Project Concept

• Concept The Virtual Whiteboard is a device that
  can display text messages from cell phones
  anywhere in the world. The product utilizes an
  LCD screen that can be updated over the 3G
  network, WiFi, or USB and can display desired
  messages with real-time updates.
• Motivation The current version of a whiteboard,
  where public information is displayed while you
  are away is neither accessible nor advanced
  enough for people's busy lifestyles. With the
  Virtual Whiteboard, you can communicate en masse,
  from anywhere with just a text message from your
  cell phone. This is the ultimate convenience for
  someone who needs to let other people know
  information without having to divulge private
  contact information.

Competitive Analysis

• Cell phones, but you need to give away your cell
  phone number, and have others cell phone numbers
  
• Twitter on cell phones, useful but not always
  practical and requires everyone you need to be
  subscribed
• Conventional black/white board, not accessible
  enough, not convenient enough for todays
  lifestyles
• Electronic Message Board, but the text can not be
  displayed all at one time and messages can not be
  sent to it from any other device
