Abstract:
A device includes a memory and a processor. The memory is configured to store a threshold. The processor is configured to authenticate a user based on authentication data. The processor is also configured to, in response to determining that the user is authenticated, generate a correlation score indicating a correlation between a first signal received from a first sensor and a second signal received from a second sensor. The processor is also configured to determine liveness of the user based on a comparison of the correlation score and the threshold.
Abstract:
A method, performed in a control device, for adjusting a display device in communication with the control device is disclosed. The method may include receiving an image of a scene including the display device from an image sensor configured with a field of view overlapping at least a portion of view of a user. A display condition of the display device may be detected from the image. The control device may determine context information associated with the user from the image. Based on the display condition and the context information associated with the user, an output display condition of the display device may be determined. A control signal for adjusting the display device may then be generated based on the output display condition.
Abstract:
A method for verifying at least one sound sample to be used in generating a sound detection model in an electronic device includes receiving a first sound sample; extracting a first acoustic feature from the first sound sample; receiving a second sound sample; extracting a second acoustic feature from the second sound sample; and determining whether the second acoustic feature is similar to the first acoustic feature.
Abstract:
A method, which is performed in a first electronic device, for authorizing access to a second electronic device is disclosed. The method may include establishing communication between the first electronic device and the second electronic device. The method may also obtain data indicative of a motion of at least one of the first and second electronic devices in response to a movement of the at least one of the first and second electronic devices. Based on the data, a control signal authorizing access to the second electronic device is generated, and transmitted to the second electronic device.

Abstract:
A method for performing a function in an electronic device is disclosed. The method may include receiving an input sound stream including a speech command indicative of the function and identifying the function from the speech command in the input sound stream. Further, the method may determine a security level associated with the speech command. It may be verified whether the input sound stream is indicative of a user authorized to perform the function based on the security level. In response to verifying that the input sound stream is indicative of the user, the function may be performed.
Abstract:
A method, performed by a connection manager, for connecting an input device and one of a plurality of electronic devices as a target device is disclosed. The method includes detecting a face of a user in a captured image, and determining a first gaze direction of the user from the face of the user in the captured image. Based on the first gaze direction, the method determines the target device in the plurality of electronic devices and connects the input device and the target device.
Abstract:
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.
Abstract:
Various arrangements for detecting a type of sound, such as speech, are presented. A plurality of audio snippets may be sampled. A period of time may elapse between consecutive audio snippets. A hypothetical test may be performed using the sampled plurality of audio snippets. Such a hypothetical test may include weighting one or more hypothetical values greater than one or more other hypothetical values. Each hypothetical value may correspond to an audio snippet of the plurality of audio snippets. The hypothetical test may further include using at least the greater weighted one or more hypothetical values to determine whether at least one audio snippet of the plurality of audio snippets comprises the type of sound.
Abstract:
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.
