A method of and system for providing user input to a computer, or the like, having a display by detecting a change in fingerprint pattern of a user. The system controls the position of a pointer on a display by detecting motion of ridges and pores of a fingerprint of a user and moving the pointer on the display according to detected motion of the ridges and pores of the fingerprint. The system captures successive images of the fingerprint ridges and pores and detects motion of the ridges and pores based upon the captured successive images.
