Am\u00e9liorations possibles<\/span><\/p>\nLes valeurs des positions des doigts ou de la paume de la main renvoy\u00e9es par Max ne sont pas tr\u00e8s fiables, elles varient tout le temps, ce qui est assez restreignant lorsque l’on essaie d’assigner par exemple \u00e0 un intervalle une fr\u00e9quence donn\u00e9e.<\/span><\/p>\nOn pourrait rajouter des param\u00e8tres pour prendre en consid\u00e9ration la capacit\u00e9 du Leap Motion \u00e0 d\u00e9tecter le mouvement des doigts. H\u00e9las, on se heurte l\u00e0 aussi \u00e0 des probl\u00e8mes de pr\u00e9cision et de sensibilit\u00e9.<\/span><\/p>\nOutre les d\u00e9fauts de conception et les impr\u00e9cisions musicales, nous pouvons tenter d’am\u00e9liorer notre ma\u00eetrise de cet instrument de musique assez particulier.
