L'invention concerne un système de jeu doté d'une « balle » invisible, l'emplacement de la balle par rapport à la « batte » dans la main des joueurs étant indiqué au joueur par une communication non visuelle, par exemple par des effets sonores ou par un retour tactile. De ce fait, les joueurs ne sont pas obligés de regarder l'écran de l'ordinateur ni de porter des casques onéreux et inconfortables avec l'équipement vidéo de chaque utilisateur. De plus, en utilisant un moyen de communication non visuelle avec l'utilisateur, le système de jeu peut être utilisé par des joueurs mal voyants, voire des joueurs aveugles, et leurs convient particulièrement, et tous les joueurs quel que soit l'état de leur vue pourront utiliser leur sens autres que la vue.
