Interactive Whiteboards are often refered to as Smartboards. Smartboards are the "Kleenex" of the industry. Smart Technologies is the brand that boards smart boards or interactive whiteboards. Smart makes a few different types of interactive whiteboards. Here is a summary of some of the differences:
Smart Interactive Whiteboards
There are touch sensitive boards. For a general review and demo of the most popular 600 series smartboard, please check out this video of the SB680 which is 77inches. Smartboard Interactive whiteboards range from 48" to 94". Touchboards sellers larger size boards in other brands as well. Listed below ia demo video fo one of the more popular models which show the stardard smart Interactive whiteboard technology.
Other than the size differences, Smart Technologies has several combo systems which include a short throw projector. These are all in one systems. Please check out the different systems as you look at these boards.
Smart Interactive LCD/LED
Smart has overlays as well as complete LCD systems. A smart overlay goes overtop a current LED/LCD or Plasma system. These type of units are not as popular as they once were. They require you to install them over the screen and this sometimes can cause issues with the install. The units which have become more popular over the last 2 years are the complete Interactive Screens. These are a LCD monitor with the interactivty built into the system already. These units have no shadow as they do not need a projector. They are true interactive televisions. The downside is they are more expensive than the standard smart interactive whiteboards.
