Abstract: Graphical first individual interfaces, systems and methods of implementing an adaptable, interactive educational tool that provides cognitive and social benefits. An embodiment can be configured to provide a graphical first individual interface for presenting text and related content associated with a predetermined general subject matter. The specific text and related content presented to the first individual may be determined after baseline tests and related use are recorded to calculate the first individual's cognitive wellness. The present invention also provides social benefit by integrating a first individual's social network for uses in communication with the first individual's social network and in recalling the first individual's social network. The present invention further includes a unique algorithm for personalizing information and methodologies of implementing and displaying the educational tool to a first individual thereof.

Abstract: The invention relates to a method for characterizing a perception of blur by a subject (10) in order to determine a dioptric blur value for an image (C) observed by the subject. The image has a blur generated by the low-pass filtering of the image components in accordance with the respective space frequencies of said image components. An indication of the perception thereof of blur in the image is provided by the subject and is associated with the dioptric blur value. Several images associated with different dioptric blur values are used for defining a dioptric blur threshold value for the subject that corresponds to a blur perception criterion. The invention can be used for adjusting the design of a progressive lens for the subject in accordance with the sensitivity to said visual blur of said object.

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.

Abstract: Computer-implemented method for enhancing a participant's cognition, including, e.g., visual memory, utilizing a computing device to present visual stimuli for training, and to record responses from the participant. Multiple graphical elements are provided for visual presentation to the participant. A temporal sequence of a plurality of the graphical elements is visually presented, including displaying each graphical element in the sequence at a respective location in a visual field for a specified duration, then ceasing to display the graphical element. The presented graphical elements include at least two matching graphical elements. The participant is required to respond to the presented sequence, including indicating locations of matching graphical elements. A determination is made as to whether the participant responded correctly, and the duration modified based on the determining.

Abstract: A computerized method for recording and scoring the process by which an examinee performs cognitive or psychological grapho-motor tasks that call for the use of pencil and paper, such as drawing or copying graphical configurations or text. The examinee uses a digital pen that leaves a trace on a writing pad. The trace is digitized in real time, input to a computer and stored in memory as a time dependent image. The image may be displayed and scored in real time or at a later stage on a computer display. The examiner can easily replay and reevaluate the graph-motor task process at a later stage.

Abstract: A contrast chart device of the present invention comprises a contrast target presenting part for presenting a contrast target for a contrast sensitivity test at prescribed timing; a pupil data measuring part for producing an image of an anterior ocular segment of a subject and measuring the diameter or area of a pupil region in the anterior ocular segment; and a measurement timing forming part for forming timing at which the pupil data measuring part performs measurement.

Abstract: The motion contrast visual sensitivity of an individual is tested by means of a target having thereon patches each composed of alternating light and dark bars, with individual patches varying in contrast and spatial frequency, and also in orientation. The target is viewed by way of a slot through a housing positioned in front of the individual under test, and a shutter rotating within the housing at a controlled speed periodically blocks the slot at a rate sufficiently slow, e.g. 30 cycles per second, for the observer to detect the resulting conditions of flicker.

Abstract: A tachistoscope system is presented in which separate images may be sent to the left and right hemispheres of the visual cortex. A subject-worn viewing system having electro-optical valves is used to cover the right and left visual fields of the subject and the valves are operable in response to control signals. These control signals also synchronize the inputs from 2 television cameras with the opening of the valves. An alternative embodiment employs lenses of different colors arranged to cover the right and left visual fields of the subject and means for displaying colored areas of output.
