参考图2和图3所示,以移动终端输入为例,该系统在进行汉字输入过程中,如果起初使用的是虚拟鍵盘榆入方式榆入,继而要转换成利用手写输入方式,可以通过手写榆入装置来完成自动切换,在进行手写输入过程中要转换为虛拟键盘输入方式,也可以通过虚拟键盘输入装置实现,假设在该手机中,默认的输入方法为:虛拟鍵盘输入法,在输入过程中根据实际需要进行两种输入法的自动切换,实现过程如下: 2 and 3, the input to the mobile terminal as an example, the Chinese character input system process is performed, if the first virtual keyboard using elm elm into the ways, and then to convert to using the handwriting input mode, by Yu the handwriting automatic switching means complete, the handwriting input process is performed to convert a virtual keyboard input mode, a virtual keyboard may be realized by the input device, it is assumed in the handset, the default input method: a virtual keyboard input method, the input process is automatically switched to actual needs two kinds of input method, the process is as follows:

步骤101:在手机应用程序启动时,启动虛拟鍵盘输入,加载虛拟键盘; Step 101: when the phone application startup, start the virtual keyboard input, load the virtual keyboard;

步骤102:触笔点触虛拟鍵盘上的掩建,开始进行汉字输入,系统接收虛拟鍵盘输入的信息,并对输入信息进行辨认、组合,生成可能的选择项, 再根据虛拟键盘输入信息确认的选定的汉字输出到触摸屏上显示; Step 102: the virtual mask built stylus touch keyboard, character input start information, the system receives a virtual keyboard input, and an input of identification information, combined, generate possible option, and then based on the virtual keyboard input information confirmation output selected characters onto the touch screen display;

例如:输入"促,,,利用触笔点触虛拟键盘上的"cu",然后点触确定键,系统接收输入信息并进行分析处理,将可能的汉字输出,在触摸屏上显示"促粗簇醋",再次点触"促"输入信息,将选定结果传送给系统, 系统根据选定结果输出,在触摸屏上显示"促"。 For example: Enter "pro ,,, touch the stylus on the virtual keyboard" Cu ", and then touch the OK button, the system receives and analyzes input information process, the possible output characters, displayed on the touch screen" tiger stripes pro vinegar ", again tap" promoting "the input information, the selected result is transmitted to the system, the system output according to the selected result is displayed on the touch screen" pro. "

步骤103:触发手写输入,完成"进"的输入,其实现具体为: Step 103: Trigger a handwriting input completed "in" input, which is implemented in particular:

步骤1031:检测到手写触笔在触摸屏的手写区域上按下; Step 1031: detecting handwriting stylus is pressed on a handwriting area of ​​the touch screen;

步骤1032:设定第一设定距离,判断触笔在指触定时时间内是否在手写输入区域内的移动距离大于第一设定距离,如果是,则自动切换到手写输入状态,如杲否,另行处理; Step 1032: setting a first predetermined distance, the stylus is determined whether the time-to-touch timing of the moving distance in the handwriting input area greater than the first predetermined distance, if so, automatically switches to the handwriting input state, such as whether Gao , dealt with separately;

其中:触笔的移动距离是通过计算触笔在指触定时时间内位置坐标的变化计算得到的; Wherein: moving the stylus from the stylus is determined by calculating the change in position coordinates calculated in the time-to-touch timer;

步骤1033:触笔在手写板上书写"进",记录并通过触摸屏显示该输入轨迹,当该字输入已经结束时,根据输入轨迹从点阵识别算法中调用相关算法进行文字识别以及进行其它相关数据的读取、计算和判断处理,选定输入的字为"进"后,将结果输出给触摸屏进行输出显示。 Step 1033: writing stylus tablet to "forward", and the input trace recording by touching the display screen, when the input word has ended, the call character recognition based on input from the track lattice recognition algorithms as well as other related correlation algorithm data reading, calculating and determining processes, the selected character after the input "in", and outputs the result output to the touchscreen display.

由此,完成了"促进"的输入,在虛拟键盘输入"促"之后,直接识别了手写输入状态的切换,而无需人为设定。 Thereby, the "promotion" is input, after the virtual keyboard "promoting", directly identify the handwriting input switching state, without human settings.

在本步骤中,输入结束是通过设定一个脱触定时时间,并判断触笔脱离写字板的时间大于脱触定时时间来确定的。 In this step, the input end of the contact is off by setting a timer time, and determines whether the stylus from the tablet is longer than the off timing of the touch-determined time.

步骤104:若在手写输入过程中,用触笔点击触摸屏,使其接触时间大于虚拟点触时间,则自动退出手写输入方式,切换到虛拟鍵盘输入方式,可以继续利用虚拟鍵盘输入。 Step 104: If the handwriting input process, click on the touch screen with a stylus, making it longer than the contact time of the virtual touch, the handwriting input mode automatically exit to switch to the virtual keyboard input mode can continue using the virtual keyboard.
