Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Shown in accompanying drawing 1 and accompanying drawing 2, the object of the invention is to realize many multimedia equipments that distribute in space are carried out to synchronous interaction control, comprise that two or more electronic equipments (can be portable, also can be non-portable set), can be for example one or more in smart mobile phone, panel computer (ipad), intelligent TV set, notebook computer.Along with the development of technology; multimedia equipment in people's daily life is more and more; often can run into the scene that simultaneously need to operate between multiple equipment; the above electronic equipment of Liang Tai in three dimensions and two is undertaken when mutual by identification gesture; every equipment at least needs a sonic generator, three acoustic receivers, or three sonic generators; an acoustic receiver, or the generator of other quantity and receiver.
As shown in Figure 1, before carrying out alternately, first need to determine mutual object-based device, the equipment that sends data need be determined the positional information of receiving equipment, wherein an equipment sends synchronizing signal, after each device synchronization, then send positioning signal, calculate the relative position relation of other each equipment and this equipment.In the effective finding range of equipment time, the sonic generator transmitting coordinate detection signal of equipment, this sound wave is through reflecting back into the acoustic receiver of equipment, each coordinate detection signal is converted into a range information after reception, by the calculating of multiple range informations being obtained to the real-time space coordinate between this multimedia equipment and every other multimedia equipment, and transfer to this multimedia equipment.Because be three-dimensional space, every equipment must possess four or more generator and receiver, for example, and a sonic generator and three acoustic receivers, or the sonic generator of other quantity and acoustic receiver.Calculate sound wave can obtain this equipment and other equipment relative position information from being issued to the time of reception.
In above step, can send pairing coded signal (certain special sound wave) by an equipment, other equipment receive sound wave, receive that the multimedia equipment of the coupling of this pairing coded signal returns to confirmation signal to transmit leg; This special sound wave is the signal of appointing in advance, makes the equipment that receives this sound wave just know that this signal is positioning signal.For example, this location sound wave can have following characteristic: certain specific frequency or amplitude, or each number of cycles sending is specific, or each time interval sending is specific etc.Its two, this sonic energy signal suitably increases, to increase the distance of sonic transmissions.Its three, send this sound wave time short, this time is: the equipment of transmitted signal sends after this sound wave, and receiving equipment receives this sound wave, after having calculated, result is sent it back send location sound wave equipment.Such as, two equipment are at a distance of 2 meters, send sound wave to reception sound wave time be 5.88ms, after calculating completes, the equipment of reception sound wave can send to the equipment that sends location sound wave by signals such as bluetooth, wifi, NFC, the whole position fixing process time very, the energy of this short time increases, and power consumption can not be affected.After finish location, each equipment enters gesture identification state.
As shown in Figure 2, in the time of action recognition, every multimedia equipment produces action detectable signal by positioning signal transmitter unit respectively, reflects by the predefined interactive instruction of identification after the reception of positioning signal receiving element by move mode and the moving direction of action object.When multiple devices are identified a certain gesture simultaneously, acoustic signals multiple reflections and reception, deal with very complicatedly, and this patent provides improving one's methods of gesture identification in a kind of three dimensions, each equipment is only identified respectively the gesture of this TV station equipment top, and need not identify the gesture of other equipment tops.In illustrated scene, two hands can operate simultaneously before two equipment, or many people are operation simultaneously before multiple devices, this mode can improve interactive speed greatly, these device just processing receive strong sound wave signal, the signal that the acoustic signals that other equipment send receives after reflecting by hand or barrier is undesired signal, filter out after this undesired signal with wave filter, judge the gesture mode that this acoustic signals is corresponding, equipment carries out corresponding data transmission and processing according to these gestures.In Fig. 2,5 and 6 is acoustic receiver and the sonic generator of equipment 3, and 7 and 8 is acoustic receiver and the sonic generator of equipment 4.Hand 1 is nearest from equipment 3, and 3 of equipment need the action of identification hand 1.Hand 2 is nearest from equipment 4, and 4 of equipment need the action of identification hand 2.Equipment 4 receives and receives through receiving and distributing 2 signals that are reflected back much smallerly through receiving and distributing the relative equipment 4 of 1 acoustic signals being reflected back, and can be used as noise signal and filters out therefore equipment 4 receives through receiving and distributing 1 signal being reflected back.In like manner receive through receiving and distributing 2 acoustic signals that are reflected back than much smaller through receiving and distributing 1 acoustic signals being reflected back for equipment 3, therefore can be used as noise filtering and fall through receiving and distributing 2 signals that are reflected back.When equipment is surveyed action, data processing as shown in Figure 3, when the barriers such as hand move, sonic generator transmitting sound wave on equipment, receive sound wave to acoustic receiver, the barriers such as hand also can change to the distance between these acoustic receivers, more this variation can be learnt the move mode of the barriers such as hand, calculate the distance of action object with respect to each multimedia equipment, the represented interactive instruction of multimedia equipment identification maneuver object that distance is minimum, application software in equipment has a gesture identification storehouse, gesture to identification and equipment carry out corresponding operation an agreement, the mode in the gesture storehouse of the application software of this move mode and equipment is mated, if can mate, equipment is carried out the corresponding operation under this gesture.
