2. Concept & Motivation Create an interactive, collaborative experience for Disney Parks using "magic wands" that can communicate with one another and a coordinator to play games, draw digital images, participate in voting, and allow for park-wide guest tracking. Develop a network of low-cost end user devices and base stations connected by a low-power wireless mesh standard. Now: Long lines, boring waiting times, low interaction Not a very “magical” experience After: Environment of collaboration and involvement Virtual doodling Event voting Interactive group games

3. Competitive Analysis H-ITT Clicker (http://www.h-itt.com/) Used in education for in-class participation Users must all aim at a common IR/RF receiver Can only be used to vote (up to 10 choices) Get-In-Line (http://getinlinegames.com/) Games and activities for making waiting in queues more enjoyable Currently in development at CMU's ETC Software only, uses cell phones Wiimote Smoothboard (http://smoothboard.net/) Turns a surface into an interactive whiteboard using a Wii remote as an IR camera Our system tracks multiple IR blobs

4. Requirements Functional Track 10 IR blobs simultaneously Send receive events over Zigbee Coordinate button presses and RF information with events Recognize gestures from accelerometer Set LEDs on wands Behavioral Network must not drop more than 5% of Zigbee packets Battery life of at least 1 week 100ft range outdoors Easy to carry around and safe for children Power saving mode – sleep when moved away from a coordinator Cameras should be able to process movement information and have image appear on screen in real time
