An efficient application has been developed to detect close obstacles using a single smartphone camera and give speech information to vision impaired people. The proposed algorithm uses a simple technique aimed at measuring the local estimated image defocussing to roughly estimate its closeness to the camera. Preliminary results of the developing system are presented.