When electronic equipment is identified after certain certain gestures, each multimedia equipment is carried out corresponding action according to the interactive instruction receiving separately respectively, and gesture is based on certain agreement, a kind of mode cooperating with the interactive interface of equipment.By identifying the gesture of some agreement, the equipment that sends data can become the equipment that receives data, and the equipment that receives data also can become the equipment that sends data, and the exchanges data between equipment is very flexible.When many equipment is mutual, one of them equipment is to other equipment sending datas and instruction, other equipment receiving data or instruction, and the quantity that receives the equipment of data or instruction can be one or more.Such as, when game, after an a certain gesture of recognition of devices, equipment is carried out corresponding operation, the next gesture to be identified such as follows, and other equipment also carry out gesture identification simultaneously, and carry out corresponding operation.This just requires the application software in equipment will appoint in advance, when many equipment is mutual, identifies which kind of gesture motion equipment and carries out which kind of operation.In the time that a multimedia equipment receives data and sends instruction, another multimedia equipment and receive data receiver instruction, between this is to multimedia equipment, carry out corresponding data transmission action.For example, select to need the file of transmission, choose after this file, hand or input object are carried out a specific action, as " pick up ", move to the top of equipment 2, carry out again a specific action, as " put down ", mode of motion and the direction of equipment 2 these actions of identification, the position of location hand or certain input object, starts to transmit file.Data transmission between equipment 1 and equipment 2 can be passed through wifi, bluetooth, and mobile network, the modes such as NFC, complete certain specific interactive action between two or multiple electronic equipment thus.
The present invention is based on and between the three-dimensional two or more electronic equipments of being in of sound wave gesture identification, carry out alternately,, send one and specially cut the location sound wave that energy is larger when the location.When equipment enters the gesture identification stage alternately, each equipment is only identified the gesture of this equipment top, without the gesture of other equipment of identification.By identifying the gesture of some agreement, the equipment that sends data can become the equipment that receives data, and the equipment that receives data also can become the equipment that sends data.In this patent, the each self-identifying of equipment is from the nearest gesture of the machine, without the gesture on other equipment is analyzed.If distance is closer between equipment, in common identification range, so, acoustic signals has power, the acoustic signals being reflected back from the nearest gesture of the machine is stronger, the acoustic signals that the gesture from the machine away from is reflected back a little less than, in each equipment acoustic signals processing procedure, weak signal will be filtered, only the stronger signal of identification.Like this, when each recognition of devices gesture, processing signals is relatively easy, and accuracy rate is high, and real-time is stronger, and interactive speed is faster.
It is to be noted in addition, coordinate detection signal in above embodiment adopts voice signal or ultrasonic signal, this is because at present a lot of electronic equipments have microphone assembly and loudspeaker assembly, microphone assembly can be used as acoustic receiver, and loudspeaker assembly can be used as sonic generator, in electronic apparatus, do not need to increase extra components and parts, do not affect device hardware layout, can increase the reliability of product, power consumption is very low, flying power impact on battery is very little, cost is low, technical difficulty is not high, can greatly improve the competitive power of electronic product at colleague's product, and resolution is high, feasibility is very high.It is pointed out that locator meams in the present invention also can calculate as signals such as optical signalling, electromagnetic wave signal, voice signals by other.
Above embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art understand content of the present invention and implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence does according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
