ABSTRACT:
A saccadic enhancer apparatus which will operate to improve and develop accurate saccadic fixation for a user by providing horizontal, vertical, oblique and circular patterns for the user to observe. The enhancer employs a timing generator which produces a plurality of selectable time periods during which period a particular selected pattern will be provided. The patterns selected are implemented by a plurality of LED devices which are arranged on a display screen according to the patterns desired. The pattern to be implemented is selected by a selector switch and in the case of a horizontal line pattern the LED display operates from left to right and from right to left for the selected time period. When the circular mode is selected a circular pattern is provided which moves in a clockwise or counter clockwise direction and at the end of a complete scan, a smaller circular pattern is switched to. The switching between the larger diameter pattern and the small diameter pattern is automatically accommodated by the apparatus.
