For years, Science Fiction television programs and films have featured holographic, three dimensional displays. While we are all familiar with the concept, I have to admit that I have never actually seen a 3-D display in action. In fact, I wasn't even aware of their real-world existence until I began researching for a topic to write about this week. When I discovered that IO2 Technology recently introduced their M3 and M3i three dimensional displays, I was both amazed and astonished. The M3 and M3i displays are part of IO2 Technology's Heliodisplay series and they are already proving to be very unique and interesting devices.The M3 and M3i, which cost roughly $18,100 and $19,400 respectively, connect directly to a computer and function just a regular LCD or CRT monitor would. The 30" mid-air display has the potential to play everything from DVDs to slide-shows, and if you spend the extra money for the M3i version, you can also control the mouse cursor directly by moving!
your finger through the floating display screen. Cool, eh?
