Abstract

A method of ordering and an order entry system which includes a display showing, pictorially, the elements or items to be selected from a menu. An aiming selector is used to make the selections desired. Each item on the menu contains a light-responsive detector which is selected by aiming the aiming selector at the desired item. A first light signal from the selector falling on the detector of the desired item causes the item about to be selected to 'flash' on the display, and a switch on the selector, when actuated, causes a second light signal to fall on the associated detector for the item to make the selection. A control element having a similar detector is similarly used to enter a command like 'Total Up Order' which is used by the system to calculate the monetary value of the order.
