This innovative controller challenges conventional accessibility solutions by offering dedicated left- or right-handed configurations, optimizing precision and comfort for unilateral arm users. Its streamlined layout condenses directional inputs, triggers, and action buttons into an intuitive thumb-reachable matrix, with tactile ridges preventing accidental presses. The angled base stabilizes on flat surfaces, while weighted internal components counterbalance operation forces. High-sensitivity modular buttons allow pressure customization for partial-hand users.
