Summary: We develop a geometrical acceleration scheme for the von Neumann-Halperin alternating projection method, when applied to the problem of finding the projection of a point onto the intersection of a finite number of closed subspaces of a Hilbert space. We study the convergence properties of the new scheme. We also present some encouraging preliminary numerical results to illustrate the performance of the new scheme when compared with a well-known geometrical acceleration scheme, and also with the original von Neumann-Halperin alternating projection method.
