Abstract
A three degree-of-freedom locator device for the control of graphical objects on a computer display mimics natural two-dimensional movement of the user's hand by providing for simultaneous translation and rotation of the graphical object. In one embodiment, a computer mouse-type locator with two trackball and position-encoder sensor systems detects movement of the locator over a stationary pad or like device. The graphical object is selected by a mouse button click. Subsequent two-dimensional translation and rotation of the locator are detected by the dual trackball system and used to control the position and orientation of the graphical object. The result is intuitive control of the placement of the selected object on the computer screen. The natural movement of the mouse in the user's hand is transformed into simultaneously translation and rotation of the object.
