Resumen

Scanning with ocular movements has been reported as an efficient tactic in rehabilitation of patients with visual neuro-pathways diseases. Neuroplasticity is reported as a possible cause of this particular therapy method in humans with delicate behavior measurement. Therefore, we propose the implementation of a control algorithm based on G-language to control a novel servo-mechanized laser device for rehabilitation in visual neural-pathways diseases, like hemianopia, quadrantanopia and scotomas based on saccadic movements using two designed programs. The first one enables the medics to create audiovisual stimuli sequences and the second one runs the created multi-sensorial therapy during a desired time between 20 and 60 minutes. The algorithm will control a device that mainly consists in a red laser pointer, two servos and nine buzzers, according to the previous-designed sequence, based on visual deficiencies of each patient. The laser pointer, used to present the visual stimuli on a black background and it is controlled with a two degrees-of-freedom servomotors array; forward kinematics calculations are used to control it. The instructions (buzzer number, zenith and azimuth coordinates) are sent to a microcontroller via USB with a USB to serial driver circuit and virtual COM port.
