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

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.
