Abstract: A control device for an unmanned aerial vehicle (UAV) and a control method therefor are provided. The control device includes a sensing device, an image receiver, a control transmitter, a display, and a processor. The sensing device is used to sense an action of the user. The image receiver is used to receive an image including at least a part or all of the body in the UAV from a first image capturing device of the UAV. The processor uses the display to continuously present the image. The processor obtains the action by the sensing device, converts the action into the control signal corresponding to the UAV, and transmits the control signal to the UAV through the control transmitter. The UAV is controlled by the control signal transmitted by the control device.

Abstract: A self-adaptive adjustment method for a hearing aid is provided. Audio adjustment parameters including a first audio compression rate, a second audio compression rate and a preset volume compression threshold are previously stored in the hearing aid. The self-adaptive adjustment method includes (S1) receiving and converting an external sound source into an input audio signal, (S2) converting the input audio signal into a first output audio signal at a first audio compression rate, (S3) determining a relative relation between the set output volume level and the default volume level of the hearing aid, calculating a dynamic volume compression threshold, and comparing and determining whether the volume of the input audio signal is greater than the dynamic volume compression threshold, and (S4) converting the input audio signal into a second output audio signal at a second audio compression rate.

Abstract: A hearing assistance system is provided. The hearing assistance system includes a first assisting device and a second assisting device. The first assisting device includes a first sound collection module, a first audio processing unit, a first audio output module and a first communication unit. The second assisting device includes a second sound collection module, audio processing module, a second audio output module, a processor unit and a second communication unit. The processor unit outputs a second control signal according to a first audio signal and a second audio signal by mutual communication between the communication units. The audio processing module outputs a second output audio signal to the second audio output module in accordance with the second control signal, so that the second audio output module outputs the second sound in accordance with the second output audio signal.

Abstract: An activity recognition method includes steps of obtaining a plurality of embedded feature values, converting a data set obtained by at least one sensor into an activity feature value, comparing the activity feature value with the embedded feature values to generate a comparison result, and performing an activity recognition according to the comparison result. Therefore, the present invention achieves the advantages of precisely recognizing activities.

Abstract: A system and a method for evaluating noise cancelling capability are provided, and the system and method are configured to evaluate a noise cancelling capability of an external device. The system includes a mixer, a player, a recorder and a comparator. The mixer receives and mixes a target audio file and a noise audio file and outputs a mix audio file. The player is connected to the mixer for receiving the mix audio file. The player outputs a first audio signal to the external device. The external device cancels the noise of the first audio signal and outputs a second audio signal. The recorder receives the second audio signal and outputs a noise-cancelled audio file. The comparator is connected to the recorder for receiving the noise-cancelled audio file. The comparator compares the noise-cancelled audio file and the target audio file and outputs an evaluation report according to a comparing result.
