DETAILED DESCRIPTION

Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.

FIG. 1 is a drawing illustrating the configuration of a user interface device in accordance with an embodiment of the present disclosure. FIG. 2 is a drawing illustrating an example of the manipulation of a knob in the user interface device in accordance with an embodiment of the present disclosure. FIG. 3 is a drawing illustrating another example of the manipulation of a knob in the user interface device in accordance with an embodiment of the present disclosure. FIG. 4 is a drawing illustrating the manipulation direction of the knob in the user interface device in accordance with an embodiment of the present disclosure.

Referring to FIG. 1, a user interface device 1 includes a knob 11 and a display unit 12 that are provided at one side of a body 10 of the user interface device 1. The knob 11 may be provided adjacent to the display unit 12.

The knob 11 is provided on the body 10 to enable a pressing operation by a user.

The knob 11 is configured to implement a multistage pressing, for example, pressing into stage one, stage two, and stage three, such that the degree of the knob 11 being pressed varies with the pressing manipulation of a user. The knob 11 is configured to provide a different retraction depth according to the degree of the knob 11 pressed by a user. The retraction depth of the knob 11 may represent a value corresponding to the change in position of the knob 11 that is moved according to the pressing of a user, or a value corresponding to the change in height of the knob 11 that is moved according to the pressing of a user.

Referring to FIGS. 2 and 3, the knob 11 is configured to be buried, or retracted, at a power-off state and be ejected, or extended, at a power-on state such that the knob 11 has a maximum retraction depth at the power-off state and has a minimum retraction depth at the power-on state.

The retraction depth of the knob 11 is changed in a stepwise manner according to the degree of the knob 11 being pressed by a user.

Whenever a user presses the knob 11, the knob 11 may retain a pressed state (see FIG. 2). Alternatively, the knob 11 may be extended to the original state when the knob 11 is no longer being pressed (see FIG. 3).

The knob 11 may be pressed by a user in a multistage manner, such as in a two-stage manner, a three-stage manner, and a four-stage manner, for example.

The retraction depth of the knob 11 varies with the degree of the knob 11 being pressed by a user, and according to the retraction depth varied, a class, or an option group, transition of a function selected by a user is achieved. For example, as the retraction depth of the knob 11 is increased, an option group transition from an upper option group to a lower option group is performed, and as the retraction depth of the knob 11 is decreased, an option group transition from a lower option group to an upper option group is performed.

The display unit 12 displays a screen corresponding to the manipulation of the knob 11. In particular, when an option group transition occurs by the manipulation of the knob 11, the display unit 12 changes a current screen to a screen of an option group to which the option group transition is made. Accordingly, whenever the knob 11 is pressed in stages, a screen of an option group to which an option group transition is made is displayed on the display unit 12.

In addition, the knob 11 is provided on the body 10 to enable a rotation manipulation by a user (see FIG. 4).

The knob 11 is configured to have an angle of rotation thereof varying according to the manipulation of rotation by a user.

The knob 11 has an angle of rotation changed in stepwise according to the degree of clockwise or counterclockwise rotation of the knob 11 by a user.

The angle of rotation of the knob 11 varies with the manipulation of rotation by a user, and according to the angle of rotation, the selection of the type of a function is achieved or the selection of an attribute, or option value of each option group of the selected function is achieved.

To select the type of a function on the display unit 12, in a display state of a screen having a list of a plurality of functions, if the knob 11 is rotated, a highlighted function is consecutively changed whenever the knob 11 is rotated, so that the selecting of the type of a function is achieved.

In addition, the option group transition is achieved by the pressing operation of the knob 11, and in a state of displaying an option group screen having a plurality of option values on the display unit 12, if the knob 11 is rotated, an option value is consecutively changed whenever the knob 11 is rotated, so that the selecting of an option value is achieved.

As described above, the option group transition is achieved by the pressing operation of the knob 11, and the selecting of the type of a function or the selecting of an option value is achieved by the rotating operation of the knob 11.

A series of information selected by a user according to the pressing manipulation and the rotating manipulation of the knob 11, such as function information, option group transition information, and option information of each option group, for example, is stored in a memory.

The execution of a function is achieved when the selecting of an option value is completed on a screen of a last option group, from which an option group transition is completed by the pressing manipulation by a user. If an option group transition is made to a last option group, from which an option group transition is completed, and a selecting of an option value on the screen of the last option group is completed, the corresponding function is executed based on a series of information stored in the memory.

