Adaptive visual performance testing system

An adaptive visual performance testing system, comprising:

• a memory storing a plurality of visual recognition tests and outcome probability associated with each visual recognition test;
• a display operable to display an image for each of the visual recognition tests to a subject;
• an input device operable to receive a response to each of the visual recognition tests from the subject;
• and
• a processor operable to execute instructions stored in the memory to perform the following steps:
• (a) displaying one of the visual recognition tests to a subject;
• (b) receiving from the subject a response to the visual recognition test;
• (c) after receiving the response to the visual recognition test, selecting a subsequent visual recognition test having selected outcome probability information determined based on the response from the subject;
• (d) displaying the subsequent visual recognition test;
• (e) receiving from the subject a response to the subsequent visual recognition test;
• (f) repeating steps (c)-(e) until a stopping criterion is achieved;
• and
• (g) outputting a visual performance score determined based on the set of responses received from the subject and the outcome probability information for the visual recognition tests displayed to the subject.

Software, embodied in a computer-readable medium operable, when executed by a processor, to cause the following steps to be performed:

• (a) providing a memory storing a plurality of visual recognition tests and outcome probability information associated with the visual recognition test;
• (b) displaying one of the visual recognition tests to a subject;
• (c) receiving from the subject a response to the visual recognition test;
• (d) after receiving the response to the visual recognition test, selecting a subsequent visual recognition test having selected outcome probability information determined based on the response from the subject;
• (e) displaying the subsequent visual recognition test;
• (f) receiving from the subject a response to the subsequent visual recognition test;
• (g) repeating steps (d)-(f) until a stopping criterion is achieved;
• and
• (h) outputting a visual performance score determined based on the set of responses received from the subject and the outcome probability information for the visual recognition tests displayed to the subject.
