Design ReviewNovember 11, 2003

• Projects
• Interactive Campus Map (ICM)
• Adjustable Book Shelf (ABS)
• Global Positioning System Device for the Visually
  Impaired (GPS-DVI)

2
ICM
Interactive Campus Map

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

3
Group Members

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

4
Semester Goals

• Install functioning Kiosk in MSEE Building
• Expand area, and plan improvements
• Better map images
• Actual distance calculations
• Voice recognition synthesis

5
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

6
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

7
Nodes in the Map
8
Node Database

• Database example
• For GPS coordinates (Latitude, Longitude)

9
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

10
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)

11
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

Adjustable Book Shelf

• Team Members
• Sandeep Nandy (Project Leader)
• Ankit Dhawan Vineet Alva
• Shohei Shibata Rayelle Duncan

14
Agenda

• Timeline
• Design Parameters
• Turn Shelf Concept
• Slide Down Concept

15
Timeline
16
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

17
Turn Shelf 3-D view
18
Turn Shelf Side View with dimensions
19
Turn Shelf Accomplishments

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

20
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

21
Slide Down Bookshelf Design

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

22
Accomplishments

• Basic mechanisms and components of the bookshelf
  has been designed
• CAD drawing and dimension drawings are complete
• Capacity and loads have been approximated

23
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

24
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

25
GPS-DVI

• Global Positioning System
• Device for the Visually Impaired

• Team members
• Guneet Chadha
• Sivanit Ratanadib
• Ryan Hicks
• 4. Howard Lityo

26
Introduction

• GPS-DVI Team project that involves the
  development of a handheld device, incorporating a
  PDA with a GPS receiver which will aid students
  who are visually impaired in navigation around
  the campus.

Overview

• Project partner meeting
• Creation of Sub-Groups
• Assimilation
• Research
• Current State

28
Project Partner Meeting

• Requirements of the device
• Interact with GPS reciever
• Voice output
• 90 degree turns
• Tactile overlay
• Telephone like keypad
• Shortest Path Algorithm

29
Creation of Sub-groups
30
Assimilation

• Retrieval of equipment
• Determine previous work accomplished
• GUI
• Building codes
• Device driver (does not compile)
• Determine work to accomplish
• Device Driver
• Algorithm
• Voice Output

31
Research

• Met with EPICS Mobility TAs
• Explanation of how to use Microsoft Embedded
  Visual Tools 3.0
• Suggested that we buy device driver (dll)
• Researched GPS Receivers
• Teletype 1358 (no dll exist)
• Received manual
• Teletype 1658 (a dll exist)
• Pretec Compact GPS Compact GPS-LP
• NavRoute HP-610PC (no dll exist)
• TextAloud MP3

32
Current State

• We have obtained our PDA!
• Verified working function of GUI
• Received streams of GPS data
• Configuration of GPS receiver in progress
• Plan to integrate building codes with GUI
• Continue to debug the device driver code from
  Fall 2002
