Portable according to the invention Between terminals  Data transfer method

3 is a flowchart illustrating a data transmission method between portable terminals according to the present invention. When the data transmission method starts, first, the transmitting side portable terminal recognizes the receiving side portable terminal (S310). When recognition of the receiving portable terminal is completed, the transmitting portable terminal waits until a predetermined pattern of motion is input. At this time, the standby time is set within a predetermined time (for example, 5 seconds), and when the motion of a predetermined pattern is not input during that time, the data transmission is canceled. Thereafter, when the user shakes the transmitting side portable terminal in a predetermined pattern, the motion recognition module included in the transmitting side portable terminal recognizes the motion of the predetermined pattern (S320). When the motion of the predetermined pattern is recognized by the motion recognition module, the transmitting portable terminal transmits data to the receiving portable terminal using communication modules included in both portable terminals (S330).

4 is a flowchart specifically illustrating an operation S310 of recognizing a receiving side portable terminal by a transmitting side portable terminal. As shown in FIG. 4, first, the receiving side portable terminal displays a marker including information for recognizing the self on its display (S311). For example, the marker may be a barcode including information for recognizing the portable terminal of the receiver. Thereafter, the user photographs a marker displayed on the receiving portable terminal by using a camera included in the transmitting portable terminal. Then, the transmitting portable terminal recognizes and decodes the photographed marker to recognize the wireless communication address of the receiving portable terminal (S322). The wireless communication address of the receiver portable terminal means predetermined information that can identify the receiver portable terminal according to the radio communication method between the transceiver portable terminals. For example, when performing communication using a wireless LAN between a transmitting and receiving mobile terminal, the wireless communication address of the receiving mobile terminal may be a MAC address.

Fig. 5 is a diagram showing an example of motion of a predetermined pattern for starting data transmission of the transmitting-side portable terminal. The motion of a predetermined pattern may be arbitrarily defined and used in the practice of the present invention. For example, the motion of the predetermined pattern is centered on a point on an extension line of the vertical axis of the terminal at a position where the transmitting terminal recognizes the other terminal. It can be defined as a pattern moving back and forth within a predetermined predetermined angle (for example 45 degrees). This operation is defined as an operation of breaking a terminal. The rotation angle may be arbitrarily defined within a range of 360 degrees. In order to prevent malfunction, it is desirable to define within 45 degrees. In FIG. 5, when the portable terminal moves from the position indicated by the reference numeral 501 to the position indicated by the reference numeral 502 and returns to the position indicated by the reference numeral 501, it is recognized that a predetermined pattern of motion is performed. The vertical axis of the portable terminal after the line indicated by the reference A indicates the vertical axis of the portable terminal at the initial position, and the line indicated by the reference B rotates about one point B on the extension line of the vertical axis A. Indicates. When the angle formed by the line A and the line C with respect to the point B is within a predetermined angle (for example, 45 degrees), the portable terminal is regarded as a reciprocating movement pattern, i. In FIG. 5, the longitudinal axis of the portable terminal is illustrated as a vertical axis, but the vertical axis may mean any one axis penetrating the center of the portable terminal regardless of the length, width, or thickness of the portable terminal. In addition, the rotation direction may be defined in relation to the face direction of the portable terminal or may be defined irrespective of the direction of rotation. Also, the reciprocating pattern does not mean that the portable terminal must return correctly to the initial position 501. After moving from the initial position 501 to the next position 502, the rotor is moved in a pattern just by repeating the movement several times in the direction of the initial position 501 again. Alternatively, it may be recognized that a predetermined motion is taken when returning to within a predetermined error range (for example, 30%) from the initial position.

In addition, 'tilting' a portable terminal as a water bottle may be defined as a predetermined pattern of motion. In this case, the 'tilting' operation may be defined as moving a portable terminal in a horizontal state in a vertical state in space.

Reciprocating rotation, 'burping' operation, 'tilting' operation, etc. can all be detected using known sensing means such as position movement sensor, acceleration sensor, gyro sensor included in the portable terminal.

On the other hand, when acting in an operation other than the designated pattern, it is recognized as canceling data transmission. Therefore, if the user wants to cancel the data transmission even after recognizing the portable terminal in order to transmit the data, the user simply takes the action of lowering the terminal device. Cancel.

FIG. 6 is a diagram illustrating an interface appearing on a display of both portable terminals when data transmission between the transmitting and receiving portable terminals occurs. While data is being transmitted from the transmitting portable terminal 610 to the receiving portable terminal 620, the display 611 of the transmitting portable terminal 610 disappears from the display 611 area and disappears. Appears to be displayed. On the other hand, the display 621 of the mobile terminal 620 on the receiving side displays an image of an icon 622 coming into the display 621 area. In this case, as long as the icon 612 disappears from the display 611 of the portable terminal 610 of the transmitting side, the icons 622 appear on the display 621 of the portable terminal 620 of the receiving side. The display works in sync.

Operation of sending terminal

Hereinafter, specific operations of the transmitting portable terminal and the receiving portable terminal will be described. 7 is a flowchart specifically showing an operation of a transmitting-side portable terminal.

First, the user of the portable terminal of the transmitting side selects data to be transmitted, such as a photo, a phone book, a digital business card, by operating the terminal (S701). In this case, the user may select a plurality of data in some cases. When the user who finishes the file selection presses the button for file transfer (S702), the camera operates to recognize the marker of the receiving portable terminal (S703), and the marker recognition program operates to draw a marker from the image image input through the camera. Recognize and decrypt to obtain communication information with the receiving portable terminal (S704). If the marker recognition and decryption operation is successfully performed (S705), the communication with the receiving portable terminal is established and initialized using the obtained communication information (S706). When the initialization is complete, the user may be informed that the communication is ready by using the LED or sound. Thereafter, when the user takes a predetermined motion for file transmission, such as an operation of turning on the transmitting portable terminal, the transmitting portable terminal recognizes the motion and starts data transmission (S707). Then, the previously selected data is transmitted to the receiving side portable terminal through a wireless communication technology such as Bluetooth or WLAN (S708). When the transmission is completed, the transmission result is output to the user and is displayed (S709).

Operation of the receiving terminal

8 is a flowchart specifically illustrating an operation of a receiving side portable terminal. First, the standby screen is output to the receiving terminal (S801). The user selects a pre-mapped button or menu in the standby screen state to receive data. If it is determined that the button or the menu is pressed (S802), a marker having a MAC address and pin number information for wireless communication such as Bluetooth communication is output (S803) and the portable terminal is ready to receive data. Enter (S804). If reception is started within a predetermined time after entering the reception ready state (S805), the marker disappears from the display (S806). After a predetermined time elapses without receiving data after entering the reception ready state, the display returns to the standby screen state (S805). Instead of receiving the file as a whole, the file is continuously received at a portion of the file (S806), and only a portion of the icon representing the file is displayed (S807). The icon corresponding to the received file is displayed in synchronization with the display of the transmitter. When reception of the entire data is completed (S808), the entire data information is displayed (S809).
