This multi-touch musical wall was developed during my internship at Moment factory to allow several players to play and compose music, even without musical knowledge.
A laser scanner detects the position of the hand of users and sends it to a computer. Algorithms analyses the movement and translate it in real time visually (lines and shapes) and musically (melody and chord).
The notes played depend of the others notes played at the same time, of the position of the hands, of the speed, the angle and the velocity of the movement. When a player drawn a melody, he can replay it, move it to have highest or lowest notes, harmonized it with others line or chord. Playing with this wall is physically and mentally very intuitive, and everybody can easily compose music.
