Seiko Epson Corp will release a projector that can be operated by touching a projected screen with a finger for use in schools May 29, 2014, in Japan.
The company has been selling projectors that can be operated by touching a projected screen with an electronic pen since 2010. And this is the first time that it has supported touch operations with a finger.
The touch sensor unit of the new projector, "EB-595WT," emits infrared light so that it covers the projected screen. When a finger touches the infrared light, a camera embedded in the main unit will detect it. As a result, it becomes possible to intuitively operate the "tool buttons" of an electronic white board and scale and scroll the screen by moving a finger on the projected screen.
To draw characters and complicated figures, an electronic pen that comes with the projector needs to be used. But it is possible to draw simple figures such as an arrow, triangle, circle, etc with a finger. In addition, like a normal white board, operations such as "writing with a pen and erasing with a finger" are possible. Two persons can write in or operate mouses at the same time.
