Abstract: Many a times at hotels, we have to wait for the waiter to give our order for food. This creates problems in Hotels especially in weekends and festival seasons. The main intension of our project is to avoid such problems and to give solutions to those problems. In this, a virtual reality with a camera will be placed above every table. Whenever the customer comes to their table, they can select their desired order from the virtual reality screen. The food items can be displayed by their names or by the images. Whenever the customer selects the food item, the camera captures the selected item in the form of segments and this will be compared with the data base of the server system and sent to the LCD display present at the kitchen side via Zigbee module. Index terms: Virtual Reality, Zigbee module, PIC Microcontroller, LCD Display, Server system I. INTRODUCTION Hotels are one of our favourite premises where most of us enjoy our weekends and festival seasons with family and friends. The customers have to wait for ordering the desired items and wait for the ordered food. The major complaint from the customers would be their dissatisfaction about the services offered at hotels. This issue of being late could be solved by the advancement in the technologies of communication. Thus, this project focuses on solving these above problems. This names the system as Digital Ordering System at Hotels using Virtual Reality. Hence, this is an integrated system for enabling the customers to immediately make orders by their own. This will minimize the number of minutes to wait for meal serving. II. DESIGN AND HYPOTHESES A. BLOCK DIAGRAM Figure 1. Transmitter section This transmitter section consists of a virtual reality projector with a camera, server system and a Zigbee transmitter which is interfaced with the receiver section consisting of PIC Microcontroller, Zigbee receiver and LCD display.
Figure 2. Receiver section B. PIC MICROCONTROLLER PIC is a made by microchip technology, from the family of Harvard architecture microcontrollers derived from the PIC1640 originally developed by general instructions microelectronics division. The name PIC raised to as Peripheral Interface Controller. This system uses a PIC microcontroller kit which consists of power jack for the supply of 9V DC power. It consists of 5 ports say port (A, B, C, D and E) where the LCD is connected to port B. Crystal oscillator of 4MHz frequency is used to generate periodically oscillating signals. A regulator is used to control the flow of current and voltage. This kit consists of MAX232, an integrated circuits that converts the signals from RS232 to serial port for TTL compatible digital logic circuits. It acts as a level shifter which converts the TTL to BIN and BIN to TTL. interaction with mouse and keyboard which we are doing it on our daily basics. This is unnatural way, which forces us to adapt to the demands of technology. But the virtual does totally opposite. It allows someone to fully immerse in the highly visual world. Prototype analysis The advantage of this is, to enable an embedded system to design easily, quickly and seamlessly add with the microcontroller by UART to the application. It is easy to interact with the PC or Laptop by the USB Driver. By running the setup application, we can adjust the distance by viewing the camera image available in the PC or Laptop in which the optimize interaction can be done. Output Analysis: Figure 4. Virtual Reality Figure 3. PIC Microcontroller C. VIRTUAL REALITY Virtual Reality simply means a computer technology that use software to produce the realistic images, sensations and other sounds that reproduce a real environment, and stimulate a user s physical presence in this environment. Virtual Reality simply means the effective interaction of human and machine. This aims to move beyond the standards of Sl.no Name of Item Character 1. TEA A 2. CAFÉ B 3. VADAI C 4. DOSAI D 5. IDLY E 6. FISH F
Table 1. Output Character Analysis Whenever the image is touched, a single character will be directed to the UART. These images are continuously monitored and captured by the camera and send to the server system. The captured images are in the form of segments which are compared with the database and sent to the other end where the items are displayed on the LCD screen. Output model Table 2. Commands for function set Initially, LCD must be prepared properly before the character is need, has to be displayed. For this, the number of commands has to be provided to the LCD before inputting the required data. Sl.no Function Command 1. Entry mode 0x06 2. Display off cursor off 0x08 3. Display on cursor on 0x0E 4. Display on cursor off 0x0C 5. Display on cursor blinking 0x0F 6. Clear Display 0x01 Table 3. Commands for Cursor function Figure 5. Output view model of Digital ordering system at hotels using virtual reality D. LCD DISPLAY It uses a 20x4 LCD Display for displaying the ordered items. Sl.no Bit Function set Command 1. 8 bit 1 line, 5x7 0x30 The LCD doesn t know about the data or commands supplied to its data bus. It is the user who requires the content at its data pins are data or commands. For this if the commands are inputted then a specific combination of 0 s and 1 s has to be applied to the control lines so as to identify it is the command. On the other hand, if the data is inputted at the data lines the other combination of 0s and 1s has to be applied on the control lines to specify that it is a data. Ex: if Command: RS = 0, R/W = 0, E = 1/0 then Data: RS = 1, R/W=0, E = 1/0 2. 8 bit 2 line, 5x7 3. 4 bit 1 line, 5x7 4. 4 bit 2 line, 5x7 0x38 0x20 0x28
Figure 6. 20x4 LCD Display E. ZIGBEE MODULE This module consists of both receiver and transmitter which are defined by Zigbee alliance and data on the IEEE 802.15.4 standard. It has a long battery life, low data rate and secure networking. It is intended to operate in 2.4GHz unlicensed ISM band. Transmission range is up to 400m, which can meet the demands of wireless ordering system. It collects the data from the server system and sends it to the other end (i.e., LCD display via Zigbee receiver). Thus our project provides a way to reduce the customer s time for waiting to order their desired menu. This system is user friendly and fast which brings a change in the ordering system of a desired menu and making the dining experience more effective for the customers. IV.
