The eBeam Wireless Keyboard, when used with the Edge or Engage system, puts even more interactivity in the palm of your hand.  About the size of a smart phone, and boasting a full QWERTY keyboard, the wireless keyboard can be used by anyone with little to no prior experience required.  

The Keyboards works from a range of up to 33 feet away, so you should be able to stand almost anywhere in the room and be able to use it.  The QWERTY keyboard allows you to type in any open application.  There are controls for Page UP and Page Down that operate in presentation, web pages, and documents.   The blank area near the top with the eBeam logo is a touch pad so you can use that for mouse control, scrolling up or down a page, and selecting items.  You can even select a writing tool from the eBeam software and use the touch pad for basic annotations.
