DETAILED DESCRIPTION
FIG. 1 is a flowchart which shows a basic outline of the use of one embodiment of a device made in accordance with the present invention. In this embodiment, the device is a dedicated device that is provided to a consumer by a particular restaurant or store and can only be used with that particular restaurant or store. The device is handheld, has a screen for video (graphics, text, or animation) and a speaker for audio output as well as buttons for inputting. Alternative devices could have touch screens or microphones as other methods of input. (Obviously, other embodiments could have any combination of such elements without departing from the scope of the invention.) The device also has a radio transmitter and receiver.
In order to use the device, it first is activated as shown at 20. At any point after it has been activated, the device may be used for visual and/or audio advertising. This advertising material may come pre-programmed in the device, or it may be sent to the device via radio transmission. Alternatively, a combination of the two may be used; the device can come with a preprogrammed base of graphics and text, and updates can be sent to it periodically via radio transmission. For example, in the morning hours, the device could show advertisements for breakfast specials which could change to advertisements for lunch specials around lunchtime, either automatically as per programmed directions, or at the command of a radio signal.
This embodiment of the device contains both a lithium battery and a standard alkaline battery. The lithium battery powers the memory of the device (which should be preserved even when the device is off), and the standard alkaline battery powers the device when it is turned on. Of course, it will be obvious to those skilled in the art to use any suitable known power source.
Since this particular device works with only one restaurant, the user does not need to select the desired restaurant. (Other embodiments may require the user to select the desired chain of restaurants, or the desired restaurant within, a chain, as will be described later.) Once the user activates the device as shown at 20, the device verifies that it is within the desired range of its selected restaurant as shown at 22. This range may be programmed or changed depending on the individual desires of the restaurant or the user, but, preferably, it should be between one-half and five miles away or whatever distance will-offer the desired lead-time to the restaurant.
The device may determine its distance from the restaurant via one, or more of several methods. For example, the device may access a Global Positioning System to determine its latitude and longitude coordinates, and then compare those coordinates to those of the restaurant to determine its distance. Alternatively, it may triangulate its location by determining its signal strength to various transmission towers.
If the device is not within this range, then it will output an error screen 24 with some sort of appropriate message such as “out of range.” It may also make some sort of appropriate sound to notify the user that it is out of range and an order cannot be submitted. The device would then allow some set time interval to pass—in this embodiment, one minute as shown at 26—before again checking its location and range.
Once the device is within range of the restaurant, it will continue with the next step of the ordering system, presenting an ordering screen 28 to the user. Alternatively, the device could store orders before coming into range of restaurant, and then transmit the orders once the restaurant is within range.
The information on the ordering screen 28 could be transmitted to the device upon activation or could be stored in the memory of the device and periodically updated. This screen could be text-based but would preferably be mainly graphics-based. Images of the menu of the restaurant are displayed, and the user selects his order using a touch screen, stylus, mouse, keyboard, or other known means of selection. The user may customize his order, as well. For example, if the user selects a hamburger, he may then see another screen image giving him options such as what condiments he would like. For example, he could choose to include lettuce, onions, pickles, and mayonnaise, but no mustard or tomato slices. As the user makes these selections at 30, the device will acknowledge them, and may even show an appropriate animation. For example, as the user asks for lettuce on his hamburger, small cartoon lettuce leaves could fly into a cartoon hamburger on the screen. Because the user inputs all this information himself and can easily view, verify, and edit it, the device can be much more accurate than traditional oral ordering methods. This is especially important with large groups of people; a bus full of members of a tour group could pass the device around and all input their individual order accurately. All of the user's selections are stored in the working memory of the device as shown at 32. After the user makes his selection, the device outputs a question as shown at 34 to ensure that the user is finished making selections and is ready to transmit his order to the restaurant. If the user indicates that he is not ready as shown at 36A, the device 6 returns to the ordering screen for further input or editing. If, on the other hand, the user indicates that he has completed his order and is prepared to send it as shown at 36B, the system continues.
At this point, for security reasons, the user may be required to enter a security code or password as shown at 38. The user may pay by credit card or some other method as the order is sent to the restaurant's computer system as shown at 40, or he may pay at the restaurant when the order is delivered.
Once the restaurant has received the order, it sends a confirmation number and corresponding message to the device as shown at 42, which displays both on the screen. This concludes the basic process of using the dedicated device. At this point, the user travels to the restaurant to pick up his completed order. The device also may direct the user to the restaurant with audio and/or visual directions.
