1 is a configuration diagram of a user interface device according to a first embodiment of the present invention. 2 is a view for explaining a knob operation in the user interface device according to the first embodiment of the present invention. 3 is a view for explaining another example of the knob operation in the user interface device according to the first embodiment of the present invention. 4 is a view for explaining the operation direction of the knob in the user interface device according to the first embodiment of the present invention.

 As shown in FIG. 1, the user interface device 1 is provided with a knob 11 and a display unit 12 on one side of the main body 10. The knob 11 may be provided near the display unit 12.

The knob 11 is provided in the main body 10 so as to be pressed by a user.

The knob 11 is provided to enable multi-stage pressing (for example, 2, 3, 4, etc.) so that the pressed degree of the knob 11 can be changed by the user's pressing operation. The knob 11 may be provided to vary the depth of the knob 11 according to the user's pressing degree. At this time, the recessed depth of the knob 11 refers to a value corresponding to a position change of the knob 11 moving by the user's pressing or a height change of the knob 11 by the user's pressing.

As shown in Figs. 2 and 3, the knob 11 is buried in the power-off state, provided that the deep depth in the power-off state to the maximum and the deep depth in the power-on state to the minimum so as to protrude in the power-on state. Can be.

The knob 11 changes stepwise in depth according to the degree of the user's pressing.

The knob 11 may remain pressed every time the user presses (see FIG. 2). In addition, the knob 11 may be pushed out by the user and then popped out to its original state when the user releases the push (see FIG. 3).

The knob 11 can be pushed in multiple stages such as 2, 3, and 4 stages by the user.

The digging depth of the knob 11 depends on the degree of the user's pressing, and as the digging depth varies, the hierarchical transition of the function selected by the user is made. For example, as the digging depth of the knob 11 increases, it transitions from the upper layer to the lower layer, and as the digging depth decreases, it transitions from the lower layer to the upper layer.

The display unit 12 displays a screen according to the operation of the knob 11. In particular, when the hierarchical transition occurs by the manipulation of the knob 12, the display unit 12 changes the current screen to the transitioned hierarchical screen. Accordingly, each time the knob 11 is pressed in step by step, the display unit 12 displays a screen on which each layer has been shifted.

In addition, the knob 11 is provided in the main body 10 so as to be rotatable by the user (see FIG. 4).

The knob 11 is provided so that the rotation angle of the knob is changed by the user's rotation operation.

The knob 11 is rotated stepwise according to the degree that the user rotates clockwise or counterclockwise.

The rotation angle of the knob 11 is changed according to the rotation operation of the user. As the rotation angle is changed, the function type is selected, or the attribute value is selected for each layer of the selected function.

When the knob 11 is rotated while a screen having a plurality of function lists is displayed on the display unit 12 so as to select a type of function, the function type is selected in such a manner that the highlighted function is sequentially changed every time it is rotated.

In addition, when the knob 11 is rotated while the hierarchical transition is performed by pressing the knob 11 and the hierarchical screen having a plurality of attribute values is displayed on the display unit 12, the highlighted attribute value is rotated every time the knob 11 is rotated. Attribute value selection is done in a sequential manner.

In this manner, the hierarchical transition is performed by the operation of pressing the knob 11, and the selection of the function type and the attribute value is performed by the operation of rotating the knob 11.

A series of information (function information, hierarchical transition information, and attribute information for each layer) selected by the user according to the pressing operation and the rotation operation of the knob 11 is stored in the memory.

At this time, the execution of the function is performed when the attribute value selection is completed on the screen transitioned to the last layer where no further layer transition can be made by the user's pressing operation. When a user presses a transition to the last layer where a layer transition can no longer be made and selection of attribute values on the last layer screen is completed, the corresponding function is executed based on a series of information stored in the memory.

5 is a control block diagram of a user interface device according to a first embodiment of the present invention.

As shown in FIG. 5, the user interface device includes a depth sensing unit 20, a rotation sensing unit 21, a control unit 30, a storage unit 40, and a display unit 12.

The depth detecting unit 20 detects the cut depth of the knob 11. The depth sensing unit 20 senses the depth of the knob 11 that varies as the user manipulates the knob 11. The depth sensing unit 20 outputs a signal corresponding to the depth information to the control unit 30. The depth sensing unit 20 outputs different signals for each of the digging depths.

The rotation detector 21 detects a rotation angle of the knob 11. The rotation detector 21 detects a rotation angle of the knob 11 that varies as the user rotates the knob 11. The rotation detection unit 21 outputs a signal corresponding to the rotation angle information to the control unit 30. The rotation detecting unit 21 outputs different signals for each rotation angle.

The display unit 12 displays a screen according to the operation of the knob 11. The display unit 12 displays a screen and its screen change according to the pressing and rotating operation of the knob 11.

