A method of playing advertisements according to exemplary embodiments includes collecting data of at least two viewers near a display, extracting relationship information of the at least two viewers based on the data, determining advertisements to play on the display according to the relationship information, and playing the determined advertisements on the display.
Opening claim text (preview).
What is claimed is: 1. A method of playing advertisements on a display device including a camera and a depth sensor, the method comprising: generating a first detection box corresponding to a first viewer and a second detection box corresponding to a second viewer, based on image data obtained via the camera; collecting data of the first viewer and the second viewer based on the image data obtained via the camera; determining a first distance between the first viewer and the display device via the depth sensor; determining a second distance between the second viewer and the display device via the depth sensor; determining a third distance between the first viewer and the second viewer based on a difference between the first distance and the second distance; determining a fourth distance between the first viewer and the second viewer based on the first detection box and the second detection box; determining relationship information of the first viewer and the second viewer based on the data, the third distance and the fourth distance; and displaying advertisements determined according to the relationship information on the display device. 2. The method of claim 1 , wherein the camera comprises at least one selected from a visible light camera, and an infrared camera. 3. The method of claim 1 , wherein the determining of the relationship information comprises extracting body features of the first viewer and the second viewer from the data, and wherein the body features of the first viewer and the second viewer comprise at least one selected from face features of the first viewer and the second viewer, and body related information of the first viewer and the second viewer. 4. The method of claim 3 , wherein the face features of the first viewer and the second viewer comprise at least one selected from the number of faces, features of the facial organs, face skin color, age, gender, viewpoints, and facial accessories. 5. The method of claim 3 , wherein the body related information of the first viewer and the second viewer comprises at least one selected from the number of bodies, features of body parts, movements of the bodies, hairstyle, clothing, body shapes, and carried items. 6. The method of claim 1 , further comprising storing personal information of the first viewer and the second viewer in advance, and wherein the determining of the relationship information comprises: searching for personal information that matches with the data from among the personal information; and extracting, based on the personal information that matches with the data, the relationship information between the first viewer and the second viewer. 7. The method of claim 1 , wherein the determining of the relationship information comprises determining whether a relationship between the first viewer and the second viewer is family, friends, or colleagues. 8. The method of claim 1 , wherein the determining of the relationship information comprises extracting at least one piece of information from gender, age, skin color, hairstyle, clothing, body shapes, facial accessories, and carried items of the first viewer and the second viewer. 9. A device for playing advertisements, the device comprising: a display device; an input interface comprising a camera and a depth sensor; and at least one processor configured to: generate a first detection box corresponding to a first viewer and a second detection box corresponding to a second viewer based on image data obtained via the camera, collect data of the first viewer and the second viewer based on the image data obtained via the camera, determine a first distance between the first viewer and the display device via the depth sensor, determine a second distance between the second viewer and the display device via the depth sensor, determine a third distance between the first viewer and the second viewer based on a difference between the first distance and the second distance, determine a fourth distance between the first viewer and the second viewer based on the first detection box and the second detection box, determining relationship information of the first viewer and the second viewer based on the data of the first viewer and the second viewer, the third distance and the fourth distance, and control the display device to display advertisements determined according to the relationship information. 10. The device of claim 9 , wherein the camera comprises at least one selected from a visible light camera, and an infrared camera. 11. The device of claim 9 , wherein the at least one processor is further configured to extract body features of the first viewer and the second viewer from the data, and determine advertisements to play based on the body features, and wherein the body features of the first viewer and the second viewer comprise at least one selected from a distance between the first viewer and the second viewer, face features of the first viewer and the second viewer, and body related information of the first viewer and the second viewer. 12. The device of claim 9 , further comprising a memory configured to store personal information of the first viewer and the second viewer in advance, and wherein the at least one processor is further configured to search for personal information that matches with the data from among the personal information, and extract the relationship information between the first viewer and the second viewer based on the personal information that matches the data. 13. The device of claim 9 , wherein the input interface further comprises a microphone, and wherein the at least one processor is further configured to: collect sound information via the microphone, and determine the relationship information of the first viewer and the second viewer based on the data of the first viewer and the second viewer, the third distance, the fourth distance and the sound information. 14. The device of claim 13 , wherein the at least one processor is further configured to: identify a threshold value, identify the sound information as voice information based on a power level a converted power spectrum signal of the sound information exceeding the threshold value, identify the sound information as noise information based on the power level the converted power spectrum signal of the sound information being less than the threshold value, and filter the noise information from the sound information used to determine the relationship information of the first viewer and the second viewer. 15. The device of claim 14 , wherein the at least one processor is further configured to identify the power level of the converted power spectrum signal of the sound information using a fast Fourier Transform. 16. The device of claim 9 , wherein the at least one processor is further configured to: extract body features of the first viewer and the second viewer from the image data, and determine the relationship information of the first viewer and the second viewer based on the data of the first viewer and the second viewer, the third distance, the fourth distance and the body features. 17. The device of claim 16 , wherein the at least one processor is further configured to: identify a first direction corresponding to a first viewpoint of the first viewer, identify a second direction corresponding to a second viewpoint of the second viewer, and identify the body features of the first viewer and the second viewer based on the first direction and the second direction. 18. The device of claim 17 , wherei
