Abstract: The present disclosure provides an optical tag-based information apparatus interaction method and system. The method includes: using a terminal device to perform image acquisition on an optical tag at a relative fixed position to an information apparatus so as to determine a position and an attitude of the terminal device relative to the optical tag; determining, in conjunction with a predetermined position of each information apparatus relative to the optical tag, the position of the terminal device relative to each information apparatus; acquiring an imaging position of each information apparatus on a display screen of the terminal device, and displaying an interactive interface of each information apparatus at the imaging position thereof on the display screen, such that an interactive operation can be performed on each information apparatus.

BEIJING WHYHOW INFORMATION TECHNOLOGY CO., LTD.
Abstract: Disclosed are an optical communication device and a method for transmitting and receiving information. The optical communication device includes at least two light sources including a first light source and a second light source, and a controller configured to drive the first light source and the second light source in one or more driving modes. The first light source and the second light source are driven in a same driving mode for transmitting first information, and the first light source and the second light source are driven in different driving modes including a first driving mode and a second driving mode which have the same or different frequencies for transmitting other information different from the first information.

Abstract: Disclosed are an apparatus for implementing relative positioning and a corresponding relative positioning method. A positioning apparatus includes one or more first positioning markers and one or more second positioning markers. The first positioning markers define a plane. At least a subset of the second positioning markers is located outside the plane defined by the first positioning markers.
