In recent years, the handwriting input has obtained using widely on the mobile devices such as mobile phone of band touch-screen as a kind of important literal input mode.In daily life; People often are accustomed to from left to right writing continuously the next line literal; But on mobile device; Owing to receive the restriction of touch-screen size, when carrying out handwriting input, people need be in the zone of an appointment (zone that a rectangle frame touch-screen in limits is whole touch screen perhaps) overlapping repeatedly to write script be the literal that from left to right links.Generally be to distinguish different literal through certain time delay under this mode, the user pauses the regular hour after having write a word in other words, is beginning to write next word, and the stroke of former and later two words just can be distinguished by system like this.The another kind of mode of distinguishing the stroke of former and later two words is that two or more handwriting areas are set in touch-screen, writes on different words in the different zones.Which kind of mode does not all meet the custom of the from left to right continuous writing of the daily employing of people.
Here, " stroke " is meant that touching touch-screen from the user with writing pencil begins, to writing pencil break away from the contacting of touch-screen till, the track that writing pencil moved on touch-screen.A stroke possibly represented a literal, and the part of a literal perhaps connects a plurality of literal that pen is write.Provided the example that a stroke is represented literal like Fig. 1; Provided the example that a plurality of strokes are represented literal like Fig. 2; Fig. 2 (a) to (d) has demonstrated the input one by one along with a plurality of strokes of a literal, and recognition engine finally identifies the process of this literal.Provided a stroke representative like Fig. 3 and connected an example of a plurality of literal of writing, recognition engine will be carried out the cutting and the identification of literal automatically.
To this problem; U.S. Pat 6661509 B2 " Automatically scrollinghandwritten user interface for personal digital assistants and the like " have proposed a kind of method; This method lets the handwriting area of appointment in the touch-screen when the user writes; Constantly move left along with user's moving of stroke writing; The stroke of user writing just as automatic transport tape one belt transect that is moved to the left constantly moves left, thereby for the user space of successively writing is provided in limited the writing in the zone of size.The shortcoming of this method is; Although the stroke of user writing is such along with writing to the left side of user moved automatically like being placed on the automatic transport tape, the user is at the stroke of writing the one or more literal of representative, when beginning to write the next one again and representing the stroke of one or more literal; In order to carry out the differentiation between the different literals stroke; Next stroke must write on the right of previous stroke, just like what stressed among the U.S. Pat 6661509B2, must use specific vertical line; Former and later two different words are at interval distinguished in the space of representative separated by a distance, perhaps specific symbol.This just means; The user is in the process of writing; Be that the Far Left that impossible get back to input area at any time begins to write new literal; The user can only be connected on the back (the right) in other words that the previous literal of being write is presented at the position of input area and begin to write new literal, has so both caused the waste in input area space, and the daily writing that does not also meet people is accustomed to.
