Mode for the Invention
Certain exemplary embodiments are described in higher detail below with reference to the accompanying drawings.
In the following description, like drawing reference numerals are used for the like elements, even in different drawings. The matters defined in the description, such as detailed construction and elements, are provided to assist in a comprehensive understanding of exemplary embodiments. However, exemplary embodiments can be practiced without those specifically defined matters. Also, well-known functions or constructions are not described in detail since they would obscure the application with unnecessary detail.
FIG. 1 is a schematic view illustrating configuration of a control system according to an exemplary embodiment.
Referring to FIG. 1, a control system 1000 comprises a user terminal 100 and an electronic apparatus 200.
The user terminal receives a user command to manipulate a User Interface (UI) screen provided by the electronic apparatus 200 and transmits it to the electronic apparatus 200.
Specifically, once the user terminal 100 is connected to the electronic apparatus 200, the user terminal 100 may provide a touch mode where a touch manipulation to navigate menu items provided on the UI screen of the electronic apparatus 200 is input.
In addition, when a predetermined touch manipulation is input in the touch mode, the user terminal 100 may transmit information corresponding to the input touch manipulation to the electronic apparatus 200.
Meanwhile, the user terminal 100 may be realized in various forms such as a mobile phone, a notebook computer, a PMP, an MP3, and so on, but is not limited thereto as long as it includes a touch pad.
The electronic apparatus 200 provides a UI screen which can be manipulated in the user terminal 100, and herein the UI screen may include various menu items.
In addition, the electronic apparatus 200 may be connected to the user terminal 100 which provides a touch mode where a touch manipulation to navigate menu items provided in the UI screen is input.
The electronic apparatus 200 may also receive information corresponding to a touch manipulation input in the touch mode of the user terminal 100 and navigate menu items provided on the UI screen according to the received information.
Meanwhile, the electronic apparatus 200 may be realized as a center fascia screen apparatus in a vehicle, but may also be an apparatus providing a UI which can be controlled by a touch manipulation input in the user terminal 100. Herein, the center fascia refers to the front portion of the vehicle interior between the driver seat and the passenger seat where devices such as an audio, an air conditioner, a navigation, etc. are located. The center fascia screen apparatus may be an audio, navigation, and so on.
FIG. 2 is a block diagram illustrating configuration of a user terminal according to an exemplary embodiment.
Referring to FIG. 2, the user terminal 100 comprises a communication unit 110, a display unit 120, and a controller 130.
The communication unit 110 communicates with the external apparatus 200 which provides a UI screen.
In particular, the communication unit 110 performs connection to the external apparatus 200 and then, transmits an event occurring in the display unit 120 which will be explained later to the external apparatus 200.
Herein, the communication unit 110 may be realized as a Bluetooth communication module, a Wi-Fi communication module, and a USB communication module, and so on. Accordingly, the communication unit 110 may perform communication with the electronic apparatus 100 using a notified wired or wireless protocol such as Bluetooth, Wireless Fidelity (Wi-Fi), other USB standard Internet, LAN, Ethernet, TCP/IP, IPX, FireWire, IEEE 1394, iLink, CDMA, TDMA, High Definition Multimedia Interface (HDMI-CEC), Wireless HDMI-CEC, Radio Frequency (RF), and so on.
The display unit 120 may display various information provided by the user terminal 100.
However, when the display unit 120 is connected to the external apparatus 200, the display unit 120 may provide a touch mode where a user touch command to manipulate a UI screen provided by the external apparatus 200 is input.
Herein, the display unit 120 may be realized as a touch screen which forms an interlayer structure with respect to a touch pad. In this case, the display unit 120 may perform not only an output function but also the functions of a user interface which will be explained later. In addition, the touch screen may be configured to detect not only the location and size of a touch input but also the pressure of a touch input.
The controller 130 controls overall operations of the user terminal 100.
In particular, if the controller 130 is connected to the external apparatus 200, the controller may control the display unit 120 to provide a touch mode where a user touch command to manipulate a UI screen provided by the external apparatus 200 is input.
In addition, if a predetermined touch manipulation is input, the controller 130 may control the communication unit 110 to transmit information corresponding to the input touch manipulation to the external apparatus 200.
Herein, the information corresponding to a touch manipulation may be at least one of the number of touch manipulations and the number of touch points which are input at a time.
In this case, the number of touch manipulations may navigate the depth of menu items, and the number of touch points which are input may navigate menu items provided in the same depth.
In addition, when information regarding a UI screen is received from the external apparatus 200, the controller 130 may compare information corresponding to an input manipulation with information regarding the received UI screen and control to transmit information corresponding to the input touch manipulation to the external apparatus based on the comparison result.
Herein, the information regarding the UI screen may be information regarding an item which is currently selected on the menus provided by the UI screen and information regarding the number of sub-menu items of the selected item.
In this case, the controller 130 may compare the number of touch points and the number of sub-menu items of the currently-selected item.
Based on the comparison result, if the number of touch points does not exceed the number of sub-menu items of the currently-selected item on the UI screen, the controller 130 may control to transmit the number of touch points to the external apparatus 200.
Alternatively, if the number of touch points exceeds the number of sub-menu items of the selected item, the controller 130 may control to output an error message.
Meanwhile, various manipulation methods which will be explained later may be used when moving from a sub menu to an upper menu.
According to an exemplary embodiment, a specific touch manipulation may be set as a command to move to an upper step in advance.
For example, it may be predetermined that the touch gesture of sweeping from right to left is a command to move to an upper step. In addition, with reference to information received from the electronic apparatus 200, a command to move to an upper step may be automatically set according to the number of sub-menu items of a currently-highlighted menu item. For example, if there are 3 sub-menu items, a touch manipulation of 4 points which are not used may be set as a command to move to an upper step.
Meanwhile, a touch manipulation to execute a selected item may be set. For example, the gesture of sweeping from top to bottom may be set as a command to execute the corresponding menu item.
In addition, a touch manipulation to move a current highlight key position to an uppermost item (for example, a home menu) may be set. For example, the gesture of swing from bottom to top may be set as a command to execute the corresponding menu item.
However, the above-described touch gestures are only examples, and various other touch gestures may be set as a specific user command. In addition, it is possible to set/change a touch gesture in various ways according to a user setting.
