I am an advisor to some students in the MHCI program at CMU. They are in the final 7 weeks of their Masters degree. As part of their Capstone (read 8 month long project) they are working on a physical prototype and are looking for some construction advice.
The basic idea is that they need to project (via rear projection) onto a curved surface. A flexible projection film will be placed onto a curved, rigid surface. The challenge is that there needs to be empty space behind surface (between the back of the film surface and the projector) as to enable proper focus from the projector.
Once constructed, people will interact with the surface by pressing, touching, and moving their hand/fingers along the surface. It needs to be resilient enough to withstand that pressure.
To build this, the initial thought was to have a frame or skeleton supporting the (clear) rigid surface along its edges. The surface itself will likely be acrylic and will need to stand on its own.
Does anyone have experience with a similar project such that you could offer some guidance on construction methods or otherwise?
I can connect you with the students directly if so.
