Hello everyone To start I would like to introduce myself. My name is John-Nicholas Furst, I am an engineering student at Boston University. I wanted to get some feedback on my project idea before submitting the official proposal later.
Note this is just a first draft of the project, I will be adding the more nitty gritty deals to the proposal at a latter date (probably tomorrow) I am just so excited and interested in feedback that I wanted get something down in the forums to get started.
The first part of this project is to replicate a setup somewhat similar to a Microsoft Secondlight.
If you are not familiar with this research project, I will quickly describe it here. Think of a Microsoft Surface, now add the feature of the table being able to project images onto opaque objects held above it. Now this is hard to picture until you see it, but basically this allows for layers of information.
There is the display on the surface of the table, and this invisible secondary display above the surface that only becomes visible when there is something there to diffuse the light enough to capture the image instead of letting it just go up into the air.
Now if that was not already enough of a challenge hardware and software wise, I want to up the ante and make the entire thing 3D.
So this basically would involve having a second set of projectors calibrated on the surface, and having all of the projectors have the proper polarizing filters to make it pump out beautiful 3D.
So that is the very simplified idea. Again I will add the tech specs later but just to give early responders an idea of proposed materials, I am looking at a DSI setup with Endlighten, four projectors (running at 60hz), 2 for the regular surface and above surface projecting, and the other two to make 3D possible on both the surface and above surface displays, a sheet of Polymer Stabilized Cholesteric Textured (PSCT) liquid crystal to control surface transparency (this is basically the material you see in privacy areas or sometimes interrogation rooms, it is diffused under normal situations, but when a current is applied to it, the molecules align themselves and cause the material to become transparent), two webcams for tracking,four shutters(capable of 60 hz) for the projectors, and of course some computing power to bring it all together.
It would also be possible to add in rfid and Bluetooth connections to make it more Surface-esk but that is not really the point, the point is to develop code to deal with 3d multi-touch, deal with multiple layers of multi-touch, and provide documentation as to how to make this elaborate beast.
So what do you think?