FIG. 5 is a control block diagram showing the user interface device in accordance with an embodiment of the present disclosure.

Referring to FIG. 5, the user interface device includes a depth sensor unit 20, a rotation sensor unit 21, a control unit 30, a storage unit 40, and a display unit 12.

The depth sensor unit 20 senses the depth by which the knob 11 is retracted. The depth sensor unit 20 senses the depth, by which the knob 11 is retracted, changed by the manipulation of the knob 11 by a user. The depth sensor unit 20 outputs a signal corresponding to the depth information to the control unit 30. The depth sensor unit 20 outputs a different signal if a different retraction depth is detected.

The rotation sensor unit 21 senses the angle of rotation of the knob 11. The rotation sensor unit 21 senses the angle of rotation of the knob 11 varying with the rotation of the knob 11 by the user. The rotation sensor unit 21 outputs a signal corresponding to the rotation angle information to the control unit 30. The rotation sensor unit 21 outputs a different signal if a different degree of rotation is detected.

The display unit 12 displays a screen according to the manipulation of the knob 11. The display unit 12 displays a screen and the change of a screen according to the pressing manipulation and the rotation manipulation of the knob 11.

The control unit 30 receives the signal being output from the depth sensor unit 20, and recognizes the depth information of the knob 11 based on the signal. The control unit 30 determines an option group, to which an option group transition is to be made, corresponding to the depth information recognized by the depth sensor unit 20 among a plurality of option groups of the function selected by a user, and controls the display unit 12 to display a screen of the determined option group.

In addition, the control unit 30 receives a signal being output from the rotation sensor unit 21, and recognizes the angle of rotation of the knob 11 based on the signal. In this case, the control unit 30, depending on whether a current screen is a screen to select a function type or a screen to select an option value of each option group, determines a selection value corresponding to the recognized rotation angle.

In addition, the control unit 30 stores various information, such as function information, option group transition information, and option information of each option group, for example, which are generated whenever a pressing manipulation and a rotation manipulation of the knob 11 are performed, in the storage unit 40.

In addition, the control unit 30, if it is determined that an option group transition to the last option group, from which an option group transition is completed, is performed by the pressing manipulation of a user, based on the depth information of the knob 11 sensed through the depth sensor unit 20, and determined that a selection of an option value on the last option group is completed, executes the corresponding function based on the series of information stored in the storage unit 40.

Hereinafter, a method of controlling a user interface device applied with the knob, shown in FIG. 2, which remains in a pressed state by the pressing manipulation by a user.

FIGS. 6A and 6B are a control flow chart showing the user interface device in accordance with an embodiment of the present disclosure.

The control unit 30 determines whether a current state is a power off state (operation 1000). If it is determined from operation 1000 that the current state is the power off state, the control unit 30 senses the depth of the knob 11 (operation 1001) and determines whether a pressing manipulation of the knob 11 is present (operation 1002).

If it is determined from operation 1002 that a pressing manipulation is present at the power off state, the control unit 30 displays a screen to select a type of function on the display unit 12 (operation 1003). Accordingly, the user selects a desired type of function among a plurality of types of functions being displayed on the screen, by rotating the knob 1. In this case, the knob 11 is extended to the maximum degree.

Thereafter, the control unit 30 senses the rotation of the knob 11 (operation 1004), recognizes the type of function selected by the rotation of the knob 11, and stores a value of the recognized function in the stored unit 40 (operation 1005).

After the function is recognized and stored, the control unit 30 senses the depth of the knob 11 (operation 1006), and determines whether a pressing manipulation of the knob 11 is present (operation 1007). The pressing manipulation represents a manipulation of the knob 11 having a retraction depth of the knob 11 at a predetermined depth according to the pressure on the knob 11. Even at the time of releasing the pressure by the user, the knob 11 retains the predetermined depth of retraction.

If it is determined from operation 1007 that a pressing manipulation of the knob 11 is present, a transition is made to a first option group corresponding to the predetermined depth that is formed by the pressing manipulation at the function recognized from the operation 1005, and a first option group screen to select a first option value of the function at the first option group is displayed on the display unit 12 (operation 1008). Accordingly, the user 11 selects a desired first option value among a plurality of first option values being displayed on the first option group screen by rotating the knob 11.

At this state, the control unit 30 senses the rotation of the knob 11 (operation 1009), and according to the result of sensing the rotation of the knob 11, determines whether the first option value is selected (operation 1010). For example, an option value being highlighted at a predetermined point of time after the first option group screen is displayed is a first option value that is selected. In this case, the first option value is an option value selected by a user among a plurality of first option values displayed on the first option group screen.

