Abstract

A system and process for calibrating the presentation of stimuli and/or hit window by ascertaining the hit window relative to stimuli presented on a computer. The system includes a first circuit for generating the stimuli, and a second circuit for simulating responses to the stimuli. The response initially does not overlap the hit window and causes an incorrect response cue to be generated. Either the start time of the response or the duration of the response may then iteratively be modified to cause the response to eventually overlap the hit window, thereby generating a correct response cue. The two consecutive responses that cause the hit window to be nonoverlapped and then overlapped are identified for the purpose of ascertaining the range of time that includes the start of the hit window. Either the start time of the response or the duration of the response may be iteratively varied to cause the hit window to be nonoverlapped by the response, thereby causing the incorrect response cue to be generated. The two consecutive responses that cause the hit window to be overlapped and then nonoverlapped are identified for the purpose of ascertaining the range of time that includes the end of the hit window. The timing data pertaining to the hit window may then be employed to adjust the presentation of the stimuli and/or the hit window to conform to the desired presentation timing.

Claims

1. A computer-implemented apparatus for ascertaining a hit window relative to stimuli, comprising:

means for generating said stimuli,

means for simulating responses to said stimuli, said responses being variable in time so that at least one of said responses overlaps said hit window and another one of said responses does not overlap said window;

means for analyzing said responses to ascertain a start time of said hit window and an ending time for said hit window.

2. A system for standardizing presentation of a hit window relative to presentation of user stimuli for an input device used in conjunction with a computer system to ensure that a beginning and a duration of a range of response time is substantially consistent across different administering computers, said system comprising:

a first circuit capable of generating a stimulus, wherein the first circuit includes a processor configured to ascertain a start time of said hit window and an ending time of said hit window;

a second circuit capable of simulating responses to the stimulus;

a data acquisition interface electrically connected to the first circuit and electrically connected to the second circuit; and

an input device electrically connected to the data acquisition interface.

3. The system of claim 2 further including an output port electrically connected to the first circuit.

4. The system of claim 2 wherein the second circuit includes a relay chip electrically connected to the data acquisition interface.

5. The system of claim 4 further including data instructions to drive the relay chip.

6. The system of claim 2 wherein the second circuit includes a signal line driver electrically connected to the data acquisition interface.

7. The system of claim 6 further including data instructions to drive the signal line driver.

8. The system of claim 2 wherein the stimuli is an auditory stimuli.

9. The system of claim 2 wherein the input device is a mouse.

10. The system of claim 2 wherein the stimulus is included in a training program.

11. The system of claim 10 wherein the training program is designed to build language skills in children.

12. The system of claim 2 further including at least one transducer for delivering the stimulus.

13. The system of claim 2 wherein the at least one transducer includes a sound generator.

14. The system of claim 2 wherein the second circuit includes a data acquisition processor.
