Development of Image Psychophysics Software and Calibrator for Macintosh Systems

Abstract

The core function of noninvasive psychophysical testing is the measurement of contrast sensitivity for spatial patterns specified with some mathematical luminance profile and a controlled time course. Desk-top computers would appear to be ideally suited for such a task and yet most of the software for such computers requires special-purpose hardware modifications and software that requires programming to achieve the desired experimental configuration. In particular, there seems to be no convenient software that take advantage of the graphics sophistication of the Macintosh computer.
