First Claim
1. A data entry system comprising:
- a display having data entry elements and control elements positioned on said display and lighting means to light up said data entry and control elements when selected;
each said data entry element and control element having a detector associated therewith;
said display also having a first display area for indicating parameters such as the number of units of said data entry elements selected;
an aiming selector having means for emitting first and second light signals directed at said data entry and control elements which are to be selected;
control means for controlling the operation of said data entry system;
said control means including means coupled to said detectors for producing first and second outputs in response to said first light signals and said second light signals, respectively, falling on said detectors;
said first output being used by said control means and said lighting means to give a first indication that said aiming selector is directed to a particular one of said data entry or control elements, and said second output being used by said control means and said lighting means to give a second indication that said particular one of said data entry or control elements is selected for entry into said data entry system.

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.

4. An order entry system comprising:
-
a display having order entry elements and control elements positioned on said display and lighting means to light up said order entry and control elements when selected;
each said order entry element and control element having a detector associated therewith;
said display also having a first display area for indicating the number of units of each said order entry element which is selected and the monetary value of the units selected;an aiming selector having means for emitting first and second light signals at said order entry elements and control elements which are to be selected; control means for controlling the operation of said order entry system; said control means including means coupled to said detectors for producing first and second outputs in response to said first light signals and said second light signals, respectively, falling on said detectors; said first output being used by said control means and said lighting means to give a first indication that said aiming selector is directed at a particular one of said order entry elements or said control elements, and said second output being used by said control means and said lighting means to give a second indication that said particular one of said order entry elements or said control elements is selected; and said control means also including means for totaling up the monetary value of all the order entry elements selected. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A method of selecting an item from an array of items, with each item having a light detector and a source of light associated therewith, said method comprising the steps of:
-
(a) aiming a ray of light having a first level at an item to be selected so as to actuate the associated said light detector; (b) using the output of the light detector from step a to switch said source of light for said item from step a to a first state which indicates that said item is targeted for selection; and (c) switching said ray of light to a second level while said source of light is in said first state to actuate the associated light detector to switch said source of light to a second state which indicates that said item which was targeted for selection is selected.

12. In an item ordering system, the method of ordering items at a fast food restaurant comprising the steps of:
-
(a) presenting items to be ordered on a menu which contains an array of said items and also contains control elements for controlling the operation of said system, with each said item and control element having a light detector and a source of light associated therewith; (b) aiming a ray of light of a first level at an item to be ordered to energize the associated said light detector causing the associated indicator to indicate that the item is targeted to be ordered; (c) changing the ray of light to a second level while aiming at said item which is targeted to thereby order said item; (d) repeating steps b and c, if necessary, until the ordering of items is complete; and (e) repeating steps b and c for a control element to control the operation of said ordering system. - View Dependent Claims (13)
