In the restaurant business People eat with their eyes, Presentation is half of the experience. The simplicity and ease of access of a menu are the main things that facilitate ordering food in a restaurant. A recent survey showcased that various applications based on wireless technologies are already in use enabling partial automation of the food ordering process. In this paper, we discuss about the design and implementation of digital dining in restaurants using ZigBee Technology with the help of touch screen sensor, speech recognition module and a color graphical LCD to provide a user- friendly environment. The order can be placed by simply touching the available food menus or through speech commands using speech recognition module. The other dimension to propose this new system is to reduce need of excess manpower and to eliminate excess time spend on giving manual order through waiter and increase operator improve overall operational efficiency. This automated menu card system gains many advantages over traditional menu ordering system. Keywords: Digital dining, ZigBeeTechnology, Touch screen, GLCD, Speech recognition module. 1. INTRODUCTION Among the favorite premises restaurant is a place where people visit usually in search of good eats. While visiting such place people expect hospitality and service that should satisfy them, which has a great impact on business transaction in restaurant. The customer gets disappointed if the time taken by waiter for taking order is very long or due to human error the wrong order is served toother [1]. The restaurant menu has evolved from its humble beginnings on carte chalkboards and image-less print to today s detailed, colorful displays. With the emergence of digital tablets and user-friendly touch screen technology menus can move to a whole new surface. With this electronic menu, orders can be taken correctly the first time. This system cuts down the manpower for taking the order from the customer [3]. 1.1 Existing System In the existing system, services such as making reservations, processing orders, and delivering meals generally require waiters to input customer information and then transmit the orders to kitchen for meal preparation [4]. Although this procedure is simple, it may significantly increase the workload of waiters and even cause errors in meal ordering or small change requires the entire menu-card to be re-printed or in prioritizing customers especially when the number of customers suddenly increases during busy hours, which can seriously degrade the overall service quality. Since large manpower is required, this system is error-prone and is time consuming from a customer s point of view. 1.2 Proposed System The above mentioned traditional menu ordering systems are time consuming and susceptible to human errors which can be reduced but can t be avoided. Our aim is to develop a cost effective system which could work in small restaurants that are not willing to invest huge amount of money in these systems [5]. The newly suggested system is emphasized on increasing social interaction which is highly improved among users using a Digital display input, speechrecognition, a user friendly interface, simple navigation and low cost, increasing service range of wireless communication used and decreasing order processing time. This is done by efficient use of GLCD, Touch screen, ZIGBEE module, ARM micro controller and Speech Module. *Corresponding Author 644

PROJECT DETAIL A Touch screen along with Graphical LCD will be placed on each table. Now the GLCD will act as a menu card displaying all the items available in the restaurant. The available menus to be displayed on GLCD are programmed in ARM micro controller. According to customers requirement he or she will select menu item and quantity by touching on Touch screen placed above the GLCD. Instantly the order will be transmitted to through ARM micro controller to receiving module in kitchen. ZIGBEE module is used for communication between transmitter on the table and receiver in cooking department in restaurant [1]. Both transmitter and receiver contains micro controller. The ARM micro controller which is at the receiver section takes the order which is displayed on LCD along with user table number. The user can also request the order even through speech commands using speech recognition module. 3.

