Next, when the user changes the location of the mobile communication terminal, the sensing unit 140 generates a location change signal according to the location change of the mobile communication terminal. When the position change signal is input, the controller 180 generates a cursor position change signal of an external terminal according to the position change signal. Next, the controller 180 transmits a cursor position change signal of the external terminal to the notebook 200. Herein, the controller 180 can transmit a cursor position change signal of the external terminal to the external terminal by using one of wired and wireless methods. When the cursor position change signal of the external terminal is input, the notebook computer 200 changes the position of the cursor based on the cursor position change signal of the external terminal and projects it on the external projection surface 400 through the projector 300. do. That is, the cursor 410 is moved based on the change of the position of the mobile communication terminal 100 and displayed on the external projection surface 400. That is, the notebook computer 200 controls the projector 300 to project the cursor 420 onto the external projection surface 400. Next, when the user selects the selection icon 600, the controller 180 generates a selection signal and transmits the selection signal to the notebook 200. The selection signal may be generated through the selection icon 600, but may be generated by various methods such as a dedicated key, a side key, and a user's motion recognition. Then, the notebook 200 selects the hyperlinked data 450 corresponding to the position of the cursor 420 (see FIG. 7B). That is, hyperlinked data is selected. Then, the notebook 200 extracts data linked to the hyperlinked data from a memory (not shown), and projects the data to the external projection surface 400 through the projector 300 (see FIG. 7C). As shown in FIG. 7C, the linked data includes text data 460 and a display window 470.

Accordingly, the user can use the mobile communication terminal with the same function as the laser pointer.

According to the user's selection, the display window 430 and the text data 440 are displayed on the external projection surface 400. In a state where the display window 430 and the text data 440 are displayed on the external projection surface 400, the user enters a business mode through the user input unit 130. Then, the controller 180 displays a reward icon 700 and a forward icon 710 on the display unit 151 (see FIG. 8A). Here, at least one of the pointer icon 500, the selection icon 600, the reward icon 700, and the forward icon 710 may be displayed on the display unit 151. That is, some icons may be displayed or all icons may be displayed. Next, when the user selects the reward icon 700, the controller 180 generates a reward signal and transmits the reward signal to the notebook 200. The reward signal may be generated through the reward icon 700, but may be generated by various methods such as a dedicated key, a side key, and a user's motion recognition. Then, the notebook 200 extracts previous data that was previously projected onto the external projection surface 400 from a memory (not shown), and extracts the extracted previous data through the projector 300 through the external projection surface 400. ) (See FIG. 8B). That is, text data 460 and a display window 470 are displayed on the external projection surface 400. Next, when the user changes the location of the mobile communication terminal, the sensing unit 140 generates a location change signal according to the location change of the mobile communication terminal. When the position change signal is input, the controller 180 generates a cursor position change signal of an external terminal according to the position change signal.
