Wearable apparatus and unmanned aerial vehicle system

Abstract

A shading member includes a main body and a supporting component coupled to the main body. The supporting component is configured to change a light transmittance of the shading member under a voltage applied by an adjusting device for switching the shading member in two states. The two states include a transparent state and a shading state. The light transmittance of the shading member corresponds to an amount of external light that enters a wearable apparatus. The wearable apparatus operates in a virtual reality mode when the shading member operates in the shading state, and the wearable apparatus operates in an augmented reality mode when the shading member operates in the transparent mode.