The controller 30 receives a signal output from the depth sensing unit 20 and recognizes depth information of the .knob 11 according to the signal. The controller 30 determines a layer to transition corresponding to the depth information recognized by the depth sensing unit 20 among the various layers of the function selected by the user, and displays the screen of the determined transition layer to display the screen. 12).

In addition, the control unit 30 receives a signal output from the rotation detecting unit, and recognizes the rotation angle of the knob 11 in accordance with this signal. At this time, the controller 30 determines a selection value corresponding to the recognized rotation angle information according to whether the current screen is a function type selection screen or a layer-specific property selection screen.

The control unit 30 also stores in the storage unit 40 various types of information such as function information, hierarchical transition information, and attribute information for each hierarchical layer generated each time the knob 11 is pressed and rotated.

In addition, the control unit 30 is determined based on the depth information of the knob 11 sensed by the depth sensing unit 20, and as a result, the user transitions to the last layer where no further layer transition can be made by the user's pressing operation. When the attribute value selection on the hierarchical screen is completed, the corresponding function is executed based on a series of information stored in the storage unit 40.

Hereinafter, a method of controlling a user interface device to which a knob (FIG. 2) for holding a pressed state by a user's pressing operation is applied will be described.

6 is a control flowchart of a user interface device according to a first embodiment of the present invention.

Referring to FIG. 6, first, the controller 30 determines whether the power is off (1000). If the determination result of the operation mode 1000 is the power-off state, the control unit 30 detects the depth of the knob 11 (1001), and determines whether there is a pressing operation of the knob 11 (1002).

As a result of the determination of the operation mode 1002, if there is a pressing operation of the knob 11 in the power-off state, the controller 30 causes the display unit 12 to display a screen for selecting the type of function (1003). Accordingly, the user rotates the knob 11 to select a desired type of function among the types of functions displayed on this screen. At this time, the knob 11 pops out to the maximum.

In this state, the controller 30 senses the rotation of the knob 11 (1004), recognizes the type of function selected by the knob rotation, and stores the recognized function value in the storage 40 (1005).

After recognizing and storing the function, the controller 30 senses the depth of the knob 11 (1006) and determines whether there is a pressing operation of the knob 11 (1007). Here, the pushing operation is a knob operation in which the depth of the knob 11 is set in advance by the pressure applied to the knob 11. At this time, the knob 11 continues to enter the preset depth even if the user releases the pressed state.

As a result of the determination of the operation mode 1007, if there is a pressing operation of the knob 11, the function recognized in the operation mode 1005 transitions the layer to the first layer, which is the transition layer corresponding to the preset depth by the pressing operation, and the function at the first layer. In operation 1008, the display 12 displays a first hierarchical screen for selecting a first attribute value. Accordingly, the user rotates the knob 11 to select a desired first attribute value among the attributes displayed on the first hierarchical screen.

In this state, the controller 30 senses the rotation of the knob 11 (1009), and determines whether the first attribute value is selected according to the rotation detection result of the knob 11 (1010). For example, it may be determined that the highlighted attribute value is selected as the first attribute value after a predetermined time elapses after displaying the first hierarchical screen. In this case, the first attribute value is an attribute value selected by the user among a plurality of first attributes displayed on the first hierarchical screen.

If the first attribute value is selected as a result of the determination of the operation mode 1010, the controller 30 recognizes the first attribute value selected by the knob rotation and stores the recognized first attribute value in the storage 40 (1011). .

After recognizing and storing the first attribute value, the controller 30 senses the depth of the knob 11 (1012), and determines whether there is an additional pressing operation of the knob 11 (1013). Here, since the knob 11 is already pressed in the previous operation mode, the depth of the knob 11 has a larger depth value by additional pressing.

As a result of the determination of the operation mode 1013, if there is an additional pressing operation of the knob 11, the function recognized in the operation mode 1005 makes a hierarchical transition to the second layer, which is a transition layer corresponding to the depth corresponding to the additional pressing operation. In operation 1014, the display unit 12 displays a second hierarchical screen for selecting a second attribute value of the function. Accordingly, the user rotates the knob 11 to select a desired second attribute value from the plurality of second attributes displayed on the second hierarchical screen. For reference, assuming that the knob 11 is fully inserted and embedded by this additional pressing operation, the controller 40 senses the depth of the knob 11 and recognizes that there is no layer to transition to. , Prepare to execute the function.

In this state, the controller 30 senses the rotation of the knob 11 (1015), and determines whether the second attribute value is selected according to the rotation detection result of the knob 11 (1016). For example, it may be determined that the highlighted attribute value is selected as the second attribute value after a predetermined time elapses after displaying the second hierarchical screen. In this case, the second attribute value is an attribute value selected by the user among a plurality of attributes displayed on the second hierarchical screen.

