Portable device and control method thereof

A portable device for transmitting a user input, the portable device comprising:

• a sensor unit configured to detect the user input;
• a communications unit configured to communicate with an external device;
• and
• a controller configured to perform actions including:
• detecting a navigating input in a navigation mode for controlling the external device which is connected with the portable device,
• wherein the external device displays a displayable content which includes an external device input box, and
• wherein the navigating input is for navigating the displayable content;
• transmitting a control signal corresponding to the detected navigating input to the external device;
• displaying an indicator which indicates a capability of mode switching from the navigation mode to a user input mode;
• initiating the user input mode by displaying a portable device input box extracted from a displayed area of the displayable content when a mode switching input is detected,
• wherein initiating the user input mode comprises determining a priority of the external device input box, and displaying the portable device input box corresponding to the determined priority of the external device input box, wherein the priority depends on a position of the external device input box in the displayable content;
• and
• transmitting the user input which is inputted in the portable device input box,
• wherein, when the external device input box is moved from the displayed area to a non-displayed area of the displayable content, the portable device input box is maintained on the portable device.
