Abstract: A method and an apparatus for producing situational acousto-optic effect are provided. In the method, a sound signal is detected and a fast Fourier transform (FFT) and a normalization calculation are performed on the sound signal to produce a frequency domain signal. Then, a plurality of frequencies having variations between the frequency domain signals produced before and after a time point are determined whether to fit in with a frequency spectrum of a specific tone. Once the frequencies fit in with the frequency spectrum, a light source is controlled to produce light with a color corresponding to the specific tone.

Abstract: A wearable apparatus includes a user interface, a motion sensor, a microprocessor and a central processing unit (CPU). In an operation mode, the motion sensor senses a current hand movement trajectory (HMT). The microprocessor generates a velocity curve along a coordinate axis according to the current HMT, and samples the velocity curve according to a first predetermined velocity and a second predetermined velocity to output velocity sampling points. The microprocessor further determines whether a matching number between the velocity sampling points and velocity feature points is greater than a threshold. The current HMT matches a predetermined HMT when the matching number is greater than the threshold. The CPU performs a system operation corresponding to the default HMT when the current HMT matches the predetermined HMT.