While this embodiment envisions transmitting the order to the restaurant via radio waves, using cell phone technology, another mechanism for transmitting the order would be via infrared transmission. In this case, the order could simply be stored in the device, and then the user could drive-up to a kiosk remote from the restaurant or at the restaurant itself, with the kiosk adapted to receive an infrared transmission, and transmit the order via infrared to that kiosk. The kiosk would be equipped with means to transmit to the restaurant by some known means, such as being hard-wired, by telephone lines, by radio transmission, and so forth. Of course, any known methods of transmitting electronic signals could be used for transmission of the order between the hand-held device and the kiosk and/or restaurant.
FIG. 2 is a flowchart which shows a basic outline of the use of another embodiment of the device. This device is similar to the previous embodiment in nearly all respects, but it is not dedicated to a single restaurant or other business. Instead, it operates with several different restaurants or businesses. Thus, after activating the device as shown at 120, the user must choose the restaurant chain from which he wishes to order, and, possibly (given the number of restaurants of that chain in the area) which specific branch of that chain. This selection is shown at 121. In order to select the desired chain or branch, the user will be presented with a selection screen showing him his various options, or allowing him to browse or search for a desired restaurant based on a variety of criteria. This information could be stored in the local memory of the device, or transmitted via radio signal. The device may also have access to data about the locations of the nearest restaurants, and may suggest a restaurant based on which is closest to the user or to a location that is entered by the user. Upon user selection, the device may then offer video and/or audio directions to help the user navigate to the selected restaurant. This information could be transmitted via satellite or cellular telephone towers, and could be tied to a Global Positioning System. Such a feature could be very useful for travelers; they could locate a restaurant, order, and be navigated to the restaurant, all with the same device.
FIG. 3 is a flowchart which shows the transmission of data throughout the ordering process. This embodiment of the system uses satellites to direct the radio signals which transmit the data. First, the user inputs restaurant and order information into the device as shown at 50. The device temporarily stores this information for editing, and may at any point, send information in the form of advertising back to the user as shown at 52A. Once the user is ready, the device sends the order information via satellite as shown at 54. This satellite directs the information to the receiver at the restaurant as shown at 56, wherein this data may be incorporated directly into the assembly line (human or fully-automated), and the order placed in a queue for filling. The system may also be optimized to determine the best location to put the order in the queue based on how long it takes to complete that type of order, and on the general location of the user. This location may be determined by the device via several methods as previously described, and transmitted to the restaurant's system with the order data. Such optimization would prevent food from being prepared too early or too late. Once the order is received, the restaurant's system may assign it an order number (or confirmation number) or other verifying message, and send this data back via the satellite (shown at 58) to the device (shown at 60) which displays it for the user as shown at 52B.
As the flowchart of FIG. 4 shows, however, other methods of data transmission may be used besides a satellite. As is the current standard for cellular telephones, a network of transmission towers could also be used with the device and system, taking the place of the satellite in the system of FIG. 3.
FIG. 5 is a flowchart which shows another embodiment of the system. This embodiment of the system would be used in a situation where the device works with a number of restaurants. In this case, the system is organized through a central hub rather than going directly to the restaurant. In this system, the user again begins by inputting the restaurant information, order, and payment information or password into the device as shown at 250, which then sends the information via satellite or other sending means, such as a tower to a central hub as shown at 254 and 255, respectively. The central hub then sends the information and customer payment via satellite or tower (257) (in some cases the same satellite or tower may be used) or some other transmission means to the appropriate restaurant (as shown at 256), where it is accepted into the restaurant's ordering system as in the previous embodiments. In this system, the central hub sends confirmation messages back to the device and user as shown at 253A, 253B, and 253C, though the restaurant could do this as well.
This system could also work with ordering from multiple restaurants, as is shown in the flowchart of FIG. 6. For example, the user may order a meal from one restaurant, a beverage from another restaurant, and a dessert from a third restaurant. The system begins when the user inputs the appropriate order and payment information into the device as shown at 350. The device then transmits the data wirelessly via one or more satellites or other transmission means to the central hub as shown at 354 and 355, respectively. The central hub then sorts the order into the three sub-orders, and transmits them via one or more satellites (357) or other transmission means to the various restaurants as shown at 356A, 256B, and 356C. From there, the system continues as it has in previous embodiments; the central hub or the restaurants could transmit a confirmation number of message to the user as shown at 353A, 353B, and 353C, and the user need only go to the various restaurants to retrieve his order. As in the other embodiments, this system allows the device to be used as an effective advertising tool. The restaurants could communicate through the central hub to have the device output visual or audio data to the user about menus, specials, locations, directions, pricing, or other relevant information. Alternatively, such information could be preprogrammed into the device.
This device and system would be applicable in many different settings, including bagel shops, coffee shops, tea shops, donut shops, fast food restaurants, delis, restaurants, ice cream parlors, etc., and may even be used in other applications outside the food industry.
