Hereinafter, an exemplary embodiment of a method of transmitting UI data and displaying a GUI will be described with reference to FIGS. 30 and 31.

FIG. 30 is a flowchart illustrating a method in which the main unit receives UI data through wired communication and displays a GUI.

First, a first communication port and a second communication port are connected by connecting the main unit and the fixing unit (operation S10), and the first wired communication unit and the second wired communication unit determine whether the first wired communication unit of the main unit has been connected to the second wired communication unit of the data unit through ports (operation S20).

When the first communication port is not connected to the second communication port, the wearable device ends the UI data transfer and the UI state transition.

In contrast, when it is determined that the first communication port is connected to the second communication port, the first wired communication unit and the second wired communication unit transmit at least one of pieces of UI data stored in the second memory to the first memory (operation S30).

Also, the control unit checks whether the transmitted UI data is stored in the first memory (operation S40).

When the transmitted UI data is stored in the first memory, the main unit causes the UI state to transition using the UI data stored in the first memory (operation S60).

In contrast, when the transmitted UI data is not stored in the first memory, the first memory stores the transmitted UI data (operation S50) and the main unit causes the UI state to transition using the UI data stored in the first memory (operation S60).

FIG. 31 is a flowchart illustrating a method in which the main unit receives UI data through wireless communication and displays a GUI.

First, the first wireless communication unit and the second wireless communication unit determine whether the first wireless communication unit of the main unit and the second wireless communication unit of the data unit are connected through a radio session (operation S110).

When it is determined that the first wireless communication unit and the second wireless communication unit are not connected through the radio session, the wearable device ends the UI data transfer and the UI state transition.

In contrast, when it is determined that the first wireless communication unit and the second wireless communication unit are connected through the radio session, the first wireless communication unit and the second wireless communication unit transmit at least one of pieces of UI data to the first memory (operation S120).

Then, the control unit checks whether the transmitted UI data is stored in the first memory (operation S130).

When the transmitted UI data is stored in the first memory, the main unit causes the UI state to transition using the UI data stored in the first memory (operation S150).

In contrast, when the transmitted UI data is not stored in the first memory, the first memory stores the transmitted UI data (operation S140) and the main unit causes the UI state to transition using the UI data stored in the first memory (operation S150).

Hereinafter, exemplary embodiments of a method of determining whether the data unit currently connected to the main unit is a previously connected data unit or a newly connected data unit and performing authentication when the data unit is the newly connected data unit will be described with reference to FIGS. 32 and 33.

Then, the main unit may determine whether a user signal indicating that the existing data unit has currently been connected to the main unit has been received (operation S220).

When the main unit determines that the user signal indicating that the existing data unit has currently been connected to the main unit has been received, the main unit may immediately end the process without performing an authentication procedure and the UI data transmission process.

In contrast, when the main unit determines that the user signal indicating that the existing data unit has currently been connected to the main unit has not been received, the main unit may determine whether the user signal indicating that the new data unit has currently been connected to the main unit has been received (operation S230).

When the main unit determines that the user signal indicating that the new data unit has currently been connected to the main unit has not been received, the main unit may perform operations S210 to S230 again.

In contrast, when the main unit determines that the user signal indicating that the new data unit has currently been connected to the main unit has been received, the main unit may provide a request message for inputting a pin number of the currently connected data unit to the touch screen (operation S240).

Then, when the main unit receives the pin number input from the user (operation S250), the authentication procedure may end. Thereafter, the main unit may receive and store UI data stored in the data unit (operation S260).

FIG. 33 is a flowchart illustrating a method of automatically detecting and determining whether the data unit is the previously connected data unit or the newly connected data unit and connecting the main unit to the data unit.

First, the main unit may detect that the data unit has been connected (operation S310).

Then, the main unit may determine whether the currently connected data unit is the previously connected data unit (operation S320).

When the main unit may determine that the currently connected data unit is the previously connected data unit, the main unit may end the process without performing an authentication procedure and the UI data transmission process.

In contrast, when the main unit determines that the existing data unit has not been connected to the main unit, the main unit may provide a request message for inputting a pin number of the currently connected data unit to the touch screen (operation S330).

Then, when the main unit receives the pin number input from the user (operation S340), the authentication procedure may end. Thereafter, the main unit may receive and store UI data stored in the data unit (operation S350).
