Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
Present embodiment provides a kind of gesture identification method, comprises the steps:
The very first time parameter that S1 identification brightness changes;
The second time parameter that the S2 decipherment distance changes;
S3 compares T1 and T2, judges current gesture according to presetting rule.。
It will be understood by those skilled in the art that portable terminal can produce different electric signal and as the external signal of user's input described portable terminal be controlled according to the difference of gesture.The operation that described different electric signal is controlled portable terminal is state of the art, no longer gives unnecessary details here.

S22 detects the current distance D that is identified between object and the recognition means;
The more described current distance D of S23 and described distance parameter threshold value D0, when D is less than or equal to D0, execution in step S24;
T2 detection time of S24 record current distance D is as the second time parameter T2 of change of distance.
Described S3 compares T1 and T2, judges current gesture according to presetting rule, comprising:
When very first time parameter is before the second time parameter, judge that hand slides along the direction from the light sensor to the displacement transducer; When very first time parameter is after the second time parameter, judge that hand slides along the direction from the displacement transducer to the light sensor.It will be appreciated by those skilled in the art that; so just realized utilizing brightness to change reaching brightness change threshold and distance to reach the precedence of the time of distance parameter; determine the direction that gesture moves; those skilled in the art can manage and connect; can preset the operation that is complementary with gesture, thereby realize that controlling portable terminal according to the motion track of user's hand or gesture carries out different operations.
