ViSaGe AGP Upgrade (requires return of existing ViSaGe unit)
Planned Upgrade Path for 64-bit Windows Compatibility
If you have an original ViSaGe unit (serial numbers starting 7.1), you can upgrade to a ViSaGe MKII to get compatibility with 64-bit Windows with the new VSG Software Library v8.3 release.
In addition to the usual VSG mode of operation, all ViSaGe MKII systems can also be operated in Bits# mode, making them compatible with community tools like Psychtoolbox, PsychoPy, and Psykinematix on any platform.
How Does The Upgrade Work?
Just return your original ViSaGe unit to our factory in the UK, and we send you back a new MKII unit in exchange.
Important – check which graphics card you have!
If your ViSaGe is connected to a Wildcat VP880 or Wildcat VP990 AGP card (which is installed inside your PC), then you need to upgrade both the graphics card and your ViSaGe unit, at the price showed above.
If it’s already connected to a Wildcat R500 PCI Express card, you can keep the R500 card and get an even better deal.
ViSaGe makes it simple to display calibrated visual stimuli on a CRT-based computer monitor with precision timing, and provides a robust and reliable mechanism to synchronise the stimulus presentation with external data collection equipment, including button boxes or eye trackers, motion trackers, electrophysiological amplifiers, and MRI scanners. It is the ideal choice for cognitive, psychophysical, and neurophysiological investigations of vision and the brain.
Why do I need 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 always that simple. Most systems are really designed for games: they are difficult for novices to program and unsupported by the manufacturer. Often their dynamic range is limited, with inadequate contrast and colour control for experimental applications, and timing is unpredictable.
You need the ViSaGe advantage:
Real-time driver for Windows guarantees frame-synchronous presentations even at 100Hz+ frame rates
14bit colour and luminance control with integrated support for gamma correction and colour calibration
Dedicated PCI Express framestore to buffer sequences of precalculated images
Integrated digital I/O interface
