Interactive whiteboards in detail
 

The disadvantages

  • Interactive whiteboards are more expensive than conventional whiteboards or projector and screen combinations
  • The surface can become damaged, requiring expensive replacement
  • Front projection boards can be obscured by one or more users
  • Fixed-height boards are often mounted too high for users to reach the top of or too low to be readily visible by all users
  • Free-standing boards (and their associated projectors) are more difficult to secure and need to be realigned every time they are moved
  • If multiple data entry is allowed, inputs can get jumbled, resulting in on-screen gibberish
  • If remote access is allowed, some users may be tempted to send disruptive comments or drawings to the screen
