Worlds First Multi Finger Touch Interactive Projector - Epson 595Wi

Touch Interactive Projector

It has taken a while - but Epson has finally invented a pen-less interactive projector.

For about 5 years we have been selling the Epson range of ultra short throw interactive projectors. Starting with the EB 450Wi in 2010, then the EB 455Wi, then the massively popular EB 485Wi from 2012 until May this year. The final incarnation of this projector is the EB 585Wi - and we still sell these more than just about any other projector.



The ultra short throw form factor is perfect for interactive projection, with a reduced shadow, higher brightness and more accurate calibration.

The defining feature with these projectors was that the interactivity was smooth and responsive without the use of a special board, any whiteboard could be used as a projection and interactive surface. But there was one thing that customers asked for - finger touch capability. These projector rely on a stylus system, special pens that had to be used to interact with the computer and give the position of the cursor.

A couple of months ago Epson released the EB 595Wi - a finger touch based interactive projector. Looking exactly the same as the 585Wi pen based unit - the 595Wi also comes with a separate IR curtain module that projects a curtain of IR across the surface of the board  - and when a finger or any other object breaks or frustrates the curtain it lights up in infra-red and the camera in the projector picks up the XY position on the board and translates that break as a touch. It is a variation on the Frustrated IR touch screen system.

We have now put it in a few schools and colleges and the feedback we have had so far has been great - teachers find it more natural to touch without a pen - especially with Windows 8 and the gestures you can use normally with a tablet.

The one drawback is that the IR curtain projector must be placed above the projection, but on the same surface as the projected image - taking up about 15cm of space at the top of the board. This reduces the image size that can be projected on a standard 1200mm high whiteboard by about 5"-7" diagonally.. Yes I know I'm mixing up my measurements but diagonals seem to be standardised in inches.

Some of our clients are getting around this by buying non standard 1400mm high whiteboards to get back the full size of the the projection. others are just happy with a slightly smaller projection. Epson are apparently developing an off board solution as well.

These projectors are now on special - at less that $AU 2000 ex GST.
