However, the configurations and functions illustrated in the following exemplary embodiments are not construed as limiting the present inventive concept and the key configurations and functions. In the following descriptions, details about publicly known functions or features will be omitted if it is determined that they cloud the gist of the present inventive concept.
In the following exemplary embodiments, terms ‘first’, ‘second’, etc. are only used to distinguish one element from another, and singular forms are intended to include plural forms unless otherwise mentioned contextually.

Further, according to an embodiment of the disclosure, another touch input may be possible besides the ‘first touch input’ made with regard to each of the plurality of touch positions 101˜107. For example, as shown in
Like this, the electronic apparatus 100 according to an embodiment of the disclosure carries out the operation corresponding to each of the touch positions 101˜107 when the first touch input is received, and carries out the operation corresponding to the motion of the second touch input when the second touch input is received.
Meanwhile, the first touch input and the second touch input as described above are merely an example, and there are no limits to the touch input possible that can be made with regard to the electronic apparatus 100 of the disclosure. Another example of the touch input and corresponding operations of the electronic apparatus will be described later in detail.
The touch input portion 201 has the touch area 200 for receiving the touch input. The touch input portion 201 may be configured with a pressure sensor or a touch sensor of a capacitive overlay type, a resistive overlay type, an infrared beam type, etc. However, the touch input portion 201 may be actualized by any kind of sensor capable of sensing contact or pressure of an object without limitation. The touch input portion 201 generates a reception signal when a user's touch input is received, and transmits the reception signal to the controller 202.
The plurality of touch positions are designated within the touch area 200 of the touch input portion 201. When a user touches a certain position among the plurality of touch positions, the touch input portion 201 detects where a user touches the touch area 200. This may be achieved by individual touch sensors respectively provided at the touch positions, or may be achieved by using a single touch sensor or fewer touch sensors than the number of touch positions and utilizing information for identifying each touch position. Further, each touch position may, but does not necessarily, be set to correspond to an operation of the electronic apparatus to be carried out when the corresponding touch position is touched. Below, for convenience of description, it will be described on the assumption that the individual touch sensors are respectively provided at the touch positions, and each touch position is set to correspond to the operation of the electronic apparatus to be carried out when the corresponding touch position is touched.
The controller 202 controls general operations of elements such as the touch input portion 201 in the electronic apparatus 100. The controller 202 controls the touch input portion 201 to receive a user's touch input, and recognizes the kind or the like of the touch input received through the touch input portion 201.
The controller 202 may include a nonvolatile memory in which a control program is stored, a volatile memory into which at least a part of the control program is loaded, and a microprocessor for executing the control program. Further, the controller 202 may include two or more microprocessors. For example, the controller 202 may include a main processor for performing main control such as control operations of the controller 202, and an auxiliary processor for performing sub control such as power control, input/output control, etc.

Even when the electronic apparatus 100 of the disclosure is the smart phone 302, as shown in
Referring back to
In the disclosure, various touch inputs are possible as well as the first touch input.
Like this, according to the disclosure, it is possible to support various touch inputs, and thus have an effect as if the touch sensors individually operating at separate positions serve as a single touch pad. Further, according to the disclosure, more various touch input methods are used to control the electronic apparatus 100, and it is thus more convenient for a user to control the electronic apparatus 100.
First, the controller 202 controls the touch input portion 201 to receive a user's touch input. The touch input portion 201 receives a user's touch input (S701) and generates a reception signal, thereby transmitting the reception signal to the controller 202.
The controller 202 identifies whether the received touch input is the first touch input or the second touch input. When the received touch input is the first touch input, the controller 202 identifies a touch position where the first touch input is made (S702), and controls the electronic apparatus 100 to carry out an operation corresponding to the touch position (S703). When the received touch input is the second touch input, the controller 202 identifies the motion of the second touch input, i.e. the motion that moves from the first touch position to the second touch position (S704), and controls the electronic apparatus 100 to carry out an operation corresponding to the motion of the second touch input (S705).
For convenience of description,
Referring back to
The signal receiver 203 receives a broadcast signal. The signal receiver 203 may receive a broadcast signal from a broadcast signal transmitter of a broadcasting station, or may receive a broadcast signal from a relay apparatus that relays the broadcast signal. The broadcast signal received in the signal receiver 203 may be a wired or wireless signal, a digital or analog signal, a skywave signal, a cable signal, a satellite signal, or a network signal. Further, the signal receiver 203 may additionally include a Wi-Fi communication module for wireless communication, an Ethernet module for separate wired connection, a universal serial bus (USB) port for connection with a USB memory.
