20130110521 | EXTRACTION AND ANALYSIS OF AUDIO FEATURE DATA | 05-02-2013 |
20130182858 | AUGMENTED REALITY WITH SOUND AND GEOMETRIC ANALYSIS - A method for responding in an augmented reality (AR) application of a mobile device to an external sound is disclosed. The mobile device detects a target. A virtual object is initiated in the AR application. Further, the external sound is received, by at least one sound sensor of the mobile device, from a sound source. Geometric information between the sound source and the target is determined, and at least one response for the virtual object to perform in the AR application is generated based on the geometric information. | 07-18-2013 |
20130252597 | CONTROLLING APPLICATIONS IN MOBILE DEVICE BASED ON ENVIRONMENTAL CONTEXT - A method for controlling an application in a mobile device is disclosed. The method includes receiving environmental information, inferring an environmental context from the environmental information, and controlling activation of the application based on a set of reference models associated with the inferred environmental context. In addition, the method may include receiving a sound input, extracting a sound feature from the sound input, transmitting the sound feature to a server configured to group a plurality of mobile devices into at least one similar context group, and receiving, from the server, information on a leader device or a non-leader device and the at least one similar context group. | 09-26-2013 |
20140108780 | WIRELESS COMMUNICATIONS USING A SOUND SIGNAL - A method for communicating messages by a mobile device via a sound medium is disclosed. The mobile device receives input sounds from at least one mobile device via the sound medium. From the input sounds, an input sound signal carrying a first message encoded with a first key is detected. The mobile device decodes the first message based on a matching key. An output sound signal carrying a second message encoded with a second key is generated. Further, the mobile device transmits an output sound corresponding to the output sound signal via the sound medium. | 04-17-2014 |
20140253326 | Emergency Handling System Using Informative Alarm Sound - A method includes receiving an alarm sound including information related to an emergency event. The method also includes transmitting, to a server, identification information of the mobile device and the information. The method further includes receiving, from the server, an instruction for responding to the emergency event. The method further includes outputting the instruction. | 09-11-2014 |
20140334645 | METHOD AND APPARATUS FOR CONTROLLING VOICE ACTIVATION - A method for controlling voice activation by a target keyword in a mobile device is disclosed. The method includes receiving an input sound stream. When the input sound stream indicates speech, the voice activation unit is activated to detect the target keyword and at least one sound feature is extracted from the input sound stream. Further, the method includes deactivating the voice activation unit when the at least one sound feature indicates a non-target keyword. | 11-13-2014 |
20140337031 | METHOD AND APPARATUS FOR DETECTING A TARGET KEYWORD - A method of detecting a target keyword for activating a function in an electronic device is disclosed. The method includes receiving an input sound starting from one of the plurality of portions of the target keyword. The input sound may be periodically received based on a duty cycle. The method extracts a plurality of sound features from the input sound, and obtains state information on a plurality of states associated with the portions of the target keyword. Based on the extracted sound features and the state information, the input sound may be detected as the target keyword. The plurality of states includes a predetermined number of entry states indicative of a predetermined number of the plurality of portions. | 11-13-2014 |
20150078667 | METHOD AND APPARATUS FOR SELECTIVELY PROVIDING INFORMATION ON OBJECTS IN A CAPTURED IMAGE - A method for providing object information for a scene in a wearable computer is disclosed. In this method, an image of the scene is captured. Further, the method includes determining a current location of the wearable computer and a view direction of an image sensor of the wearable computer and extracting at least one feature from the image indicative of at least one object. Based on the current location, the view direction, and the at least one feature, information on the at least one object is determined Then, the determined information is output. | 03-19-2015 |
20150081296 | METHOD AND APPARATUS FOR ADJUSTING DETECTION THRESHOLD FOR ACTIVATING VOICE ASSISTANT FUNCTION - A method for activating a voice assistant function in a mobile device is disclosed. The method includes receiving an input sound stream by a sound sensor and determining a context of the mobile device. The method may determine the context based on the input sound stream. For determining the context, the method may also obtain data indicative of the context of the mobile device from at least one of an acceleration sensor, a location sensor, an illumination sensor, a proximity sensor, a clock unit, and a calendar unit in the mobile device. In this method, a threshold for activating the voice assistant function is adjusted based on the context. The method detects a target keyword from the input sound stream based on the adjusted threshold. If the target keyword is detected, the method activates the voice assistant function. | 03-19-2015 |
20150082330 | REAL-TIME CHANNEL PROGRAM RECOMMENDATION ON A DISPLAY DEVICE - A method of providing a channel program recommendation in real-time for a display device is disclosed. The method includes receiving a plurality of multimedia signal streams for a plurality of channel programs, and generating in real-time at least one video and audio content tag based on at least one of video and audio contents from the multimedia signal streams. The display device generates the channel program recommendation including at least one of the channel programs based on the at least one video and audio content tag and at least one of a plurality of viewing criteria. A notification of the channel program recommendation is then output. | 03-19-2015 |
