    摘要： An environmental-light filter removably coupled to an optical see-through head-mounted display (HMD) device is disclosed. The environmental-light filter couples to the HMD device between a display component and a real-world scene. Coupling features are provided to allow the filter to be easily and removably attached to the HMD device when desired by a user. The filter increases the primacy of a provided augmented-reality image with respect to a real-world scene and reduces brightness and power consumption requirements for presenting the augmented-reality image. A plurality of filters of varied light transmissivity may be provided from which to select a desired filter based on environmental lighting conditions and user preference. The light transmissivity of the filter may be about 70% light transmissive to substantially or completely opaque.
