Our SGI Onyx2 computer

Visual

The EVE visual system includes the projectors, the floor and the frame supporting the canvases.

Aural

The multichannel audio system in the EVE is implemented using a dedicated Linux-based PC and special software that is used for acoustic modeling, sound source panning, and equalization filtering. More details.

Interaction

We had acquired an Ascension MotionStar tracker previously, and this was installed into the EVE as the main tracker. Several tests were run in order to determine the least noisy sampling frequencies.

EVE detailed description

Accurate description of implementation is included in licentiate thesis of Janne Jalkanen, titled "Building a spatially immersive display - EVE" (out of date in respect of the current system).
