Abstract: The disclosure relates to an optical system for an augmented reality apparatus, comprising: an image projection source; and a polarizing beam splitter. The polarizing beam splitter has a beam splitting side adjacent to the image projection source and a transmission side facing away from the image projection source. The polarizing beam splitter is arranged such that light emitted from the image projection source is able to be non-perpendicularly incident on the beam splitting side and be at least partially reflected. The polarizing beam splitter is configured such that when light is incident on the beam splitting side, a polarized light component passes through the polarizing beam splitter and is transmitted through the transmission side thereof, and a polarized light component is reflected from the beam splitting side. The optical system also comprises a polarizer disposed between the image projection source and the beam splitting side of the polarizing beam splitter.

Abstract: The present application discloses an augmented reality apparatus and an optical system thereof. The optical system includes an image source; a bandpass polarizing beam splitter, relative to the image source, defining a beam splitting side adjacent to the image source and a transmission side facing away from the image source, the bandpass polarizing beam splitter being configured to allow polarization splitting of light incident thereon in a given wavelength range and allow transmission of light out of the given wavelength range; a wave plate adjacent to the beam splitting side; and a curved bandpass semi-reflector located downstream of the wave plate in a path of the reflected light and configured to allow reflection of light incident on the curved bandpass semi-reflector in the given wavelength range and allow transmission of light out of the given wavelength range.

Abstract: The present disclosure provides method and apparatus for generating a response in a human-machine conversation. A first sound input may be received in the conversation. A first audio attribute may be extracted from the first sound input, wherein the first audio attribute indicates a first condition of a user. A second sound input may be received in the conversation. A second audio attribute may be extracted from the second sound input, wherein the second audio attribute indicates a second condition of a user. A difference between the second audio attribute and the first audio attribute is determined, wherein the difference indicates a condition change of the user from the first condition to the second condition. A response to the second sound input is generated based at least on the condition change.
