TED Talk – JoAnn Kuchera-Morin: Tour the AlloSphere, a stunning new way to see scientific data
The AlloSphere uses two 5 metre radius half spheres made from optically opaque and acoustically transparent perforated aluminium. They are housed in a three story anechoic chamber. The viewers stand on a bridge that positions their heads near the centre of the sphere. The images are projected onto the inside of the hemispheres from a projector positioned in the seam between them.
The examples in the video seem to be fairly low resolution, at this stage there are only two projectors in operation (one for each hemisphere). They are installing multiple high resolution projectors around the seam between the two spheres to be able to do ‘eye limited’ resolution in 3D. The audio uses multiple speakers to achieve 3D audio.
