3. Project Overview Location tracking system using personal server attached to a cricket listener as a “mouse” to interface with a data projector display in Sieg hall

4. Design Overview

5. Usage Scenario Sieg Hall Data Projector Many people will have these personal servers. If you are one of those lucky people, you can control the display Forward and Backward slide show capabilities Section Selection

6. Projector Display CSE Department Announcements CNN News Headlines Today’s CSE Events Slide Show Colloquia Slide Show Message Board Demos Traffic/Bus Information

7. Major Components Projector Projector Server Personal Server Cricket Listener and beacons

8. Major Components ~ Projector The projector will sit in Sieg hall near the 1 st floor landing. It will be attached to the Projector Server. CSE Department Announcements CNN News Headlines Today’s CSE Events Slide Show Colloquia Slide Show Message Board Demos Traffic/Bus Information

9. Major Components ~ Projector Server Projector Control program Cricket data to Command Program Communicates to Personal Server via Bluetooth

10. Major Components ~ Personal Server Gathers Data from Crickets Formats data to packets and sends data to Projector Server Gets cricket data via serial cable to cricket listener

11. Major Components ~ Cricket Listener and Beacons Uses Ultrasound to measure distance Beacons Chirp randomly at approximately 3 times per second Listener gathers data from each beacon and outputs in raw ascii the distance and beacon code
