Also, for example, if the portable device  100  is a wearable device, the display unit  120  may display an augmented reality image. That is, the portable device may provide visual information to a user by using the display unit  120 , and is not limited to the aforementioned embodiment. 
     Also, the portable device  100  may comprise the control input sensing unit  130 . At this time, the control input sensing unit  130  may be controlled by the processor  180 . The control input sensing unit  130  may deliver a user input or an environment recognized by the device to the processor  180  by using at least one sensor mounted in the portable device  100 .

The control input sensing unit  130  refers to the aforementioned various sensing means, and the aforementioned sensors may be included in the portable device  100  as separate elements or may be included in the portable device by being incorporated as at least one or more elements. Also, for example, the control input sensing unit  130  may be an element incorporated with the display unit  120 . For example, the control input sensing unit  130  may be a touch sensitive display unit  120 . That is, the processor  180  may detect an input for visual information displayed by the display unit  120  through the control input sensing unit  130 . 
     The portable device  100  may further comprise the eyes detecting unit  140  as an optional element. At this time, the eyes detecting unit  140  may be controlled by the processor  180 . For example, the eyes detecting unit  140  may detect a user&#39;s eyes. At this time, the eyes detecting unit  140  may detect whether the user looks at the portable device  100 . If the user&#39;s eyes look at the portable device  100  at a threshold time or more, the eyes detecting unit  140  may detect the user&#39;s eyes. At this time, the threshold time may be a threshold time for detecting the user&#39;s eyes, and may have a certain error range. Also, the eyes detecting unit  140  may deliver the detected eye information to the processor  180 . 
     The portable device  100  may further comprise the wearing sensor unit  150  as an optional element. At this time, the wearing sensor unit  150  may be controlled by the processor  180 .

As an embodiment, the portable device  100  may detect whether the user wears the portable device  100 , by using the proximity sensor. Alternatively, the portable device  100  may detect whether the user wears the portable device  100 , by using a sensor provided in a joint unit. That is, the portable device  100  of the present invention may determine whether the portable device  100  is worn by the user, using the aforementioned sensor units. At least one of the sensing units that provide the sensed result based on the determined will be referred to as the wearing sensor unit  150  in the present invention. 
     Also, the portable device  100  may further comprise the communication unit  160  as an optional element. The communication unit  160  may be controlled by the processor  180 . At this time, the communication unit  160  may perform communication with an external device using various protocols and thus transmit and receive data.

That is, the portable device  100  may transmit information from the external device by using the communication unit  160 . 
     Also, the portable device  100  may further comprise the status recognition information sensing unit  170  as an optional element. The status recognition information sensing unit  170  may be controlled by the processor  180 . At this time, status recognition information may be information of the status of the user or information on the state of the device. For example, the status recognition information may be position information of the user, time information, motion information or user data information. Also, the status recognition information may be information indicating whether the sensor unit within the portable device  100  is active, or information as to whether a communication network is active, or charging information of the device. That is, the status recognition information may be information on the portable device  100  and a user who uses the portable device  100 , and is not limited to the aforementioned examples. At this time, the status recognition information sensing unit  170  may be a sensor unit for sensing the status recognition information. For example, the status recognition information sensing unit  170  may be a GPS that receives position information. Also, for example, the status recognition information sensing unit  170  may be a sensor unit that detect motion of the user. Also, the status recognition information sensing unit  170  may be an audio sensing unit for sensing peripheral sound. That is, the status recognition information sensing unit  170  refers to a sensor unit that may sense information on the portable device  100  and the user, and is not limited to the aforementioned examples. 
