We describe an unbeatable rock-scissors-paper (janken) game system which defeats the opponent without fail and never has any delay in the presentation of the hand. This system recognizes the shape of the opponent's hand with pictures taken by a 60-fps camera and displays the hand form that can win a game on the screen before the opponent completes their hand form. When a 60-fps camera used, the whole process, which includes image acquisition, preprocessing the image, recognition of the hand shape and a display of the winning hand form, is done within about 16 msec. The optimal display time is decided on the basis of experience, recognition of the hand form and the time needed to present one of the three symbols without giving the opponent, who has average reactions a feeling of delay.

KARAOKE is a popular amusement for old and young. Many KARAOKE machines have singing evaluation function. However, it is often said that the scores given by KARAOKE machines do not match human evaluation. In this paper a KARAOKE scoring method strongly correlated with human evaluation is proposed. This paper proposes a way to evaluate songs based on the distance between singing pitch and musical scale, employing a vibrato extraction method based on template matching of spectrum. The results show that correlation coefficients between scores given by the proposed system and human evaluation are -0.76∼-0.89.
