InFocus has introduced its third generation of interactive projectors, the IN3920 Series. Improving upon the company’s previous interactive features, these installable or portable projectors have an ultra short throw lens, can use two LiteBoard wands at once, and are promoted as an easy-to-use alternative to interactive whiteboards. The IN3924 and IN3926 interactive projectors allow teachers or presenters to turn almost any surface into an interactive workspace — no screen required.

The so-called “magic” is in the wireless LiteBoard wand, which can be used like a mouse to draw, write and click on the projected image. The teacher or presenter can use the wand — held like a pen or remote control — to interact with the image. Two wands can also be used simultaneously, allowing people to interact with the same projected image at the same time.

Both projectors are 1-chip DLP projectors using six-segment color wheels with a specified brightness of 3,000 lumens, offering HDMI, VGA and USB inputs. The IN3924 is XGA (1024×768) and the IN3926 is WXGA (1280×800).

The IN3924 and IN3926 projectors are available now for $1,199 and $1,425, respectively.

Here are all the specs.
