A reaction-testing system is provided to simulate motion to an individual. Generally, the reaction-testing system includes a motion-simulating device, a reflective device, a control unit, and an input device that is activated by an individual In exemplary embodiments, the motion-simulating device includes a beam that accommodates a first and second plurality of light sources capable of, at least, alternating between an active and idle condition. These light sources are arranged amongst occlusion features in a mounting pattern such that light emitted from the first plurality is directly viewable by an individual and light emitted from the second plurality is indirectly viewed by the individual through the reflecting surface. The control unit is configured to sequentially activate the light sources sequentially to generate pulses of light on that, when perceived by the individual, appear as a light moving along a vector.

Devices and methods for testing a subject's visual ability are provided. More specifically, the device may include a perspective vision tunnel comprised of plurality of low reflectance walls with one or more mirrors arranged within the perspective vision tunnel. Visual indicia for administering the test of a subject's visual ability are displayed into a first portion of the perspective vision tunnel. The one or more mirrors are arranged to reflect the visual indicia out of the first portion such that visual indicia may be visually perceived by the subject. In accordance with the invention, a subject may be tested utilizing the perspective vision tunnel and input may be received from the individual. The received input may then, for example, be used to compute data related to the user's visual ability.

Conical face shields, sports helmets, and methods for orienting a conical face shield in a sports helmet are described. In embodiments, the conical face shield has at least two opposing arcuate edges, at least two opposing side edges, and a shield. The arcuate edges each have a first end, a second end, and an edge surface extending between the first end and the second end. Further, the edge surface of the first arcuate edge and the edge surface of the second arcuate edge include an arc segment and the arc segment of the edge surface of the first arcuate edge is part of an ellipse with a greater semi-minor axis than the semi-minor axis of the ellipse forming the arc segment of the edge surface of the second arcuate edge. In various other embodiments, the conical face shield may be horizontally and/or vertically tapered.

摘要:
The visual, cognitive, and coordination skills of a subject may be tested and/or trained by providing a variety of stimuli to a subject. Responses may be received from a subject, the appropriateness of which may depend upon the combination of stimuli provided to the subject. A touch screen display device may be used both to provide stimuli and to receive responses from a subject. Any number and type of output devices and input devices to receive responses may be used. Behavioral information and other data regarding the performance of a subject may be recorded. Scoring may be based upon the speed, accuracy, and other aspects of the performance of a subject.
摘要:
The visual and cognitive skills of a subject may be tested and/or trained by providing a visual stimulus to a subject. More particularly, a subject may be tested and/or trained when under a stress condition to determine the effect of a stress condition, such as a physical stress or a cognitive stress, on the subject's visual and sensory skills. A response may be received from a subject via an input device, the appropriateness of which may depend upon the stimulus provided to the subject. Behavioral information and other data regarding the performance of a subject and the possible effect of the stress condition may be recorded. Scoring may be based upon the speed, accuracy, and other aspects of the performance of a subject.

Unified vision testing and/or training kiosk may utilize display devices and input devices to administer a number of visual testing and/or training tasks to an individual. One or more display devices may provide desired resolution, geometry, and/or touch sensitivity. One or more input devices may receive inputs of different types from different positions relative to a display device. Methods of visual testing and/or training may utilize the one or more display devices, one or more input devices, and/or other types of equipment to evaluate and/or improve the visual abilities of an individual.
摘要:
The visual and/or visualization skills of a subject may be tested and/or trained using systems and methods in accordance with the present invention. Visual stimuli may be presented to a test subject. Measurements relating to the performance of the subject, such as stability information, eye movement data, physiological information, or other information, may be made both with and without visual stimuli being provided to a subject. Similar measurements may be made while the subject visualizes the visual stimuli, and the collected data may be compared to evaluate the subject's ability to visualize visual stimuli. Secondary stimuli may also be provided to subject as part of this process, or mental activities may be required by subject as well.
摘要:
The contrast sensitivity of an individual may be tested and/or trained using a plurality of circular contrast zones. The individual may select the circular contrast zone having a different degree of contrast than the other circular contrast zones. For example, the individual may select the circular contrast zone having the highest or lowest contrast of a displayed plurality of circular contrast zones. A plurality of circular contrast zones may be displayed with a spatial arrangement that facilitates inputting a selection of one of the plurality by the individual. A variety of input devices may be used to receive a selection from an individual. Both the accuracy and speed of an individual's contrast sensitivity may be tested and/or trained in accordance with the present invention.
摘要:
The present invention tests and/or trains the visual sensitivity of a subject using adaptable visual indicia. One or more visual indicia possessing a visual trait are displayed to the subject. The displayed visual indicia possessing a visual trait may be adjusted to determine when a subject can and cannot be perceived by the subject. A displayed visual indicia may be adjusted in its size, rate of movement, direction of movement, location of display, duration of display, or other characteristic. To determine whether a subject correctly perceived the visual trait possessed by a displayed visual indicia, an input may be received from the subject. If an input received corresponds to the visual trait possessed by the displayed visual indicia, the subject may be determined to have correctly perceived the displayed visual indicia and the visual trait.
