Abstract: An information processing apparatus according to an embodiment of the present technology includes a line-of-sight estimator, a correction amount calculator, and a registration determination section. The line-of-sight estimator calculates an estimation vector obtained by estimating a direction of a line of sight of a user. The correction amount calculator calculates a correction amount related to the estimation vector on the basis of at least one object that is within a specified angular range that is set using the estimation vector as a reference. The registration determination section determines whether to register, in a data store, calibration data in which the estimation vector and the correction amount are associated with each other, on the basis of a parameter related to the at least one object within the specified angular range.

Abstract: The present technology relates to an information processing device, a method, and a program capable of reducing the visual load of a video.
An information processing device includes an input acquisition unit that acquires user input that designates a display range of a free-viewpoint video, and a control unit that controls a virtual camera that determines the display range of the free-viewpoint video on the basis of the user input. When the control unit changes an angle of view of the virtual camera from a first angle of view including a first target to a second angle of view including a second target, if at least one of pan rotation or tilt rotation of the virtual camera has a predetermined angular velocity, the control unit performs at least one of the pan rotation or the tilt rotation while moving the virtual camera away from the first target, and if the angular velocity of the pan rotation and the tilt rotation of the virtual camera is smaller than the predetermined angular velocity, the control unit performs at least one of the pan rotation or the tilt rotation while maintaining the distance between the virtual camera and the first target. The present technology can be applied to an information processing device.
