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. The disclosure allows a user to control an information apparatus in a field of view anytime and anywhere, and interact with the device as What You See Is What You Get (WYSIWYG).

Optical tag based information apparatus interaction method and system

A method for guiding an autonomously movable machine by means of an optical communication device having associated identification, location and orientation information. The method includes: receiving location information of a destination to which the autonomously movable machine travels, where the location information of the destination is determined by scanning and identifying, at the destination, at least one optical communication device around the destination; scanning and identifying the at least one optical communication device around the autonomously movable machine by means of the camera mounted on the autonomously movable machine, so as to determine location information of the autonomously movable machine; and on the basis of the location information of the destination and the location information of the autonomously movable machine, determining the relative location relationship between the autonomously movable machine and the destination, and controlling the autonomously movable machine or a part thereof to travel to the destination.

Method for guiding autonomously movable machine by means of optical communication device

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.

Optical communication device and method for transmitting and receiving information

An optical communication device is provided. The optical communication device includes at least one light source and a controller configured to continuously control, by a light source control signal, each of the at least one light source to operate in at least two modes. The at least two modes include a first mode and a second mode. The first mode is used to transfer a first information, and the second mode is used to transfer a second information different from the first information. For any one of the at least one light source, in the first mode, the light source control signal has a first frequency so that a stripe presents in a first image of the light source obtained when the light source is photographed by a CMOS image sensor, and in the second mode, a second image of the light source obtained when the light source is photographed by the CMOS image sensor is substantially free from any stripe.

Optical communication device and system, and corresponding information transmitting and receiving methods

A display device and its display method are provided. The display method includes: first, inputting image message, then generating laser beams for forming an image according to the input image message to display an image. The image message includes angular message of each image pixels.
