The keyboard projection module 22 is built in the casing 21 and can output keyboard projection signals. Each keyboard projection module 22 outputs different keyboard projection signals respectively, and the balls 60 are transmitted to the keyboard projections. Device 10. In this embodiment, four keyboard projection contacts 2112 and four keyboard projection modules 22 are included, which can respectively project a mobile phone keyboard, a computer keyboard, a music keyboard and a game keyboard. The processing device 23 is built in the casing 21 and controls the execution and arithmetic processing of the modules. The image signal capturing module 24 is built in the casing 21, and further includes an image capturing lens 241 disposed on the casing 21, and the image signal capturing module 24 is configured to The image captured by the user's hand and the unmasked image in the keyboard image area projected by the keyboard projection device 10 are taken in and transmitted to the processing device 23. In this embodiment, the image signal capturing module 24 is a CMOS digital camera or a CCD electron microscope camera. The morphological feature analysis module 25 analyzes and confirms the image taken by the image signal capturing module 24 by using the image recognition method, and recognizes the virtual button touched by the user. The signal output module 26 is configured to output the recognized button character signal and display it by the mobile phone 1.

When the mobile phone 1 is used, the keyboard projection device 10 projects a virtual keyboard image onto the surface of the object, and the user can directly touch the virtual button on the surface of the projection, and the keyboard is captured by the image signal capturing module 24. The image blocked by the user's hand and unmasked in the image area is taken in and input to the processing device 23, and the button for identifying the touch is analyzed by the morphological feature analysis module 25, and output by the signal output module 26. Rotating the keyboard projection device 10, the rotating shaft 30 drives the balls 60 to roll, so that the balls 60 can respectively contact different keyboard projection contacts 2112, and the keyboard projection module 23 projects the projection signals by the balls 60. It is transmitted in the keyboard projection device 10 to realize the projection of the virtual keyboard. By rotating the keyboard projection device 10, different virtual keyboards can be projected, thereby realizing the conversion of different virtual keyboards.

The mobile phone provided by the invention has a keyboard projection device and a host computer, and can rotate different keyboards by rotating the keyboard projection device, so that the conversion between various virtual keyboards can be realized simply and conveniently.

In addition, those skilled in the art can make other changes in the spirit of the present invention. Of course, the changes made in accordance with the spirit of the present invention should be included in the scope of the present invention.
