The camera should be placed directly in front of the projector under the center of the surface so it can pick up the entire desired area.The NUI Group has been working hard to bring the PS3 Eye to windows. Lastly, position the camera so it faces directly upwards towards the acrylic layers.
You also may need to move the projector forwards or backwards, or the acrylic layers up and down in order to achieve the image size you desire. At this point the image will probably look more like a trapezoid, adjust the keystone on the projector until a perfect rectangle is achieved. A front surface mirror is a necessity since an ordinary mirror will distort the image reducing the clarity of the image projected onto acrylic surface. Next setup the front surface mirror so that it reflects the projector onto the acrylic layers above. All that remains to do is to setup the projector and camera and align them so that they cover the same area and are not distorted.įirst place the projector under the surface, with a slight angle of elevation so it is not projecting onto anything directly in-front / below it. The surface at this point is almost complete. This layer is important since it protects the other more expensive layers and is the layer that the actual user will be touching. The abrasion resistant layer should be placed on top of the rear projection layer. This layer will act as a diffuser for the projector, that way the projector does not simply shine directly though the surface at the user.
The rear projection layer should be placed directly on top of the EndLighten layer. You do not need to polish the other two layers, and I actually recommend that they remain rough that way no IR light can shine into them. Notice, the edges will still appear milky at this point, this is normal for EndLighten acrylic. Finally, polish the edges with a plastic polish (Brasso will work too).
Start with 600 grit (lower if the saw cut is rough) and sand each edge until they are perfectly smooth. If a laser cutter is not an option, then automotive sandpaper will do the trick. If it is possible, I recommend laser cutting the EndLighten layer since that will automatically polish the edge to perfection. Therefore it is necessary to polish the edges of this layer in order to maximize the amount of IR light that can be injected into it. This layer is the one responsible for redirecting the IR light from its sides out the top and bottom surfaces of the acrylic. The most important acrylic layer is the EndLighten acrylic.