     The processor  180  may be a unit for controlling the audio sensing unit  110 , the display unit  120  and the control input sensing unit  130 . Also, the processor  180  may be a unit for controlling at least one or more of the eyes detecting unit  140 , the wearing sensor unit  150 , the communication unit  160  and the status recognition information sensing unit  170 . In more detail, the processor  180  may detect a voice input by using the audio sensing unit  110 . For example, the voice input may include a first part for executing a first operation and a second part indicating a first execution level for the first operation. The first part may be a command language previously stored as a command language for executing the first operation. Also, the second part may be a command language previously stored as a command language indicating an execution level for the first operation. For example, the execution level for the first operation may be configured based on at least one of attribute, type, operation time and operation method of the first operation. That is, the execution level for the first operation may be a detailed command for the first operation. For example, the first operation may be an operation for making toast. At this time, for example, the first part may be a command language for “toast” and “making operation”. Also, the second part may be baking intensity of toast. For example, if the user says that “make toast at a second stage”, the first part may be “toast” and “make”. Also, the second part may be “second stage”. At this time, the processor  180  may detect a voice input by using the audio sensing unit  110 . Also, the processor  180  may execute the first operation at a first execution level on the basis of the voice input. That is, the processor  180  may make toast at the second stage. At this time, the processor  180  may execute the first operation by using the external device. In more detail, the processor  180  may transmit a first triggering signal to the external device by using the communication unit  160  on the basis of the detected voice input. At this time, the first triggering signal may be a signal for a command for executing the first operation with respect to the external device. The external device may execute the first operation on the basis of the first triggering signal. That is, the portable device  100  may control the external device in which the operation is executed, by using the communication unit  160 . For example, the processor  180  may transmit the first triggering signal to a toaster, which is the external device, on the basis of the voice input of the user. At this time, the toaster may make toast on the basis of the first triggering signal. 
     For another example, the processor  180  may detect the status recognition information by using the status recognition information sensing unit  170 . At this time, the processor  180  may executed the first operation on the basis of the status recognition information. In more detail, the processor  180  may determine whether to execute the first operation considering the status of the user or the device. Also, for example, the processor  180  may determine an execution level of the first operation considering the status of the user or the device. At this time, as described above, the status recognition information may be user or device information. For example, if time information corresponds to a.m. and position information of the user corresponds to house as the status recognition information, the processor  180  may execute toast baking, which is the first operation, on the basis of the voice input. Also, for example, if time information corresponds to p.m. and position information of the user corresponds to office as the status recognition information, the processor  180  may not execute toast baking, which is the first operation, even though the voice input is detected. That is, the processor  180  may control the first operation and the execution level of the first operation by using the information detected through the status recognition information sensing unit  180 . 
     Also, the processor  180  may detect a voice input that includes only the first part for executing the first operation. In more detail, the processor  180  may detect a voice input having no information on the execution level. For example, if the user says “make toast”, the processor  180  cannot determine a desired baking stage of the user. That is, the processor  180  cannot execute the first operation considering the execution level. At this time, for example, if the display unit  120  is activated, the processor  180  may display a first interface indicating execution level information, by using the display unit  120 . At this time, the processor  180  may detect a control input for selecting a second execution level from the first interface through the control input sensing unit  130 . At this time, the processor  180  may execute the first operation at the second execution level on the basis of the detected control input. For example, the state that the display unit  120  is activated may be a state that the portable device  100  displays visual information through the display unit. That is, the state may be an on-state of the display unit  120 . Whether the display unit  120  is activated may not be determined depending on whether a power is supplied to the display unit  120  inside the portable device  100 . That is, if the user may view visual information through the display unit  120 , the display unit  120  is activated. Also, if the user cannot view visual information through the display unit  120 , the display unit  120  is deactivated. At this time, for example, if the processor  180  detects the user&#39;s eyes through the eyes detecting unit  140 , the display unit  120  may be activated. For another example, if the portable device  100  is worn by the user through the wearing sensor unit  150 , the processor  180  may activate the display unit. This will be described with reference to  FIGS. 5 a    and  5   b.    
     Also, for example, if the display unit  120  is deactivated, the processor  180  may execute the first operation at a default level. At this time, the default level may be a default value set by the user or the processor  180 . For example, the default level may be set on the basis of the status recognition information. In more detail, the processor  180  may set an optimal condition to the default level considering the status of the user or the device. For example, if the user says “make toast”, the processor  180  may make toast at a second stage which is the default level set by the user. For another example, the processor  180  may set the first stage used most frequently by the user to the default level by using history information of the user. That is, the default level may be information on a level previously set on the basis of the status recognition information. 
