding to Chinese characters, which is not limited in this embodiment.

[0035] Among them, the sliding trajectory data is a data stream with equal time intervals, and its sampling frequency varies with the parameters of the mobile phone touch screen. For example, the sampling frequency can be between 50Hz-2...

Embodiment 2

[0064] see Figure 5 , the present embodiment provides a device for determining candidate words based on sliding tracks, including:

[0065] Word feature extraction module 201, for extracting the standard sliding trajectory of word at the position feature h(i) of each sampling feature point i;

[0066] Wherein, the words may be English words in a lexicon, or pinyin letters corresponding to Chinese characters, and the pinyin letters may be full spelling letters or simplified spelling letters corresponding to Chinese characters, which is not limited in this embodiment.

[0067] Matching template generating module 202, for generating the matching template α (i) of word according to h (i) and the position of the character that forms word;

[0068] Weight template generation module 203, used to establish weight template β(i);

[0069] The input data feature extraction module 204 is used to extract the positional feature f(i) of the user's input sliding track at each sampling feat...

Abstract

The invention discloses a method and an apparatus for determining candidate words based on a sliding path, belonging to the input method field. The said method comprises: extracting a position features (i) of a word standard sliding path on each sampling feature point i; generating a template alpha(i) matching with the said word according to h(i) and the position of characters constituting the word; establishing a weight template beta(i); extracting a position feature f(i) of an inputting slide path of a user on each sampling point; calculating similarity Xs between the user's inputting slide path and the said word's standard slide path according to the f(i),the h(i), the alpha(i) and the beta(i);and selecting a word according to the similarity. The embodiment of the invention can enable a user to determine a candidate word by sliding according to the sequence of the characters to prevent the frequent pressing and lifting operation in a traditional method, and is good for improving inputting efficiency and accuracy rate, thereby improving the user experience.

Description

technical field [0001] The invention relates to the field of input methods, in particular to a method and device for determining candidate words based on sliding tracks. Background technique [0002] Nowadays, touch-screen mobile phones are becoming more and more popular, and everyone is exploring how to improve the input experience on touch-screen mobile phones. [0003] At present, the user presses the keys of the soft keyboard on the touch screen with a finger or a stylus to input each character that forms a word. For example, if the user wants to input the word "dog" through the touch screen, the user presses the button d of the soft keyboard on the touch screen with a finger or a stylus, lifts the finger or the stylus, and then presses down the soft keyboard on the touch screen with a finger or a stylus Press the key o of the touch screen soft keyboard by lifting the finger or the stylus, and then press the key g of the soft keyboard on the touch screen with the finger...
