Description
Technical field
The present invention means a kind of projection type virtual keyboard device, and being applicable to needs input data but the electronic product of a large amount of physical buttons can't be installed because of area configuration, perhaps for some environment such as hospital, dust free room of avoiding control of dust, provides splendid solution.
Background technology
Known input about the electronic product data, majority are physical button or the input of hand-written software, as: the input of PDA cooperates a fewer keys, different literals can occur by the different number of times of mobile phone key continuously with hand-written software.These electronic products that can't install more keys because of area configuration have influenced the speed of user's data input, other environment of avoiding control of dust for example: the dust that environment such as hospital, dust free room then produce for the physical keyboard groove also has the trouble in the cleaning.
The restriction of supervising in aforementioned physical button or hand input device is arranged, and this case inventor researchs and solves the solution that is difficult to directly install in electronic product a large amount of keyboards, and a kind of projection type virtual keyboard device is designed in invention.
Summary of the invention
Fundamental purpose of the present invention is to be to provide a kind of projection type virtual keyboard device, and being applicable to needs input data but because of area configuration the electronic product of a large amount of physical buttons can't be installed, and perhaps avoids the environment such as hospital, dust free room of control of dust.
For achieving the above object, a kind of projection type virtual keyboard device of the present invention, it includes CPU computer processing unit, keyboard projecting cell, image signal acquisition unit, morphological feature analytic unit, signal output unit etc., wherein: CPU computer processing unit, being built in electronic product in the system, is the execution and the calculation process of aforementioned each unit of may command; The keyboard projecting cell, be can in be built in electronic product, the dummy keyboard image can be incident upon any body surface, the user can directly touch the dummy keyboard image of projection with input data on the surface of projection; The image signal acquisition unit, system can in be built in electronic product, be to be the CMOS digital code camera, it will be covered by user's hand in the keyboard region of the dummy keyboard image of projection and the image of not crested is taken in and via Frame Grabber picked image changed into signal input CPU computer processing unit; The morphological feature analytic unit utilizes the image identification mode that aforementioned image is analyzed to confirm that aforementioned user is touched the virtual key of dummy keyboard image; The signal output unit, the display screens that the character signal is transferred to electronic product shows the literal that the user imports.
Description of drawings
Fig. 1 is the process flow diagram of the embodiment of the invention.
Fig. 2 is the user mode reference view that is built in electronic product embodiment in the present invention.
Fig. 3 is the user mode reference view that the present invention is external in electronic product embodiment.
Embodiment
As Fig. 1-shown in Figure 2, a kind of projection type virtual keyboard device of the present invention is to include CPU computer processing unit 5, keyboard projecting cell 1, image signal acquisition unit 2, morphological feature analytic unit 3, signal output unit 4 etc., wherein:
CPU computer processing unit 5, be built-in or external (present embodiment is built-in) in personal digital assistant PDA (Personal Digital Assistant) 6, mobile phone or panel computer electronic products such as (Tablet PC), be to be the execution and the calculation process of aforementioned each unit of may command;
Keyboard projecting cell 1, system can built-in or external (present embodiment be built-in) in electronic products such as personal digital assistant PDA6, mobile phone or panel computers, be dummy keyboard image 11 can be incident upon any body surface, the user can directly touch the dummy keyboard image 11 of projection with input data on the surface of projection;
Image signal acquisition unit 2, system can built-in or external (present embodiment be built-in) in personal digital assistant PDA6, electronic product such as mobile phone or panel computer, be to be to can be CMOS (ComplementaryMetal-Oxide Semiconductor) digital code camera or CCD electron micrography machine, will be covered by user's hand in the keyboard region of the dummy keyboard image 11 of projection and the image of not crested is taken in and via Frame Grabber (VIDEO CARD) picked image changed into signal input CPU computer processing unit 5 by CMOS digital code camera or CCD electron micrography machine;
Morphological feature analytic unit 3 utilizes the image identification mode that aforementioned image is analyzed to confirm that aforementioned user is touched the virtual key of dummy keyboard image 11;
Signal output unit 4, the display screens 61 that the character signal is transferred to electronic products such as personal digital assistant PDA6, mobile phone or panel computer shows the literal that the user imports;
According to the above, keyboard projecting cell 1 is incident upon body surface with dummy keyboard image 11, and the user can directly touch its virtual key on the surface of projection, and by the CMOS digital code camera of image acquisition unit 2 or CCD electron micrography machine is covered the virtual key in the keyboard region of the dummy keyboard image 11 of projection by user's finger and the image of not crested is taken in and picked image is changed into signal input CPU computer processing unit 5, again through form wait to levy analytic unit 3 utilize the image identification mode with aforementioned image analyzed with confirm dummy keyboard image 11 the virtual key that touched, the result that will analyze is transferred to personal digital assistant PDA6 with the character signal at last, the display screens 61 of electronic product such as mobile phone or panel computer and the literal of user input is shown.
Moreover, reference is shown in Figure 3 in addition is another embodiment of the present invention figure, its major technology content is identical with previous embodiment, and difference is to be that CPU computer processing unit (not showing among Fig. 3), keyboard projecting cell 1 ' and image acquisition unit 2 ' all are to be external in electronic products such as personal digital assistant PDA6, mobile phone or panel computer.
In sum, projection type virtual keyboard device of the present invention disposes the electronic product that a large amount of physical buttons can't be installed applicable to needing input data but because of area, also applicable to some environment such as hospital, dust free room that need avoid control of dust especially, be really to be the value that has on the industry with the present invention.
