Abstract: The present specification provides a method and an apparatus for face tracking robust to face rotation. The face tracking method of the present specification comprises the steps of: receiving an image including a user′s face; predicting an area having the high possibility for the face and the degree of rotation of the face within the image; detecting a facial area where the face exists from the image based on the predicted value; calculating the similarity of the facial area in a horizontal direction to obtain the degree of rotation of the face; and compensating the predicted value, based on the position of the face and the degree of rotation thereof, to extract the compensated facial area.

Abstract: The present invention relates to a method and an apparatus for transmitting and receiving a multi-stream in an interactive service, and provides a method for transmitting a second stream in synchronization with a first stream being transmitted by a server, and the method comprises steps of receiving, from a client, a second stream synchronization reproduction request message indicating a request for transmission of the second stream such that the second stream should be synchronized with the first stream and including an identifier of the first stream, checking the first stream corresponding to the second stream based on the identifier, and synchronizing the second stream with the first stream based on a reproduction point of the first stream; and transmitting the second stream to the client, starting from the reproduction point synchronized with the first stream. When multiple streams need to be reproduced in synchronization, the server matches a reproduction point of another stream with reference to any one stream and transmits the other stream to the client, thus, minimizing receiving of unnecessary stream data, a waste of a buffer, and the time for the client to wait for reproducing a stream.

Abstract: Disclosed in the present invention is a dynamic key button display method capable of shortening key input time by dynamically arranging keys according to how often each Korean alphabet is used and being differentiated for each user. According to the present invention, the dynamic key button display method includes: a step of extracting an initial consonant group from a first database and displaying the extracted initial consonant group; a step of selecting an initial consonant from the initial consonant group and displaying the selected initial consonant; a step of extracting a vowel candidate group applicable to the selected initial consonant from a second database and displaying vowels in the vowel candidate group in the descending order of use frequency how often each vowel is used together with the selected initial consonant in a way that the most frequently used vowel is placed the closest to the selected initial consonant; a step of selecting a vowel from the vowel group, displaying a letter which is the combination of the selected initial consonant and the selected vowel, and updating the use frequency of the selected vowel into the second database; a step of extracting an available final consonant group for the letter from a third database and displaying consonants in the final consonant group in the descending order of use frequency how often each consonant is used together with the letter in a way that the most frequently used consonant is placed the closest to the letter; and a step of selecting a final consonant from the final consonant group and updating the use frequency of the selected final consonant into the third database.
