Pointing control device, integrated circuit thereof and pointing control method

摘要

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.

主权项

1. A pointing control device for selecting, from operators who perform a pointing operation of pointing at a position on a screen, a pointer who is allowed to determine a position of a cursor displayed on the screen, the pointing control device comprising:
a position acquiring unit configured to, for each operator, acquire a position of a face and acquire a position of a fingertip or a substitute for a fingertip; a distance calculating unit configured to associate, for each operator, the position of the face with the position of the fingertip or the substitute, and to calculate, for each operator, a distance between the position of the face and the associated position of the fingertip or the substitute; a pointer selecting unit configured to select the pointer by using the distance; and a cursor position calculating unit configured to calculate the position of the cursor by using the position of the fingertip or the substitute acquired for the pointer, and to output the position of the cursor.
