An electronic device for processing image data, particularly image data pertaining to medical procedures, includes a user interface with force feedback (4) corresponding to tool reactions, a "collision" module (18) for estimating a point of intersection between a straight line embodying a displacement derived from the action of the tool and a surface mesh of a given object, and an internal forces module (16) which estimates internal forces exerted on nodes of a first part of at least a volume mesh of the object, on the basis of a displacement applied on nodes pertaining to the surface mesh containing a point of intersection, of boundary conditions, and of node tensors and link tensors, from matrices of rigidity, and a reaction module (20) for determining the reaction force of the object corresponding to its deformation estimated on the basis of the internal forces, such that the force generated by the user interface (4) is balanced by reaction force.
