The augmented reality system includes a plurality of mobile devices, each of which is operable by an authorized user, includes a private information accessible to the authorized user and has a tangible touch-display screen for showing the private information; and a central processing station electrically connected with each of the plurality of mobile devices, including a public information accessible to all of the authorized users and having a tangible touch-display interface for showing the public information, wherein when the private information included in one of the plurality of mobile devices and accessible to the authorized user is transmitted to the central processing station, it is regarded as the public information and accessible to all of the authorized users. ## Claims ### Claim 1 An augmented reality system for use in an on-site civil engineering construction process, comprising: a central processing station including and processing a public information accessible to all users and having a tangible touch-display interface for showing the public information; a plurality of mobile devices, each of which is electrically connected with the central processing station, is correspondingly operable by an authorized user of all users, includes and processes a private information exclusively accessible to the authorized user and has a tangible touch-display screen for showing the private information and a camera; and a plurality of tangible markers recognizable by the camera on each of the plurality of mobile devices and optionally placed on the tangible touch-display interface, wherein once the private information included in one of the plurality of mobile devices and accessible to the authorized user is transmitted to the central processing station, it is regarded as the public information and accessible to all users, such that all information inputted into the system is classified into the private information and the public information based on the device it stored. ### Claim 2 (depends on 1) The augmented reality system in claim 1, wherein when the authorized user demands on performing a public discussion regarding the public information, the plurality of tangible markers are optionally placed on the tangible touch-display interface by the authorized user on demand to facilitate the discussion process. ### Claim 3 (depends on 1) The augmented reality system in claim 1, wherein each of the plurality of mobile devices is one selected from a group consisting of a smart phone, a tablet computer and a notebook computer. ### Claim 4 (depends on 1) The augmented reality system in claim 1, wherein the central processing station is a building information modeling (BIM) desk. ### Claim 5 (depends on 1) The augmented reality system in claim 1, wherein the private information included in the plurality of mobile devices is exclusively allowed to be modified by the authorized user. ### Claim 6 (depends on 1) The augmented reality system in claim 1, wherein the public information is allowed to be sent to the plurality of mobile devices and is available and accessible to the authorized user on the plurality of mobile devices. ### Claim 7 An augmented reality system for use in an on-site civil engineering construction process, comprising: a central processing station including and processing a public information accessible to all users and having a tangible touch-display interface for showing the public information; and a plurality of mobile devices, each of which is electrically connected with the central processing station, is correspondingly operable by an authorized user of all users, includes and processes a private information exclusively accessible to the authorized user and has a tangible touch-display screen for showing the private information and a camera, wherein once the private information included in one of the plurality of mobile devices and accessible to the authorized user is transmitted to the central processing station, it is regarded as the public information and accessible to all users, such that all information inputted into the system is classified into the private information and the public information based on the device it stored. ### Claim 8 (depends on 7) The augmented reality system in claim 7 further comprising: a plurality of tangible markers recognizable by the camera on each of the plurality of mobile devices and optionally placed on the tangible touch-display interface. ### Claim 9 (depends on 8) The augmented reality system in claim 8, wherein when the authorized user demands on performing a public discussion regarding the public information, the plurality of tangible markers are optionally placed on the tangible touch-display interface by the authorized user on demand to facilitate the discussion process. ### Claim 10 (depends on 7) The augmented reality system in claim 7, wherein each of the plurality of mobile devices is one selected from a group consisting of a smart phone, a tablet computer and a notebook computer. ### Claim 11 (depends on 7) The augmented reality system in claim 7, wherein the central processing station is a building information modeling (BIM) desk. ### Claim 12 (depends on 7) The augmented reality system in claim 7, wherein the private information included in the plurality of mobile devices is exclusively allowed to be modified by the authorized user. ### Claim 13 (depends on 7) The augmented reality system in claim 7, wherein the public information is allowed to be sent to the plurality of mobile devices and is available and accessible to the authorized user on the plurality of mobile devices. ### Claim 14 An augmented reality method for use in an on-site civil engineering construction process, comprising: providing a central processing station including and processing a public information accessible to all users and having a tangible touch-display interface for showing the public information; providing a plurality of mobile devices, each of which is electrically connected with each of the plurality of mobile devices, is correspondingly operable by an authorized user of all users, includes and processes a private information exclusively accessible to the authorized user and has a tangible touch-display screen for showing the private information; and sending the private information to the central processing station by the authorized user for rendering the private information to be regarded as the public information accessible to all users, such that all information inputted into the system is classified into the private information and the public information based on the device it stored. ### Claim 15 (depends on 14) The augmented reality method in claim 14, wherein each of the plurality of mobile devices is one selected from a group consisting of a smart phone, a tablet computer and a notebook computer. ### Claim 16 (depends on 14) The augmented reality method in claim 14, wherein the central processing station is a building information modeling (BIM) desk. ### Claim 17 (depends on 14) The augmented reality method in claim 14, wherein the private information included in the plurality of mobile devices is exclusively allowed to be modified by the authorized user. ### Claim 18 (depends on 14) The augmented reality method in claim 14, wherein the public information is allowed to be sent to the plurality of mobile devices and is available and accessible to the authorized user on the plurality of mobile devices.
