1. A method, comprising: presenting a graphical interactive object on a graphical user interface, GUI, of a touch sensing device, wherein the GUI is visible via a touch surface of the touch sensitive device; receiving touch input data indicating touch inputs on the touch surface of the touch sensing device, wherein the touch input data comprises positioning data x nt , y nt and pressure data p nt for each touch input, and determining from said touch input data: a first touch input from a first object at a first position on the touch surface, and a second touch input from a second object at a second position on the touch surface, and a third touch input from a third object at a third position on the touch surface, wherein said first, second and third objects are present on the touch surface during overlapping time periods; and while continuous contact of said first, second and third objects with the touch surface is maintained: calculating a geometric centre of mass, GCM, for said first, second and third touch inputs using positioning data x nt , y nt for said touch inputs; calculating a pressure centre of mass, PCM, for said first, second and third touch inputs using pressure data p nt for said touch inputs; comparing said GCM with said PCM; determining a movement vector k based on the result of the comparison; and moving the graphical interactive object in relation to the movement vector k.
