Project Overview

• Presentation attendees often have questions or
  concerns that are complex 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 75.00 per unit
• Cost jumps to 275.00 if using an eBox 3300

Design Objectives Initial Goals

• 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
• Easy to use

Technical ApproachDesign Method

• Interpretation
• eBox 3300 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)
• Utilizes Brian Peeks C WiiMote Library (1)
• Projection
• C application displays fully-transparent, blank
  program window overlay
• Draws operation information to screen

Modes of OperationStandard Drawing

• Holding B trigger enables drawing mode.
• Pressing A button clears the screen.
• Holding A button enables pointing mode.
• Pressing Up Down changes the marker color.
• Blue, Red, Black, Yellow, White
• Pressing and changes the marker thickness.
• Pressing Home resets to default settings (medium
  blue marker)

Modes of OperationPowerPoint Integration

• Pressing Left Right changes the current slide.
• Utilizes the SendKey class in C
• Pressing 1 and 2 simultaneously exits the
  program.
• Possibility of future features as well
• Utilize accelerometer to change slides
• Add rumble features
• Utilize on-board speaker

Possible Future Work

• Integrate functionality into a single system
  (DONE!)
• Reduces need for additional computer and
  projector
• Erases need for supplementary networking
  components
• Reduces cost
• Add user-controlled gestures to interact with
  software (Partially Done!)
• User can switch slides using button presses
• More gesturing 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
