Abstract

System and methods for testing and/or training a subject'"'"'s visual perception span and/or speed are provided. More specifically, a method may include testing/training various aspects of the subject'"'"'s visual perception span/speed through the use of assessments that test the subject'"'"'s ability to receive and retain information that is flashed in front of them. By using various assessments, an efficient examination may be administered. In accordance with the invention, an individual may be subjected to such a method of testing/training comprising: presenting one or more two-dimensional representations to the subject at a first time; receiving input responses from the subject at a second time; and processing the received input responses to provide a measure of the perception span of the subject; and processing the time between the first time and the second time to provide a measure of the perception speed of the subject.

Claims

1. A system for measuring the visual perception span and/or speed of a subject, comprising:

a display device capable of displaying a two-dimensional representation, the display device comprising a plurality of portions in a two-dimensional arrangement, each portion capable of activation independence;

an input device capable of receiving a plurality of responsive inputs from the subject, each of the plurality of responsive inputs corresponding to a portion on the display device; and

a test unit operably connected to the display device and the input device, the test unit operable to;

cause the display device to display a first two-dimensional representation for a first predetermined amount of time, the first two-dimensional representation comprising a first plurality of active portions of the display device;

cause the display device to cease to display the first two-dimensional representation after the conclusion of the first predetermined amount of time;

cause the input device to receive, for a second period of time, any of a plurality of inputs from the subject, each of the plurality of inputs corresponding to at least one portion of the display device;

after the second period of time, compare the plurality of inputs received by the input device during the second period of time to the first two-dimensional representation displayed by the display device during the first period of time to determine;

which of the plurality of inputs correspond to an active portion of the first two-dimensional representation;

which of the plurality of inputs do not correspond to an active portion of the first two-dimensional representation;

which of the active portions of the first two-dimensional representation a corresponding input; and

outputting the results of the comparison.

2. The system of claim 1, wherein the first plurality of active portions is fewer in number than the plurality portions capable of activation.

3. The system of claim 1, wherein the display device comprises one or more display screens.

4. The system of claim 1, wherein the display device comprises eyewear.

5. The system of claim 1, wherein the plurality of portions comprise more than one color.

6. The system of claim 1, wherein the input device is operable to receive any of a plurality of inputs from the subject immediately after the conclusion of the first period of time.

7. The system of claim 1, wherein the first period of time and the second period of time may overlap.

8. The system of claim 1, wherein the plurality of active portions comprises at least one characteristic distinct from the plurality of inactive portions.

9. The system of claim 1, a second two-dimensional representation is presented for a third period of time, wherein the third period of time is capable of overlapping at least one of the first and second periods of time.

10. The system of claim 1, wherein the display device and the input device comprise a single touch-sensitive screen.

11. A method for measuring the visual perception span and/or speed of a subject, the method comprising:

orienting the subject within view of a display device and within reach of an input device, wherein

the display device comprises a plurality of display portions in a two-dimensional arrangement, each of the plurality of display portions being capable of activation independent of the other display portions; and

the input device comprises a plurality of input portions in a two-dimensional arrangement corresponding to the two-dimensional arrangement of the plurality of display portion, each of the plurality of input portions capable of registering an input independent of the other input portions;

causing the display device to activate a subset of the plurality of display portions to render a two-dimensional representation viewable to the subject, the activation of the subset of the plurality of display portions lasting for a first period of time;

registering any inputs provided by the subject at a subset of the plurality of input portions of the input device during a second period of time; and

determining the amount of correspondence between the subset of display portions activated during the first period of time and the subset of the plurality of input portions registering inputs during the second period of time.

12. The method of claim 11, wherein the display device and the input device comprise the same touch-sensitive screen.

13. The method of claim 11, wherein the any inputs provided by the subject at a subset of the plurality of input portions of the input device are registered after the first period of time has been completed.

14. The system of claim 11, wherein the amount of correspondence between the subset of display portions activated during the first period of time are determined after the completion of the second period of time.

15. The system of claim 11, wherein subset of the plurality of input portions registering inputs during the second period of time are determined after the completion of the second period of time.

16. A system for testing or training the visual perception span and/or speed of a subject, the system comprising:

a display device having a plurality of display portions arranged in a two-dimensional lattice, each of the portions capable of independent activation;

a touch-sensitive input device having a plurality of input portions arranged in a two-dimensional lattice corresponding to the plurality of display portions on a one-to-one spatial basis, each of the input portions capable of independent receipt of an input;

a testing unit operably connected to the display device and to the touch-sensitive input device, the testing unit operable to;

cause the display device to activate, for a first period of time, a subset of the display portions to display a first amount of visual information in a two-dimensional figure comprised of activated display portions to the subject;

cause the display device to cease to present the two-dimensional figure to the subject;

cause the input device to receive for a second period of time any inputs from the subject provided to any of the plurality of input portions;

compare any inputs received at any of the plurality of input portions during the second period of time to the subset of display portions activated during the first period of time to determine the degree of correspondence between any input received and the activated display portions.

17. The system of claim 16, wherein the display device and the input device comprise the same touch-sensitive screen.

18. The system of claim 16, wherein the display device is caused to cease to present the two-dimensional figure to the subject at the conclusion of a first period of time.

19. The system of claim 16, wherein the input device is caused to receive any inputs from the subject provided to any of the plurality of input portions after the completion of a first period of time.

20. The system of claim 16, wherein any inputs received at any of the plurality of input portions during the second period of time to the subset of display portions activated during the first period of time to determine the degree of correspondence between any input received and the activated portions are compared after the completion of a second period of time.

21. The system of claim 16, wherein the first amount of information displayed may be varied by the testing unit.

22. The system of claim 16, wherein the first period of time may be varied by the testing unit.
