Information processing device, system, and information processing method

摘要

An information processing device according to an embodiment of the present invention includes a detection unit, a calculation unit, a determination unit, and an estimation unit. The detection unit detects each three-dimensional position of a plurality of parts of an instruction object for indicating an image output surface. The calculation unit calculates an intersection point of a direction indicated by the instruction object and the image output surface based on each three-dimensional position of the parts of the instruction object. The determination unit determines whether the intersection point is within a predetermined range on the image output surface. The estimation unit estimates a position indicated by the instruction object on the image output surface based on the determination made by the determination unit.

1. An information processing device comprising:
circuitry configured to
detect three-dimensional positions of a plurality of parts of an instruction object of a user for indicating a position on an image output surface to which an image is output,calculate an intersection point of a direction indicated by the instruction object and the image output surface based on the detected three-dimensional positions of the parts of the instruction object,determine whether or not the intersection point is within a predetermined range on the image output surface, the predetermined range corresponding to a region of the image output surface reachable by the instruction object of the user,when it is determined that the intersection point is within the predetermined range,
select a position of the detected three-dimensional positions of the parts of the instruction object, the selected position being closest to the image output surface among the detected three-dimensional positions,determine whether the selected position is within a predetermined distance from the image output surface, andwhen it is determined that the selected position is within the predetermined distance from the image output surface, estimate, as the position indicated by the instruction object, coordinates of a position on the image output surface having a shortest distance between the image output surface and the selected position, andwhen it is determined that the intersection point is outside the predetermined range, estimate the intersection point as the position indicated by the instruction object.
