1. The Office of the Dean of Students May 8th, 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

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

8. Nodes in the Map

9. 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

13. DEMO!!!!!

14. Semester Timeline

15. Continuity Plan • Add new buildings to the database • Research into other possible image formats • Delivery (Week 4 of Fall’04)

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.

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

31. Campus Map

32. Campus Database

33. Campus Map

34. Adjacency Matrix

35. Challenges • Compass heading unavailable • Unable to determine users current heading • Weather dependent • GPS receiver inaccuracy

36. Next Semester Plan • Expand Map Coverage • Add user customizable options • Type of voice outputs • Upgrade software to be compatible with Pocket PC 2003 PDA • Test system in a variety of conditions • Weather • Time of day
