Sony has launched three new additions to its ultra short throw projector family, the VPL-SW535C, VPL-SW525C and VPLSW525.

The company added interactive writing capabilities for the VPL-SW535C and VPL-SW525C, which enable simultaneous dual-touch interactive annotation on the projection screen with the use of supplied pen devices and drawing software. The interactive pens work as a computer mouse or writing device during virtual whiteboard mode. In a classroom environment, they allow users to easily incorporate many of third party curriculum software products to launch interactive lessons. In a corporate environment, instant communication space can be established using virtual whiteboard mode.

The new models are capable of delivering a large image from an extremely short distance (e.g., an 80-inch image can be achieved from 19 inches distance from the screen). All the three models offer WXGA projection with the VPL-SW535C claiming 3000 lumens color light output and VPL-SW525C and VPL-SW525 spec’ing 2500 lumens. Features include auto lamp dimming, a 6,000-hour expected lamp replacement timing, four percent vertical and two percent horizontal optical lens shift and a supplied wall mount bracket.

Here are all the specs:
