The Office of the Dean of Students

December 20, 2003Projects:

Interactive Campus Map (ICM)Adjustable Book Shelf (ABS)

Global Positioning System Device for the Visually Impaired (GPS-DVI)

ICM

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

Team members Jeff Turkstra Abdul Zahid Avirul Sharma Vishnu Jaju

Semester Goals Obtain and configure Kiosk Expand coverage area Plan improvements

Better map image(s) Turn-by-turn directions

Actual distance calculations Voice recognition and

synthesis

Begin work on prototype GPS-DVI interface

How does ICM work?

User gives start/end information on website

Calculate shortest path Draw map Encode Image Display

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 on 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

Cool live demo!

Kiosk

This Semester

Resolved compilation errors with core source code (many simply related to updated g++ version)

Kiosk is ready Larger, more detailed map integration is almost

entirely complete Turn-by-turn instructions have been added, without

distance calculations Coverage area has been significantly expanded over

last semester

Current 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

What’s Left?

Dynamic map cropping/resizing (current map is incredibly large)

Improve path drawing algorithm on map Distance calculations with turn-by-turn

directions Install Kiosk Project should theoretically be completed next

semester

Agenda

Timeline Design Parameters Concept #1: Turn Shelf Concept Concept #2: Slide Down Concept Modification of Slide Down Future Plans

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

Book Capacity determined (12 books 2” thick) Max weight it will experience ~50 lbs The concept was not used for practicality

reasons: It only lowers the top shelf by 8”, not worth the complicated mechanisms

Slide Down Bookshelf Design

•An adjustable bookshelf that fits inside the existing shelf.•Slides down at an angle onto the desk.•It will contain about 120lbs of books when fully packed.

Slide Down Design Improvements

Garage Door Concept Dimensions are based on the

Tarkington and Wiley bookshelves

Shelf will be lowered in the same manner as a garage door using a small garage door motor.

Inside shell resemble “open” position of garage door.

Down on desk to resemble “Closed” position of garage.

Future Plans

Exact procedure and mechanisms for raising and lowering bookshelf

Safety Measures Research possibility of incorporating design to

be compatible to all of the dorms on campus Survey University Residences for their input
