Hello I have a tactile screen with objects on it (each one having 3 different points of contact from the others). I am supposed in javascript only to :

• associate a 3 point touch to an object
• recognize the addition - suppression of an object on the screen
• recognize the translation and rotation of the objects.

My code is supposed to replace an old tuio implementation. Does any one have some leads to code I could take as a start before I reinvent the weel with the multi touch interaction API… thanks a lot
