The Low-Cost Alternative

Why buy an interactive whiteboard when you can transform a regular whiteboard into an interactive system for roughly half the price? That's the question being posed by Luidia, a San Carlos, California, company that produces a portable device called the eBeam, which renders whiteboard projections interactive. Also unlike most of its competitors in this space, Luidia works with partners: 3M, Hitachi, and NEC use Luidia's technology in their equipment. Between January and September 2008, Luidia sold 25,000 units.
