An electronic device for processing image data, particularly image data pertaining to medical procedures, includes a user interface with force feedback ( ) corresponding to tool reactions, a &ldquo;collision&rdquo; module ( ) 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 ( ) 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 ( ) 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 ( ) is balanced by reaction force.
