Funai and Nippon Signal have developed the Eco Scan mini projector that is able to produce touch sensitive images. The projector utilizes Nippon Signal’s MEMS scanner and RGB laser light is scanned by a two-axis MEMS mirror to project a color image.
The Eco Scan projector is able to determine the position of a finger. To realize this function, a sensor that recognizes the intensity of light is placed near the projection screen. When a projected image is touched by a finger, part of the laser light is cut off. Then, the sensor detects a change in light intensity.
The Eco Scan is still a prototype and Funai may commercialize it as early as within 2010.
