• Objective To help students with physical
  disabilities locate the best accessible path
  between campus locations
• Can also be used by visitors

How does ICM work?

• User gives start/end information on website
• Calculate shortest path
• Draw map
• Encode Image
• Display

5
Last Semester

• Smaller partly working map
• DEMO!!!!
• Able to integrate bigger campus map
• Problems with the path drawing
• Extended the campus coverage

6
Semester Goals

• Improve path drawing
• Expand area, and plan improvements
• Resize existing map
• Add the Cropping function to the software

7
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

8
Nodes in the Map

Node Database

• Database example

10
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

11
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

12
Project Partner

• Updated the Project Partner about the current
  status
• Informed about our delivery plans

Adjustable Bookshelf Project

• Members
• Shohei Shibata
• Vineeth Alva
• Ankit Dhawan

18
Project 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.

19
Constraints

• ADA guideline
• Height Range 9 to 48
• Forward Reach up to 25
• User inserts 5 lbs of force maximum.
• Dorm room space limitations

20
Design

• 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

21
Design

• 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

22
Accomplishments

• 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

23
Timeline

• Spring 2004
• Concept Generation, Selection
• Design sliding shelf, motor mechanism
• Construct prototype of sliding shelf
• Fall 2004
• Finish designing motor mechanism, control
  mechanism
• Complete, and test prototype
• Contact University Residences for placement of
  the shelf
• Delivery

24
Conclusion

• 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

27
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.

28
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

29
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
