INTERACTIVE+WHITEBOARDS

**What is an interactive whiteboard?**
An **interactive whiteboard** (IWB) is a large display screen that is connected to a computer and projector to become an interactive device. Users can control the computer using the whiteboard. It replaces traditional dry erase boards and overhead projectors.

**Where was it invented?**
A Canadian company, SMART Technologies, invented interactive whiteboards in 1991. Other companies have jumped on the bandwagon and developed their own boards, but SMART boards remain the top selling brand, and their name has basically become synonymous with the technology.

**How does it work?**
An interactive whiteboard can either be mounted on a wall or used on a floor stand. Software is installed on the computer that works with the IWB, making it a user interface. A projector projects the computer’s desktop onto the board’s surface, users can control the computer from the computer terminal itself or directly on the IWB using a special pen or even simply a finger. The software that comes with the board can also make the board act like a traditional whiteboard which students and teachers can write notes, examples, etc. The work can then be saved digitally, unlike work done on a traditional whiteboard. Systems commonly use front projection, but can use rear projection to eliminate shadows. Educator can use the IWB instuctionally to show and control videos, PowerPoint presentations and webpages along with other software programs. Students can also be active participants in lessons directly using the IWB. media type="youtube" key="DjdNPMZJbLs" height="344" width="425"media type="custom" key="3225224"
