Testing/training visual perception speed and/or span

A method for measuring the visual perception span and/or speed of a subject, the method comprising:

• orienting the subject within view of a display device and within reach of an input device, wherein
• the display device comprises a plurality of display portions in a two-dimensional arrangement, each of the plurality of display portions being capable of activation independent of the other display portions;
• and
• the input device comprises a plurality of input portions in a two-dimensional arrangement corresponding to the two-dimensional arrangement of the plurality of display portion, each of the plurality of input portions capable of registering an input independent of the other input portions;
• causing the display device to activate a subset of the plurality of display portions to render a two-dimensional representation viewable to the subject, the activation of the subset of the plurality of display portions lasting for a first period of time;
• registering any inputs provided by the subject at a subset of the plurality of input portions of the input device during a second period of time;
• and
• determining the amount of correspondence between the subset of display portions activated during the first period of time and the subset of the plurality of input portions registering inputs during the second period of time.

A system for testing or training the visual perception span and/or speed of a subject, the system comprising:

• a display device having a plurality of display portions arranged in a two-dimensional lattice, each of the portions capable of independent activation;
• a touch-sensitive input device having a plurality of input portions arranged in a two-dimensional lattice corresponding to the plurality of display portions on a one-to-one spatial basis, each of the input portions capable of independent receipt of an input;
• a testing unit operably connected to the display device and to the touch-sensitive input device, the testing unit operable to:
• cause the display device to activate, for a first period of time, a subset of the display portions to display a first amount of visual information in a two-dimensional figure comprised of activated display portions to the subject;
• cause the display device to cease to present the two-dimensional figure to the subject;
• cause the input device to receive for a second period of time any inputs from the subject provided to any of the plurality of input portions;
• compare any inputs received at any of the plurality of input portions during the second period of time to the subset of display portions activated during the first period of time to determine the degree of correspondence between any input received and the activated display portions.