If the second attribute value is selected as the result of the determination of the operation mode 1016, the controller 30 recognizes the second attribute value selected by the knob rotation and stores the recognized second attribute value in the storage 40 (1017). .

After recognizing and storing the second attribute value, the controller 30 executes the function based on the function value, the first attribute value, and the second attribute value stored in the storage 40 (1018). Thereafter, when the execution of the function is completed, the power supply of the user interface device 1 is automatically turned off.

Hereinafter, a control method of a user interface device to which a knob (see FIG. 3) pressed by a user's pressing operation and pops out to an original state is applied.

7 is another control flowchart of the user interface device according to the first embodiment of the present invention.

Referring to FIG. 7, first, the control unit 30 determines whether it is in a power-off state (2000), and if it is in a power-off state, detects the depth of the knob 11 (2001) and whether there is a one-step pressing operation of the knob 11. (2002).

As a result of the determination of the operation mode 2002, if there is a one-step operation of the knob 11 in the power-off state, the control unit 30 causes the display unit 12 to display a screen for selecting the type of function (2003). At this time, the knob 11 pops out to the maximum.

In this state, the controller 30 senses the rotation of the knob 11 (2004), recognizes the type of function selected by the knob rotation, and stores the recognized function value in the storage 40 (2005).

After recognizing and storing the function, the controller 30 senses the depth of the knob 11 (2006) and determines whether there is a one-step pressing operation of the knob 11 (2007). Here, the one-step pressing operation is a knob operation in which the recessed depth of the knob 11 is a first depth by the pressure applied to the knob 11. At this time, the knob 11, which is operated by pressing in one step, pops out to its original state the moment the user releases the pressing.

As a result of the determination in the operation mode 2007, if there is a one-step pressing operation of the knob 11, the function transitions to the first layer, which is the transition layer corresponding to the first depth by the one-step pressing operation, in the function recognized in the operation mode 2005. The first hierarchical screen for selecting the first attribute value of the function in the hierarchy is displayed on the display unit 12 (2008). Accordingly, the user rotates the knob 11 to select a desired first attribute value among the attributes displayed on the first hierarchical screen.

In this state, the controller 30 senses the rotation of the knob 11 (2009), and determines whether the first attribute value is selected according to the rotation detection result of the knob 11 (2010). For example, it may be determined that the highlighted attribute value is selected as the first attribute value after a predetermined time elapses after displaying the first hierarchical screen. In this case, the first attribute value is an attribute value selected by the user among a plurality of first attributes displayed on the first hierarchical screen.

If the first attribute value is selected as the determination result of the operation mode 2010, the controller 30 recognizes the first attribute value selected by the knob rotation and stores the recognized first attribute value in the storage 40 (2011). .

After recognizing and storing the first attribute value, the controller 30 senses the depth of the knob 11 (2012), and determines whether there is a two-step pressing operation of the knob 11 (2013). Here, the two-step pressing operation is a knob operation in which the depth of the knob 11 is the second depth by the pressure applied to the knob 11.

As a result of the determination of the operation mode 2013, if there is a two-step pressing operation of the knob 11, the function transitions to the second layer, which is the transition layer corresponding to the second depth by the two-step pressing operation, in the function recognized in the operation mode 2005, The second hierarchical screen for selecting a second attribute value of the function in the hierarchy is displayed on the display unit 12 (2014). Accordingly, the user rotates the knob 11 to select a desired second attribute value from the plurality of second attributes displayed on the second hierarchical screen. For reference, assuming that the knob 11 is fully inserted and embedded by a two-stage pressing operation, the controller 40 detects the depth of the knob 11 and recognizes that there is no hierarchy to transition to. , Prepare to execute the function.

In this state, the controller 30 detects the rotation of the knob 11 (2015), and determines whether the second attribute value is selected according to the rotation detection result of the knob 11 (2016). For example, it may be determined that the highlighted attribute value is selected as the second attribute value after a predetermined time elapses after displaying the second hierarchical screen. In this case, the second attribute value is an attribute value selected by the user among a plurality of attributes displayed on the second hierarchical screen.

If the second attribute value is selected as the determination result of the operation mode 2016, the controller 30 recognizes the second attribute value selected by the knob rotation and stores the recognized second attribute value in the storage 40 (2017). .

After recognizing and storing the second attribute value, the controller 30 executes the function based on the function value, the first attribute value, and the second attribute value stored in the storage 40 (2018). Thereafter, when the execution of the function is completed, the power supply of the user interface device 1 is automatically turned off.

8 is a configuration diagram for explaining that the user interface device according to the first embodiment of the present invention is applied to a washing machine. 9 to 11 are diagrams for explaining screens for each layer according to a user's pressing operation in a washing machine to which a user interface device according to a first embodiment of the present invention is applied.