     That is, if the processor  180  detects a voice input that includes only the first part for executing the first operation, the processor  180  may set a method for executing the first operation differently depending on whether the display unit is activated. At this time, if the display unit is activated, the processor  180  may control execution of the first operation through the interface. Also, if the display unit is deactivated, the processor  180  may first execute the first operation at the default level and then control the first operation. This will be described with reference to  FIGS. 5 a    and  5   b.    
     Also, the aforementioned elements may be included in the portable device  100  as separate elements, or may be included in the portable device  100  by being incorporated as at least one or more elements. 
       FIG. 2  is a view illustrating a voice recognition system in accordance with one embodiment of the present specification. The portable device  100  may be operated as one system with an external device that executes an operation. In more detail, the voice recognition system may include a first device  100  that detects a voice input and transmits a triggering signal for executing an operation on the basis of the detected voice input. At this time, the first device  100  may be the aforementioned portable device  100 . The first device  100  may be a device that detects a voice input and controls external devices  210 ,  220 ,  230  and  240 . That is, the first device  100  controls whether to execute an operation on the basis of a voice input, but may not be a device that directly executes an operation. The voice recognition system may include second devices  210 ,  220 ,  230  and  240 . The second devices  210 ,  220 ,  230  and  240  may be a single device or a plurality of devices. For example, the second devices  210 ,  220 ,  230  and  240  may be devices that execute their respective operations. That is, the second devices  210 ,  220 ,  230  and  240  may be the devices that receive a triggering signal for an operation from the first device and executes the operation on the basis of the received triggering signal, and are not limited to the aforementioned examples. Also, for example, in the voice recognition system, the first device  100  may control execution of the operation on the basis of the detected voice input. In more detail, the first device  100  may detect a first voice input that includes a first part for executing a first operation and a second part indicating a first execution level for the first operation. At this time, the first device  100  may transmit a first triggering signal to any one of the second devices  210 ,  220 ,  230  and  240  on the basis of the first voice input. The first device  100  may transmit the first triggering signal to the second device that may execute the first operation. The second devices  210 ,  220 ,  230  and  240  may receive the first triggering signal. At this time, the second devices  210 ,  220 ,  230  and  240  may execute the first operation at the first execution level on the basis of the received first triggering signal. That is, if the first device  100  detects a voice input for the first operation and a detailed execution level of the first operation, the second device may execute the operation on the basis of the triggering signal received from the first device  100 . 
     Also, the first device  100  may detect a second voice input that includes only a first part for executing the first operation. That is, the second voice input may not include information on the execution level of the first operation. At this time, if the display unit of the first device  100  is in an activated state, the first device  100  may display a first interface for the execution level of the first operation. At this time, the first device  100  may detect a control input for a second execution level from the first interface. The first device  100  may transmit a second triggering signal to the second devices  210 ,  220 ,  230  and  240  on the basis of the control input. At this time, the second devices  210 ,  220 ,  230  and  240  may execute the first operation at the second execution level on the basis of the second triggering signal. That is, the first device  100  may control the display unit by displaying information on an execution level if the display unit is in an activated state. For another example, if the display unit of the first device  100  is in a deactivated state, the first device  100  may transmit a third triggering signal to the second devices  210 ,  220 ,  230  and  240 . At this time, the third triggering signal may be a signal for executing the first operation at a default level. The second devices  210 ,  220 ,  230  and  240  may execute the first operation at the default level on the basis of the third triggering signal. That is, the first device  100  may control the display unit to execute the first operation at the default level if the display unit is in a deactivated state. Hereinafter, in this specification, a device that executes an operation by detecting a voice input will be described based on the portable device, and may equally be applied to the voice recognition system. 
