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
Nodes in the Map
Node Database
Database example
Node Name X,Y Coordinates TYPE Neighbors
1 PHYS 6.285, 1.225 Door 2,4,9,10
2 MSEE(NW) 6.654, 3.256 Door 1,7,9,14
3 MSEE(SE) 6.542, 3.2545 Door 4,5,6
4 INT1 6.021, 3.021 Intersection 1,3,6
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
Engineering Mall Area surrounding (and including) BRNG, MATH,
and CL50 Clock tower area (SC, CS, PSY) “Chemistry” area (WTHR, BRWN, GRIS, HEAV, etc) Union Area (PMU, STEW, HICKS) Residence Halls (HILL, ERHT, HARR etc) Area around LILY, FS, AGAD etc
Project Partner
Updated the Project Partner about the current status
Informed about our delivery plans
DEMO!!!!!
Semester Timeline
Continuity Plan
Add new buildings to the database Research into other possible image formats Delivery (Week 4 of Fall’04)

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.

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
Weather Time of day
