The CoreVision library is a multi-platform framework for performing psychophysical experiments.

CoreVision brings together the features of several leading vision research software packages, wrapping them into a small, object-oriented software library with a well defined API. CoreVision is compatible with Mac OSX, Windows XP, and POSIX-compliant Unix systems and is distributed as a static or dynamic C++ library. CoreVision also provides APIs for C, Matlab, Objective-C and Python.

Expo is a program for generating visual displays and analyzing responses, either physiological or psychophysical, in real time. Most of its capabilities have been provided to control spatio-temporal patterns on television displays (it uses standard OpenGL video functions to produce these) but it can control other devices, and is extensible. Most of its data-handling capabilities are organized for the analysis of spike trains recorded from one or several cells, but it can record analog signals continuously and can run psychophysical threshold-finding procedures such as Quest, and is extensible also in this domain.
