Claim 11:
12. The apparatus according to claim 11, wherein the second group of hand bone points comprises a thumb fingertip bone point and an index fingertip bone point, and the processor is further configured to:
obtain, according to two-dimensional coordinates of the thumb fingertip bone point and the index fingertip bone point, three-dimensional coordinates of the thumb fingertip bone point and the index fingertip bone point;
obtain, according to the three-dimensional coordinates, a three-dimensional Euclidean distance between the thumb fingertip bone point and the index fingertip bone point, and determining, according to the three-dimensional Euclidean distance, a three-dimensional positional relation between the thumb fingertip bone point and the index fingertip bone point; and
obtain, according to a contour between the thumb fingertip bone point and the index fingertip bone point and the two-dimensional coordinates, a two-dimensional Euclidean distance between the thumb fingertip bone point and the index fingertip bone point and a distance of the contour, and determining, according to the two-dimensional Euclidean distance and the distance of the contour, a two-dimensional positional relation between the thumb fingertip bone point and the index fingertip bone point.