The signal receiver 203 may receive a broadcast signal of a certain channel among a plurality of channels under control of the controller 202. The broadcast signal contains broadcast content provided by the broadcasting station. The broadcast content includes various broadcast programs such as drama, movie, news, sports, music, video on demand (VOD), etc. and there are no limits to the content.
The signal processor 204 processes a broadcast signal received in the signal receiver 203. Under control of the controller 202, the signal processor 204 performs a signal process according to the formats of the received broadcast signal and extracts data of broadcast content.
There are no limits to the kind of image processing process performed in the signal processor 204. The image process performed in the signal processor 204 may for example include de-multiplexing for dividing an input stream into sub streams such as video, audio and appended data; decoding corresponding to a video format of a video stream; de-interlacing for converting an interlaced type of a video stream into a progressive type; scaling for adjusting a video stream to have a preset resolution; noise reduction for improving image quality; detail enhancement; frame refresh rate conversion; etc.
The display 205 may display an image based on data of broadcast content extracted by the signal processor 204. There are no limits to the type of the display 205. For example, the display 205 may be actualized by various types such as liquid crystal, plasma, a light emitting diode, an organic light-emitting diode, a surface-conduction electron-emitter, a carbon nano-tube, nano-crystal, etc.
The display 205 may include an additional element in accordance with its types. For example, in a case of the liquid crystal type, the display 205 may include a liquid crystal display panel, a backlight unit for emitting light to the liquid crystal display panel, a panel driving substrate for driving the liquid crystal display panel, etc.
When the electronic apparatus 100 of the disclosure further includes the display 205 as described above, the touch input portion 201 may be arranged around the display 205.
Below, operations of the electronic apparatus 100 having the foregoing configuration and using the foregoing touch input method according to an embodiment of the disclosure will be described by providing concrete examples. It will be described on the assumption that the electronic apparatus 100 is a TV, and the TV includes all the elements shown in
Operations of when the touch inputs of various methods are received in the electronic apparatus 100 will be described below in sequence. First, when the first touch input is received, i.e. when a user's first touch input is made with regard to a certain touch position among the plurality of designated touch positions 101˜107, the operation of the electronic apparatus 100 is carried out corresponding to the touch position. For example, when a user touches the touch position 105, the operation of changing the channel up one step is carried out.
The operation in the case of receiving the second touch input will be described with reference to
It may be determined by the first touch position whether to control the channel jumping-over degree or the volume in response to the speed of the second touch input. That is, in the case of
The speed of the second touch input may be varied depending on a distance between the touch positions through which the second touch input passes, and time at which the first touch position and the second touch position are touched. For example, on the assumption that the touch positions are all arranged as equidistantly spaced apart from each other, the speed of the second touch input may be determined based on a value obtained by dividing the number of spaces between the first touch position and the second touch position by time taken in moving the touch from the first touch position to the second touch position. Further, the channel jumping-over degree may be determined corresponding to the speed of the second touch input on the basis of a table where the channel jumping-over degrees are tabulated matching the speeds of the second touch input.
To simplify the method of determining the adjustment degree, the adjustment degree may be determined based on the number of spaces via which the second touch input moves. Such examples are depicted in
When the third touch input is received, the operation of the electronic apparatus 100 may include various operations corresponding to the third touch input. For example, when the third touch input is received, a ‘previous operation cancel’ operation may be carried out. In more detail, for example, as shown in
When the fourth touch input is received, the operation of the electronic apparatus 100 may also include various operations corresponding to the fourth touch input. Because the fourth touch input corresponds to an operation of moving to the second touch position from touch with ‘plural’ points of the first touch position, a user can use many fingers to make the fourth touch input like the second touch input. Accordingly, a matching operation may be similar to the operation corresponding to the second touch input but different in that its adjustment degree is multiplied in accordance with the number of used fingers. For example, when the motion of the second touch input shown in
According to an embodiment of the disclosure, an operation or interface of the electronic apparatus 100 corresponding to a plurality of touch positions designated within the touch input portion 201 may be newly configured to support various touch input methods.
In this case, it is enough to show that the first touch position is related to the ‘volume’, and there are no needs to set the touch positions respectively corresponding to ‘volume up’ and ‘volume down’. Therefore, as shown in
A detailed configuration and operations of the electronic apparatus 100 for controlling at least one of the channel jumping-over degree and the volume in response to the speed of the second touch input are as follows.
The touch sensor 1201 senses a user's touch input to a plurality of designated touch positions of the touch input portion 201.
The touch time counter 1202 counts time of a user's touch sensed by the touch sensor 1201 from the start of the touch to the finish of the touch.
