Jeff Turkstra – Project Leader / Programmer Abdul Zahid – Technical Programmer Avirul Sharma – GPS coordinator Vishnu Jaju – Graphic Designer/Multimedia

Semester Goals Install functioning

Kiosk in MSEE Building

Expand area, and plan improvements Better map images Actual distance

calculations Voice recognition &

synthesis

Initial Tasks Kiosk has to be picked up from machine

shop and building services contacted regarding installation - DONE

Computer Kiosk has to be configured and setup for user access - DONE

Obtain more GPS coordinates for all of campus - PARTIALLY DONE

Get user feedback – Plan new features - PARTIALLY DONE

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 For GPS coordinates (Latitude, Longitude)

Node Name GPS 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

Kiosk is ready (but ICM software is still “under construction”)

Larger, more detailed map integration is in progress

Coverage area has been significantly expanded over last semester

Resolved compilation errors with core source code

Coverage Area

Engineering Mall (from last semester) Area surrounding (and including) BRNG,

MATH, and CL50 Clock tower area (SC, CS, PSY) “Chemistry” area (WTHR, BRWN, GRIS,

HEAV, etc)

Prototype Ideas

Work has been done on planning methods to interface with GPS-DVI

Theoretical design for mysql driven PHP interface permitting the “posting” of current GPS coordinates and destination coordinates to the server, which would in turn generate and send back a map with text based turn-by-turn directions

Agenda

Timeline Design Parameters Turn Shelf Concept Slide Down Concept

Timeline

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

Turn Shelf 3-D view

Turn Shelf Side View with dimensions

Turn Shelf Accomplishments

Dimensions and clearances determined CAD models completed Book Capacity determined (12 books 2” thick) Max weight it will experience ~50 lbs

Turn Shelf Uncertainties

Use of Motor with belts Pros: Will require little or no muscular force by

user Cons: High Cost, higher chance of failure by parts

Use of flat metal coil springs Pros: Low cost, low risk of failure Cons: Anchorage of string, will require slight

initial force by user

Slide Down Bookshelf Design

•An adjustable bookshelf that fits inside the existing shelf.•Slides down at an angle onto the desk.

Accomplishments

Basic mechanisms and components of the bookshelf has been designed

CAD drawing and dimension drawings are complete

Capacity and loads have been approximated

Pros and Cons of Sliding Design

Pros More space Easier access Less complicated

motions

Cons Requires more forces Possibly requires

electrical assistance Noise Cost Space

Future Plans

Means of lifting the shelf back up needs more research

Safety Measures Counterweight idea is being considered Every component will be designed to more details Decision to be made on our final solution, as well as

contacting University Residences for their input
