    Abstract: A multidirectional optical positioning method and a device thereof, and more particularly a signal transmission and positioning method applied to visible light communication and a device thereof. The device includes a transparent board having multiple different light conversion layers on the surface. The light conversion layers are arranged in one single axial direction. A light emitting unit is used to project an incident light onto an incident side of the transparent board. After the incident light passes through the light conversion layers, the incident light is converted into multiple radiating lights with different physical effects, which are emitted from an emission side of the transparent board. A sensor is disposed on the emission side of the transparent board to receive the radiating lights, whereby the position of the sensor can be found according to different extents of the physical effects of the different radiating lights.
