This toolkit is predicated on the fact that modern PCs and displays (ei- ther CRT-based or flat screen) have sufficient computing power, resolution, and stability to function as reliable measurement tools. A major advantage of PC use for vision testing is that measurement software can be equipped with a high level of fault tolerance. Automated test routines including criterion-free and forced-choice procedures, catch trials, Bayesian threshold approximation, and other sophisticated psychophysical techniques can greatly allevi- ate the need for highly-trained technicians, and the operator's main task can be to make sure that the test sub- ject is cooperative. This fault tolerance does not automatically extend to the setup and calibration of hardware, however. Screen intensity and chromaticity, test distance, room illumination, and a number of other variables can have a significant effect on test thresholds, even when testing the same subject on the same PC under similar conditions. We propose to develop a set of simple hardware tools and control software that will allow necessary hard- ware calibrations and setup to be performed quickly, reliably, reproducibly, and with a very modest level of training on the part of the operator. Under this phase I application we designed a prototype toolkit with hard- ware based on off-the-shelf components and software with a relatively primitive user interface. Under the sub- sequent phase II application we will develop a fully integrated hardware prototype, a fault-tolerant software package with a user-friendly interface, and a detailed product development and commercialization plan.
