Is ViSaGe suitable for my experiment; what stimuli can I present?
ViSaGe can display any visual stimulus that can be defined by a mathematical function and saved as a maxtrix or array of RGB values. It can also display bitmap images that you might obtain from other sources like digital cameras and scanners, or created using Photoshop-type software packages. If you want to display a stimulus that changes over time, stimuli created by ViSaGe can be spatially and temporally modulated in a number of ways, but often through using look-up tables (LUTs) or sequences of precalculated frames. The special hardware and software features make this simple to achieve, and often in ways that are conceptually trivial compared to the complexities of other low-level graphics approaches.
