Why do I need a ViSaGe ?

Getting from that brilliant insight to the crucial experiment can be the hardest part of any research project. The choices for visual stimulus generation can be bewildering, but false starts waste your time and money.

Computer graphics seem the obvious solution, but it's not that simple. Most systems are designed for games: they are difficult to program and unsupported. Their dynamic range is limited, with inadequate contrast and colour control, and timing is unpredictable. You need the ViSaGe advantage ...

The ViSaGe Advantage

The ViSaGe is based on graphics hardware from an industry leader. Unlike most graphics systems that are designed for games playing, this chipset is also highly optimised for 2D drawing.

Accurate timing

Our proprietary real-time driver ensures accurate stimulus timing and accesses the hardware independently of Windows. This ensures that displays change exactly when you want them to: dropped and inserted frames are simply not an issue.

Precise luminance and chromaticity

14-bit video DACS and precision calibration devices mean that stimulus luminance and chromaticity characteristics are precisely defined in an enhanced dynamic range. This guarantees the best possible display quality from the stimulus monitor.

New release: Spring 2006

With the advent of computer systems using the new PCI Express bus technology, we have now released a new version of the ViSaGe system using PCI Express technology. The new system provides a new real-time driver to increase the performance of stimulus presentations and to provide access to enhanced graphics capability. The new system replaces the original AGP based ViSaGe.

Comments Tom Robson, CRS Managing Director, “This new ViSaGe system recognizes the demise of AGP based computer systems in the market and their replacement by the new PCI Express PCs and also advances the performance available to our customers in developing new and more advanced experiments to further their science”.
