Mission: To provide services and programs that enable students with disabilities achieve a comfortable learning environment.

GPS-DVIGlobal Positioning System -

Device for the Visually Impaired

Overview

• Project Overview

• Last Semester Achievements– Campus Map– Integer-to-speech function– Distance in Feet– Path Recalculation– Human Subjects Testing

• Team Transition

• Meeting with the project partner

Project Overview

• Objective: To design and implement a portable device that will enable students who are visually impaired to navigate around campus with the use of the global positioning system.

• Solution: Program – “PUGuide”

– Integrates GPS receiver and PDA to help user navigate around campus using voice output.

GPS-DVI System GUI

Updated Campus Map

Integer-to-speech function

• Function was created to convert integer values to voice output

• Allows simple speech of any number

• Used in many areas throughout program– Confirmation of user button presses– Speaking calculated distance from next node

and destination

Distance in Feet

• Tells user how far she is from destination/next node on button press

• Accounts for curvature of the Earth– Important as campus

coverage expands

• Allows user to choose their own path if familiar with campus

Path Recalculation

• Allows user flexibility if obstruction exists in calculated path

• Strongly desired by project partner

• Allows for simple implementation of automatic/manual path recalculation

Human Subjects Testing

• Could not be completed because of certification requirements

• User testing will improve overall product functionality and provide first-hand feedback

Team Transition

• New members:

- Rohit Vankipuram

- Jay Gengelbach

- Jonathan Timura

• Members have read through old design note-books to update themselves on the current status of the project.

• Old members like Saad Sami.

Meeting with project partner

• First meeting last week

• Key components:

-Team required to prepare questionnaire

-Need a more efficient method to ask user

to input code

-Program with reference to what node the

student is close to

ICMICM

• Objective: To help students with physical disabilities locate the best accessible path between campus locations by drawing a map

Phase of the Design Process

• We are currently in the production phase

- Software is optimized, kiosk needs minor modification, delivery imminent

• Project costs: $50– 802.11b USB adapter for kiosk computer

Semester Goals• Prepare kiosk for

use and place in MSEE

• Collect feedback• Improve and

maintain system• Deliver Project• Create node

database software

Kiosk Alterations

• Installation of 2 brackets– One on the bottom to hold the monitor at the

correct level– One at the top of the monitor to secure it in

place– Screw holes already in place– No physical alterations to outside of kiosk

Node Database Software

• Facilitate the creation of a node database with a simple and easy to use GUI

• Can be used for GPS-DVI and other applications

• Will utilize Qt and Qt Designer

This Semester So Far

• Received all confirmations and approvals for kiosk placement

• Met with Project Partner to inform him of our plans for this semester

• Planned necessary alterations to kiosk

• Created rough layout of node software front end

Agenda

• List of Accomplishments in Fall 2004

• Design Parameters

• Plans for this semester

Past Accomplishments

• New project was established

• Problem defined, design parameters set

• Concepts designed.

• Completed code for controlled mechanism.

• Prototype was created.

Current Prototype

Design Parameters

• Cost less than $500

• Requires very little muscle force by user

• Hold at least 8 – 10 books

• Makes use of current dorm shelving unit

• All books are attainable from a seated position

Semester Plans

• Reconsider concept from past semester– Cost analysis (must be under $500 per shelf)– Practicality: Is an easier solution achievable?

• Construct several other concepts

• Decision Matrix: make 1st and 2nd choices

• Create mathematical models, 3-d models

• List materials and complete cost analysis
