How does ICM work?

User gives start/end information on website

Calculate shortest path Draw map Encode Image Display

Last Semester

Smaller partly working map DEMO!!!!

Able to integrate bigger campus map Problems with the path drawing

Extended the campus coverage

Semester Goals Improve path

drawing Expand area, and

plan improvements

Resize existing map

Add the Cropping function to the software

Web-Interface

Facilitates channeling of the user input data to the best path implementation routine

Simple and easy to use Easy to maintain for future semesters Accessible via home computers, not just

kiosk

This Semester Accurate Path Drawing – Done

Get coordinates for most of campus – Done

Cropping Function - Done

Kiosk – Ready

Faster map loading – Nearing Completion

Project Delivery – Week 4 of Fall 04

Coverage Area

Project GoalProject Goal

Problem Definition – The shelving unit in dorm rooms do not allow access by a wheelchair user.

Does not follow Americans with Disability Act guidelines.

To build a bookshelf which follows the ADA guidelines, and is reachable by a student in wheelchair.

ConstraintsConstraints

ADA guideline: Height Range: 9” to 48” Forward Reach: up to 25” User inserts 5 lbs of force maximum.

Dorm room space limitations

DesignDesign

Sliding Shelf – Prototype Completed Frame with bookshelf sliding in/out – final product will

have a third row of shelf and wheels to prevent tipping Uses motor to slide bookshelf – exceeds 5 lbs limit

DesignDesign

Motor Mechanism – In progress Motor moves screw which provides guided linear motion Cannot find one that provides 24 in. of linear movement Final decision not yet made

Control Mechanism – In progress Switch with forward and reverse capabilities. Speed Control

Use input from tachometer to measure rpm of motor Programmed microchip controls input to motor Safety – will stop when shelf hits an obstruction

AccomplishmentsAccomplishments

Concepts generated, and primary choice selected

Force Analysis Design of sliding shelf completed, worked on

designing motor, control mechanism Completed prototype of bookshelf

Prototype has sliding capability Completed code for control mechanism

TimelineTimeline

Spring 2004 Concept Generation, Selection Design – sliding shelf, motor mechanism Construct prototype of sliding shelfFall 2004 Finish designing motor mechanism, control

mechanism Complete, and test prototype Contact University Residences for placement of the

shelf Delivery

ConclusionConclusion

Project is moving forward Significant progress made on project Project Partner is satisfied with the design

The team will strive to deliver the project in Fall, and begin exploring possibilities of a new project.

Advisors: Prof. Pomeranz Prof. Subramanyan

Overview

Introduction Project Constraints and Requirements Semester accomplishments Conclusion

Introduction

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 : “Campus-NAV” software integrates

a GPS receiver and a PDA to help user navigate around campus.

Project Constraints and Requirements

User interacts with handheld device Phone Keypad Tactile Overlay User only enters destination

Device should calculate shortest path to destination

Turn-by-Turn direction Voice Output Compass direction

GPS-DVI System GUI

Semester Accomplishments

Able to receive and parse GPS-data in real time Collected GPS coordinates for map nodes Developed several functions

Off track algorithm Function to generate Left/Right or NSEW directions Current node detection Closet node to starting location

Voice Output Current Node Feedback Off track warning Turn-by-turn directions

Challenges

Compass heading unavailable Unable to determine users current heading

Weather dependent GPS receiver inaccuracy

Next Semester Plan

Expand Map Coverage Add user customizable options

Type of voice outputs Upgrade software to be compatible with

Pocket PC 2003 PDA Test system in a variety of conditions
