Then,, in the time proceeding to write, judge on the either direction axle of first direction axle, second direction axle, third direction axle and fourth direction axle, whether there is the second Contact recognition point.In the time there is the second Contact recognition point, determine the moving direction of the second contact point with respect to first make contact.
Then, judge whether described the second Contact recognition o'clock exists velocity variations with respect to the first Contact recognition point.
In the time writing continuously, need continuously the velocity variations between the rear Contact recognition point of judgement and last Contact recognition point on touch-screen.Because in the time writing, while particularly writing with writing brush, because there are the different action of writing such as start to write, start writing, therefore between each Contact recognition point, certainly there is the variation of speed, need to detect the variation of this speed and determine the action of writing, thus the input content with certain effects corresponding with this input action.
Specifically, in the time there is velocity variations, according to the size of speed at ellipse corresponding to respective direction plot on X axis as input content.For example, when the variation of speed detected on a direction axle time, can, according to the size of speed, draw an ellipse on this axis of orientation, this oval parameter depends on the now size of speed.Speed is large, and ellipse is slightly longer, and speed is little, and ellipse is slightly smaller.Little is exactly circular to a certain extent.That is to say, in the time not there is not velocity variations, draw circular as input content using the distance between these two Contact recognition points as diameter.
Then,, for each axis of orientation, detect and whether have continuous multiple contact Contact recognition points.
When there is the 3rd Contact recognition point on arbitrary axis of orientation time, judge the acceleration change between the first Contact recognition point, the second Contact recognition point and the 3rd Contact recognition point.In the time there is acceleration change, calculate acceleration magnitude and direction that the acceleration calculation on four direction axle is made a concerted effort, and according to the acceleration magnitude of making a concerted effort and the direction that calculate, draw corresponding ellipse as input content.
On the other hand, in the time not there is not acceleration change, illustrate that now brush writing stops.Now, can be according to translational acceleration, speed and the resultant acceleration information calculated, draw special graph as input content.For example, on moving direction, draw a sharp triangle, oblong etc., as a receipts vigour of style in writing shape of writing brush.
In addition, in drawing various figures, adjust by the mode of drawing tangent line filling for the edge camber line of various figures.For example, when the figure of these identification points (circular, oval, the special vigour of style in writing) is drawn, pen, after a direction stops, writing to entirety the method that the edge camber line in region is filled by picture tangent line, the shape of mellow and full font stroke, makes it have better display effect.
In another embodiment, also can be by content comparison pre-stored in the content of input and database, wherein, in described database, pre-stored content has multiple predetermined display effect.For example, can, according to the calligraphy type of writing brush (as lishu, running hand, rapid style of writing etc.), set up in advance different databases, in this database, store Chinese character or the various stroke shapes (as point, horizontal stroke, slash, right-falling stroke etc.) of corresponding calligraphy type.
Then, according to the acceleration of each identification point of identifying in writing process, speed, resultant acceleration direction, a moving direction, with pen with touch-screen contact area etc., the calligraphy type of identifying current input is any.Or user also can preset in menu needs any calligraphy type.
Then, the content of the current input of user is identified, and mated with the data in database, thereby recall typical writing brush shape in database as input content, thereby further improve the effect of brush writing.
