Client

A campus locator is being designed for use by new or prospective students, faculty, staff, or visitors at ISU to find locations of interest and navigate around the campus and its nearby environments. The campus locator will guide the user to various locations, both outdoors (e.g., buildings or points of interest) and indoors (e.g., classrooms, faculty or departmental offices, etc.)

The cell phone is envisioned as an I/O terminal, providing the campus locator user with access to a centrally-located database and central processor. Current cell phone capabilities, such as text messaging and Internet accessibility, as well as predicted capabilities, such as voice recognition will be considered.

Abstract

AcknowledgementsThe team would like acknowledge Dr. John Lamont & Prof. Ralph Patterson III for their generous contribution to the project.

Operating Environment User

Any environment that a cell phone can operate properly.

System The server will be in a heated and air conditioned environment.

Assumptions Continued interest in implementing the on-campus locator system from one or more campus groups Availability of funds at the implementation stage Only used for on-campus sites

Limitations Lack of experience in cell phone programming Lack of experience in voice recognition systems Only using basic cell phone services to appeal to larger audience (Text Messaging & Voice)

Assumptions and Limitations

Problem Statement To make it easy for new students and visitors to quickly and accurately navigate around campus To provide accurate simple navigational directions in the following forms

Shortest path routes Indoor routes Outdoor routes Scenic routes Bike paths Roads

The campus locator would provide easy navigational step-by-step directions to persons seeking them. Additional information such as that of parking, offices hours of faculty and staff, building information and bus routes will be provided. The user will connect to the system through a cell phone.

Closing Summary

Deliverables Specifications report: - specifies how the system works Final report - details on the implementation of the system.

Technologies Considerations

Proposed Approach Research and gather information on the following

Shortest path algorithms Voice recognition systems Software and hardware interface

Create a small demo based on research Get feedback from faculty and advisor Provide a detailed report of the outcome

Software Language Java/ JDBC Java/ SQLJ Windows/ C/ C++/ ODBC

Database management Oracle Windows/ MySQL Linux/ MySQL/ PostgreSQL

Shortest path algorithms Dijkstra’s single source algorithm Bellman-Ford algorithm

Project Requirements

Design Objectives Must be cost effective Provide precise navigational directions Maintenance should be easily made Must be easy to use

Functional Requirements Calculate directions in real time Provide information of faculty offices, office hours, parking.

Design Constraints Documentation must be done by May 2006 Project must be cost effective Clear and precise directions

Measurable Milestones Project plan Design document Design review Requirements document/final report
