Coaches, physiotherapists, neuro-athletic specialists, clubs and facilities use it to train how athletes perceive, decide and move under changing conditions. You define the goal. You design the task. You coach the movement. The app runs the system and returns the results. START IN SECONDS Choose from 400+ ready-to-use exercises for performance, neuro-athletic, rehabilitation, education and group settings. Adjust the task, save your preset and train. DESIGN YOUR OWN TASK Build custom exercises from our open training programs. Set the visual, auditory and tactile cues, the timing and the rules. Combine exercises into complete sessions with breaks and loops. ADVANCED CONTROL FOR ROXPROX LASER Set the laser-beam sensing distance from 10 to 150 cm (4 to 59 in), brightness and blink speed, and show letters, numbers and symbols on the LED matrix.
