Abstract
The present invention pertains to a computer pointing device having an annular rotating ring that is rotatable by a user to control the movement of a cursor on a computer screen. The annular rotating ring is preferably implemented around a trackball to facilitate the ease of use by the user. The annular rotating ring is made up of three constituent rings, namely, a finger ring, a bearing ring, and a shutter ring. The three constituent rings are constructed in such a way that they are interlocked to eliminate any unnecessary movement or slop during use.
