Methods and apparatuses pertaining to enhanced audio effect realization for virtual reality may involve receiving data in a virtual reality setting. The data may be related to audio samples from one or more sound sources, motions of the one or more sound sources, and motions of a user. Physics simulation may be performed for realization of one or more audio effects based on the received data. Signal processing may be performed using a result of the physics simulation. Audio outputs may be provided using a result of the signal processing.

A voice control device has a speech command recognizer, a sensor data processor and a decision making circuit. The speech command recognizer is arranged for performing speech command recognition to output a recognized speech command. The sensor data processor is arranged for processing sensor data generated from at least one auxiliary sensor to generate a detection output. The decision making circuit is arranged for deciding a response of the voice control device according to the recognized speech command and the detection output. The same speech command is able to trigger difference responses according to the detection output (e.g., detected motion). Besides, an adaptive training process may be employed to improve the accuracy of the sensor data processor. Hence, the voice control device may have improved performance of the voice control feature due to a reduce occurrence probability of miss errors and false alarm errors.

A portable electronic device including an ultrasound transmitter, an ultrasound receiver, and a processing unit is provided. The ultrasound transmitter sends ultrasonic signals, while the ultrasound receiver receives reflected ultrasonic signals from an object. The ultrasound transmitter and the ultrasound receiver are disposed to form a reference axis. The processing unit processes the reflected ultrasonic signals to obtain a time-frequency distribution thereof, and determines a 1D gesture corresponding to projection loci of movements of the object on the reference axis according to the time-frequency distribution.
