Abstract:
1. A method for selecting an external processor as a user interface to a machine comprising: accessing control grid position information for the machine, wherein the control grid position information provides a control grid of the machine comprising a subset of an effective positioning space covered by a positioning system; obtaining position information for the external processor using the positioning system; and using the control grid position information and the external processor position information to determine if the external processor is in the control grid of the machine, and only if the external processor is located in the control grid of the machine, transferring user interface control of the machine to the external processor, wherein, the machine is located in a space that includes a floor, the space having an additional machine and wherein the control grid corresponds to a defined portion of the floor space in proximity to the machine that does not overlap with space occupied by the additional machine.
