    • A multimedia presentation system a projector to project images toward an audience. A plurality of nozzles are partially submerged in a body of water at locations between the projector and the audience. The plurality of nozzles are located at different distances from the projector. Each of the plurality of nozzles is arranged to produce a fan like water mist onto which the projector projects images. A controller is coupled to the projector and the plurality of nozzles. The controller causes the projector to project images and at least one of the plurality of nozzles to produce a water mist in a synchronized sequence such that the images appear at different distances from the projector at different times. The controller may further control the orientation of each nozzle to vary the distance by inclining the plane of the water mist relative to the surface of the body of water.
    • 一种多媒体演示系统,用于向观众投影图像的投影仪。 在投影机和观众之间的位置处,多个喷嘴部分地浸没在水体中。 多个喷嘴位于与投影仪不同的距离处。 多个喷嘴中的每一个布置成产生投影仪投影图像的风扇,如水雾。 控制器耦合到投影仪和多个喷嘴。 控制器使得投影仪投影图像和多个喷嘴中的至少一个以产生同步顺序的水雾,使得图像在不同时间出现在与投影仪不同的距离处。 控制器可以通过使水雾的平面相对于水体的表面倾斜来进一步控制每个喷嘴的取向以改变距离。
