Abstract:
A method includes receiving a first output from a first sensor of an electronic device and receiving a second output from a second sensor of the electronic device. The first sensor has a first sensor type and the second sensor has a second sensor type that is different from the first sensor type. The method also includes detecting a gesture based on the first output and the second output according to a complementary voting scheme that is at least partially based on gesture complexity.
Abstract:
The disclosure is directed to storing trace information. An aspect includes determining whether or not a pen is within a threshold distance of the touchscreen storing trace information generated by a user s touch in a touch buffer if the pen is not within the threshold distance of the touchscreen and clearing the touch buffer and storing trace information generated by the pen in the touch buffer if the pen is within the threshold distance of the touchscreen.
Abstract:
Un método (M100) para procesar una señal multicanal que incluye un primer canal de entrada de audio y un segundo canal de entrada de audio, comprendiendo dicho método: realizar (T100) una operación de cancelación activa de ruido en el primer canal de entrada de audio para producir una señal antirruido; procesar (T200) la señal multicanal para obtener un componente fuente, incluyendo dicho procesamiento realizar una operación de procesamiento espacialmente selectiva en la señal multicanal para separar el componente fuente de un componente de fondo; procesar (T300) el componente fuente separado obtenido para producir un componente objetivo: producir una señal aumentada del componente objetivo, en donde la señal aumentada es una señal estéreo que proporciona una dirección de llegada percibida correspondiente a una dirección de llegada asociada con el componente fuente separado obtenido, en donde la dirección de llegada asociada con el componente fuente separado obtenido se determina a partir del primer canal de entrada de audio y el segundo canal de entrada de audio; y combinar (T400) la señal antirruido y la señal aumentada para producir una señal de salida de audio.
Abstract:
The embodiments provide systems and methods for touchless sensing and gesture recognition using continuous wave sound signals. Continuous wave sound, such as ultrasound, emitted by a transmitter may reflect from an object, and be received by one or more sound receivers. Sound signals may be temporally encoded. Received sound signals may be processed to determine a channel impulse response or calculate time of flight. Determined channel impulse responses may be processed to extract recognizable features or angles. Extracted features may be compared to a database of features to identify a user input gesture associated with the matched feature. Angles of channel impulse response curves may be associated with an input gesture. Time of flight values from each receiver may be used to determine coordinates of the reflecting object. Embodiments may be implemented as part of a graphical user interface. Embodiments may be used to determine a location of an emitter.
