PROBLEM TO BE SOLVED: To more accurately estimate the viewing situation of a user even if image information of a camera cannot be used.SOLUTION: A viewing situation determination device 3 comprises: face recognition means 31 for recognizing user's face using image information photographed by a camera 1; moving body detection means 33 for detecting the moving body of the user using the image information; sound detection means 31 for detecting the sound of the user using sound information obtained by a microphone 2; frequency feature amount calculation means 37 which calculates the frequency feature amount of the face recognition, that of the detection of the moving body, and that of the sound detection, using data on the result of the face recognition obtained by the face recognition means 31, the result of the detection of the moving body obtained by the moving body detection means 33, and the result of the sound detection obtained by the sound detection means 35, the respective results having been accumulated for a predetermined period; and determination means 38 which inputs to a previously constructed identifier 39 the result of the face recognition, the result of the detection of the moving body, and the result of the sound detection and determines whether the viewing situation of the user is a concentrating state or a non-concentrating state. |
