Embodiment
The utility model relates to a kind of hand-written input system, this hand-written input system comprises handwriting pad, embedded software, minitype projection machine, the use that both can link to each other of this system with computing machine, also can off line independently use, minitype projection machine in this system, both can directly link to each other, also can link to each other with computing machine with handwriting pad.When projector projects on the handwriting pad, can directly be incident upon hand-written information on the handwriting pad, the user is just as using touch-screen to operate or write; In the time of on projector lens being turned to curtain or light metope, the user can cast out written contents or computer screen content with handwriting pad, can constitute a small-sized interactive demonstration so again environment is discussed, very flexible, simultaneously, because handwriting pad and minitype projection machine are very light and handy, therefore, native system extremely is convenient to carry.
As shown in Figure 1, hand-written input system of the present utility model comprises handwriting pad 10, connects support 20 and projector 30.Projector 30 is installed in an end that connects support 20, and in the present embodiment, the camera lens of projector is towards handwriting pad 10, and hand-written information projects on the handwriting pad 10.
In the embodiment shown in Figure 2, compared to Figure 1, projector 30 to anticlockwise 90 the degree, camera lens is towards the curtain (or light metope) 35 in left side, hand-written information projects on the curtain (or light metope) 35.
In Fig. 3, hand-written input system of the present utility model combines with computing machine 40 and constitutes a small-sized demo system.In the present embodiment, handwriting pad is provided with shows signal interface socket (not shown), and this shows signal interface socket links to each other with the shows signal output interface of computing machine 40 by cable 42; And the shows signal interface socket on the handwriting pad is by the patchcord (not shown) that links to each other with the shows signal input interface of minitype projection machine.Also be provided with information output interface (not shown) on the handwriting pad, can communicate, hand-written information is sent to computing machine by communication link 41 and computing machine.Know as is known to the person skilled in the art, this communication link 41 can be wireless communication link (for example RF, a bluetooth etc.), also can be wire communication link (for example serial communication data line or USB line etc.).In another embodiment, the shows signal output interface of computing machine 40 is connected directly to the shows signal input interface (not shown) of minitype projection machine by data line 42.In embodiment of the present utility model, the shows signal input interface of minitype projection machine can be one or more in VGA, SVGA, XVGA, DVI and the HDMI interface.
In operating process, hand-written information sends the computing machine that is connected to by handwriting pad.Computing machine is handled the information that handwriting pad spreads out of by application software, after integrating with the computing machine displaying contents, projects on the handwriting pad by the minitype projection machine that links to each other with computing machine again, realizes that it is being seen effect that institute is write.When facing toward the minitype projection machine camera lens on curtain or the light metope, the user can so just can constitute a small-sized demonstration environment is discussed with on the handwriting pad written contents or computer screen content being cast out.
Embodiment except small-sized demo system shown in Figure 3, in another embodiment of the present utility model, be provided with embedded computer in the handwriting pad of hand-written input system, and it is provided with the interface that can link to each other with projector, wherein, information output interface on the handwriting pad is communicated by letter with embedded computer and is linked to each other, and the shows signal output interface of embedded computer links to each other with shows signal input interface on the described minitype projection machine.In the present embodiment, handwriting pad is because design has embedded computer, can not connect computing machine and carry out off-line operation, this handwriting pad design has shows signal output interface (being projector's interface), can directly link to each other with minitype projection machine, therefore, the written contents of handwriting pad can directly cast out by minitype projection machine, forms independently a handwriting input and a demo system.
Fig. 4 A and Fig. 4 B are the synoptic diagram of the utility model hand-written input system packed state.Hand-written input system with the three-section type support bar is an example, shown in Fig. 4 A, connects support 20 and comprises first segment support bar 21, the second joint support bar 22 and the 3rd joint support bar 23.Wherein first end of first segment support bar is connected in the frame 11 of handwriting pad, first end of the 3rd joint support bar 23 is (not shown by rotatable web member, universal joint for example) link to each other with minitype projection machine 30, first end of the second joint support bar 22 and second end rotatably are connected in second end of first segment support bar 21 and the 3rd joint support bar 23 respectively by web member.This web member can make its two joint support bars that connect point-blank, can make two joint support bars vertical mutually again, and can not hang because of the weight of projector.In Fig. 4 A, hand-written input system is a sling N pack, the first segment support bar 21 that connects support 20 is vertical mutually with the second joint support bar 22, and the second joint support bar 22 and the 3rd joint support bar 23 are linked to be a straight-bar, minitype projection machine are abutted against on the lower frame of handwriting pad.
Manner of packing shown in Fig. 4 B and Fig. 4 A difference are: first segment support bar 21 can disassemble from the upper side frame 11 of handwriting pad, and can separate with the second joint support bar 22.
As another kind of embodiment, can also adopt a support bar (for example support bar of curved shape) to replace above-mentioned three-section type support bar to realize connecting support 20.In this case, an end of support bar is connected on handwriting pad frame or the base plate by web member, and the other end connects rotatable web member, and minitype projection machine is fixed on the rotatable web member.
As another selection, also can adopt the two-segment type support bar to substitute above-mentioned three-section type support bar and realize connecting support 20.Wherein, first end of first segment support bar is connected on handwriting pad frame or the base plate, and first end of the second joint support bar links to each other with minitype projection machine by rotatable web member.Second end of first segment support bar rotatably is connected in second end of the second joint support bar by web member.
In addition, know as is known to the person skilled in the art, connect the support that support can also adopt other type, for example can adopt flexible flexible pipe, coiled pipe support etc. for example, any in a word minitype projection machine can being installed on the handwriting pad, and can rotate minitype projection machine and make its camera lens turn to support left and right, upper and lower direction all can use, in addition, minitype projection machine will reach 90 degree at least to the angle of left and right, upper and lower all directions rotation.Certainly also can adopt the support that can make the rotation of minitype projection machine omnidirectional.Like this can be as required the camera lens of minitype projection machine be turned to direction (below) towards handwriting pad, towards the direction (top) of ceiling, towards the left side, right side or other any direction.
In a word, in the technical solution of the utility model, minitype projection machine is combined with handwriting pad, realizes hand-written It is being seen effect that input is write, and can consist of a portable small-sized interactive demonstration system simultaneously. In addition, In handwriting pad, install embedded computer and the interface that can link to each other with projector, then this handwriting pad are set Both can connect machine work with computer, also can not rely on external computer, direct and minitype projection machine Work links to each other.
