Abstract
When a plurality of operators perform pointing operations, a pointing control device selects a pointer for determining a position to be pointed from among the operators by using the distance between a face and a fingertip or a substitute for a fingertip of each operator. The pointing device calculates the distance between the face and the fingertip or the substitute for each operator by using a position of the face and a position of the fingertip or the substitute, selects a pointer from the operators by using the calculated distance, and calculates a position of a cursor for a pointing operation based on the position of the fingertip or the substitute calculated for the selected pointer. A pointer can be selected regardless of the number of operators, and a pointer can easily change to another operator.
