1. Little Brother Surveillance Nathaniel Brown & Chris Mordue

2. Basic Scenario Parent and young child in department store  Find lost child Meeting a friend at the mall  Locate friend Security guard  View surveillance cameras while on patrol

3. Architecture USB Webcamera FPGA Personal Server Bluetooth Cell Phone Webcam Pic

4. Expected effort Software Construction  USB controller  Image compression  Bluetooth communication using personal server  Cell phone user software Minimum functionality  Cell phone displays webcam images Desired functionality  User selects between multiple cameras  User can zoom on part of the image

5. Expected effort (2) The BIG unknowns  How to communicate with the webcam at the bit level  Using USB device controller as a host controller Contingency plan  Suggestions?

6. Related Work Related products or research projects  Linux drivers for webcams  USB device controller  802.11 webcams but not bluetooth Project Novelties  Webcam to cell phone communication  FPGA as a USB host

7. Burning questions How to communicate with the USB webcam? Can we make a USB device controller act as a simple host? More suggestions?

8. Evaluation How would you evaluate your project?  Can we communicate from webcam to cell phone? What performance tests are important?  How long does it take to send an image? What would you want to know from user studies?  Is this useful?