       FIGS. 3 a  and 3 b    are views illustrating a method for executing an operation on the basis of a voice input in a portable device in accordance with one embodiment of the present specification. The portable device  100  may detect a voice input. At this time, if a command language previously set in the portable device  100  is included in the voice input, the portable device  100  may execute an operation on the basis of the voice input. For example, the portable device  100  may transmit a triggering signal to an external device  320 , and may execute the operation using the external device  320  as described above. The portable device  100  may detect a first voice input that includes a first part for executing a first operation and a second part indicating a first execution level for the first operation. That is, the portable device  100  may detect the first voice input that includes a detailed control operation of the first operation. At this time, the portable device  100  may execute the first operation at the first execution level. For example, the portable device  100  may execute the first operation at the first execution level regardless of the fact whether the display unit  120  is activated. That is, the portable device  100  may execute a detailed operation on the basis of a detailed voice input. 
     For example, referring to  FIGS. 3 a  and 3 b   , the portable device  100  may detect a voice input of “make toast at a second stage”. At this time, the first part may be “toast” and “make”. Also, the second part may be “second stage”. The portable device  100  may make toast at a second stage using a toaster  320  which is an external device. At this time, for example, the portable device  100  may display information on the first operation. 
       FIGS. 4 a  and 4 b    are views illustrating a method for executing an operation on the basis of a voice input in a portable device in a state that a display unit is activated in accordance with one embodiment of the present specification. The portable device  100  may detect a second voice input that includes only a first part for executing a first operation. That is, a user  310  may not perform a command for a detailed operation for an operation. At this time, for example, the display unit  120  of the portable device may be in an activated state. If the display unit  120  provides visual information to the user as described above, the display unit  120  may be in an activated state. That is, the state that the user may view the visual information through the display unit  120  may be in the activated state. At this time, the portable device  100  may display a first interface  410  indicating an execution level for the first operation on the basis of the second voice input. That is, since the user  310  views the portable device  100 , the portable device  100  may provide information on the first operation. At this time, the portable device  100  may detect a control input of a user who selects the first execution level. Also, the portable device  100  may detect a control input of a user who executes the first operation. At this time, the portable device  100  may transmit a triggering signal to the external device  320 . The external device  320  may execute the first operation at the selected first execution level on the basis of the triggering signal. That is, if the display unit  120  is in an activated state, the portable device  100  may execute the first operation under the control of the user. 
       FIGS. 5 a  and 5 b    are views illustrating a method for executing an operation on the basis of a voice input in a portable device in a state that a display unit is deactivated in accordance with one embodiment of the present specification. The portable device  100  may detect a second voice input that includes only a first part for executing a first operation. At this time, for example, the display unit  120  of the portable device  100  may be in a deactivated state. For example, the deactivated state may be the state that the portable device  100  does not provide visual information. For another example, the deactivated state may be the state that a user&#39;s eyes are not detected. In more detail, the portable device  100  may detect the user&#39;s eyes using the eyes detecting unit  140 . At this time, if the user&#39;s eyes are not detected, the portable device  100  may detect the deactivated state. For another example, if the user&#39;s eyes are not detected for a threshold time or more, the portable device  100  may detect the deactivated state. At this time, the threshold time may have a certain error. 
     If the portable device  100  detects the second voice input in the deactivated state, the portable device  100  may execute the first operation at the default level. In more detail, if the user does not view the portable device  100  or does not use the portable device  100 , the portable device  100  cannot be controlled by the user. Therefore, the portable device  100  may first execute the first operation at a default level on the basis of the second voice input. At this time, the default level may be a basic value  200  previously set by the user or the processor. For another example, the default level may be a value set based on status recognition information of the user or the device. For example, the default level may be a value having the highest frequency based on history information on a usage record of the user. That is, the default level may be a value that may be set in a state that there is no input of the user. If the portable device  100  detects the second voice input, the portable device may transmit a triggering signal to the external device  320 . The external device  320  may execute the first operation at the default level on the basis of the triggering signal. As a result, the user may simply execute the operation even without a detailed control command or operation. 
       FIGS. 6 a  and 6 b    are views illustrating a method for enabling a portable device to activate a display unit in accordance with one embodiment of the present specification. The portable device  100  may execute a first operation at a default level in a state that the display unit is deactivated. At this time, the portable device  100  may detect that the display unit is switched from the deactivated state to the activated state. At this time, the portable device  100  may further display a first interface  410 . 