As shown in FIG. 8, the user interface device 1 displays a knob 11 provided to be pressed and rotated to operate the washing machine, and a setting screen of the washing machine according to the operation of the knob 11. And a display unit 12.

As shown in FIG. 9, the display unit 12 displays a screen 50 having a function icon list 50a-50d indicating a type of a washing machine.

The function icon list 50a-50d includes the " favorite icon " 50a, the " eco icon " 50b, the " wash cycle icon " 50c, " Wash delay icon "50d.

As shown in Figs. 10 and 11, for example, the echo function corresponding to the "eco icon" 50b is composed of a first layer and a second layer which are sequential lower layers. Each time a hierarchical transition occurs, the screens 51 and 52 for each layer are sequentially displayed on the display unit 12.

The first hierarchical screen 51 of the "eco icon" 50b is "300" (51a), "400" (51b), "500" (51c), "700" (51d), and "900" (51e). And hierarchical icons for selecting a spin speed such as “1300” 51f are displayed by the user so as to be selectable (see FIG. 10).

In addition, the second hierarchical screen 52 of the "eco icon" 52 has hierarchical icons 52a-52d for selecting laundry types such as general clothes, colored clothes, feathers and wool, and washing temperature. It is displayed to be selectable (refer FIG. 11).

12 is a view for explaining a user interface in the washing machine to which the user interface device according to the first embodiment of the present invention is applied.

As shown in FIG. 12, when the washing machine is turned off, the knob 11 is embedded in the front surface of the main body of the user interface device in the washing machine user interface device.

When the user presses the knob 11 to operate the washing machine, the knob 11 pops out to the front while being embedded in the main body 10. Power is supplied to the washing machine by the depth change of the knob 11 generated when the knob 11 embedded in the front of the main body pops out.

The Knob 11 pops up from the front of the main unit, and the "Favorite icon" 50a, the "Eco icon" 50b, the "Laundry cycle icon" 50c and the "Laundry delay icon" can be selected to select the function type. A screen 50 having " 50d 'is displayed on the display unit 12. FIG.

For example, initially the "favorite icon" 50a may be highlighted, and when the user rotates the knob clockwise, the highlight of the "favorite icon" 50a will be turned off and the "favorite icon" 50a will be highlighted. The "eco icon" 50b located on the right side is highlighted. Accordingly, the user may know that the "eco icon" is selected.

To set the echo function, the user rotates the knob 11 clockwise to position the “eco icon” 50b, and then presses the knob 11 one step, so that the spin speed icon “300” can be selected. The first hierarchical screen 51 having the screens 51a, 400, 51b, 500, 51c, 700, 51d, 900, 51e, and 1300, 51f is displayed. It is displayed at (12). At this time, the knob 11 is in the state of being pressed by one stage.

For example, initially, the spin speed "500" 51c may be highlighted, and when the user turns the knob clockwise, "700" 51d located to the right of "500" 51c is highlighted. Accordingly, the user may know that "700" is selected.

To set the spin speed of the echo function, the user turns the knob clockwise to position "700" (51d), and then presses the knob 11 one step further to select the type of laundry and the washing temperature. ) Is displayed on the display unit 12. On this screen 52, various laundry type / laundry temperature icons 52a-52d for selecting the washing temperature for each kind of laundry are displayed. At this time, the knob 11 is in a two-stage pressurized state.

The user turns the knob 11 clockwise to select an icon corresponding to the desired laundry type and the washing temperature. For example, the user turns the knob clockwise to highlight the "feather cold water" 52c located four squares to the right from the default highlighted "40 degree color" 52a.

The user rotates the knob 11 to place the icon on the icon corresponding to the desired laundry type and washing temperature, and then presses the knob 11 one step further. The total washing time, function type information, dehydration speed information, and laundry type / A screen summarizing that the washing temperature information and the like is selected is displayed on the display unit 12. For example, 42 minutes and 08 seconds representing the total washing time, an eco function icon representing the eco function, 700 turn / min representing the spin speed, an icon corresponding to the laundry type / washing temperature, and the like are displayed. At this time, the hierarchical level of the knob pressed by the user is the last hierarchical state which can no longer be pressed, and the knob 11 is fully buried in a two-stage pressed state.

The above display information is displayed on the display unit 12 and the echo function is executed.

For reference, if the user wants to pause the washing machine while executing the function, the user can pause the knob 11 by pressing the knob 11. At this time, the pause can be made by pressing the knob 11 again.

On the other hand, in the above embodiment, the function execution is automatically performed by the operation of selecting the attribute value on the last hierarchical screen, but the present invention is not limited thereto. In executing the function execution, the knob 11 is pressed once more last. It is also possible to configure so that. For example, when the last three steps are pressed after two steps of pressing the knob 11 provided to enable three steps, the corresponding function can be executed.
