Learning tool of the future

MANILA, Philippines--In the near future, when this projector technology becomes cheap, teachers will be using pens with virtual ink to write on any wall—in lieu of the lowly blackboard and chalk—to teach lessons in hi-tech classrooms.

Epson, a top projector maker, recently introduced the EB-450Wi, an intelligent and interactive ultra short throw projector (mounted on the ceiling) that allows teachers or people who do presentations to conveniently turn a white board, a wall, or practically any smooth surface into an interactive presentation area.

The technology isn’t new as projector combined with an interactive white board is already in use.
But the EB-450Wi went beyond this technology by featuring the ability to project onto any wall or surface, and the use of a digital infrared pen allows a presenter to manipulate interactive objects and features onscreen—similar to using a mouse to move and point objects on the PC screen.

In addition, the EB-450Wi, which can be mounted on the ceiling of a classroom, features a short throw technology that already eliminates glare and shadows from the projected light, resulting in seamless presentations with sharper colors and images.

“We believe that the Epson EB-450Wi ultra short throw interactive projector is the ultimate learning tool of the future,” said Epson senior general manager Ed Bonoan.

Apart from the revolutionary EB-450Wi, Epson also introduced its latest projectors equipped with the dynamic 3LCD technology—a new projector technology that offers dedicated color projection by using three separate LCD panels for red, green and blue (RGB) projections.

This ensures smooth projection of image without color breakup (or rainbow effect), distorted image patterns and visual fatigue.

Intended for large venue screenings, the EB-Z8050W is Epson’s brightest projector boasting of a rating of 7,000 lumens.
The EH-TW4500 home theater, on the other hand, features the highest contrast ratio of 200,000:1 (highest in the world for a projector) and capability of doing full HD 1080p, a feature that can already make a living room like a real cinema room when viewing movies using this projector.

For business use, the low power consuming EB-8 series features cable-free projections, network control, and the ability to project JPG image files stored in flash drives or PCs via USB ports.

Suggested retail price for the classroom interactive projector EB-450Wi is P106,900, while the EH-TW4500 home theater projector carries an SRP P156,000.
