Example, broadly falls into the scope of protection of the invention.
As shown in Figure 1, it is provided that intelligent terminal's gesture identification method of one embodiment of the present of invention, it includes step
S11-S13:
S11. range sensor is driven to obtain the relative distance of destination object and intelligent terminal and sense duration.
Intelligent terminal is in starting state, when exist object near time, then this object can be judged and identifies.If leaning on
When near object is destination object, then relative distance and the sensing duration of this object with intelligent terminal is measured and record.
Wherein, intelligent terminal is drive recorder, intelligent video camera head, smart mobile phone, panel computer, notebook, vehicle-mounted computer and can
Any one in Wearable portable mobile equipment.Described intelligent terminal all contains arithmetic element, can be to the data obtained
Quickly process, and actively respond.
In a kind of implementation of the present embodiment, described driving range sensor obtains destination object and intelligent terminal's
The step of relative distance and sensing duration comprises the following specific steps that:
Drive range sensor, launch infrared ray;
Its infrared ray running parameter is obtained by range sensor;
Determine whether to there is described destination object by infrared ray sensor;
When for described destination object, according to described infrared ray running parameter, determine this destination object and intelligent terminal's
Relative distance and sensing duration.
Close object is judged, is completed by infrared ray sensor.For close object, it is not necessarily
It is to need identified hand, it is also possible to be the object that need not be identified, such as: plastic bottle, suitcase, medicated cap etc.;This just needs
Carry out a difference.Human body is a unique radiant body, and general human body has constant body temperature, typically at 37 degree, so
The infrared ray about specific wavelength 10 μm can be sent.Infrared ray sensor is according to this feature of human body, left by detecting 10 μm
Right infrared ray, it is possible to judge that close object is the hand of human body, and there is the highest degree of accuracy.Simultaneously as it is red
Outside line sensor measurement is the infrared ray of specific wavelength, and infrared ray that range sensor is launched also is unlikely to this measurement result
Form interference.
It is to say, the hand of human body is when intelligent terminal, intelligent terminal can detect the close of the hand of human body, and
After determining that it is destination object, the relative distance between itself and intelligent terminal can be obtained, and record in the range of this relative distance
Sensing duration.And when the hand that close object is not human body, such as plastic bottle, intelligent terminal then can determine whether that it is not target
Object, will not obtain the relative distance between itself and intelligent terminal and sensing duration, also would not carry out gesture operation instruction
Determine.
In an embodiment of the present invention, measured described relative distance is unlikely to be infinity, its relatively away from
From there is a rational measurement scope.In the present invention, the distance between destination object and intelligent terminal is used often
Family uses custom during intelligent terminal to be limited to.So, described relative distance range preferably from 5 to 10 centimetres.On the one hand
After advantageously reducing this function of startup, owing to opereating specification is excessive, the unnecessary false triggering caused;On the other hand, also have
Profit controls the precision measured, and reduces the requirement to hardware.
In another embodiment of the invention, also comprise the steps:
Time offset value, distance bias is set in advance in arithmetic element;
When getting the relative distance of destination object and intelligent terminal and sensing duration, acquired information is sent to
Arithmetic element carries out pretreatment, for reducing the interference of out of Memory.
User use intelligent terminal carry out gesture input when, the relative distance between its hand and intelligent terminal with
Sensing duration, sense organ is be difficult to hold, and its input will necessarily exist error, simultaneously take account of the probability of false triggering,
In the present embodiment, it is provided that the time offset value of corresponding sensing duration, the distance bias of corresponding relative distance, defeated to its gesture
The sensing duration, the relative distance that enter carry out the rectification on an algorithm, so that the accuracy of its gesture operation instruction determined
Higher.
S12. determine that effective gesture operation instructs according to described relative distance and sensing duration.
In an embodiment of the present invention, the CPU of intelligent terminal obtains according to it described relative distance and sense
Answer duration, so that it is determined that effective gesture operation instruction.Described according to described relative distance and sensing duration determine effective hands
The step of gesture operational order comprises the following specific steps that:
Judge whether described relative distance respectively reaches its corresponding threshold value with sensing duration;
When reaching respective threshold, according further to relative distance and sensing duration coupling gesture mode;
According to the gesture mode matched, determine corresponding effective gesture operation instruction.
In an embodiment of the present invention, different relative distance and the sensing gesture operation instruction corresponding to duration is endless
Identical.It should be noted that, the handedness of different user is different, to the relative distance between hand and intelligent terminal
And sensing duration is differentiated in sensory experience.In an embodiment of the present invention, described threshold value is that user is according to oneself
Custom is arranged, and is conducive to meeting the respective demand of different user, personalized customization.Described threshold value has two kinds, and one is to use
In judging whether what its gesture inputted reaches effective requirement with the relative distance of intelligent terminal, sensing duration;Another kind is then
For judging the gesture operation instruction corresponding to its relative distance and sensing duration.It follows that mainly be used for judging phase with regard to it
Adjust the distance and sense the gesture operation instruction corresponding to duration and launch.
