Description
Technical field
The invention belongs to technical field of mobile terminals, relate in particular to a kind of portable terminal hand-written inputting method, device and portable terminal.
Background technology
Equipment with full frame handwriting functions all has some function buttons on the screen when entering full frame hand-written state, as various input methods, and punctuation mark, literal and space carriage return etc., these zones may be defined as input panel.
Have full frame hand-written equipment at present, under full frame hand-written pattern, general the first stroke falls into above-mentioned input panel zone and does not enter hand-written state, in case when entering hand-written state, the input panel zone also can effectively receive hand-written information.When hand-written, the general the first stroke of user is started to write and is all dropped on the screen upper half full frame, and this is owing to the decision of Chinese-character writing order.The universal law of Chinese-character order of strokes is: earlier horizontal back is perpendicular, casts aside afterwards earlier and presses down, in the elder generation after under, from left to right, from outside to inside, by the centre to both sides.
When the bottom half of input panel at screen, it is unaffected substantially the first stroke to be started to write.Yet when the below of screen is arrived in cursor positioning, input panel will be positioned at mobile terminal display screen curtain upper half, input panel can not be as the first stroke scope of starting to write like this, and this has greatly influenced the hand-written of user, has promptly limited the first stroke scope of starting to write largely.
Summary of the invention
