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

3
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

4
How does ICM work?

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

5
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

Node Database

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

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

11
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)

12
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

13
Whats 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

14
Adjustable Book Shelf

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

15
Agenda

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

16
Timeline
17
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

18
Turn Shelf 3-D view
19
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

20
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.

21
Slide Down Design Improvements
22
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.

23
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
