     The invention provides a practical glasses waistband-type computer device for introducing technology and productivity calculation into the mobile Internet, which allows the commonly used PC computer operating system software to enter the mobile field immediately without any modification, and makes up for the shortcomings of the key technologies of mobile man-machine interaction that have existed for many years; the glasses waistband-type computer device according to the invention can collect the scientific and technological productivity ecological resources of traditional PC computers and the entertainment service ecological resources of smartphones in one machine, can complete the work that a common laptop computer or PC computer or wall-mounted TV can complete in one machine, can provide a new mobile man-machine interaction method and a new device thereof with new technologies of VR and AR, and can also be used as a new mobile platform for robotics, cloud computing and 5G technology, which is a multi-functional wearable computer with various functions commonly used in today&#39;s computers. 
     Embodiment 2 
     When all areas of the electrically controlled dimming screen are controlled to a transparent state, the optical synthesizer lens superimposes the projected image with adjustable size of the content area from the microdisplay on the image formed from the real environment field of view through the electrically controlled dimming screen, to form the display image output of AR; the AR display image output of the glasses display is cooperated with the folding keyboards on the waistband and the man-machine interaction input device of the mouse, together with the smartphone, so that the invention has the purpose of using AR technology in a high-efficiency and high-skilled man-machine interaction mode of existing technology and productivity under mobile conditions, which improves the ability to use AR technology and expands the scope of application of the technology; 
     when all areas of the electrically controlled dimming screen are controlled to an opaque state, there is only the display image output of the VR formed by the VR projection with the content area of the microdisplay adjustable in size on the optical synthesizer lens; the VR display image output of the glasses display is cooperated with the folding keyboards on the waistband and the man-machine interaction input device of the mouse, together with the smartphone, so that the invention has the purpose of using VR technology in a high-efficiency and high-skilled man-machine interaction mode of existing technology and productivity under mobile conditions, which improves the ability to use VR technology and expands the scope of application of the technology; 
     when the local area of the electrically controlled dimming screen matches the adjusted display shape and size from the projected content area of the microdisplay and is controlled to an opaque state, and the remaining areas around the local area are controlled to a transparent state, the optical synthesizer lens superimposes the projected image from the microdisplay on the opaque image of the electrically controlled dimming screen to form a superimposed image, and the superimposed image is combined with the surrounding real image formed by the real environment through the electrically controlled dimming screen in the user&#39;s field of vision, so that the user&#39;s field of view has an image and display area similar to a PC display screen; the image display output of the glasses display similar to the PC display screen is cooperated with the folding keyboards on the waistband and the man-machine interaction input device of the mouse, together with the smartphone, so that the invention has the purpose of using similar existing notebook computers, desktop PC computers, and wall-mounted large-screen computers under mobile conditions, which improves the ability to use the existing computer technology and expands the scope of application of the technology. 
     Unless otherwise stated in any of the technical solutions disclosed by the invention, if it discloses a numerical range, then the disclosed numerical range is the preferred numerical range, and any person skilled in the art should understand: the preferred numerical range is only a numerical value with obvious or representative technical effect among the many feasible numerical values. Since the numerical values are too numerous to be exhaustive, only some numerical values are disclosed in the invention to illustrate the technical solutions of the invention, and the above numerical values shall not constitute a limitation on the protection scope of the invention. 
     If the invention discloses or involves parts or structures that are fixedly connected to each other, then, unless otherwise stated, fixed connection can be understood as: detachable fixed connection (for example, by bolts or screws), and can also be understood as: non-detachable fixed connection (such as riveting and welding); of course, the mutual fixed connection can also be replaced (except that it is obviously impossible to use integral forming process) by an integrated structure (for example, integrally formed by a casting process).
