具体实施方式 Detailed ways

[0020] 下面结合附图和具体实施例对本发明做进一步详细的说明。 [0020] conjunction with the accompanying drawings and the following specific examples further illustrate the present invention in detail.

[0021] 如图1所示为本发明一种手持电子设备中手写输入的检测方法的工作流程图。 [0021] FIG. 1 shows a flowchart of the present method for detecting the handwriting input electronic device of the present invention is a handheld. 手持电子设备包括触摸显示器和感光装置,包括: The handheld electronic device includes a display and a touch sensitive apparatus, comprising:

步骤S101,获取对触敏显示器的接触,按照所述接触的移动,在触敏显示器上显示所述移动的移动轨迹; Step S101, the obtaining of the contact touch-sensitive display, according to the moving contact, moving the movement locus displayed on the touch-sensitive display;

步骤S102,当检测到所述接触与触敏显示器脱离,启动感光装置进行检测; Step S102, when the detected contact with the touch-sensitive display from the start of the photosensitive detection means;

步骤S103,当感光装置检测到预设的动作轨迹,则对所述移动轨迹进行识别,得到输入标的,并将所述输入标的在文字显示区显示。 Step S103, the photosensitive device detects when a predetermined movement trajectory, the trajectories of the identification, give the subject input and displayed in the input character display subject region.

[0022] 其中,步骤S102在其中一个实施例中可以省略,只采用步骤SlOl和步骤S103也可以完成本发明所要解决的技术问题。 [0022] wherein, in the step S102 in which an embodiment may be omitted, and only use the steps SlOl to step S103 to be completed technical problem to be solved by the present invention. 然而,增加了步骤S102,感光装置仅在接触到所述接触与触敏显示器脱离时启动。 However, increasing the step S102, in contact with the photosensitive means to start only when the contact with the touch-sensitive display disengaged. 用户在用手写输入时,在书写笔画时,所述接触与触敏显示器保持持续接触,只有当用户输入完毕,或者输入另外的笔画时,所述接触才会与触敏显示器脱离。 When a user inputs handwritten, when writing stroke, the contact maintain continuous contact with the touch-sensitive display, only when the user input is complete, or enter additional strokes before the contact with the touch-sensitive display disengaged. 因此在用户输入笔画时,可以关闭触摸显示器,仅在接触脱离时启动,则一方面可以节省能源,另一方面可以减少出错,避免用户在输入时无意做出预设的动作轨迹被感光装置检测,造成出错。 Therefore, when a user input stroke, a touch display can be turned off, activated only when out of contact, energy can be saved on the one hand, on the other hand can reduce the error, the user avoid inadvertently made at a predetermined input operation by the photosensitive means for detecting the track , resulting in an error.
