An abstract linkage is a one dimensional simplicial complex L with a positive number `(vw) assigned to each edge vw. A planar realization of an abstract linkage (L, `) is a mapping φ from the vertices of L to C so that |φ(v) − φ(w)| = `(vw) for all edges vw. We will investigate the topology of the space of planar realizations of linkages. You may think of an abstract linkage as an ideal mechani...

Virtual Worlds (VW) have gained popularity in the last years in domains like training or education mainly due to their highly immersive and interactive 3D characteristics. In these platforms, the user (represented by an avatar) can move and interact in an artificial world with a high degree of freedom.
