1. The Office of the Dean of Students May 8 th, 2004 Projects: Interactive Campus Map (ICM) Adjustable Book Shelf (ABS) Global Positioning System Device for the Visually Impaired (GPS-DVI)

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

3. Group Members Abdul Zahid Project Leader Programmer Avirul Sharma Programmer Brian Eng Programmer Saad Sami Programmer

4. 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

17. 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.

25. GPS-DVI Global Positioning System - Device for the Visually Impaired Ryan Hicks Bryn Nealis Howard Lityo Mike Alexander Sivanit Ratanadib Sak Mahasuverachai Advisors: Prof. Pomeranz Prof. Subramanyan

26. 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

30. 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