     For example, referring to  FIG. 6 a   , if the portable device  100  detects a user&#39;s eyes using the eyes detecting unit  140 , the portable device  100  may switch the display unit  120  from the deactivated state to the activated state. At this time, for example, if the user&#39;s eyes are detected for a threshold time or more, the portable device  100  may switch the display unit  120  from the deactivated state to the activated state. That is, if the user is switched to the state that the user views the portable device  100 , the portable device  100  may activate the display unit  120 . 
     For another example, referring to  FIG. 6 b   , the portable device  100  may be a wearable device. At this time, the portable device  100  may detect whether the user wears the portable device, through the wearing sensor unit  150 . At this time, if it is detected that the portable device  100  is worn by the user, the portable device  100  may switch the display unit  120  from the deactivated state to the activated state. That is, the portable device  100  may determine whether the display unit  120  is activated, depending on whether the user wears the portable device  100 . 
     Also, the portable device  100  may switch the display unit  120  to the activated state in various manners, and is not limited to the aforementioned examples. 
       FIG. 7  is a view illustrating a method for enabling a portable device to display an interface indicating information on an operation in accordance with one embodiment of the present specification. 
     The portable device  100  may detect that the display unit is switched from the deactivated state to the activated state. At this time, the portable device  100  may further display the first interface  410 . That is, the portable device  100  first executes the first operation at the deactivated state of the display unit and then display information on the first operation if the display unit is activated. At this time, the portable device  100  may further display a first indicator  710  from the first interface  410  which is displayed. At this time, the first indicator  710  may be an indicator for controlling an execution level for the first operation. At this time, the portable device  100  may detect a control input for the first indicator  710 . At this time, the portable device  100  may control the execution level for the first operation on the basis of the control input for the first indicator  710 . Also, for example, the portable device may further display a second interface  720 . At this time, the second interface  720  may be execution information on the first operation in a state that the display unit  120  is deactivated. In more detail, the portable device  100  may execute the first operation at a default level in a state that the display unit  120  is deactivated. At this time, the user may identify the execution information of the first operation for a time when the display unit  120  is deactivated. Therefore, the portable device may display the second interface  720  indicating the execution information of the first operation if the display unit  120  is switched to the activated state. For example, the second interface  720  may include information on operation time when the first operation is executed, progress information of the first operation, and information as to whether execution of the first operation is completed. That is, the second interface  720  may indicate the information of the first operation in a state that the display unit  120  is deactivated, and is not limited to the aforementioned examples. For another example, the portable device  100  may execute the first operation at the default level and end execution of the first operation if the display unit  120  is not activated within a first threshold time. At this time, the first threshold time may have a certain error. That is, the portable device  100  may end the first operation after the passage of a certain time even without the control operation of the user if the display unit is not activated. As a result, the user may directly control execution and termination of the first operation. 
       FIGS. 8 a  and 8 b    are views illustrating a method for enabling a portable device to provide a feedback on the basis of a voice input in accordance with one embodiment of the present specification. If the portable device  100  executes a first operation at a default level, the portable device  100  may provide a feedback for the first operation. At this time, the feedback may include at least one of visual feedback, audio feedback, and tactile feedback. That is, the feedback may be information provided to the user, and is not limited to the aforementioned examples. 
     For example, referring to  FIG. 8 a   , the feedback may be audio feedback. At this time, the portable device  100  may provide whether the first operation is executed, through the feedback. For example, the first operation may be an operation for making toast. At this time, the portable device  100  may provide a user with an audio feedback indicating that “toast is made at a first stage (default level)”. As a result, the user may identify whether the first operation is executed, even in a state that the display unit  120  is not activated. 
