Abstract
The invention discloses an implementation method of a virtual mobile phone keyboard. The method comprises the following steps of: creating a projection keyboard template, and projecting the projection keyboard template to a surface of a certain adjacent interface, wherein the projection keyboard template can be generated by a laser diode of a projection component; illuminating a light source of the diode through a high-efficiency holographic optical element which is specially designed to generate an accurate QWERTY keyboard display region; and projecting an invisible plane at a place which is higher than a projection surface by a few millimeters. The method has the advantages that: the defects of smaller mobile phone key region of a QWERTY keyboard and difficulty in operation are overcome; a mobile phone keyboard is projected to a certain medium interface by optical projection; the operation coordinates of a projection keyboard by a user are positioned by an optical sensor; and an image is fed back to a processor and subjected to impact analysis processing to obtain an accurate key value, so that an optical projection keyboard function of a mobile phone is realized.
Description
Technical field
Design of electronic devices of the present invention field relates in particular to a kind of implementation of virtual mobile phone keyboard.Through optical projection cell phone keyboard is projected on certain medium interface; Through optical sensor the user is positioned projected keyboard operation coordinate; And feed back to processor and carry out impact analysis and handle, obtain accurately button value, realize mobile phone optical projection keypad function.
Background technology
Present stage, full-scale qwerty keyboard mobile phone application is more and more wider, but common because portable characteristics can't with size do very big, so on the market qwerty keyboard cell phone keyboard button also compares lessly at present, the user operates very inconvenient.
The mobile phone projection keyboard through with keyboard template through optical projection to a certain medium interface, the user carries out button operation in the projected keyboard zone, thus it is portable and import problem easily to solve the qwerty keyboard mobile phone.
Summary of the invention
To the deficiency of prior art, goal of the invention of the present invention provides a kind of implementation of virtual mobile phone keyboard.
Goal of the invention of the present invention realizes through following technical scheme:
A kind of implementation of virtual mobile phone keyboard; Projected keyboard template of described establishment earlier; The projected keyboard template is projected to the surface of a certain adjacent interfaces; This module can be produced by a projection components and parts laser diode, and the light source of diode is passed through the high-efficiency holographic optics original paper illumination of particular design, produces an accurate qwerty keyboard viewing area.It above projection surface several millimeters locate the plane that projection goes out a stealth.
Described user pushes button and can utilize little lighting module location; This module also can produce the sightless low-light of human eye by laser instrument; This light is at several millimeters places of projection surface, and when the user touched the key position on the interface surface, the plane on this zone key limit will reflect light and turn back to the monitoring device; When the optical plane that promptly produces whenever the low-light module is received disturbance, promptly there is key-press event to take place.
The button mapping process is following: user's finger can be received by imageing sensor after touching low-light sensing plane institute laser light reflected, and reflexes to the CMOS image sensor in the sensor assembly.In case imageing sensor detects reflector laser, sensor will be caught the image of projected keyboard.The image that promptly captures is processed analysis, confirming in the qwerty keyboard pattern which part is occupied or still visible, thereby infers the user's finger position, therefore, just can confirm that also actual thump moves, and output to corresponding apparatus.Process nuclear can be followed the tracks of repeatedly reflection synchronously, therefore can handle multiple button and overlapping cursor control input simultaneously.
The described qwerty keyboard of having realized projects on a certain medium interface; The user is through the operation in the projected keyboard imaging; Thereby reflector laser is reflexed to image sensor; Through the graphical analysis of image sensor, can know that view field's respective keys is pressed, realize keyboard operation function to mobile phone interface.
Described dummy keyboard refers to does not have physical keyboard, and the mode that goes out a dummy keyboard through optical projection realizes.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Label declaration among the figure
The stealthy plane of 1-keyboard area 2-3-image sensor
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1; Keyboard area 1 goes out via the laser diode projection; The projected keyboard template is projected to the surface of a certain adjacent interfaces; This module specifically can be produced by a projection components and parts laser diode, and the light source of diode is passed through the high-efficiency holographic optics original paper illumination of particular design, produces an accurate qwerty keyboard viewing area.It above projection surface several millimeters locate the plane that projection goes out a stealth; Stealthy plane 2 is that the low-light module projects, and when button operation was carried out in the projected keyboard zone, the low-light projection was triggered the relevant detection device by disturbance, thereby informs that processor has corresponding key-press event to take place; User's finger can be received by imageing sensor after touching low-light sensing plane institute laser light reflected, and reflexes to the CMOS image sensor 3 in the sensor assembly.In case imageing sensor detects reflector laser, sensor will be caught the image of projected keyboard, when button, be used for dummy keyboard key position image is captured, and carry out analyzing and processing thereby pass to processor.
