Apparatus for visible light communication providing intuitive information and method using the same
There is disclosed a visible light communication technology capable of intuitively recognizing a transmission speed, an alignment status, a communication status, or a transmission rate. A visible light communication apparatus according to an embodiment of the present invention includes: a light source selecting unit selecting at least one light source of a plurality of light sources generating lights having different wavelengths by considering intuitive information distinguished depending on a wavelength in a visible light band; and a visible light communication unit performing visible light communication by at least one selected light source to allow the intuitive information to be recognized by a color corresponding to at least one selected light source. Accordingly, a user using the visible light communication can intuitively know an optimal communication status or transmission speed.
1. An apparatus for a visible light communication, comprising:
a light source selecting unit selecting a light source for representing a color corresponding to a status of the apparatus for the visible light communication; and
a visible light communication unit providing light corresponding to the color for a user to recognize the status visually,
wherein the status includes at least one of a communication status, channel status and file transfer status of the visible light communication,
wherein the visible light communication unit transmits a color packet corresponding to the color for the user to recognize the color,
wherein the color packet includes a color packet pattern, wherein the color packet is used between changes of the communication status.
2. The apparatus of claim 1 , wherein the visible light communication unit transfers the color packet for providing information on the communication status between a connection request packet and a connection response packet.
3. A method of a visible light communication, comprising:
selecting a light source for representing a color corresponding to a status of an apparatus performing the visible light communication; and
providing light corresponding to the color for a user to recognize the status visually,
wherein the status includes at least one of a communication status, channel status and file transfer status of the visible light communication,
wherein the providing light corresponding to the color, transmits a color packet corresponding to the color for the user to recognize the color,
wherein the color packet includes a color packet pattern, wherein the color packet is used between changes of the communication status.
4. The method of claim 3 , wherein the providing light corresponding to the color, transfers the color packet for providing information on the communication status between a connection request packet and a connection response packet.