     For another example, referring to  FIG. 8 b   , the portable device  100  may provide a feedback for an execution level of the first operation. At this time, the portable device  100  may detect a voice input, which includes information on a second execution level, on the basis of the feedback. At this time, the portable device  100  may execute the first operation at the second execution level. For example, the first operation may be an operation for making toast. At this time, the portable device  100  may provide the user with a feedback indicating that “what stage do you want to make toast?”. At this time, the portable device  100  may detect a voice input of the user, which indicates “second stage”. The voice input may be information on the execution level of the first operation. At this time, the portable device  100  may make toast at the second stage. That is, the portable device  100  may execute the first operation considering the execution level. As a result, the user may execute the operation even in a state that the display unit  120  is not activated. 
       FIG. 9  is a view illustrating a method for enabling a portable device to execute an operation on the basis of a voice input in accordance with one embodiment of the present specification. The portable device  100  may detect a voice input and execute an operation on the basis of the detected voice input. At this time, the portable device  100  may detect a voice input on the basis of an operation standby mode. In more detail, if the portable device always detects a voice input, the portable device may execute an operation on the basis of a voice input which is not intended by a user. Therefore, the portable device  100  needs to execute an operation with respect to only a voice input intended by the user. For example, the portable device  100  may detect a third voice input and set an operation standby mode on the basis of the detected third voice input. At this time, for example, the third voice input may be a command language for executing a previously set command language or the operation standby mode. Also, the operation standby mode may be a standby state that the portable device  100  executes the operation. That is, the portable device  100  may execute the operation on the basis of the voice input only in the operation standby state. 
     For example, referring to  FIG. 9 , the portable device  100  may detect a voice input indicating “K, make toast”. At this time, the portable device  100  may execute the operation using the toaster  320  which is an external device. Also, the portable device  100  may detect a voice input indicating “make toast”. At this time, the portable device  100  may not execute the operation using the toaster  320  which is an external device. That is, the portable device  100  may execute the operation only if the portable device  100  detects a command language for the operation after detecting a command language indicating “K” for executing the operation standby mode. As a result, the user may prevent the operation from being executed based on an unwanted voice input. 
       FIG. 10  is a view illustrating status recognition information detected by a portable device in accordance with one embodiment of the present specification. The portable device  100  may detect status recognition information by using the status recognition information sensing unit  170 . Also, the portable device  100  may execute an operation on the basis of the detected status recognition information. For example, the status recognition information may be state information of the user or the device. Also, for example, the status recognition information sensing unit  170  may be an audio sensing unit  110  that detects voice information. For another example, the status recognition information may be information based on big data. For example, the portable device  100  may receive big data information on the user or the device through the communication unit  160 . At this time, the big data information may include lifestyle information of the user, history information on operation execution, operation executable device information, etc. That is, the status recognition information is information that may be used by the portable device  100 , and may be information that may identify a surrounding environment and is not limited to the aforementioned example. 
     For example, referring to  FIG. 10 , the status recognition information may include at least one of position information of a user, time information, motion information of a user, and user data information. Also, the status recognition information may include at least one of activity information of the sensor unit, communication network information, and charging information of the device, as information on the device. At this time, if the detected status recognition information satisfies a first setup value, the portable device  100  may control whether to execute a first operation, on the basis of surrounding status information. For example, the first operation may be an operation for making toast. At this time, the portable device  100  may execute the first operation on the basis of the status recognition information. For example, the portable device  100  may execute the first operation on the basis of a voice input only if the user is located in his/her house and time is in a time range previously set to the user&#39;s attending time to work. That is, the portable device  100  may execute the first operation in case of only a specific condition on the basis of the status recognition information. Also, for example, the portable device  100  may set a default level of the first operation on the basis of the status recognition information. For example, the portable device  100  may set a level executed most frequently among execution levels of the first operation to the default level on the basis of history information. That is, the portable device  100  may set whether the first operation is executed or the default level of the first operation, on the basis of the status recognition information, and is not limited to the aforementioned examples. 
       FIG. 11  is a view illustrating a control method for a portable device in accordance with one embodiment of the present specification. The portable device  100  may detect a voice input (S 1110 ). At this time, as described in  FIG. 1 , the portable device  100  may detect the voice input by using the audio sensing unit  110 . 
