1. Handheld Campus Tour Guide Michael Boyer Advisor: Professor John Spinelli

2. Outline Project motivation Design requirements Localization System design Future work

3. Project Motivation Tours offered to prospective students: –Student-guided tours –Self-guided tours: Goal: Create a system that will replace and improve upon the self-guided tours

4. Functional Requirements Localization accuracy: –Ten meters outdoors –Five meters indoors (in selected buildings) Visual representation of location Contextual information

5. Non-Functional Requirements Price: less than $1,000 Size: handheld Power: –Rechargeable –At least two hours per charge Easy to use

6. Localization Need to determine the location: –In real-time –In three-dimensions –Both indoors and outdoors GPS GSM

7. GPS Global Positioning System Satellite-based localization Available outdoors worldwide Not available indoors

8. GSM Global System for Mobile Communications Most widely used cell phone standard Available indoors and outdoors Designed for voice transmission, not localization…
