A few days ago, a relatively unknown company called IO2
the Heliodisplay M2 and M2i displays. The M2 is unique in the fact
that it creates a non-holographic image projected into mid-air. Without a
point of reference, the Heliodisplay appears to be 3D, giving the viewer the
illusion of a floating holograph. The two models announced today are
capable of creating images approximately 30" across diagonally.
With drivers provided by IO2, the display plugs into a USB port and the screen
interaction and display is handled all inside the unit. Currently, the
Heliodisplay can achieve SVGA resolutions (800x600) with resize support up to
1280x1024. IO2 claims a contrast ratio of 2000:1, but since the
technology is effectively rear projection onto a wave of hot air, direct
sunlight or lots of ambient light will distort or wash out the image.
The touch sensitivity of the screen allows for users to interact with the
display in real time, which can then be relayed to a computer or some other
USB-ready device. IO2 claims the device is perfect for everything from
medical imaging to teleprompting to HUDs. The projector is relatively
bulky, weighing in at about 35lbs, but can be built into tables or walls to provide
that true Minority Report feel.
This is actually IO2 Technology's second mid-air display. The M1 was
significantly smaller than the M2 and significantly louder. The M2 and
M2i are rated at 38dbA, and uses about 350W during operation. Pricing of
the M2 and interactive M2i was not announced.
