DESCRIPTION OF PREFERRED EMBODIMENT
Referring now to FIG. 1 there is shown a typical prior art vending machine 10 with display window 12 through which a potential purchaser may view the products 14 for sale. The products 14 are held in a series of rows and columns and upon selection by pressing a key in the keypad 16 and making payment through the slot just below pad 16 are dropped down into compartment 100. Frequently a pre-selection keypad 20 and display screen 22 allow the customer to receive information about a selected product before making the decision to buy with keypad 16.
In FIG. 2 there is shown a simplified vending machine 30 according to the present invention. While for illustrative purposes I use herein a vending machine for food items (i.e. snack and drink) a vending machine according to the present invention could dispense a wide variety of items such as medicines, personal hygiene items, sundries, books and the like. Further this viewing and selection method and apparatus can be applied to a wide variety of investigation, selection, processing and action environments where the user can confirm an exact item condition and content before initiating an action relative thereto. Typical such environments include “build your own” sandwich, toy or the like selection and even assembly operations where real time observation and activity are required.
In vending machine 30 food and drink products 32 are again stored in the usual rows and columns and are viewed through a display area window 34. Mounted on display window 34 are a series of transparent touch screen units 36 one for each displayed product. In FIG. 3 the units 36, shown in partially exploded form, each consist of display layer 36c, touch screen layer 36b and protective layer 36a. Each unit 36 provides a direct view of one product group in its row and column. Units 36 each have “information” and “selection” areas 38 & 40 respectively formed on each touch screen unit 36 to permit customer control of viewing the products, selecting which products to get more information about and initiating purchasing action directly while looking at a desired product. Touching the “info” area 38 will display the dietary or other product information for that particular product at 42 on the touch screen unit 36 for the customer's review concerning the product of interest. The product information and selection functions can thus be accomplished with minimum customer effort or distraction from multiple complicated operating devices and instructions.
Should the information displayed result in the product selected being unacceptable the customer need only move to the next unit 36 and associated viewable product without having to start over at a separate keypad location elsewhere on the vending machine thus retaining the efficient direct and compact operating ease of the transparent touch screen units 36.
As soon as the customer is satisfied with the product information displayed and decides to buy the product he merely touches the “select” area 40. The selection is noted in CPU 60 and the transparent touch screen then in display area 42 offers the customer payment options such as coin, pliant currency, credit card, or other payment method with suitable indicia displayed on the appropriate information display screen 42 as appropriate. The customer again with the transparent touch screen unit 36 using display screen 42 merely touches the preferred payment method of those offered and after the CPU 60 via payment input unit 68 verifies payment has been received the product is released to the compartment 46 in the machine 30.
All of this activity may of course be recorded and saved by the microcontroller 50 (see FIG. 5) for inventory control, preference survey, purchase activity or other purposes.
Referring now to FIG. 4 the entire display window area 34 of FIG. 3 comprises a transparent touch screen 80. Typically this would include display layer 80c, touch screen layer 80b and protective layer 80a. Touch screen 80 would have indicated individual display areas 82 opposite each group of product to be dispensed with protective overlay indicating the viewing 42′, information 38′ and selection 40′ areas for each item stocked in the vending machine similar to that shown in FIG. 3. Transparent touch screen units 36 and 80 may be OGLED or LED units as desired.
FIG. 5 shows in block diagram form, the microcontroller 50 control system for accomplishing the above described item viewing, selection, and delivery, method and apparatus. A central processing (CPU) module 60 has operatively connected thereto suitable memory 62; one or more data bases 64, containing the information and data needed for the supply of items to be selected; internet access means 66; payment processing means 68; and of course connections to the LED transparent touch screen units display and input means 70 and 72 respectively.. Other functions as needed can be added to the microcontroller 50 which is imbedded within the vending machine 30.
Referring now to FIG. 6 vending machine 30′ in addition to the transparent touchscreen units 36′ is provided with, at the top of display area 34′, a gesture recognition window or camera 102. Microprocessor 50 in addition to the functions shown in FIG. 5 would have the program “other” connected to the CPU 60 and gesture recognition window 102 to recognize various arm and hand motions seen by the recognition window 102 as commands to the vending machine 30′ for performing the desired information gathering, product selection, compensation and dispensing functions. These motions could be unique to this application gestures, or they could be merely American Sign Language (ASL) letters to spell out a password or command. This embodiment is especially helpful for users who have various limitations or handicaps that make use of the touch screen capability difficult or inconvenient.
In FIG. 7 there is shown a gesture recognition unit 102′ positioned at the top of display window area unit 80′ in a vending machine 30′′ essentially the same as in FIG. 4 with touch screen 80′ having display layer 82C′, touch screen layer 82B′, and protective layer 82A′ also. This adds gesture recognition to the vending machine shown in FIG. 4 and described above.
While there are given above certain specific examples of this invention and it application in practical use, it should be understood that they are not intended to be exhaustive or to be limiting of the invention. On the contrary these illustrations and explanations herein are given in order to acquaint others skilled in the art with this invention and the principles thereof and a suitable manner of its application in practical use.
