Abstract: A controller for controlling a computer display cursor includes an arena having a predefined optical grid. A puck handle is configured to move a puck on the optical grid and to reflect optical signals to the grid regarding the position of the puck on optical grid. The optical grid defines the resolution of the puck movements and positions that can be ascertained. Gratings formed by undulations in transparent walls provide an optical puck position signal in response to the puck position. A processor is coupled to the optical grid and is configured to receive the puck position signal and to generate a cursor position signal. To generate the cursor position signal, the processor may perform a conversion function based on predetermined criteria. The processor transmits the cursor position signal to a computer having a predefined display size, which displays the cursor at a respective position.

Abstract: A computer pointing system employs two modes of moving a marker on a computer display in correspondence with movement of a finger-grippable element within a pointer area of movement wherein one of the modes of movement produces a movement of the marker proportional to movement of the finger-grippable element and the second mode produces movement of the marker which is equal to the product of a distance of the marker from an edge of a display area of movement times the quotient of the distance of movement of the finger-grippable element divided by the distance of the finger-grippable element to an edge of the pointer area of movement. The second mode can be called by movement of the finger-grippable element at a rate greater than a predetermined rate or at a position within an outer ring area of the pointer area of movement. Edge regions of the pointer area of movement define macro instruction regions which, when called by an operation of a switch, pass macro instructions to a user program.