     Next, the portable device  100  may detect whether a first part for executing a first operation is included in the detected voice input (S 1120 ). At this time, as described in  FIG. 1 , the first part may be a part for executing the first operation. At this time, the first part may be a part previously set by the user or the processor  180 . At this time, the portable device  100  may execute the first operation if the previously set first part is included in the voice input. 
     Next, the portable device  100  may detect whether a second part indicating a first execution level for the first operation is included in the detected voice input (S 1130 ). At this time, as described in  FIG. 1 , the second part may be a part for indicating the first execution level of the first operation. In more detail, the second part may be a detailed command part for the first operation. 
     Next, if the second part indicating the first execution level is included in the voice input, the portable device  100  may execute the first operation at the first execution level (S 1140 ). At this time, as described in  FIGS. 3 a  and 3 b   , if the portable device  100  detects a voice input for an operation and a detailed execution level for the operation, the portable device  100  may execute the operation on the basis of the voice input. At this time, the portable device  100  may execute the operation regardless of the fact that the display unit is activated. That is, if the portable device  100  detects the part for the first execution level which is a detailed command for the first operation, the portable device  100  may execute the first operation at the first execution level. 
     Next, if the second part indicating the first execution level is not included in the voice input, the portable device  100  may detect whether the display unit is activated (S 1150 ). At this time, as described in  FIG. 1 , the portable device  100  may detect whether the display unit  120  is activated, through the eyes detecting unit  140 . Also, if the portable device  100  is a wearable device, the portable device  100  may detect whether the display unit  120  is activated, through the wearing sensor unit  150 . 
       FIG. 12  is a view illustrating a control method for a portable device in accordance with one embodiment of the present specification. The portable device  100  may detect whether the display unit is activated (S 1210 ). At this time, as described in  FIG. 1 , the activated state of the display unit  120  may be the state that the portable device  100  may provide a user with visual information. That is, the state that the user may view the visual information through the portable device  100  may be the state that the display unit  120  is activated. 
     Next, if the portable device  100  is in an activated state, the portable device  100  may display a first interface indicating an execution level of a first operation (S 1220 ). At this time, as described in  FIG. 7 , the first interface may be an interface indicating a detailed execution method of the first operation. At this time, the first interface may include a first indicator. The first indicator may be an indicator for controlling an execution level of the first operation. The portable device  100  may control the execution level of the first operation on the basis of a control input for the first indicator. 
     Next, the portable device  100  may detect a control input for selecting a second execution level from the first interface (S 1230 ). At this time, as described in  FIG. 1 , the portable device  100  may detect a control input for selecting the second execution level by using the control input sensing unit  130 . That is, since the display unit  120  is activated, the portable device  100  may set a detailed execution level by displaying a control interface for the first operation. 
     Next, the portable device  100  may execute the first operation at the second execution level on the basis of the detected control input (S 1240 ). At this time, as described in  FIG. 1 , the portable device  100  may transmit a triggering signal to the external device on the basis of the voice input. At this time, the external device may execute the first operation at the second execution level on the basis of the received triggering signal. That is, the portable device  100  may be a control device for executing the first operation. At this time, the external device may be a device for executing the first operation by means of the portable device  100 . 
     Next, if the portable device  100  is in an deactivated state, the portable device  100  may execute the first operation at a default level (S 1250 ). At this time, as described in  FIG. 1 , since the display unit  120  is activated, the portable device  100  may first execute the first operation. At this time, the default level may be a value previously set by the user or the processor  180 . Also, the default level may be a value set on the basis of the status recognition information. At this time, the portable device  100  cannot provide the user with an interface for the first operation as the display unit  120  is deactivated. Therefore, the portable device  100  may first execute the first operation at the default level. At this time, if the display unit is switched from the deactivated state to the activated state, the portable device  100  may further display the first interface. 
     For another example, if the portable device  100  executes the first operation at the default level, the portable device  100  may provide a feedback for the first operation. At this time, the feedback may include at least one of visual feedback, audio feedback and tactile feedback. 
     Moreover, for convenience of description, although the description has been made for each of the drawings, the embodiments of the respective drawings may be incorporated to achieve a new embodiment.