The calculator 1203 calculates the speed of the second touch input based on the time of the touch input and a moving distance of the touch. The time of the touch input is obtained based on the time counted by the touch time counter 1202, and the moving distance of the touch is obtained based on the start and finish points of the touch input sensed by the touch sensor 1201.
The calculator 1203 determines the operation of the electronic apparatus 100 based on the speed of the second touch input calculated as above. Of course, the operation may be also determined through the lookup table as shown in
The processor 1204 actually carries out and processes the operation of the electronic apparatus 100 determined in the calculator 1203.
When a user's touch input starts, the touch sensor 1201 senses a touch position at which the user's touch input starts (S1301). The touch time counter 1202 starts counting time (S1302).
All the second to fourth touch inputs except the first touch input are moved to another touch position after touching the start touch position. Therefore, the touch sensor 1201 is on standby to sense whether a touch signal is input to another touch position even when a user's touch input is sensed at one touch position (S1303). With this, it is possible to determine whether a user's touch position is moved (S1304).
When the touch signal is not input to another touch position, i.e. when a user's touch position is not moved, this corresponds to the first touch input, i.e. one touch of a certain touch position, and therefore the processor 1204 directly carries out the operation of the electronic apparatus 100 in response to the corresponding touch position.
On the other hand, when the touch position moves, the touch sensor 1201 senses the moved touch position and the touch-finished touch position (S1305). Further, the touch time counter 1202 stops counting in time for the touch finish (S1306).
Then, the calculator 1203 calculates the speed of the second touch input based on the start and finish touch positions sensed by the touch sensor 1201, and touch time counted by the touch time counter 1202 (S1307), and determines the corresponding operation of the electronic apparatus 100 (S1308).
The processor 1204 actually carries out and processes the operation of the electronic apparatus 100 determined as above (S1309).
Although the detailed configuration and operations of the electronic apparatus 100 for controlling at least one of the channel jumping-over degree and the volume in response to the speed of the second touch input are described with reference to
Below, another embodiment of the disclosure will be described. As an alternative to the foregoing embodiments, the electronic apparatus 100 according to this embodiment of the disclosure is related to a smart phone.
The touch screen 1406 is installed on the surface of the display 1405 and senses a user's touch input to the display 1405. The touch screen 1406 may be configured with a pressure sensor or a touch sensor of a capacitive overlay type, a resistive overlay type, an infrared beam type, etc. However, the touch screen 1406 may be actualized by any kind of sensor capable of sensing contact or pressure of an object without limitation. The touch screen 1406 generates a reception signal when a user's touch input is received, and transmits the reception signal to the controller 1402.
The touch screen 1406 is a separate element from the touch input portion 1401, and receives a fifth touch input different from the first to fourth touch inputs receivable in the touch input portion 1401. The fifth touch input may include various touch input to a touch screen, for example, a tap, a double tap, drag, drag and drop, a pinch zoom in/out, multi-touch drag for rotating a screen, etc. The touch screen 1406 may display a UI for receiving the foregoing fifth touch input.
The touch input using both the touch screen 1406 and the touch input portion 1401 is also possible. That is, the electronic apparatus 100 according to another embodiment of the disclosure may be controlled by making one of the first to fourth touch inputs to the touch input portion 1401 while the fifth touch input is made on the touch screen 1406.
As above, the touch input using both the touch screen 1406 and the touch input portion 1401 is utilizable in various jobs. For example, in a case where a moving picture is being played back in the smart phone and it is possible to control a sound at a specific point of the played screen to be distinguishable from a sound at a different point because the moving picture is recorded and generated using multi-microphones, when a user makes the second touch input of turning the volume up with one hand on the touch input portion 1401 while touching the first point 1501 of the touch screen 1406 with the other hand, it is possible to turn up only the volume of the sound at the point corresponding to the first point 1501 on a moving picture screen.
Like this, when the touch input using both the touch screen 1406 and the touch input portion 1401 is utilized, various inputs, which are impossible or difficult for the touch input using only the touch screen 1406 or the touch input using only the touch input portion 1401, are allowed, thereby controlling the electronic apparatus 100 through more various methods.
Although the disclosure has been described by the limited embodiments and drawings, various modifications and changes can be made from the foregoing descriptions by a person having an ordinary skill in the art. For example, proper results are achieved even though the described features are carried out in order different from that of the foregoing method, or the elements of the described system, structure, apparatus, circuit, etc. may be coupled or assembled in a form different from that of the foregoing method, or may be replaced or substituted by other elements or equivalents. Accordingly, the disclosure is not restricted by the foregoing embodiments and accompanying drawings, but involves other actualizations, embodiments, appended claims and equivalents, and the methods of the disclosure are taken into account for not restrictive but illustrative purpose.
