Abstract: A universal headset-mounted Neuropsychological Testing System utilizes eye tracking, with a single screen fixed with respect to the face and a dot on the screen driven to present an object that both eyes are focused on using a set of prisms, with the prisms eliminating interocular distance considerations. Ultrathin optics cast a virtual image at 40 centimeters and a universal mask against which the test taker's face is placed fixes the single screen with respect to the face so that head movement is not a factor. Additionally, miniature cameras are located in the headset housing beneath the eyes, and a quick release tensioning unit provides easy headset mounting and removal. Moreover, all elements are located in the headset hood to eliminate the effects of head movement as well as environmental distractions.

Abstract: A method is provided for improving cognitive performance assessment in a smooth pursuit cognitive performance test by using measurement metrics including a lead/lag metric, a radial inbounding metric, a path dependent velocity metric, a path drift metric, a velocity variability metric, or a variance statistics metric.

Abstract: The invention describes the process of applying smooth pursuit eye movement tests toward the detection of the efficacy and, or, toxicity of neuro-pharmaceutical compounds throughout the clinical drug development process. Several different paradigms in smooth pursuit tracking tests and several analysis methods and metrics may be used. Application of smooth pursuit tracking tests allows for a quantifiable measurement of a subject's cognitive behavior and function. This process provides a cost effective and objective test of efficacy of neuro-pharmaceutical drugs and increase the validity of the clinical drug development process.

Abstract: A highly portable desktop arrangement for cognitive testing which eliminates environmental effects is provided by a clam shell enclosure having a face mask on one face and housing a computer screen at an opposing wall, with accurate gaze direction measurement made by determining the position of the pupil if an individual whose face is pressed to the mask for eliminating head movement relative to the computer screen.

Abstract: Gesture sensing is used as an input to perform cognitive function testing.

Abstract: A system for monitoring drug taking compliance utilizes cognitive testing after the scheduled administration of the medicine to determine compliance by measuring cognitive function.

Abstract: A system for removing the learning effects from cognitive tests includes variation of the difficulty of the test between the administering of the tests so as to minimize the ability of a test taker to memorize a test.

Abstract: Multimodal cognitive performance testing identifies a benchmark test administered at the beginning and the end of a battery of tests in which cognitive resource changes are detected and are used to correct additional tests sandwiched between the benchmark tests. A test sequence methodology is described for deriving a minimum number of the additional tests and for ordering the additional tests based on multimodal test variables and correlation of a test with a predetermined cognitive function.

Abstract: A method to determine the subject's peak cognitive performance using smooth pursuit tracking tests. The method utilizes instantaneous performance feedback to accurately quantify the subject's peak cognitive performance by changing the difficulty of the test in response to the subject's performance.
