Abstract: Provided is an information processing device including: a projection unit configured to project an image on a projection surface; an acquisition unit configured to acquire depth information on a projection surface containing a pointing object; a fingertip area extraction unit configured to extract a tip area of the pointing object from the depth information; a fingertip position determination unit configured to determine a tip position of the pointing object in a height direction from the projection surface based on a histogram generated from a group of pieces of depth information on the tip area; an operation detector configured to detect an operation by the pointing object based on the tip position; and a projection controller configured to cause the projection unit to project an image generated in accordance with the detected operation.

Abstract: An information processing apparatus includes an obtainment unit configured to obtain information indicating a proximity state of an object and a predetermined operation surface, a setting unit configured to set a condition regarding the proximity state for determining whether the object is released from the operation surface based on a moving speed of the object in a period during which the object is regarded as touching the operation surface for input by the information obtained by the obtainment unit, and a determination unit configured to determine that the object is released from the operation surface in response to that the information obtained by the obtainment unit satisfies the condition set by the setting unit.

Abstract: A video data display apparatus for reproducing and displaying video data calculates an operation speed based on an input user operation, determines a reproduction speed according to the calculated operation speed, and reproduces video data at the determined reproduction speed. Here, the video data display apparatus acquires section information indicating a section selected from the video data, and, in a case where the calculated operation speed exceeds a prescribed operation speed, determines the reproduction speed for performing reproduction, such that a reproduction speed of video data belonging to the selected section indicated by the section information is slower than a reproduction speed of video data not belonging to the selected section.

Abstract: An information processing method enlarges or reduces and displays an area of a part of image data, displayed on a display unit, in response to a user's operation and determines, based on objects included in the enlarged or reduced and displayed area and on objects included in a plurality of image data pieces, a display order of the plurality of image data pieces.
