Agenda List of Accomplishments in Fall 2003 Design Parameters Slide Down Concept Plans for this semester

Past Accomplishments New project was established Problem defined, design parameters set Concepts designed Ideas were eliminated down to one concept

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

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.

Semester Plans Reconsider concept from past semester –Cost analysis (must be under $500 per shelf) –Practicality: Is an easier solution achievable? Construct several other concepts Decision Matrix: make 1 st and 2 nd choices Create mathematical models, 3-d models List materials and complete cost analysis

ICM Objective: To help students with physical disabilities locate the best accessible path between campus locations by drawing a map Interactive Campus Map

Phase of the Design Process We are currently in the production phase - Kiosk mostly completed No more costs in the project - Everything has been purchased

Semester Goals Install functioning Kiosk in MSEE Building Expand area, and plan improvements Resizing existing map Turn by turn directions Actual distance calculations Voice recognition & synthesis

Tasks Obtain more GPS coordinates to complete the campus coverage Develop a method to crop the map for faster loading Write code for turn by turn directions Improve path drawing algorithm

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