Only relative distance and sensing duration has all reached the threshold value of certain gesture operation instruction, just can trigger this gesture operation
Instruction.Such as, the threshold value of the relative distance of certain gesture operation instruction is more than 5 centimetres, and the threshold value of sensing duration is more than 2 seconds,
The gesture that user is carried out inputs, and its relative distance only has 4 centimetres, and its sensing duration is 3 seconds, then only sensing duration triggers
Its threshold value, relative distance still under threshold value, this gesture input or does not triggers what this gesture operation instructed;User can be worked as
The gesture of input, its relative distance is 6 centimetres, and when its sensing duration is 2.5 seconds, its relative distance and sensing duration all trigger
Respective threshold value, then the input of this gesture can trigger the instruction of this gesture operation.
In step s 11, the gesture input to false triggering has carried out a filtration, improves the effectiveness of gesture input.
And the input of the most effective gesture, can obtain operating effectively instruction, this is also pursuit and the user of intelligent terminal simultaneously
Demand.In another embodiment of the invention, the determination of described operational order is by the way of static data certification
Carry out.User, by the custom according to oneself, is provided with relative distance and the threshold value of sensing duration, and this numerical value is directly in intelligence
Can create on terminal unit complete, directly to the relative distance got and sense duration determining that gesture input when
Data are verified, it is judged that whether it triggers respective threshold value, thus performs the instruction of corresponding gesture operation.
Wherein, described gesture operation instruction includes:
The instruction of described gesture operation is for putting out screen/bright screen instruction, and it causes this intelligent terminal to perform to light/close the control of screen
System operation.
The instruction of described gesture operation is shooting instruction, and it causes this intelligent terminal to obtain picture/regard by its image unit
Frequently.
The instruction of described gesture operation is for starting GPS function command, and it causes this intelligent terminal carry out GPS location and record it
Track.
S13. instruct in response to this gesture operation, perform corresponding control operation.
When intelligent terminal determines the gesture operation instruction of input gesture, will instruct in response to this gesture operation, perform phase
Corresponding control operation.In an embodiment of the present invention, its control operation includes:
When the instruction of described gesture operation is for putting out screen/bright screen instruction, and intelligent terminal puts out screen/bright screen instruction in response to this, performs
Light/close the control operation of screen.
When the instruction of described gesture operation is shooting instruction, and intelligent terminal instructs in response to this shooting, by calling its shooting
Unit or the outside image unit being in communication with connecting carry out obtaining the control operation of picture/video.
When the instruction of described gesture operation is for starting GPS function command, and intelligent terminal, in response to this GPS function command, is carried out
GPS positions and records its track.
Intelligent terminal performs different control operations according to different gesture operation instructions, and that it reflects is exactly user
Demand under different sights.On the one hand, it is in reality situation, there is the possibility of false triggering, at will swing one's arm, it is possible to
Enter within the scope of its relative distance measured, thus cause unnecessary control to operate.On the other hand, time heel distance from,
People is very difficult to judge its exact value from sense organ, carrying out the input being correlated with when, there is the possibility of input error
Property, can not get the result wanted.Such as, the sensing duration triggering shooting instruction needs to reach 3 seconds, and its relative distance needs to reach
6 centimetres;The sensing duration triggering GPS function command needs to reach 4 seconds, and its relative distance needs to reach 7 centimetres;User wants to carry out
The when that GPS controlling operation, the relative distance of the gesture input carried out is 6.5 centimetres, and its sensing duration is but 3.5 seconds, its
That is triggered would is that shooting instruction rather than the GPS function command of its demand.In an embodiment of the present invention, we
Provide prompt facility.It includes step:
Prompt the user with input gesture operation instruction corresponding to gesture;
When do not obtain intended gesture operation instruction, user it may be noted that gesture mistake and be corrected input.
When user carries out gesture input when, intelligent terminal can point out the hands corresponding to its input gesture to user speech
Gesture operational order, allows user differentiate whether its gesture inputted has obtained corresponding result, if can not get the gesture behaviour wanted
Instruct, it is also possible to operational order is modified, complete correct gesture operation instruction.The input gesture distance intelligence of user
Terminal too far, the sensitive time section of mistake, wait nonstandard behavior, all by voice, user can be reminded, allow user input
Correctly, effective gesture.
