A method for a mobile terminal to achieve user interaction by simulating a real scene, it is characterized in that, the method comprising the following steps of: A. using a real scene photo captured by the mobile terminal to form a 3D virtual scene corresponding to the real scene and then formulating a scene task for the 3D virtual scene by the mobile terminal, wherein the scene task is a task which should be performed in the real scene corresponding to the 3D virtual scene; B. uploading information of the 3D virtual scene and information of the scene task by the mobile terminal to a server to obtain a shared link, wherein the shared link is a link for accessing the server so as to obtain the information of the 3D virtual scene and the information of the scene task; C. searching for nearby mobile terminals and transmitting the shared link to the nearby mobile terminals, sending an invitation to the nearby mobile terminals and waiting for participation of the nearby mobile terminals by the mobile terminal; D. if the invitation is received by the nearby mobile terminals, then reading the information of the 3D virtual scene and the information of the scene task stored in the server and uploading by the nearby mobile terminals the corresponding personal information of the nearby mobile terminals via the shared link; and E. changing locations of the user roles in the 3D virtual scene according to positioning information of the mobile terminal, receiving a user operation instruction to perform interaction operations via the user roles, and corresponding to the personal information, recording and saving the interaction operation behaviors by the mobile terminal.