Two I2C serial interfaces, Two SPI serial interfaces Two 32-bit timers, Watchdog Timer, PWM unit, Real Time Clock with optional battery backup, Brown out detect circuit General purpose I/O pins. 3.2 Touch Screen and GLCD A touch screen is an electronic visual display that can detect the presence and location of a touch within the display area. The touch screen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or to networks as terminals [5]. Fig 2: GLCD The handheld ordering terminal implements human computer interaction by 128x64 GLCD and touch screen. There is a high performance GLCD Controller integrated on chip. CPU transfers pixel data to GLCD screen.[5] The terminal uses 4-wire resistive touch screen. S3C44B0X need sampling to judge whether a touch screen has been touched. FM7843 is a 4-wire resistive touch screen input controller integrated circuit which is widely applied to small portable devices battery powered. 3.3 Zigbee Module The ZigBee network is defined by the ZigBee Alliance and based on the IEEE standard, which is target data RF embedded applications that require a low data rate, long battery life and secure networking. It is intended to operate in the 2.4ghz unlicensed ISM band which is well suited for wireless ordering system. ZigBee module can be configured in star, mesh, and cluster tree network topologies. ZigBee Wireless network of restaurant which is configured in star topology [2]. In this routing topology, data traffic and network commands are routed through a central node. Peripheral nodes require direct radio contact with the central node. An ordering end device acted as a peripheral node in the network is an RFD, it have stringent requirements for low power and memory space. An IEEE Voice Recognition Module Voice recognition is a technology that able a computer to capture the words spoken by a human with a help of microphone. These words are later on recognized by speech recognizer, and in the end, system outputs the recognized words. An ideal situation in the process of speech recognition is that, a speech recognition engine recognizes all words uttered by a human but, practically the performance of a speech recognition engine depends on number of factors [1]. Vocabularies, multiple users and noisy environment are the major factors that are counted in as the depending factors for a speech recognition engine. 4. SOFTWARE REQUIRED A.

By using this technology help catering enterprises reduce the costs of human resources, improve work efficiency and leap forward from the external image to the internal service quality. In this wireless handheld ordering system there will be one center server (main section), and any number of slaves (customer section). In this the data from the different slaves will be transmitted to the main section (master) through ZigBee. In the customer section(slave) we have one, one ARM7 (LPC1768), ZigBee transmitter and at main section we have one controller ARM7 (LPC2148), buzzer, LCD, PC, ZigBee receiver. When the customer take seats and he orders the requirements by using GLCD on which the items are displayed in images format, and when the customer selects the item, the input from the touch screen will be sent to the controller the data from the controller will be in analog form and controller will convert the analog data to digital data by using in built ADC, the controller receives the data in digital form and according to user input the controller will display the data(images) on GLCD and sends the data to the ZigBee then it transmits the data to the main section ZigBee. Fig 4(a): Transmitter block. Fig 4(b): Receiver block The main section ZigBee receives the data transmitted by the handheld section ZigBee and sends the data to the controller as soon as the data has received, the controller is connected to buzzer, when it is made high then the buzzer will blow which indicates data has received and the controller in mean while display the data(order by the customer which) on the LCD is connected to the controller and the controller will send the data to different section of server and it will display the data on PC as table no. 6. RESULTS Fig 5(a): Transmitter Module Fig 5(b): Receiver Module After customer takes seats, the customer selects the item required from the menu displayed on GLCD, the customer selects the item using touch then the data will be send to the controller then the controller ask for the quantity required Copyright 2013 Published by IJESR.

7 then the customer selects quantity required displayed on GLCD then the controller receives the data and transmit the data to the main section through ZigBee and the main section will receive the data and displays the data on LCD data displayed on LCD contain the information like table no, item ordered by the customer and quantity required shown in Fig CONCLUSION Fig 6: LCD at Kitchen Section In this paper, a high performance-cost ratio wireless handheld ordering terminal is proposed, which is based on the hardware platform of ARM7, and ZigBeewireless communication technology. The ordering terminal has the advantages of simple structure, stable operation, low power consumption and friendly interface, thus it has bright market that can prove worthy in transforming the whole catering industry. It can also help in reducing child labor problem, which is a huge problem in countries like India. 8. FUTURE SCOPE Many improvements can be done in the proposed system like GSM, WIFI, Server based LAN can be used in place of ZigBee. CELL PHONES, TABLETS and TFT monitors in place of GLCD. ANDRIOD APPs can also be developed for the Menu in CELL PHONES, TABLETS for much interactive way for the customers and BILLING MODULE can be directly interacted to the customers E table.