If it is determined from operation 1010 that the first option value is selected, the control unit 30 recognizes the first option value selected by the rotation of the knob, and stores the recognized first option value in the storage unit 40 (operation 1011).

After the first option value is recognized and stored, the storage unit 30 senses the depth of the knob 11 (operation 1012) to determine whether an additional pressing manipulation of the knob 11 is present (operation 1013). Because the knob 11 is in a state of being pressed by the previous operation mode, the knob 11 has a depth value increased by the additional pressing manipulation.

If it is determined from the operation 1013 that an additional pressing manipulation is present, an option group transition is made to a second option group, which corresponds to a depth that is formed by the additional pressing manipulation, at the function recognized from the operation 1005, and a second option group screen to select a second option value of the function at the second option group is displayed on the display unit 12 (operation 1014). Accordingly, the user 11 selects a desired second option value among a plurality of second option values being displayed on the second option group screen by rotating the knob 11. When assumed that the knob 11 is completely retracted by the additional pressing manipulation, the control unit 40 senses the depth of the knob 11 and recognizes an absence of an option group to which the option group transition is made, and prepares for the execution of the corresponding function.

At this state, the control unit 30 senses the rotation of the knob 11 (operation 1015), and according to the result of sensing the rotation of the knob 11, determines whether the second option value is selected (operation 1016). For example, an option value being highlighted at a predetermined point of time after the second option group screen is displayed is a second option value that is selected. In this case, the second option value is an option value selected by a user among a plurality of second option values displayed on the second option group screen.

If it is determined from operation 1016 that the second option value is selected, the control unit 30 recognizes the second option value selected by the rotation of the knob 11, and stores the recognized second option value in the storage unit 40 (operation 1017).

After the second option value is recognized and stored, the control unit 30 executes the corresponding function based on the function value, the first option value and the second option value that are stored in the storage unit 40 (operation 1018). Thereafter, as the execution of the function is completed, the user interface device 1 may automatically enter a power-off state.

Hereinafter, a method of controlling a user interface device applied with the knob, shown in FIG. 3, which is extended after being pressed by the pressing manipulation by a user.

FIGS. 7A and 7B are a control flow chart showing the user interface device in accordance with an embodiment of the present disclosure.

The control unit 30 determines whether a current state is a power-off state (operation 2000). If it is determined from the operation 2000 that the current state is the power-off state, the control unit 30 senses the depth of the knob 11 (operation 2001) to determine whether a first-stage pressing manipulation of the knob 11 is present (operation 2002).

If it is determined from operation 2002 that a first-stage pressing manipulation is present at the power-off state, the control unit 30 displays a screen to select the type of a function on the display unit 12 (operation 2003). At this state, the knob 11 is extended to the maximum degree.

Thereafter, the control unit 30 senses the rotation of the knob 11 (operation 2004), recognizes the type of function selected by the rotation of the knob 11, and stores a value of the recognized function in the stored unit 40 (operation 2005).

After the function is recognized and stored, the control unit 30 senses the depth of the knob 11 (operation 2006), and determines whether the first-stage pressing manipulation of the knob 11 is present (operation 2007). The first-stage pressing manipulation represents a manipulation of the knob 11 having a retraction depth of the knob 11 at a first depth according to the pressure on the knob 11. When the pressure by the user is released, the knob 11 is extended to the original state.

If it is determined from operation 2007 that the first-stage pressing manipulation of the knob 11 is present, an option group transition is made to a first option group corresponding to the first depth that is formed by the first-stage pressing manipulation, at the function recognized from the operation 2005, and a first option group screen to select a first option value of the function at the first option group is displayed on the display unit 12 (operation 2008). Accordingly, the user 11 selects a desired first option value among a plurality of first option values being displayed on the first option group screen by rotating the knob 11.

At this state, the control unit 30 senses the rotation of the knob 11 (operation 2009), and according to the result of sensing the rotation of the knob 11, determines whether the first option value is selected (operation 2010). For example, an option value being highlighted at a predetermined point of time after the first option group screen is displayed is a first option value that is selected. In this case, the first option value is an option value selected by a user among a plurality of first option values displayed on the first option group screen.

If it is determined from operation 2010 that the first option value is selected, the control unit 30 recognizes the first option value selected by the rotation of the knob 11, and stores the recognized first option value in the storage unit 40 (operation 2011).

After the first option value is recognized and stored, the storage unit 30 senses the depth of the knob 11 (operation 2012) and determines whether a second-stage pressing manipulation of the knob 11 is present (operation 2013). The second-stage pressing manipulation represents a manipulation of the knob 11 having a retraction depth of the knob 11 at a second depth according to the pressure on the knob 11.

If it is determined from operation 2013 that the second-stage pressing manipulation is present, an option group transition is made to a second option group, which corresponds to the second depth that is formed by the second-stage pressing manipulation, at the function recognized from the operation 2005, and a second option group screen to select a second option value of the function at the second option group is displayed on the display unit 12 (operation 2014). Accordingly, the user 11 selects a desired second option value among a plurality of second option values being displayed on the second option group screen by rotating the knob 11. When assumed that the knob 11 is completely retracted by the second-stage pressing manipulation, the control unit 40 recognizes the absence of an option group to which a transition is made by sensing the depth of the knob 11, and prepares for execution of the corresponding function.

At this state, the control unit 30 senses the rotation of the knob 11 (operation 2015), and according to the result of sensing the rotation of the knob 11, determines whether the second option value is selected (operation 2016). For example, an option value being highlighted at a predetermined point of time after the second option group screen is displayed is a second option value that is selected. In this case, the second option value is an option value selected by a user among a plurality of option values displayed on the second option group screen.

If it is determined from operation 2016 that the second option value is selected, the control unit 30 recognizes the second option value selected by the rotation of the knob 11, and stores the recognized second option value in the storage unit 40 (operation 2017).

After the second option value is recognized and stored, the control unit 30 executes the corresponding function based on the function value, the first option value and the second option value that are stored in the storage unit 40 (operation 2018). Thereafter, as the execution of the function is completed, the user interface device 1 may automatically enter the power-off state.

FIG. 8 is a diagram illustrating the configuration of a washing machine provided with the user interface device in accordance with an embodiment of the present disclosure. FIGS. 9 to 11 are diagrams illustrating screens by option groups according to the pressing operation of a user in the washing machine applied with the user interface device in accordance with an embodiment of the present disclosure.

Referring to FIG. 8, the user interface device 1 includes the knob 11 configured to be pressed and rotated for the operation of a washing machine, and a display unit 12 to display a setting screen of the washing machine according to the manipulation of the knob 11.

Referring to FIG. 9, the display unit 12 displays a screen 50 having a function icon list representing the types of functions of the washing machine.

For example, the function icon list includes a favorite icon 50a, an eco icon 50b, a wash cycle icon 50c, and a wash delay icon 50d. However, the disclosure is not limited to the display described above.

Referring to FIGS. 10 and 11, for example, an eco function corresponding to the eco icon 50b includes a first option group and a second option group that are subsequent in order. As the option group transitions occur, screens 51 and 52 are sequentially displayed by option groups on the display unit 12.

The first option group screen 51 of the eco icon 50b has option group icons, which are configured to select the spin dry speed, such as “300” 51a, “400” 51b, “500” 51c, “700” 51d, “900” 51e, and “1300” 51f, displayed to enable a selection by a user (see FIG. 10).

In addition, the second option group 52 of the eco icon 50b has option group icons, which are configured to select the type of laundry and the temperature of washing operation, such as normal clothes 52a, color clothes 52b, feather clothes 52c, wool clothes 52d, and agitation 52e, displayed to enable a selection by a user (see FIG. 11).

FIG. 12 is a drawing illustrating a user interface in the washing machine applied with the user interface device in accordance with an embodiment of the present disclosure.

Referring to FIG. 12, in a power-off state of the washing machine, the user interface device 1 of the washing machine has the knob 11 retracted from the front surface of the body 10 of the user interface device 1.

If a user presses the knob 11 to operate the washing machine, the knob 11 is extended to the front surface from being retracted in the body 10. According to the change of depth of the knob 11 generated when the knob 11 retracted in the front surface of the body is extended, the washing machine is powered on.

At the same time when the knob 11 is extended from the front surface of the body, the screen 50 having the favorite icon 50a, the eco icon 50b, the wash cycle icon 50c, and the wash delay icon 50d is displayed on the display unit 12 such that the type of function is selected.

For example, in the beginning, the favorite icon 50a may be highlighted, and if a user rotates the knob 11 clockwise, the highlight of the favorite icon 50a is turned off and the eco icon 50b located at the right side of the favorite icon 50a is highlighted. Accordingly, the user is informed that the eco icon is selected.
