Abstract
An absolute coordinate pointing device defines an (x,y) plane drawing region wherein user manipulation of a control element controls (x,y) location of first light source optical energy detectable by a first light sensor array that outputs (x,y) Cartesian coordinate data representing control element (x,y) movement. A pantograph coupled between the control element and first light source optical energy provides scaling. Pointing device (x,y) data output can control cursor position on a companion device display screen. Control element location on the drawing region is commensurate with cursor location on the display screen. Optionally an additional pantograph member can pivot in the z-direction with z-displacement of the control element. Z-axis location of optical energy from a second light source moves with z-movement of this pivoting member. A second light sensor array senses this optical energy and outputs z-axis Cartesian coordinate data representing control element z-displacement.
