Abstract
Embodiments of the present invention provide a pointing interaction method, apparatus, and system. The method includes: obtaining a hand image and an arm image; determining spatial coordinates of a fingertip according to the hand image, and determining spatial coordinates of an arm key portion according to the arm image; and performing converged calculation on the spatial coordinates of the fingertip and the spatial coordinates of the arm key portion, to determine two-dimensional coordinates, on a display screen, of an intersection point between fingertip pointing and the display screen. Therefore, the pointing interaction apparatus can implement high-precision pointing only by using the spatial coordinates of the fingertip and the spatial coordinates of the arm key portion, and the pointing has good realtimeness.
