Project Overview

• Students often have questions or concerns during
  class that are complicated enough to warrant
  interaction with presentation materials
• New design utilizes a projector, Wii remote, IR
  Light Bar and some additional hardware to allow
  students or professors to interact with class
  presentations or whiteboards
• Estimated parts cost is 630 per unit

Design Objectives

• Capably interact with Wii remote hardware via
  Bluetooth
• Provide useful Smart Board features, such as
  multi-colored drawing, marking, etc.
• If time allows, utilize additional buttons to
  interact with PowerPoint software running on a
  separate desktop PC
• Make it easy to enable and disable to reduce
  distraction and clear the screen quickly
• Easy to use

Technical ApproachDesign Method

• Interpretation
• eBox 2300 reads input from Nintendo Wii Remote
  via USB Bluetooth adapter
• Reads user motions and button presses to
  determine operation mode and command (point,
  draw, erase, etc.)?
• Projection
• C/C application displays fully-transparent,
  blank program window overlay
• Draws operation information to screen

Possible Future Work

• Integrate functionality into a single system
• Reduce need for additional computer and projector
• Erase need for supplementary networking
  components
• Reduce cost
• Add user-controlled gestures to interact with
  software
• Student could use specific Wii signals to switch
  slides or erase board.
• Could be achieved using either IR or built-in
  accelerometers
• Projector-bot
• Add mobility to board-controlling projector and
  EBOX
• Could utilize Stinger or IRobot hardware
• Could allow for addition of supplementary
  Phidgets modules for increased functionality
