ABSTRACT:
An arrangement for enhancing vision and/or hand-eye coordination includes a foldable or bendable sheet. The sheet carries a circular array of annular pads, and a light-emitting diode fits in the center of each pad. The pads and light-emitting diodes can be connected to a microprocessor which, in turn, can be connected to a display unit. The microprocessor can be programmed to illuminate the light-emitting diodes in different sequences. The sheet is suspended and a subject stands in front of the sheet. As different light-emitting diodes are illuminated, the subject attempts to follow the motion with her/his eyes. Alternatively, the subject attempts to extinguish an illuminated light-emitting diode by touching, or propelling an object against, the associated pad. The microprocessor can establish a score or rating for the subject, and the results can be shown on the display unit. In exercise or training regimes where the subject must focus on an object, the sheet can be provided with a central opening which permits the subject to look through the sheet and focus at virtual infinity. The opening can also accept a unit which instead allows the subject to focus at optical infinity. In exercise or training regimes where the subject propels an object towards the sheet, the sheet may be provided with small microphones which can record the location and strength of impacts.
