The portable device includes sensors configured to sense user inputs; a sensor hub configured to activate a main processor and control the sensors including a touch sensor, the touch sensor sensing touch inputs while the portable device is in a standby mode; and the main processor configured to execute an application and control the portable device, wherein, when the portable device is in the standby mode, the touch sensor is in an active state and at least one of the sensors except the touch sensor is in an inactive state, and when the touch sensor detects a first touch input which corresponds to a pre-stored pattern, the sensor hub activates the main processor and switches the portable device from the standby mode to an active mode. ## Claims ### Claim 1 A portable device comprising: sensors configured to sense user inputs; a sensor hub configured to activate a main processor and control the sensors including a touch sensor, the touch sensor sensing touch inputs while the portable device is in a standby mode; and the main processor configured to execute an application and control the portable device, wherein, when the portable device is in the standby mode, the touch sensor is in an active state and at least one of the sensors except the touch sensor is in an inactive state, and when the touch sensor detects a first touch input which corresponds to a pre-stored pattern, the sensor hub activates the main processor and switches the portable device from the standby mode to an active mode. ### Claim 2 (depends on 1) The portable device according to claim 1, wherein the first touch input is a knock gesture to the portable device. ### Claim 3 (depends on 1) The portable device according to claim 1, wherein when the portable device is switched from the standby mode to the active mode, the at least one of the sensors is switched to the active state. ### Claim 4 (depends on 1) The portable device according to claim 1, wherein when the portable device is in the standby mode, the main processor is in the inactive state and the sensor hub is in the active state. ### Claim 5 (depends on 1) The portable device according to claim 1, wherein the portable device further comprises a display unit. ### Claim 6 (depends on 5) The portable device according to claim 5, wherein when the portable device enters the active mode, the display unit is configured to provide a feedback indicating that the portable device is entered into the active mode. ### Claim 7 (depends on 1) The portable device according to claim 1, wherein when the touch sensor detects a second touch input which does not correspond to the pre-stored pattern, the sensor hub does not activate the main processor and maintain the portable device in the standby mode. ### Claim 8 (depends on 1) The portable device according to claim 1, wherein when the touch sensor detects the first touch input, the sensor hub determines whether the first touch input corresponds to the pre-stored pattern to activate the main processor. ### Claim 9 (depends on 1) The portable device according to claim 1, wherein the sensors include at least two of a gravity sensor, a geomagnetic sensor, a gyro sensor, an acceleration sensor, an inclination sensor, an illuminance sensor, an altitude sensor, an odor sensor, a temperature sensor, a depth sensor, a pressure sensor, a bending sensor, an audio sensor, a video sensor, a Global Positioning System (GPS) sensor, the touch sensor and a mechanical vibration sensor. ### Claim 10 (depends on 1) The portable device according to claim 1, wherein the sensor hub is connected to entire of the sensors. ### Claim 11 A method of controlling a portable devices, the method comprising: activating a touch sensor when the portable device is in a standby mode, wherein the portable device includes sensors and at least one of the sensors except the touch sensor is in an inactive state; detecting, through the touch sensor, a first touch input; determining, through a sensor hub, whether the first touch input corresponds to a pre-stored pattern to activate a main processor; activating, through the sensor hub, the main processor when the first touch input corresponds to the pre-stored pattern; and switching the portable device from the standby mode to an active mode. ### Claim 12 (depends on 11) The method according to claim 11, wherein the first touch input is a knock gesture to the portable device. ### Claim 13 (depends on 11) The method according to claim 11, wherein when the portable device is switched from the standby mode to the active mode, the at least one of the sensors is switched to the active state. ### Claim 14 (depends on 11) The method according to claim 11, wherein when the portable device is in the standby mode, the main processor is in the inactive state and the sensor hub is in the active state. ### Claim 15 (depends on 11) The method according to claim 11, wherein the portable device further comprises a display unit. ### Claim 16 (depends on 15) The method according to claim 15, wherein when the portable device enters the active mode, the display unit is configured to provide a feedback indicating that the portable device is entered into the active mode. ### Claim 17 (depends on 11) The method according to claim 11, wherein when the touch sensor detects a second touch input which does not correspond to the pre-stored pattern, the sensor hub does not activate the main processor and maintain the portable device in the standby mode. ### Claim 18 (depends on 11) The method according to claim 11, wherein when the touch sensor detects the first touch input, the sensor hub determines whether the first touch input corresponds to the pre-stored pattern to activate the main processor. ### Claim 19 (depends on 11) The method according to claim 11, wherein the sensors include at least two of a gravity sensor, a geomagnetic sensor, a gyro sensor, an acceleration sensor, an inclination sensor, an illuminance sensor, an altitude sensor, an odor sensor, a temperature sensor, a depth sensor, a pressure sensor, a bending sensor, an audio sensor, a video sensor, a Global Positioning System (GPS) sensor, the touch sensor and a mechanical vibration sensor. ### Claim 20 (depends on 11) The method according to claim 11, wherein the sensor hub is connected to entire of the sensors.
