Handwriting input position sensible element on this person's handwriting harvester has wave transmitting device and receiving trap; Its medium wave emission device has the opposite opening of both direction, respectively facing to two rightabout input medias, can be used to import the ripple of person's handwriting collection location to two opposite direction emissions by these two openings; The reflection wave that wave receiving device identification is beamed back from input pen comes from the input on the input media on which direction on earth.Wherein wave receiving device is the opposite ripple sensing device of both direction, has one between the two to the opaque baffle plate of induction ripple; The reflection wave of beaming back from input pen is transfused to the rightabout wave receiving device reception of medium owing to can not cross baffle plate, can only be received with the identical wave receiving device of input direction, on two kinds of opposite input medias of direction, which kind of is carried out handwriting input on earth above thereby identify the user.
The handwriting input person's handwriting harvester designed according to this method, comprise handwriting input location sensitive wave transmitting device and receiving trap and some support circuits, the reaction of induction ripple is determined the position of writing pencil according to writing pencil, continuously record is carried out in the variation of writing pencil position, thereby support hand-written input system to finish identification handwriting.Its medium wave emission device has the opposite opening of both direction, respectively facing to two rightabout input medias, can be used to import the ripple of person's handwriting collection location to two opposite direction emissions by these two openings; The reflection wave that wave receiving device identification is beamed back from input pen comes from the input on the input media on which direction on earth.Especially, the wave transmitting device shape can highly be higher than two kinds of the highest parts in input media position for cylindrical.Wave receiving device is the opposite ripple sensing device of both direction, has one between the two to the opaque baffle plate of induction ripple; The reflection wave of beaming back from input pen is transfused to the rightabout wave receiving device reception of medium owing to can not cross baffle plate, can only be received with the identical wave receiving device of input direction, on two kinds of opposite input medias of direction, which kind of is carried out handwriting input on earth above thereby identify the user.
For the ripple induction, wave transmitting device can be launched ultrasound wave, receives the infrared ray that feedback is launched in the back by writing pencil, informs wave receiving device, thus the position of calculating and orienting writing pencil.If adopt infrared ray as induction feedback ripple, the baffle plate between the ripple sensing device that the wave receiving device both direction is opposite so needs opaque to infrared ray.
Advantage of the present invention and good effect are:
Adopt this method and apparatus to carry out handwriting input, write in can be under mobile status hand held the display screen of mobile device (for example PDA); Taking minutes or relative fixed occasion when writing, available pen is write on paper.Dual mode can be selected according to the needs of the different occasions of user.
Except can under different occasions, write facilitate, this method and apparatus can also be saved the cost of the mobile device that is used for handwriting input.For example, just can save and be equipped with a touch-screen, and the present cost of touch-screen to be higher than the cost of above-mentioned handwriting collecting device for PDA.Carry out and can also adopt with a kind of input pen for writing of two kinds of interfaces.
Description of drawings:
Fig. 1 is twocouese handwriting input identification and device synoptic diagram thereof.
Among the figure, 1-PDA, the 2-wave transmitting device, the 3-wave receiving device, the 4-writing pencil,
The 5-infrared transmitter, 6-baffle plate, 7-paper.
Be described further below in conjunction with embodiment:
Referring to Fig. 1 twocouese handwriting input identification and device synoptic diagram thereof, we illustrate how to carry out two kinds of handwriting inputs on the different medium.For example wish to carry out writing on the paper 7, and the handwriting input on the PDA1 is carried out in the left side on this device right side.In addition, write, so just paper is fixed on the right side of handwriting collecting device if want on paper, to carry out the right hand; If left hand is write, then paper is fixed on the device left side; This is set in recognition device accordingly.Equally, on equipment such as PDA, importing, just PDA is placed a side of harvester according to user situation.
For example wave transmitting device 2 adopts ultrasonic transducer as wave transmitting device.Transducer is cylindrical, and its top is higher than the display screen of paper and PDA1.This top and arranged on left and right sides leaves the ultrasound wave mouth.
For example wave receiving device 3 adopts infrared receiver.If write on the paper on the right, the infrared light signal of infrared transmitter 5 emissions of writing pencil 4 will be along rectilinear propagation so.Wave receiving device 3 will receive the infrared signal of writing pencil 4 emissions towards the one side of paper.And because of the effect of baffle plate 6, the one side of paper dorsad, promptly the wave receiving device 3 towards PDA1 display screen one side just can not receive this infrared signal.Final computer Recognition part just can judge the user be write on the paper on the right or the display screen of on the left side PDA1 on carry out write.
