Abstract

Methods and apparatus that provide proper identification of visual and neurological abilities related to defects in the neurological component of the brain, that improve visual and neurological performance, and that develop improved neural performance in the brain and nervous system. All of these methods are carried out over a communications network such as the Internet.

Claims

1. A system for improving the visual perception ability of a user, comprising:

a client terminal including a display device, an input device, and a client processor;

and a host server including a host storage device, and a host processor communicatively coupled to said client processor;

said host storage device having stored therein a first plurality of parameters of images selectable to test the visual perception ability of the person with respect to at least one visual defect and to elicit responses from the person indicative of the presence or absence of said at least one visual defect, and a second plurality of parameters of images designed to treat the person with respect to a detected visual defect and thereby to improve the visual perception ability of the person with respect to such detected visual defect;

said display device being controlled by said client processor and host processor for displaying to the person, selected images of said first plurality of parameters and of said second plurality of parameters;

said client processor and host processor being controlled by said client input device;

(a) to receive said first plurality of parameters, to generate a first plurality of images corresponding thereto, and to display said first plurality of images in said display device;

(b) to register responses inputted by the user via said input device;

(c) to utilize said user responses to select the parameters of said second plurality of images in said host storage device corresponding to the images designed to treat the person with respect to a visual defect detected from said responses; and

(d) to control said display device to display to the user, in a treatment phase, the selected images in said second plurality in at least one treatment session until the visual perception ability of the person has been improved with respect to said detected visual defect.

2. The system of claim 1, wherein the client terminal and the host server arc communicatively coupled via a communications network.

3. The system of claim 2, wherein the communications network comprises the Internet.

4. The system of claim 1, wherein the client terminal further comprises:

a client storage device comprising a computer-readable medium communicatively coupled to the client processor;

a persistent memory communicatively coupled to the client processor,

and a communication interface communicatively coupled to the client processor, said interface being configured to transmit data to and from the host server via the communications network.

5. The system of claim 4, wherein one or more sequences of client processor executable instructions are stored in the client storage device which cause the client processor to perform a number of acts, comprising:

generating an image;

receiving an input from a user based on the user'"'"'s perception of the image; and

generating a further image based on the input.

6. The system of claim 5, wherein the act of generating a further image is carried out by modifying one or more parameters of the image.

7. The system of claim 5, wherein the act of generating a further image is carried out by selecting a new image from a predefined set of images.

8. The system of claim 5, wherein the act of generating a further image is carried out using a configuration that is more difficult to perceive if the user does accurately perceive a characteristic of the image.

9. The system of claim 5, wherein the act of generating a further image is carried out using a configuration that is less difficult to perceive if the user does not accurately perceive a characteristic of the image.

10. The system of claim 5, wherein the acts to be performed by the client processor further comprise generating a series of images used to ascertain the visual and neurological perception ability of the user.

11. The system of claim 5, wherein the image generated comprises one or more Gabor patches.

12. The system of claim 1, wherein the host server further comprises:

a persistent memory communicatively coupled to the host processor, and

a communication interface communicatively coupled to the host processor, said interface being configured to transmit data to and from the client terminal via the communications network.

13. The system of claim 12, wherein the host server further comprises:

a user database communicatively coupled to the processor for storing user information.

14. The system of claim 12, wherein one or more sequences of host processor executable instructions are stored in the host storage device which cause the host processor to perform a number of acts, comprising:

selecting parameters and delivering them to the client terminal;

receiving a set of user inputs from the client terminal;

analyzing the set of user inputs; and

generating one or more farther parameters to deliver to the client terminal based at least in part upon the analysis performed on the set of user inputs.

15. The system of claim 14, wherein the acts performed by the one or more sequences of host processor executable instructions further comprise authenticating a user.

16. A method of improving the visual perception ability of a person, comprising:

in a client terminal, displaying to the person, in at least one evaluation session of an evaluation phase, a plurality of images selected to test the visual perception ability of the person with respect to at least one visual defect, and to elicit responses from the person indicative of the level of the person'"'"'s visual perception ability with respect to said at least one visual defect;

communicating the responses of the person to a remotely-located host server;

utilizing said responses to select in the host server another plurality of images designed to treat the person with respect to a detected visual defect and thereby to improve the visual perception ability of the person with respect to the detected visual defect;

and in the client terminal, displaying to the person, in a treatment phase, said another plurality of images in at least one treatment session until the visual perception ability of the person has been improved with respect to said detected visual defect.

17. The method according to claim 16, wherein said treatment phase includes a plurality of treatment sessions in each of which are displayed to the person a plurality of images designed to elicit responses to be used for selecting the plurality of images in the subsequent treatment session such as to progressively improve the visual perception ability of the person with respect to such detected visual defect.

18. The method according to claim 17, wherein at least one predetermined parameter of the plurality of images displayed in one treatment session is varied in the subsequent treatment session.

19. The method according to claim 17, wherein each of said treatment sessions includes a plurality of visual perception tasks in each of which there is displayed to the person at least one image designed to elicit a response useful for selecting at least one other image to be displayed in the subsequent visual perception task of the respective treatment session such as to progressively improve the visual perception ability of the person with respect to the detected defect.

20. The method according to claim 16, wherein said evaluation phase includes a plurality of evaluation sessions in each of which at least one plurality of images are displayed to the person to elicit responses, the responses of each evaluation session being utilized to select the plurality of images to be displayed in the next evaluation session.

21. The method according to claim 20, wherein each of said evaluation sessions includes a plurality of visual perception tasks in each of which there is displayed to the person at least one image designed to elicit a response useful for selecting at least one other image to be displayed in the subsequent visual perception task of the respective evaluation session such as to progressively improve the evaluation of the visual perception ability of the person with respect to the detected defect.

22. The method according to claim 16, wherein said plurality of images in at least the treatment phase are images based on Gabor Functions.
