A mobile terminal comprising: a projector configured to project image information; a capturing unit configured to recognize a writing motion on a paper medium and a writing of a specific symbol in an area selected by the writing motion and a touch path drawn on the paper medium by the writing motion; and a controller configured to: execute a control command for the specific symbol in the selected area if the specific symbol matches a preset symbol, and control the projector to project image information corresponding to a result of the execution of the control command on the area with the written specific symbol; and characterized in that the capturing unit is further configured to: determine a priority of projection of image information corresponding to the selected area based on the recognized touch path; increase the priority of projection of image information as the width of the touch path increases; and if the multiple image information overlaps at least partially with each other, project higher-priority image information on a higher projection level than lower-priority image information. a projector configured to project image information; a capturing unit configured to recognize a writing motion on a paper medium and a writing of a specific symbol in an area selected by the writing motion and a touch path drawn on the paper medium by the writing motion; and a controller configured to: execute a control command for the specific symbol in the selected area if the specific symbol matches a preset symbol, and control the projector to project image information corresponding to a result of the execution of the control command on the area with the written specific symbol; and characterized in that the capturing unit is further configured to: determine a priority of projection of image information corresponding to the selected area based on the recognized touch path; increase the priority of projection of image information as the width of the touch path increases; and if the multiple image information overlaps at least partially with each other, project higher-priority image information on a higher projection level than lower-priority image information. execute a control command for the specific symbol in the selected area if the specific symbol matches a preset symbol, and control the projector to project image information corresponding to a result of the execution of the control command on the area with the written specific symbol; and characterized in that the capturing unit is further configured to: determine a priority of projection of image information corresponding to the selected area based on the recognized touch path; increase the priority of projection of image information as the width of the touch path increases; and if the multiple image information overlaps at least partially with each other, project higher-priority image information on a higher projection level than lower-priority image information. determine a priority of projection of image information corresponding to the selected area based on the recognized touch path; increase the priority of projection of image information as the width of the touch path increases; and if the multiple image information overlaps at least partially with each other, project higher-priority image information on a higher projection level than lower-priority image information.
