The Office of the Dean of Students December 20, 2003 Projects: 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

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
