METHODS AND SYSTEMS FOR CALIBRATING STIMULUS-RESPONSE TESTING SYSTEMS
First Claim
1. A method for calibrating a stimulus-response test system comprising a stimulus output device for delivering stimulus to a subject and a response input device for receiving a response from the subject, the method comprising:
- sensing the stimulus output by the stimulus output device;
recording a calibrator stimulus time associated with detection of a stimulus event;
generating a calibrator response after detection of the stimulus event;
recording a calibrator response time associated with generation of the calibrator response; and
determining a latency value tlat associated with the stimulus-response test system based at least in part on a calibrator time difference tstim/resp, the calibrator time difference tstim/resp comprising a difference between the calibrator response time and the calibrator stimulus time.

Abstract
Methods are provided for calibrating stimulus-response test systems which include a stimulus output device for delivering a stimulus to a subject; and a response input device for receiving a response from the subject. One such method comprises: sensing the stimulus event output by the stimulus output device; recording a calibrator stimulus time associated with detection of the stimulus event in a calibrator separate from the stimulus-response test system; generating a calibrator response after sensing the stimulus event, the calibrator response causing a response input port of the stimulus-response test system to receive a calibrator response signal and to deliver a corresponding calibrator response signal to the test controller; recording a calibrator response time associated with generation of the calibrator response in the calibrator; and determining a latency value associated with the stimulus-response test system based at least in part on a difference between the calibrator response time and the calibrator stimulus time.
