Abstract: According to one embodiment, an information processing apparatus is provided with a display section, and can be instructed to be operated by a pointer displayed on the display section, and includes a detection section for detecting, from an input image of a hand, a position of the hand in the image, an operation section for obtaining a probability that the hand exists in the image by using the latest detection result detected by the detection section, and a value of a probability distribution function having a peak at a position which has been evaluated last time as a position at which a probability that the hand exists is high, and a pointer display section for moving the pointer, on the basis of an evaluation value obtained from the probability, to a position at which the probability that the hand exists is the highest and displaying the pointer at the position.

Abstract: According to one embodiment, an information processing device includes a position detecting section configured to detect a position of a hand from an input image of the hand, a memory section configured to store data of the position of the hand detected by the position detecting section, a rotation judging section configured to judge, assuming that records of the data of the position of the hand stored in the memory section show a rotary movement, that a latest position of the hand falls in an angle range predicted for the rotary movement, and an executing section configured to, when the rotation judging section judges that the latest position of the hand falls in the angle range, obtain a rotational angle at the latest position of the hand and also execute a process that corresponds to a predetermined rotary movement of the hand.
