Abstract
The invention relates to the corresponding technical field of handheld electronic equipment, in particular to a detection method and a detection system of the handheld electronic equipment. The handheld electronic equipment comprises a touch displayer and a photosensing device. The detection method includes the following steps of obtaining contact with the touch-sensitive displayer, displaying a moving track of movement on the touch-sensitive displayer according to the movement of the contact, recognizing the moving track when the photosensing device detects a preset moving track, obtaining an input sign and displaying the input sign on a word displaying area. By means of the detection of the moving track through the photosensing device, the detection method and detection system of the hand input of the handheld electronic equipment judges whether the hand input is finished or not. Due to the fact that a special action is used for judging, recognition is conduced only when the hand input is finished.

Fig. 2 is the construction module figure of the detection system of handwriting input in a kind of hand-hold electronic equipments.
Embodiment
The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.
Be illustrated in figure 1 as the workflow diagram of the detection method of handwriting input in a kind of hand-hold electronic equipments of the present invention.Hand-hold electronic equipments comprises touch display and photosensitive device, comprising:
Step S101 obtains the contact to touch-sensitive display, according to the movement of described contact, shows the motion track of described movement on touch-sensitive display;
Step S102 breaks away from when described contact and touch-sensitive display being detected, starts photosensitive device and detects;
Step S103 when photosensitive device detects default movement locus, identifies described motion track, obtains inputting target, and described input target is shown in the word viewing area.
Wherein, step S102 can omit in an embodiment therein, only adopts step S101 and step S103 also can complete technical matters to be solved by this invention.Yet, having increased step S102, photosensitive device only starts when touching the disengaging of described contact and touch-sensitive display.The user is when using handwriting input, and when stroke writing, described contact and touch-sensitive display keep continuous contact, only has and inputs completely as the user, and when perhaps inputting other stroke, described contact just can break away from touch-sensitive display.Therefore when user's entering stroke, can close touch display, only start when contact breaks away from, can save the energy on the one hand, can reduce on the other hand and make mistakes, avoid the user to be not intended to make default movement locus when input and detected by photosensitive device, cause and make mistakes.
Therein in embodiment, the corresponding Chinese character of described input target for obtaining after described motion track is identified.
Therein in embodiment, the corresponding character image of described input target for obtaining after described motion track is identified, the described photosensitive device of working as detects default movement locus, described motion track is identified, obtain inputting target, and the step of described input target in word viewing area demonstration specifically comprised:
