2. Description of the Related Art
A set-top box is connected to a television, converts properly a video signal and a voice signal received from an external device and displays an image corresponding to the converted video and voice signal through the television.
The set-top box receives an IPTV signal, a cable TV signal, a satellite TV signal or a general signal for broadcasting, and the set-top box displays the received signal on the television.
The set-top box generally interoperates with a wired or wireless controller. A user remotely controls the set-top box with the remote controller.
Functions of the set-top box or the television are diversified as types of contents and services provided from an IPTV, a cable TV or a satellite TV have been diversified. The number of buttons or keys in the remote controller controlling the set-top box or the television has increased due to the diversification of the functions.
It is preferable to provide various contents and services to the user, but the user need to know a function of each button in the remote controller in order to fully enjoy the various contents and services provided.
It becomes difficult for the user to control the remote controller with keeping the user's eyes toward the television (blind control) because the remote controller has lots of buttons or keys. Additionally, there are many factors distracting user's view when the user controls the remote controller. For example, the user should look at the remote controller and select a relevant button whenever the user wants to properly control the remote controller.
A demand for a remote controller having few or no button has been on the rise. Since a conventional remote controller does not satisfy such demand, a system and method for controlling the remote controller having few or no button is needed while allowing the user to enjoy a variety of contents and services. With the remote controller having few or no button, the user may easily figure out how to use the remote controller and it also enables the user to perform the blind control when using the remote controller.

DETAILED DESCRIPTION
In the present specification, an expression used in the singular encompasses the expression of the plural, unless it has a clearly different meaning in the context.
In the present specification, terms such as “comprising” or “including,” etc., should not be interpreted as meaning that all of the elements or operations are necessarily included. That is, some of the elements or operations may not be included, while other additional elements or operations may be further included.
Also, terms such as “unit,” “module,” etc., as used in the present specification may refer to a part for processing at least one function or action and may be implemented as hardware, software, or a combination of hardware and software.
Hereinafter, embodiments of the invention will be described in detail with reference to accompanying drawings.
FIG. 1 is a view illustrating a media system according to one embodiment of the invention.
The media system of the present embodiment includes a remote controller 100 and an image processing terminal 200.
Here, the remote controller 100 includes at least one key for controlling the image processing terminal 200 (including hardware control and software control), and transmits a control signal in response to a sensing level of a key to the image processing terminal 200.
In this case, the image processing terminal 200 may perform different operations according to the sensing levels of the key selected by a user.
Here, the sensing level of the key corresponds to pressure applied (touched) to the key of the remote controller 100 by the user. If the key of the remote controller 100 is matched with three dimensional coordinate (x, y, z), the sensing level may be expressed with a coordinate (z) in a direction vertical to a plane of the key.
The sensing level may depend on the area of the key pressed (touched) with the pressure, and correspond to a coordinate (x, y).
Accordingly, both the coordinate of the selected key and the sensing level may be expressed in a three-dimensional coordinate (x, y, z).
However, other methods may be used to express the coordinate and the sensing level of the selected key.
Hereinafter, it is assumed that the sensing level is determined by using the coordinate (z) of the three dimensional coordinate, i.e. the pressure applied to the key by the user.
The remote controller 100 may transmit a control signal (hereinafter, referred to as “C(x, y, z)”) including a coordinate (x, y, z) of corresponding key to the image processing terminal 200, when the user selects a key with a specific sensing level.
If a value of the coordinate (z) of the selected key by the user (i.e. pressure applied to the key by the user) is less than a predetermined reference value, the image processing terminal 200 may determine an input corresponding to the value as a normal press. If the value of the coordinate (z) of the selected key by the user is more than the predetermined reference value, the image processing terminal 200 may determine an input corresponding to the value as a force press for selecting the key with further pressure or area. Accordingly, the image processing terminal 200 may perform different operations according to the pressure applied to the same key by the user.
In one embodiment, a middle input (hereinafter, referred to as “force input”) between the normal press and the force press may exist according to the coordinate (z) of the key selected by the user. The image processing terminal 200 may perform an operation corresponding to the force input.
Here, the force input is an input that exceeds a value of a coordinate (z) corresponding to the sensing level of the normal press as further pressure is applied to the key while the pressing or a touching to the key still remains after the normal press. The force press is an input that exceeds the value of a coordinate (z) corresponding to the sensing level of the force input as further pressure is applied to the key while the pressing or a touching to the key still remains after the force input.
Hereinafter, the keys of the remote controller 100 and the sensing level will be described in detail.
The key of the remote controller 100 may be implemented by hardware including dome key type, or implemented by software.
The image processing terminal 200 may be a display device such as a television (TV) for displaying an image or a device such as a set-top box for transmitting an image signal to the display device.
That is, the image processing terminal 200 is not limited as a specific device as long as it processes the image. The image processing terminal 200 may be the set-top box or a television having a function of the set-top box.
The image processing terminal 200 may receive the control signal C(x, y, z) about the key selected by the user from the remote controller 100, and determine the types of inputs from the received control signal.
In the event that the sensing level is determined to be the force input, the image processing terminal 200 may perform a Graphic User Interface (GUI) effect for an object or a task at which a cursor locates among plural objects displayed on a screen.
In the event that the sensing level is determined to be the force press, the image processing terminal 200 may perform a different operation of the key according to a type of tasks displayed on the present screen, an identifier of the key and a control command corresponding to the identifier of the key. The different operation may be a change of an object displayed on the screen or a scene transition of contents.
Here, the object may include a user interface such as a menu, a button and an icon of an executable application, etc. and contents such as an image, a moving picture and so on. The change of the object may include at least one of a change of the type of the object, the size of the object, the number of the object, or a change of arrangement displayed on the screen according to the size or the number.
The scene transition of the contents may include a transition of the screen in whole or in part into another screen according to a display of detailed information about the contents, a preview of contents selected or contents recently used.
Hereinafter, the operation of the image processing terminal 200 according to the sensing level corresponding to the control signal received from the remote controller 100 will be described in detail.
FIG. 2 is a view illustrating a remote controller according to one embodiment of the invention.
The remote controller 100 may comprise a body 110, a navigation key 120 including up, down, left, or right directional keys, a function key 130 for performing a variety of operations such as an esc key and a home key, and a determination key 140 for performing an operation such as an OK key.
On the other hand, various keys may exist in the remote controller 100, but these keys may be classified as the navigation key 120, the function key 130 and the determination key 140.
The remote controller 100 may be connected to the image processing terminal 200 via wireless communication, and control the operations of the image processing terminal 200.
For example, the remote controller 100 may control a program guide (EPG) displayed on the image processing terminal 200 (e.g., the television).
In one embodiment, a function related to two or more operations of the image processing terminal 200 may be set to at least one of the keys in the remote controller 100.
Particularly, the remote controller 100 may transmit a control signal to the image processing terminal 200. The control signal for performing different operations may be generated according to pressure or an area applied to the key by a touch means such as a finger and any input device.
Here, the remote controller 100 may transmit the control signal C(x, y, z) to the image processing terminal 200. The control signal includes the three dimensional coordinate in accordance with the pressure applied to the key by the user.
For example, when the user presses the navigation key 120 corresponding to a right directional key with a normal press, the remote controller 100 may transmit a control signal C1 having a coordinate (x, y, z1) corresponding to the normal press to the image processing terminal 200.
In the event that further pressure is applied to the key while pressing or touching to the key still remains after the normal press, the remote controller 100 may transmit a control signal C2 having a coordinate (x, y, z2) corresponding to a force input to the image processing terminal 200.
In the event that further pressure is applied to the key while pressing or touching to the key still remains after the force input, the remote controller 100 may transmit a control signal C3 having a coordinate (x, y, z3) corresponding to a force press to the image processing terminal 200.
On the other hand, the force press may be activated when the force input is inputted to the remote controller 100.
Subsequently, the image processing terminal 200 may perform different operations according to the control signal C1, C2 or C3 received from the remote controller 100.
For example, the image processing terminal 200 may perform an operation of displaying a program guide in response to the first control signal C1 corresponding to the normal press, and gradually magnify a size of a program at which a cursor locates in response to the second control signal C2 corresponding to the force input. The image processing terminal 200 may play back the program whose size is magnified in Picture In Picture (PIP) on a certain area of a screen in response to the third control signal C3 corresponding to the force press.
That is, the image processing terminal 200 may perform different operations corresponding to the normal press, the force input or the force press in response to the sensing level that is determined based on the pressure applied to the same key of the remote controller 100 by the user.
Here, the image processing terminal 200 may perform an operation of displaying the program guide if it is the television, and may perform an operation of transmitting an image signal related to the program guide to the television if it is the set-top box.
The remote controller 100 may transmit a control signal including direct command requesting to operate a specific function to the image processing terminal 200. However, the remote controller 100 may also transmit the control signal including the three dimensional coordinate (x, y, z) corresponding to the key selected by the user to the image processing terminal 200.
In this time, an operation related to the three dimensional coordinate (x, y, z) may be determined by the image processing terminal 200.
Accordingly, though the remote controller 100 transmits the same three dimensional coordinate about the same key to the image processing terminal 200, the image processing terminal 200 may perform different operations according to software installed therein.
A user's gesture, sequentially touching keys with sliding in a specific direction, may be inputted to the remote controller 100. The remote controller 100 may transmit a control signal including information concerning the gesture to the image processing terminal 200.
The image processing terminal 200, receiving the control signal including the information concerning the gesture from the remote controller 100, may perform an operation corresponding to the received control signal.
Hereinafter, the sensing level in light of embodiments of the invention will be described in detail with reference to accompanying drawings FIG. 3A, FIG. 3B, FIG. 4A and FIG. 4B.
FIG. 3A is a view illustrating a sensing level according to one embodiment of the invention, and FIG. 3B is a view illustrating an operation of an image processing terminal according to the sensing level in FIG. 3A.
An input corresponding to the sensing level of the present embodiment may include a normal press and a force press as shown in FIG. 3A.
The normal press means the same input as an input in conventional remote controller, and the force press refers to an input when further pressure is applied to a key while pressing or touching to the key still remains after the normal press.
That is, if further pressure is not applied to the coordinate (z) of a key while the user applies the normal press to the key for a long time (long press), the long press may be determined to be the normal press, not the force press.
The force press means an input when the sensing level that exceeds a scope of a value of a coordinate (z) or the value of a coordinate (z) corresponding to the normal press as further pressure is applied to the key while the pressing or touching to the key still remains after the normal press.
For example, as shown in FIG. 3A and FIG. 3B, in the event that the user applies the normal press to an OK key of the remote controller 100 while a cursor locates at specific contents, the specific contents may be played back on a whole area of a screen.
On the other hand, in the event that the user applies the force press to the OK key of the remote controller 100 while the cursor locates at the specific contents, the contents may be played back in picture in picture (PIP) on a certain area of the screen.
Further, the force press may be classified as a force up and a force down.
In one embodiment, the force press may be determined as the force up when the force press is applied to an up direction key in the navigation key 120 depicted in FIG. 2. In addition, the force press may be determined as the force down when the force press is applied to a down directional key in the navigation key 120 depicted in FIG. 2.
For example, a recommendation program may be displayed when the force press is applied to the up directional key while a home screen is being displayed. A video on demand (VOD) list may be displayed when the force press is applied to the down directional key while the home screen is being displayed.
In this case, the recommendation program is displayed when the force press is applied to the up directional key while the home screen is being displayed, and then a screen on which the recommendation program is displayed is returned to the home screen when the force press is applied to the down directional key. Next, the VOD list is displayed when the force press is applied to the down directional key while the home screen is being displayed.
In another embodiment, the force press may be determined as the force up when the sensing level becomes a first sensing level as the force press is applied to a specific key. The force press may be determined as the force down when the sensing level becomes a second sensing level as the force press is applied to the specific key.
That is, the input may be divided into the normal press and the force press according to the pressure applied to the key by the user. The force press may be subdivided into a plurality of sensing levels.
Hereinafter, it is assumed that the force press is subdivided to a first sensing level and a second sensing level, for convenience for description.
For example, a recommendation program may be displayed when corresponding sensing level becomes the first sensing level as the force press is applied to the determination key 140 while a home screen is being displayed. A VOD list may be displayed when the sensing level becomes the second sensing level as the force press is applied to the determination key 140.
In this case, the recommendation program may be displayed when the sensing level becomes the first sensing level as the force press is applied to the determination key 140 while the home screen is being displayed. Subsequently, a screen on which the recommendation program is displayed may be returned to the home screen when the sensing level becomes the second sensing level as the force press is applied to the determination key 140.
Subsequently, the VOD list may be displayed in the event that the second sensing level is continuously kept as the force press is applied to the determination key 140 while the home screen is being displayed. Next, a screen on which the VOD list is displayed may be returned to the home screen when the sensing level is changed to the first sensing level.
In brief, the remote controller 100 of the present embodiment determines the sensing level based on the pressure or the area applied to the key by the user and transmits the control signal including the information concerning the determined sensing level to the image processing terminal 200. The image processing terminal 200 may perform a different operation according to the sensing level, included in the received control signal, of the same key.
On the other hand, the coordinate of the key is expressed in the three dimensional coordinate (x, y, z), but it may be expressed as a four dimensional coordinate (x, y, z, t) in consideration of a time pressed to the key. That is, one or more parameters related to the sensing level may exist.
If the remote controller 100 of the invention is compared with a conventional remote controller, the conventional remote controller includes normal press only, and only one function may be matched with one key.
Accordingly, a number of keys increases whenever a function is added in the conventional remote controller. As a result, the structure of the conventional remote controller have become complicated and caused inconvenience to users.
Whereas, there may be the normal press and the force press to one key according to the sensing level in the remote controller 100. The force press may be subdivided into a plurality of sensing levels, and thus a plurality of functions may be matched with one key.
Accordingly, since a number of keys in the remote controller 100 is minimized, the remote controller 100 may have simple structure and it is convenient for the user to use the remote controller 100.
FIG. 4A is a view illustrating a sensing level according to another embodiment of the invention, and FIG. 4B is a view illustrating an operation of an image processing terminal according to the sensing level in FIG. 4A.
An input corresponding to the sensing level of the present embodiment may include a normal press, a force input and a force press.
As shown in FIG. 4A, the normal press may be the same input in the conventional remote controller. The force input refers to an input that exceeds a scope of a value of a coordinate (z) or the value of a coordinate (z) corresponding to the sensing level of the normal press as further pressure is applied to the key while the pressing or the touching to the key remains after the normal press.
Furthermore, the force press means an input that exceeds a scope of a value of a coordinate (z) or the value of a coordinate (z) corresponding to the sensing level of the force input as further pressure is applied to the key while the pressing or the touching to the key remains after the force input.
For example, as shown in FIG. 4B, when the normal press is applied to the OK key of the remote controller 100 while a cursor locates at specific contents among plural contents, the contents may be played back on a whole area of a screen.
When the force input is applied to the OK key of the remote controller 100 while the cursor locates at the specific contents, the contents may be displayed with GUI effect on the screen until before the contents is played back in PIP on a certain area of the screen as a result of the force press shown in FIG. 3B.
That is, if the input corresponding to the sensing level is divided into the normal press and the force press, the contents at which the cursor locates may be directly displayed in PIP on the certain area of the screen when the force press is applied to the OK key.
Whereas, when the force press is applied via the force input after the normal press, the contents at which the cursor locate are not directly displayed in PIP. Instead, the content at which the cursor locates among plural contents may be displayed with the GUI effect such as gradual magnification of a size of the content. The GUI effect includes a slow operation and the contents are finally played back in PIP on the certain area of the screen, as shown in FIG. 4B.
The result of the force input may be a middle operation related to the result of the force press as described in FIG. 4B or be independent operation irrespective of the result of the force press.
FIG. 5 is a view illustrating an image processing terminal according to one embodiment of the invention.
The image processing terminal 200 of the present embodiment includes a processor 210, a memory 220 connected to the processor 210 and a communication unit 230 communicating with the remote controller 100.
One or more programs are stored in the memory 220 and configured to be executed by the processor 210. The programs include instructions (commands) for operations described below.
Hereinafter, an operation of the image processing terminal 200 including the above elements will be described in detail. The input corresponding to the sensing level may be divided into the normal press and the force press.
In a step of S501, the image processing terminal 200 receives a control signal about a specific key from the remote controller 100.
In a step of S502, the image processing terminal 200 determines whether it corresponds to the normal press or the force press by verifying the sensing level of the key from the received control signal is less or more than a predetermined reference value.
In a step of S503, if it is determined that the sensing level corresponds to the normal press, the image processing terminal 200 executes a control command corresponding to the normal press of the key according to types of tasks displayed on a screen or an identifier of the key. The image processing terminal 200 displays a result of the executed control command on the screen.
In a step of S504, if it is determined that the sensing level corresponds to the force press, the image processing terminal 200 executes a control command corresponding to the force press of the key according to types of tasks displayed on a screen or the identifier of the key. The image processing terminal 200 displays a result of the executed control command on the screen.
The force press may be subdivided depending on the pressure applied to the key. The image processing terminal 200 may execute a control command corresponding to the pressure and display a result of the executed control command on the screen.
In addition to the pressure applied to the key, a time (touch time) for being applied to the key may be considered.
Accordingly, an operation of the image processing terminal 200 in response to a specific key of the remote controller 100 may be determined according to the normal press or the force press. Further, the force press may be determined according to the pressure applied to the key by the user. The operation of the image processing terminal 200 may be determined considering the time during which the key is touched or pressed.
In the event that the force input is used apart from the normal press and the force press in the sensing level, the image processing terminal 200 may further determine if it is the force input in the step of S502.
As a result, plural functions may be matched with one key, and thus the number of the key in the remote controller 100 may be minimized.
