Requirements Problem Statement Operating Environment Intended Users and Uses Assumptions and Limitations Expected End Product and Other Deliverables

Problem Statement To develop a system that will greatly reduce the amount of paper that a restaurant uses.

Operating Environment To be used indoors Stored indoors

Intended Use and Users Use – To take orders – Payment of orders – View orders to cook Users – Servers – Cooks – Managers – Customers

Assumptions Products already exist Product will not be state of the art The end product will not be small 12 handhelds to be used at once Bluetooth range is 10m There will be 5 simultaneous transmissions Handhelds recharged throughout the day Central Computer located centrally in the restaurant. Model can be developed into a handheld.

Limitations Wireless and Bluetooth distance Power supply Memory and processing speed Size of the monitor for the kitchen The cost of the items for the project The lack of programming skills of the group

Expected End Product and Other Deliverables Handheld Device Computer Monitor Wireless Printer Central Computer Software – Handheld – Central Computer Database GUI Model

Central Computer Approach Used Hardware Design Software Design

Approach Used Design Objectives – Applications must run as smoothly as possible on the computer. – Easy to use and understand right from start-up. – Needs to run without error at all times. – Graphical interfaces must be very simple and professional-looking.

Approach Used (cont.)

Functional Requirements – Inventory and order history – Graphical user interface – User-created menus – Kitchen-based display – Communication with the handheld

Approach Used (cont.) Testing Approach Considerations – Ability to create and edit menus – Ability to view/edit inventory and order history – Effectiveness of graphical user interfaces – Ease/difficulty in understanding how to use applications – Wireless communications with the eBox-II – Proper kitchen display – Overall practicality of using system in a restaurant environment

Hardware Design Dell GX270 – Processor – Intel 865G chipset – Memory up to 4 GB – Ethernet – Eight USB 2.0 – keyboard/mouse – Video Controller – Power Supply

Hardware Design (cont.) Linksys BEFW11S4 Wireless-B Broadband Router – Standards: IEEE b – Protocol: CSMA/CD – Channels: 11 (US, Canada) – Ports: Internet/LAN: RJ-45 – Speed: 10/100Mbps (Half Duplex) 20/200 (Full Duplex) – Cabling Type: UTP Category 5 – Dimensions: 7.31" x 6.16" x 1.88“ – Unit Weight: 16 oz. (0.45 kg) – Power: External, 5V DC, 2A

Software Design Networking in the Java Application

Software Design (cont.) Database – MySQL database system, with databases for the following: Restaurant inventory Order history Each menu created

Software Design (cont.) User Interfaces – Manager interface – Kitchen interface

Software Design (cont.) Simultaneously, the system will allow the user to create/edit menus and view/edit order history and inventory

Software Design (cont.)

Recommendations Regarding Project Continuation/Modification Project Continuation Project Modification – Handheld – Central Computer

Project Continuation Handheld – Secure wireless communication with VPN – Give ability for server to sign-in and out of the handheld – Create a prototype – Make the GUI more robust by including all available possibilities of a dish Central Computer – Add a VPN server to the central computer – Create a more robust database – Create a more robust GUI

Project Modification Handheld – Replace the HDK with an eBox-II due to expense – No touch screen due to use of eBox-II Central Computer – No change to the design necessary

Summary Device will not be a marketable product Concept will be proven Servers will carry a wireless handheld device: – place orders – receive payments – print receipts Device will include: – LCD touch screen – magnetic card swipe – Bluetooth printer This will reduce paper used and increase efficiency. Restaurants may find the idea of this device to be an attractive option.
